The first keypush will produce a character on the screen which will be replaced with the required character when thesecond key is pushed, the cursor with then move one place to the right.&Note: The CASE SHIFT key is used to access lower case letters.Section 13-3Example: To select the letter “N” until the flashing “FUNC” is displayed. , the number “4” will be displayed, ï, the desired “N” character will bedisplayed and the cursor will move one position to the right. The flashing “FUNC” legend will continue toflash, if it is not required further for it to be removed from the LCD.Example: To select the letter “e” until the flashing “FUNC” is displayed. , the number “5” will be displayed, to instruct the CPU that a lowercase letter is required (CASE SHIFT) ñ, the desired “e” character will be displayed and thecursor will move one position to the right. The flashing “FUNC” legend will continue to flash, if it is notrequired further for it to be removed from the LCD.
106(14) Configuration menuThe configuration (CONFIG) menu is used to set fundamental operating parameters and other variableswhich do not appear in any other menu heading.BEEP Confirmation & error toneLAMP LCD & keypad illuminationCONTRAST LCD contrast adjustmentPOWER-SAVE Delay & cycle power saveAUTO PWR-OFF Auto inactivity power offREMOTE BPS RS232 baud rateRMT-ID Computer control addressFREQ DISP Frequency readout on/offWRITE PROT Global write protectOPENING MESSAGE Change the power-up message14-1 CONFIG BEEPThe AR8200 emits confirmation ‘beeps’ while the keypad and sidekeys are used. A ‘HIGH’ pitched beep indicates correct operationwhile a ‘LOW’ pitched beep indicates that an error or unexpectedentry has taken place. The volume of the beep is independent ofthe main volume control and can be separately defined. It isrecommended that the beep facility be enabled, especially in theearly days while gaining familiarity of the receiver.Beep is setup in the CONFIG menu. To access the configmenu . The first item in theconfig menu is “BEEP”, the default is beep on with a volume level of 09. Use the main dial or ï ðkeys to vary beep level between the range of OFF and 01 to 09 with 09 being the loudest. The key may be used as a short cut to 05. to accept the data and return to a standard display. Alternatively to abort entry or ò to move to the next item on the config menu (LAMP).14-2 CONFIG LAMPThe AR8200 is equipped with high intensity green LEDs to illuminate the LCD and front panel keypadwhen operating in areas of low level lighting.While the AR8200 is switched on and connected to an external power source such as the chargeror d.c. lead, the lamp will be PERMANENTLY ON and cannot be switched off. The lamp will go outwhen the AR8200 is switched off (when the batteries are being charged etc).Section 14, 14-1, 14-2
107The lamp may be configured in three ways:AUTOThis setting is relevant when operating from internal batteries only. The lamp will automatically illuminatewhen the front panel and side panel keys are used. The lamp will remain illuminated for a further fivesecond after the last key push and will then switch off. This is a good compromise setting for bestvisibility and battery life.CONTThis setting is relevant when operating from internal batteries only. The lamp will CONTinuouslyilluminate the front panel and side panel keys. The lamp will only extinguish when the AR8200 isswitched off. Of course continuous operation of the lamp will drain the internal batteries more quickly.OFFThis setting is relevant when operating from internal batteries only. The lamp remains permanentlyextinguished, this is useful to maintain maximum battery life when used in areas of high light levels.The LAMP is setup in the CONFIG menu. To access the config menu . ò to move the cursor to the “LAMP” selection point. Use the main dial or ï ðkeys to toggle the lamp between AUTO (default), CONT and OFF. The key may be usedas a short cut to AUTO. to accept the data and return to a standard display. Alternatively to abort entry or ò to move to the next item on the config menu (CONTRAST).14-3 CONFIG CONTRASTThe AR8200 is equipped with variable LCD contrast which is adjustable in 32 steps to provide bestvisibility under different viewing angles, extremes of ambient light & temperature (and between sets dueto variation).The default setting for contrast is 14. The display generally becomes too dark to read around 20 and toofeint around 02, the key may be used as a short cut to 14.The CONTRAST is setup in the CONFIG menu. To access the config menu . ò twice to move the cursor to the “CONTRAST” selection point. Use themain dial or ï ð keys to vary the contrast level to achieve best visibility. to accept the data and return to a standard display. Alternatively to abort entry or ò to move to the next item on the config menu (POWER-SAVE).Section 14-2, 14-3
10814-4 CONFIG Power saveThe POWER SAVE facility may be used to help the receiver to operate for longer periods of timebetween battery recharging. Power save is default OFF to prevent confusion while the AR8200 is in a“dormant” cycle as the receiver is effectively asleep and only wakes up for short periods to check foractivity before going to sleep and becoming dormant again.&Note: While in a dormant state (waiting to cycle), the AR8200 behaves sluggishly.When power save is ON, the AR8200 will automatically switch ‘off and on’ but the display will appearpermanently on as only the AR8200 “receive” circuitry is switched off and on (switching the receiver offfor short periods of time is what saves power!), the microprocessor is left on permanently but in areduced operating condition.When activated, two parameters may be varied to affect the way the receiver behaves, these are“DELAY” and “CYCLE”.DELAY: This parameter determines how long the AR8200 will remain active before going tosleep and becoming dormant and is timed from when the squelch last closed or keypad was lastused. The available range is 01 to 30 seconds plus OFF (default off). When OFF, the powersave does not operate. The key may be used as a short cut to OFF.CYCLE: When the receiver becomes dormant (delay has expired), the cycle parameterdetermines how long the AR8200 will remain dormant before its ‘wake up’ period begins. If atransmission takes place while dormant it will be missed, if however a transmission occursduring the wake up period, the AR8200 will continue to monitor until the transmission ends andDELAY / CYCLE takes place again. The available range is 0.5 to 9.5 seconds (default 3.0seconds). The key may be used as a short cut to 3.0 seconds.The POWER SAVE parameters are setup in the CONFIG menu. To access the config menu . ò three times to movethe cursor to the POWER SAVE “DELAY” selection point. Use themain dial or ï ð keys to vary the delay value, the keymay be used as a short cut to OFF. ò to move the cursor to the POWER SAVE “CYCLE”selection point.Section 14-4
109Use the main dial or ï ð keys to vary the cycle value, the key may be used as a short cutto 3.0 seconds. to accept the data and return to a standard display. Alternatively to abort entry or ò to move to the next item on the config menu (AUTO PWR-OFF).14-5 CONFIG Auto power offAn auto power off facility is available to switch the AR8200 off automatically after a programmable periodof squelch inactivity, this prevents the batteries from becoming flat when monitoring a completely inactivefrequency.&Note: Be careful how you use auto power off as it might catch you out one day (if a shortauto-power-off period has been set), auto power off setting is not cancelled with power off / on…if the AR8200 appears to switch itself off for no reason, check to make sure that you haven’tenabled auto power off (there is no associated LCD legend).AUTO POWER OFF is setup in the CONFIG menu. To access theconfig menu . ò fivetimes to move the cursor to the “AUTO PWR-OFF” selection point.Use the main dial or ï ð keys to vary the time between 0.5 hoursto 9.5 hours in 0.5 hr increments, the key may be usedas a short cut to OFF.When the AR8200 squelch closes, the CPU will wait the length oftime programmed in auto-power-off before automatically switchingthe AR8200 off. If the squelch opens again before auto switch off time has elapsed, the radio will notpower down and the counter will be reset (i.e. an open squelch defeats auto power off). to accept the data and return to a standard display. Alternatively to abort entry or ò to move to the next item on the config menu (REMOTE BPS).14-6 CONFIG REMOTE BPSThe REMOTE BPS menu is used to configure the RS232 computer control settings as it is important thatthey exactly match those of an associated computer connection or another AR8200 (connected via theoption socket and optional leads).The REMOTE BPS parameters are setup in the CONFIG menu.To access the config menu . ò six times to move the cursor to the “REMOTE BPS”selection point. Use the main dial or ï ð keys to vary the RS232baud rate between 4800bps, 9600bps and 19200bps. The key may be used as a short cut to the default of9600bps.Section 14-4, 14-5, 14-6
110 ò to move the cursor to the “RMT-ID” selection point. Use the main dial or ï ð keyschange the AR8200 RS232 IDENTIFICATION ADDRESS when multiple units are connected to thesame port.It is possible to connect up to 99 units at once, each radio being assigned a different address. The valueis adjustable between 00 and 99, the default is 00. The key may be used as a short cut 00.&Important note: It is extremely important to set the RMT-ID to 00 for normal operationof the RS232 connection and clone of data between radios. to accept the data and return to a standard display. Alternatively to abort entry or ò to move to the next item on the config menu (FREQ DISP).14-7 CONFIG FREQ DISPIt is possible to instruct the AR8200 NOT to display frequencies while in memory read, search and scanmodes (should you wish for prying eyes not to see specifically what you are listening to). Liberal use of‘text comments’ is recommended if you disable frequency display (turned it off) unless you choose tohave really anonymous operation!&Note: Frequency display will be provided in VFO and VFO search and VFO scan even withthe frequency display disabled.The FREQUENCY DISPLAY parameters are setup in the CONFIGmenu. To access the config menu . ò eight times to move the cursor to the “FREQ DISP”selection point. Use the main dial or ï ð keys to toggle betweenON and OFF. The key may be used as a short cut to ON(which is default). to accept the data and return to a standard display. Alternatively to abort entry or ò to move to the next item on the config menu (WRITE PROT).14-8 CONFIG GLOBAL write protectIt is possible to globally write protect the entire AR8200 data storage, this prevents memory entry, searchbank programming, loading of data via the option socket, loading of data from the optional EM8200 etc.Use this feature carefully.Should you wish to leave your AR8200 safe in the knowledge that no-one will ‘mess it up’ (wellmaybe!)… toggle global write protect on.The global “WRITE PROTECT” status is setup in the CONFIG menu. To access the config menu . ò nine times to move the cursor to the “WRITE PROT”selection point.Section 14-6, 14-7, 14-8
111Use the main dial or ï ð keys or key to toggle between ON and OFF (the default is off). to accept the data and return to a standard display. Alternatively to abort entry or ò to move to the next item on the config menu (OPENING MESSAGE).14-9 CONFIG Opening messageIt is possible to display a welcome message while the AR8200 is powering up and collating its ‘boot-up’information. There are three options for opening message:NORMNormal message is displayed at switch-on: WELCOME TO THE NEW WORLD OF AR8200.QUICKBlank screen at switch-on.USERFour lines of 12 characters may be entered for display at switch-on. Initially they are configuredfor you to enter OWNERS name and PHONE NUMBER but all lines may be over-written.The “OPENING MESSAGE” is setup in the CONFIG menu.To access the config menu . ò ten times to move the cursor to the“OPENING MESSAGE” selection point. Use the main dial orï ð keys to toggle between NORM / QUICK / USER.The key may used as a short cut to NORM (which isthe default). to accept the data and return to a standard displayor to abort entry.Alternatively if you have selected USER and wish to change the text comment ò to access thetext input menu for the opening menu.You may change all four lines of text in the usualmanner. Please refer to section 12-1 of thismanual for further information regarding text input. to accept the data and return toa standard display or to abortentry. When the AR8200 is switched off and backon again, the new opening message will bedisplayed.Section 14-8, 14-9
112(15) Band scopeThe AR8200 is equipped with a flexible band scope function which is capable of graphically displayingband activity. The maximum frequency span width is 10 MHz, you may zoom in on activity to a spanwidth of 100 kHz. Centre frequency is displayed and a marker may be manipulated to ascertain thefrequency of activity using the graphical display. One trace may be saved to memory for recall at a latertime and may be overwritten at will. The trace may also be saved and loaded from the optional EM8200external memory slot card.&Note: Priority operation is disabled when the band scope is in operation. Audio is muted.The optional RU8200 is inoperative when the band scope is in operation.It is suggested that the band scope facility is ‘experimented with’ on a constantly active band such asVHF Band-II broadcast.15-1 Starting the band scopeTo start the band scope . The frequency span width will be set to 10 MHz with the lastfrequency displayed in 2VFO, search, scan or memory read mode being used as the centre frequency.AUDIO IS MUTED.The centre frequency is displayed in the top left of the LCD, one pixel will be missing from the centre ofthe graphical base line indicating centre frequency position.A progress cursor which comprises of a single pixel on the graphical base line travels from left to rightupdating the band scope display… this confirms that the band scope is IN OPERATION (especiallyuseful when a trace is simply being updated or no signals have been located).The frequency span width is displayed in the upper right corner of the LCD, at default this is 10 MHz.The frequency marker legend “MKR” is displayed on the second line of the LCD, the marker is alsorepresented graphically by an upturned triangle (initially placed above-centre of the graphical trace).When first activated, the centre and marker frequencies are the same (but may be altered).The graphical trace is built-up from left to right. If no transmissions are encountered the display willsimply form a horizontal line around two pixels in height. When activity is located, vertical lines areproduced on the LCD, the stronger the signal the higher the line.&Important: To monitor the transmission of the marker frequency and hold the key. The progress of the scope is halted when the key is held. Squelch settinghas no effect on the band scope trace.Section 15, 15-1
11315-2 Exit from band scopeTo exit the band scope or or .15-3 Setting frequency span width (waveform enlargement)The frequency span width may be adjusted between the limits of 10 MHz (default) to 100 kHz usingthe ñ ò keys. The span widths available are:10 MHz 35s for full trace approx.5 MHz 20s for full trace approx.2 MHz 10s for full trace approx.1 MHz 6s for full trace approx.500 kHz 3s for full trace approx.200 kHz 6s for full trace approx.100 kHz. 3s for full trace approx.When the frequency span width is altered, the trace restarts. to refresh the trace fromthe start.15-4 Moving the markerTo move the marker position use the ï ð keys, the channel step will be dependant upon the spanwidth resolution. To monitor the marker frequency and hold the key. The progress ofthe scope is halted when the key is held.15-5 Marker to strongest signal (peak search)To simplify operation, it is possible to ‘jump the marker’ to the strongest signal of the current graphicaltrace (peak search). and hold the key until the “«” legend is displayed indicatingthat the marker is set to the strongest graphical signal. and hold the key to monitorthe selected frequency. The ï ð keys may be used to hop between the strongest few transmissions. to disable peak search, the “«” will be removed from the LCD.&Note: If no signal is found above the background level (or if there hasn’t been time allowedfor a trace to form), peak search will not operate and an error beep will be emitted (if beep isenabled). This facility cannot be used with a span width of 100 kHz.Resolution is 10 kHz with a 12 kHz IFfilter selected (NFM or AM) so that onepixel represents 140 kHz at maximumsignal strengthResolution is 2 kHz with a3 kHz filter (USB, LSB, CW)Section 15-2, 15-3, 15-4, 15-5
11415-6 Entering a new centre frequencyTo enter a new centre frequency, simply tap the wanted frequency into the keypad. The legend“CENTRE FREQ” will be displayed on the top line of the LCD with entry taking place on the second line.To complete entry in MHz format . The marker will be automatically set to the centrefrequency but the frequency span width will be unchanged.15-7 Transfer of marker frequency to VFOThere are two ways in which the marker frequency may be transferred to VFO for long term monitoring.Transfer to 2VFO retaining VFO data to move marker frequency to 2VFO, receive mode and stepare those of the VFO.Transfer to single VFO with 10 kHz tuning stepHold the key then to transfer marker frequency to single VFO,receive will be that used in VFO mode but the tuning step will always be 10 kHz to allowsensible re-tuning in VFO mode for best reception of the transferred marker frequency15-8 Peak holdThe PEAK HOLD facility is used to build up an image of bandactivity over a period of time, the display is not totally cleared eachtime a trace is made, only strong signals are added.To toggle PEAK HOLD on/off ,the “HLD” legend confirms when peak hold is active.The ï ð keys may be used to move the marker position and key may be held to monitor activity on the markerfrequency.15-9 Saving active trace to memoryTo save the current trace to internal memory (for later retrieval) . It is suggested that the peak hold facilitybe employed before saving a trace so that it provides moremeaningful information.If the optional EM8200 is used, it possible to save four furthertraces to external memory. Refer to section 18-6-7 of this manualfor further information regarding this feature.Section 15-6, 15-7, 15-8, 15-9
11515-10 Loading stored band scope traces from memoryProviding a trace has been previously stored to memory, it is possible to recall it to display using the keysequence . The legend “RCV” (in the place of “MKR”) indicates that astored trace is currently being displayed.The AR8200 will no longer sweep the frequency range but the key may still be used to monitorthe marker frequency. Key in a new centre frequency to return to a real time band scope.It is possible to move the marker across the graphical trace using the ï ð keys. Waveform enlargementis available by changing the frequency sweep width using the ñ ò keys.If the optional EM8200 is used, it possible to load any one of fourfurther traces from external memory. Refer to section 18-6-7 ofthis manual for further information regarding this feature.Section 15-10
116(16) Sleep ¹It is possible to instruct the AR8200 to automatically switch-off after a predetermined time, this isparticularly useful if you know that you may be called away from the receiver or listen to it while inbed and don’t want the batteries to become completely flat.Use the key sequence to accesses the SLEEP menu.Use the main dial, ï ð keys or key to toggle sleepon/off. For convenience SLEEP is default ON when this menu isaccessed so that you have simply to access and exit the menu forsleep to be activated.Either to save the changes and exit the menuor ò to move the cursor to the sleep TIME menu. Usethe main dial to set sleep time in 1s increments or ï ð keys toincrement in 10 seconds, the range is between 1 and 120 minutes, is a short cut to 60 minutes (default).The AR8200 will automatically switch off after the programmed time has elapsed.To accept the data and activate sleep . The display will return to standard format andthe circular CLOCK legend ¹ will be displayed to remind you that automatic power off will take place.The next time that the AR8200 is powered on, the sleep facility will be automatically cancelled.Section 16
117(17) Option socketThe option socket is mounted on the right hand side of the cabinetunderneath the 12V d.c. input socket. The socket is protected fromdust by a grey rubberised case stopper which is hinged toward thefront of the cabinet. Gently lift the stopper from the rear edge toreveal the D-shaped metallic socket. Be careful to keep dust and dirtfrom this socket and to prevent liquid entering the AR8200 via thissocket. Ensure that no conductive material is allowed to short circuit thesocket which may damage the receiver.The option socket has three main uses:1. Connection of the optional CR8200 tape recording lead2. Connection of the optional CO8200 data clone lead3. Connection of the optional CC8200 computer control lead with level shift (available with imperial (PC98) & metric (DOSV) screws)Other signals are available via the option socket including detector output, mute and AGC.Typical pin-out of the optional leads are as follows:RED +4.2VBLACK RXDBLUE GROUNDBROWN MUTEORANGE AGCSHIELD GROUNDWHITE TXDYELLOW GROUNDGREEN AUDIO OUTGREY DETECTOR OUTPURPLE GROUNDOutput levels are as follows:MUTE CMOS (0V or 5V)AUDIO OUT Constant level into greater than 10k OHMSDETECTOR OUT Available in NFM & SFM, impedance 10k OHMSAGC 3.5V to 0.5V, impedance 10k OHMSRS232C TXD + RXD (levels to drive a level shift converter)&Note: The voltage output level to drive external RS232 isdeliberately below ‘H’ level. If connecting to an external I.C.,you must be aware of latch status.PSU 4.2V at 20mASection 17
11817-1 RS232 operationConnect the optional CC8200 computer control lead to the optionsocket and connect to a computer. The command protocol isprovided with the CC8200 on floppy disk as an Adobe AcrobatPDF file.The RS232 parameters may be defined using the CONFIG menu.Baud rates (transfer speed) may be set to 4800, 9600 or19200bps. It is also possible to set an ‘address’ to facilitateconnection of up to 99 AR8200 to a single port for customoperation, the addresses may be set between the limits of01 to 99 with 00 representing single radio operation.When operating from external RS232, the legend ¤ will be displayed on the LCD. Please refer tosection 14-6 of this manual for information on the CONFIG menu settings.17-2 CLONE of data via the option socketIt is possible to copy data (clone) between two AR8200 receives using the optional CO8200 clone lead,no computer is required.&Note: As clone of data takes a while, it is suggested that the receivers are connected toexternal power or at least that the NiCads are FULLY charged while cloning data. Do notprematurely terminate the clone of data in any way or data corruption may occur… do notswitch either AR8200 off, disconnect the CO8200 or disconnect power. Data can be copied ineither direction but the EM8200 is not supported, only INTERNAL data can be copied betweenradios.Connect each radio to the CO8200 lead and switch them on. The following table indicates the facilitiesavailable:ALL DATA All data is transferred from one radio to the other(approx. 8 minutes 30 seconds)SEARCH BANK A specific search bank is copied to the same or different banknumber of the second radio (approx. 3 seconds)ALL SEARCH All search banks are copied from one radio to the other keepingbank numbers the same (approx. 1 minute 30 seconds)MEM BANK A specific memory bank is copied to the same or different banknumber of the second radio. Ensure that the memory banks havethe same sizes allocated (dynamic memory bank resizing) or datamay be lost (approx. 30 seconds)ALL MEM All memory banks are copied from one radio to the other keepingbank numbers the same. Memory banks are handled as a ‘pair’(A/a, B,b etc). If memory banks are not the same size (dynamicmemory bank resizing), some data will be lost. (approx. 5 minutes)Section 17-1, 17-2
11917-2-1 How to clone dataEnsure that the RS232 baud rate is set to the same speed for bothradios and that the address is set to 00 on both units (refer tosection 14-6 of this manual for information on the CONFIG menusettings).a) Pick the radio which you wish to copy TO (target)First decide which unit will be used to receive (LOAD) the data. to access the “COPY RS232C” menu. The key acts as atoggle between “LOAD” and “SAVE” (the default is LOAD), alternatively use the main dial or ï ð keysto select LOAD.b) Decide WHAT you want to copy the ò key to move down the COPY RS232C menu, the cursorwill be flashing to the left of the item “ALL-DATA”. If you want to loadALL DATA , alternatively use the main dial or ï ðkeys to select the type of data you wish to load (copy) from the otherradio. .The bottom two rows of the LCD will display the legends “LOADING !!”and a number. The number will start counting downward when the copyprocess starts (when the other radio has been instructed to SAVE), themore data you have selected, the higher the number… for ALL-DATA thenumber will typically be 448.c) Configure the radio used to SAVEOn the second radio, to access the “COPY RS232C” menu.The key acts as a toggle between “LOAD” and “SAVE” (the default is LOAD), alternatively usethe main dial or ï ð keys to select SAVE. the ò key to move down the COPY RS232C menu, thecursor will be flashing to the left of the item “ALL-DATA”. If youwant to load ALL DATA , alternatively usethe main dial or ï ð keys to select the type ofdata you wish to save (send) to the other radio. Itis most important that the type of data selectedis IDENTICAL on both radios. .The bottom two rows of the LCD will display the legends “SAVING !!” and a number which will startSection 17-2-1
120counting downward to indicate that the copy process (clone of data) has started. When the numberreaches zero the copy process will have completed, both radios will revert to standard displays.&Note: If you make a mistake during programming, it is possible to the key to exit the menu. However, be careful and get it right in the first place…this is the best way of avoiding the possibility of data corruption.Write protectIndividual memory channel protect and search bank protect status is ignored, however global protect willprevent data being cloned between radios.Section 17-2-1
121(18) Slot card socketThe slot card is located in the bottom of the AR8200 cabinet and protected from dust etc by a door whichis hinged toward the back edge of the cabinet. To access the socket place the AR8200 on its back andopen the front edge of the protective door. Be careful to keep dust and dirt from this socket and toprevent liquid entering the AR8200 via this socket. Ensure that no conductive material is allowed to shortcircuit the socket which may damage the receiver.18-1 Optional slot cardsAny ‘one’ optional card may be fitted at any time. Do not use anything other than the ‘genuine’AOR slot cards.The slot card has five main uses:1. VI8200 Voice inverter (analogue) in 157 steps2. CT8200 CTCSS squelch & search3. TE8200 Tone eliminator in 256 steps4. RU8200 Chip based recording and playback, 20 seconds approx.5. EM8200 External extended memory, backup 4,000 memories, 160 searchbanks (can hold as much data as 4 x AR8200)Signal types depend upon the slot card fitted, these include:l 4.2V PSUl GROUNDl CARD RECOGNITIONl AUDIO INl AUDIO OUTl CARD CONTROL INl CARD CONTROL OUT18-1-1 Fitting the slot cardAlways switch the AR8200 off when inserting slot card. To accessthe socket place the AR8200 on its back and open the front edge ofthe protective door. With the AR8200 keypad facing upward, hold theslot card so that its label also faces upward. An arrow printed on the slotcard indicates the direction of entry into the AR8200, insert the connec-tor end of the slot card into the AR8200 (the end you will be left holdinghas groves to help grip). Without using excessive force, use a thumb to push the slot card fully intothe body of the AR8200 until it is slightly recessed into the bottom of the receiver. Close the hingedslot card compartment cover.&Note: The AR8200 will automatically recognise each optional slot card, there is no need toinitialise the option (except for the EM8200, see later).When slot cards are fitted, the AR8200 menu system dynamically changes to reflect the slot cardSection 18, 18-1, 18-1-1
122currently fitted. If however the AR8200 ‘thinks’ that a slot card option is fitted when it isn’t, accessthe slot card menu and disable the option.You may wish to leave certain items selected if they are not affecting current operation in order tominimise reprogramming when slot cards are inter-changed at a later time.18-1-2 Removing the slot cardAlways switch the AR8200 off when removing a slot card. To access thesocket place the AR8200 on its back and open the front edge of the protectivedoor. An EJECT slider is mounted on the left hand side of the AR8200 cabinet.With the AR8200 keypad facing upward slide the EJECT control toward the sidekeys of the AR8200, the thumb is best for this purpose… hold the thumb of theother hand one or two centimetres (one inch) from the bottom of the slot card toprevent it shooting out of the AR8200 and falling on the floor.The stiffness of the cards varies and may be tighter when used for the first fewtimes, the EJECT slider needs quite a push but don’t use excessive force ortools!18-2 VI8200 optional voice inverter slot cardThe VI8200 enables the AR8200 to recover intelligible audio from certain types ofanalogue transmission which would otherwise sound scrambled. They operate bysplitting up the audio spectrum and ‘flipping’ the upper and lower tones around acertain frequency point. The VI8200 enables 157 different ‘flip points’ to beselected in the frequency range of 2.4 kHz to 5.6 kHz.Insert the VI8200 slot card and switch the AR8200 on, select VFO mode. to access the slot card option menu. The AR8200 will haverecognised that the VI8200 has been fitted so will present the voice inverter menu.The legend “VOICE INVERT” confirms selection of the voice inverter menu. the key to toggle the voice inverter on/off (default on). Use the main dial orñ ò keys to make selection of tone in 157 steps from 0 to 156, the ï ð keys are used to incrementselection by 10.To accept the data input (when audio is intelligible) , alternatively to abort entry .Refer to the relationship table between value and ‘flip’ frequency: Frequency (kHz) 2.4 2.8 3.2 3.6 4.0 4.4 4.8 5.2 5.6 6.0 6.15 Inverter value 0 37 64 86 102 116 128 138 146 154 156When the voice inverter has been activated and you exit from the voice inverter menu back to VFO, thelegend “v 68” will be displayed in the bottom right corner of the LCD. The legend “v” indicates that theSection 18-1-1, 18-1-2, 18-2

This isachieved as the default is set to voice inverter ON (by accessingthe voice inverter menu) so that every time the voice invertermenu is accessed, the voice inverter is automatically activated.1. For example, assume that the voice inverter iscurrently OFF. to access the voice inverter menu, the voice invertermenu cursor will moveto “ON”.2. to revert to VFO mode with the voice inverter on.3. to immediately toggle the voice inverter off.The sequence then repeats each time you .&Note: Using the voice inverter to monitor normal transmissions willcause them to distort and sounds rather like tuning across a busy shortwave band using USB.18-3 CT8200 optional CTCSS slot cardThe CT8200 enables the AR8200 to search for 50 CTCSS tones which may be inuse on the current receive frequency and to save a specific CTCSS tone (fromthe 50 tones available) into each VFO, each search bank and every memorychannel individually. CTCSS is used by many amateur band repeaters, publicutilities and private mobile radio services where shared resources are used,CTCSS ensures that operators only hear traffic intended for them.Insert the CT8200 slot card and switch the AR8200 on, select VFO mode. to access the slot card option menu. The AR8200 will have recognised that theCT8200 has been fitted so will present the CTCSS menu.The legend “CTCSS” confirms selection of the CTCSS menu. the key or use theñ ò keys to toggle the CTCSS facility between OFF / ON / SRCH (default is off).

124While in the CTCSS menu, to activate the CTCSS facility (the LCD legend “ON”is displayed in reverse highlight).Use the main dial or ï ð keys to make selection of CTCSS tone from the 50 available, the valuecannot be adjusted when the menu is set to “OFF”. The current CTCSS tone is displayed on thelast-but-one line of the LCD, the legend “«” is displayed to the left of the CTCSS frequency whenthe current receive frequency is using the displayed CTCSS tone, this assists manual selection ofthe correct tone.To accept the data input , alternatively toabort entry . The selected CTCSS tone maybe used in VFO (separate CTCSS tones may be held in eachVFO) and independent CTCSS tones saved in each searchbank and memory channel.While in VFO, the legend “CTC” is displayed in the lower leftcorner of the LCD to indicate that CTCSS is active. The audio willbe completely muted until a transmission occurs which containsthe specified CTCSS tone even when the squelch is set fullyanti-clockwise (open), it is normal for the occasional ‘splutter’ to be produced as ‘CTCSS typefingerprints’ naturally occur in everyday transmissions and background noise.Scan & search banks: It is even possible to scan & search with the squelch open when CTCSS isactive but scan/search rates will be reduced significantly. To achieve the best speeds, set thesquelch until the “S” legend is extinguished in the usual manner.Refer to the CTCSS table of available tones:94.8 100.0 103.5 107.2 110.9114.8 118.8 123.0 127.3 131.8136.5 141.3 146.2 151.4 156.7162.2 167.9 173.8 179.9 186.2192.8 203.5 210.7 218.1 225.7233.6 241.8 250.3 67.0 71.974.7 77.0 79.7 82.5 85.488.5 91.5 97.4 69.4 159.8165.5 171.3 177.3 183.5 189.9196.6 199.5 206.5 229.1 254.1To switch CTCSS off, access the CTCSS menu to highlight thelegend “OFF” then .18-3-2 CTCSS searchIf you are uncertain what CTCSS frequency is in use, but you think there may be one present, you maySection 18-3-1, 18-3-2

While in 2VFOmode, the standby frequency will be replaced with the legend“CTCSS 205.5 Hz” when a CTCSS tone of 205.5 Hz has been located, otherwise the appropriateCTCSS frequency will be displayed.Each memory channel, VFO and search bank can hold different CTCSS frequencies and differentsettings of CTCSS squelch and CTCSS search (i.e. you can have CTCSS search active in VFO butCTCSS squelch active in memory channels).If you are uncertain where CTCSS may occur and wish to experiment with CTCSS search, simplyactivate the CTCSS SEARCH facility while monitoring a broadcast frequency(such as Band-II) which has a rich audio range (playing music etc).&Note: As CTCSS search has to check all 50 possible frequencies,it may take up to 15 seconds for the CTCSS tone to be identified.18-4 TE8200 optional tone eliminator slot cardThe TE8200 enables the AR8200 to ignore certain transmission tones whichwould otherwise stop the scan and search processes. Pilot tones are oftentransmitted by public utility services and railways making their transmissionstroublesome and fatiguing to monitor without the use of the TE8200. There are256 values for the tone eliminator ranging from 0 to 255 representing a frequency range of 0.4 kHzto 4.2 kHz.Insert the TE8200 slot card and switch the AR8200 on, select VFO mode. to access the slot card option menu.

Operation continues as normal with thetone eliminator active, however if a transmission is encountered whichcontains a ‘pilot tone’ which matches the current setting of the tone eliminator,the squelch will close allowing the scan and search processes to continue…i.e. the AR8200 will NOT think that it has found an active receive frequency orblank carrier.&Note: The tone eliminator does not remove whistles from theloudspeaker, it purely allows scan & squelch to continue unhindered.18-5 RU8200 optional record & playback slot cardThe RU8200 enables around 20 seconds of audio to be recorded to a chip within the RU8200 forplayback at a later time. The chip may be recorded to time and time again overwriting the previousrecordings. The recording may be played back over and over, very useful if you have grabbed aninteresting recording! The RU8200 may be used in VFO, scan, search and memory read modes.Insert the RU8200 slot card and switch the AR8200 on, select VFO mode. to access the slot card option menu.

In fact the EM8200 can hold the entire contents of the AR8200including environmental operating data and band scope FOUR times in EM8200 locations 0, 1, 2 &3. It is not necessary to save ALL data, you can specifically choose what data is to be backed upand to which location.Section 18-5-1, 18-5-2, 18-6
128&Note: You cannot scan or search the backup information, datamust be loaded back into the AR8200 before these processes can be activated.&Important note: Never remove the EM8200 with the AR8200 switched on, especiallywhile data is being saved / loaded to and from the AR8200 or data corruption may occur.Saving all data takes some time, it is recommended that external power be used whilecopying large volumes of data to / from the EM8200 (or at least be sure that the batteriesare well charged). No liability in any form will be accepted in respect of data savedto / loaded from the EM8200 option.&Note regarding write protect: If the write protect has been globally set to ON(ALL PROTECT) in the configuration menu ( ), data load willbe unsuccessful and no data will be loaded. Individual memory channel protect, memorybank protect and search bank protect will be ignored during data load from the EM8200.&Note regarding possible NOISE: A small increase in ‘noise’ may be noticed while theEM8200 option is fitted inside the AR8200, this will disappear when the EM8200 is removedfrom the receiver. If signals are very weak or noise is a problem, temporarily remove theEM8200 option.The following table indicates the data types which may be saved to / loaded from the EM8200:1ALL-DATA All memories, search banks, band scope andenvironment data2ALL-MEM All memory channels3MEM-BANK One specified memory bank4ALL-SRCH All search banks5SRCH-BANK One specified search bank6B-SCOPE Band scope data18-6-1 Initialising (formatting) the EM8200 before useThe EM8200 has been tested during manufacture but is not fully formatted. Before you use the EM8200for saving real data, you must format the memory, this only needs to be carried out once in the life of theEM8200 (similar to formatting a computer disk drive).To format the memory, simply execute a SAVE ALL to each of the four memory locations of the EM8200(0, 1, 2 & 3).If you do not format the memory, you will still be able to carry out SAVE ALL (item 1 in the table) but thespecific data saves (items 2, 3, 4, 5 & 6 will not operate). If you do not format the memory and laterattempt to use a specific memory save or load, an error beep will sound (if beep is enabled).To access the COPY EXT-MEM menu (which is used for the EM8200 data save / load and has beenselected dynamically in place of the COPY RS232C menu as the AR8200 recognises that the EM8200 isfitted) .

Check that you have search data programmed and that all frequencies are not locked out(PASS).19-3 Trouble shooting - Take note of the followingSelect scan cannot operate in conjunction with mode scan. Select scan is disabled when priority isengaged.Priority is disabled when the band scope is in operation. If a long DELAY time is set, priority ‘eats’away at delay time causing it to shorten. If the optional CT8200 slot card is in use, CTCSS SEARCHcannot operate with priority engaged due to the required CTCSS search time being quite long.Section 19-2, 19-3
138When POWER SAVE is on, response from the AR8200 may be sluggish and there will be periods ofno receive.If the key is being used to display a frequency with FREQUENCY OFFSET in use, this offsetfrequency cannot be stored into memory.The squelch may not operate promptly (as you may expect) when monitoring in USB, LSB, CW andNAM modes due the narrow bandwidths employed. This is a fundamental characteristic of the squelchcircuit. Audio may remain even though the “S” squelch legend may have disappeared for a couple ofseconds. It is suggested that LEVEL squelch be used as an alternative in this situation.There are no internal operator adjustments. In the unlikely event of servicing being required,please contact your dealer for technical assistance.(20) Optional accessoriesSlot cards:Five slot cards are available, only one may be fitted at a time.1.

There are many advantages and disadvantages to consider beforeconnecting an external aerial to your receiver. One interesting phenomena is that aerial theory and practice can be surprisinglydifferent. Keeping common sense in mind it is one of the few remaining areas for listeners to easily experiment and often achievefantastic results.Whip aerialThe supplied semi-flexible whip aerial should give adequate results for general hand-held operation on the VHF and UHF bands. A longer wire aerial or telescopic whip should be considered for listening to the short wave bands. The AR8200 is supplied with aferrite bar aerial for medium wave reception, for best results, rotate the receiver as the bar aerial is directional.Mounting locationIt is important to mount any external aerial as high as possible and in clear space although this is more important at VHFfrequencies than for short wave. If possible the aerial should have a clear path to the horizon. Results are usually disappointingwhen an installation is in a loft space.Long wire aerialsFor short wave reception a random length of long wire approximately 10 to 20 metres in length forms a good compromise. The wireshould be connected to the centre pin of a BNC plug then connected to the BNC aerial input on the top of the AR8200. If possibletry to locate the receiver close to a window so that the wire has the shortest and most direct run from the rear of the receiver to theoutside world.DisconeFor wide coverage in the VHF-UHF bands a compromise has to be met and the most popular aerial is a discone (AOR DA3000).Their appearance is like a large spider or umbrella without the covering material, the better models have about 16 elements.Typical usable coverage starts from about 25 MHz and extends continuously to 500 MHz 1300 MHz or even 2000 MHz. Thecoverage peaks and dips throughout it’s range as the elements interact to provide the widest possible coverage. Due to theirnecessary construction discone aerials are a little prone to “wind noise” due to vibration and possible damage in severe gales.FiltersA VHF civil AIRBAND FILTER is available (ABF125), this will help minimise the possible effects of breakthrough when listening toVHF airband in Band-II VHF high signal areas or when connected to external aerials.Earth systemsA separate EARTH connection made to the outer (braid) connector of the BNC plug may improve aerial efficiency and reduce noise.Suitable earth points include connection to a water pipe, central heating radiator or external earth rod. If fitting a separate externalearth rod, consider the implications carefully if your mains supply uses Protective Multiple Earth (PME) system. If in doubt consultan experienced electrician. Connecting an external earth wire may greatly reduce the local noise encountered when listening on theshort wave bands. It is very important to provide a good earth should you use an aerial tuning unit.A short length of thick gauge earth wire may be connected to a nearby central heating radiator or water pipe but never use a gaspipe for earthing. Ideally a separate earth rod should be used but the length between the receiver and rod becomes restrictive,if too long the earth system may well “pick up” noise rather than remove it.Section 21
140PropagationVHF and UHF transmissions generally only propagate relatively short distances when compared to short wave signals. For allintents and purposes they may be considered as line-of-sight plus a bit.Where as point to point communication between mobile users or when in built up areas may only be a couple of kilometres, aircraftat heights of 30,000 feet may be heard for many tens of kilometres (100 to 300 with the right conditions).Unlike VHF and UHF transmissions which generally propagate only on a localised basis (to the horizon plus a small amount), shortwave transmissions may travel for many thousands of kilometres. Depending upon the frequency in use, time of day, season of theyear and sun spot activity, transmissions may propagate completely around the World.Luckily the frequency spectrum of short wave is often reflected back down to Earth by the upper layer of the Earth’s atmospherecalled the ionosphere. When the reflected signals reach the Earth again they may either be received or reflected back up intospace. If lucky, they will be reflected by the ionosphere yet again down toward the Earth providing reception into another andpossibly more distant location. Depending upon the time of day and desired skip distance, different frequencies will be selected byRadio Amateurs and commercial users such as Oceanic Air Traffic.(22) SpecificationFrequency Range: 500 kHz to 2040 MHz(Actual frequency input 100 kHz to 2040 MHz,performance between 100 kHz to 530 kHz isnot guaranteed).Receive Modes: WFM, NFM, SFM, WAM, AM, NAM, USB, LSB, CWSensitivity: 500 kHz ~ 2.0 MHzAM: 3.50 µV (10dB S/N)2.0 MHz ~ 30 MHzSSB: 1.50 µV (10dB S/N)AM: 2.50 µV (10dB S/N)30 MHz ~ 470 MHzSSB: 0.30 µV (10dB S/N)AM: 0.70 µV (10dB S/N)NFM: 0.35 µV (12dB SINAD)WFM: 1.00 µV (12dB SINAD)470 MHz ~ 1 GHzNFM: 0.50 µV (12dB SINAD)WFM: 1.50 µV (12dB SINAD)1.0 GHz ~ 1.3 GHzNFM: 1.00 µV (12dB SINAD)1.3 GHz ~ 2.039 GHzNFM: 2.50 µV (12dB SINAD)Selectivity: SSB/NAM 3kHz (-6dB), 9kHz (-60dB)AM/SFM 9kHz (-6dB), 20kHz (-40dB)WAM/NFM 12kHz (-6dB), 25kHz (-40dB)WFM 150kHz (-3dB), 380kHz (-20dB)Power Consumption: 190mA (nominal), 145mA (stand by), 25mA (power save).4 x AA internal cells or 12V d.c. external supplyDimensions: 61(W) x 143(H) x 39(D) mmWeight: 196g (335g including NiCads)Memory channels: 1,000 (20 banks)Select scan channels: 50Priority channels: 1Section 22
