Menu operation

The menu can be accessed with the M button (short press).

Once in the main menu, the menu items will be displayed on the left-hand side of the screen. The currently selected menu item will be highlighted and current value for that menu item will be shown on the right. Also, at the bottom left side a number of the menu item will be shown, ranging from 01 to the highest number.

To find the menu item to access, the UP/DOWN arrow keys may be used, or the menu item number (see lists below) may be entered on the numeric keypad. For instance, to access the Demodu - demodulator mode a number 14 can be entered on the keypad.

Once the desired menu item is highlighted, pressing the Menu key will enter into that menu item.

Once the menu item is selected, pressing the up and down arrow keys will adjust the setting for that menu item. To confirm the selection, press the Menu key. To cancel the selection, press the EXIT key.

Main menu

The number in front of the menu-item-description is an menu item number that can be used for quick selection.

  1. Step - step of the frequency (in kHz), up/down buttons change frequency by this value, also you can only set a frequency that is multiple of this value. 2.50/5/6.25/10.00/12.50/25.00/8.33 are the steps that can be set by programming software, all other steps are extension from standard software, and can only be selected from this menu entry.
  2. Bandw - bandwidth used by transceiver and displayed in format ie. 12.5k (instead of N/W)
  3. TxPwr - radio output power (LOW/MID/HIGH)
  4. RxDCS - receiver Digital-Coded Squelch, if you enable this, squelch will only unlock if this code is being received. You can start a DCS/CTCSS scan while you are in this menu option by pressing * SCAN button
  5. RxCTCS - receiver Continuous Tone-Coded Squelch System, squelch will only unlock if this code is being received. You can start a DCS/CTCSS scan while you are in this menu option by pressing * SCAN button
  6. TxDCS - transmitter Digital-Coded Squelch, radio will send given code while transmitting
  7. TxCTCS - transmitter Continuous Tone-Coded Squelch System, radio will send given code while transmitting
  8. TxODir - transmitter frequency offset direction
  9. TxOffs - transmitter frequency offset value
  10. RxOffs - offsets the receive frequency by any specified amount for use with upconverters (in the range of 0-150Mhz). Allows to fine tune the frequency (1kHz resolution) as opposed to other implementations that use hardcoded offsets, this once set will also allow to tune below 18Mhz limit.
    • You can fine tune this setting in even smaller steps by changing Step setting to 0.01kHz and then use UP/DOWN buttons to alter RxOffs in increments of 0.01kHz.
    • TX is disabled when RX_OFFSET is set to protect the upconverter
    • IMPORTANT: Make sure you set this value to 0 if not using an upconverter, when used for the first time. Otherwise it might load some random offset from EEPROM.
  11. Scramb - scrambler, distorts the audio so that it is unintelligible to other listeners. If radios use the same setting, they can communicate clearly.
  12. BusyCL - busy channel lockout, blocks radio from transmitting because signal is being received (with BUSY on screen while PTT is pressed)
  13. Compnd - compander (compressor/expander), allows signals with a large dynamic range to be transmitted over facilities that have a smaller dynamic range capability, improves audio quality, both radios should use this option
  14. Demodu - demodulator mode, default is FM, AM/USB can be used for listening only
  15. RxAGC- setting to configure built in AGC which applies to all the modulations. The SLOW and FAST settings might protect radio from freezes caused by reception of strong signals.
    • OFF - completely disables AGC, this might be useful for receiving the most faint signals, with maximum set gain the AGC will not clamp down signal, note: this might cause radio freeze if the received signal is too strong and overloads the radio
    • SLOW - provides wide dynamic range, works really well overall and is the default setting, might be especially useful for HF AM broadcast stations that broadcast music etc.
    • FAST - lower dynamic range, might be useful for short voice communication, aviation, where understanding every word is crucial etc.
  16. ScAdd1 - add channel to scan list 1
  17. ScAdd2 - add channel to scan list 2
  18. ChSave - save current setting to a current memory channel.
  19. ChDele - delete memory channel
  20. ChName - modify memory channel name
  21. ScnRev - scan resume mode
    • CARRIER - resume scan after signal disappears
    • TIMEOUT - resume scan after 5 seconds pause
    • STOP - after receiving a signal, stop the scan
  22. F1Shrt - side button 1 short press function
  23. F1Long - side button 1 long press function
  24. F2Shrt - side button 2 short press function
  25. F2Long - side button 2 long press function
  26. M Long - menu button long press function
  27. KeyLck - auto keypad lock option
  28. TxTOut - max transmission time limit
  29. BatSav - battery save option, the rate between active time and sleep time (OFF/50%/67%/75%/80%)
  30. Mic - microphone sensitivity (+1.1dB .. +15.1dB)

  35. BLMin - minimal backlight brightness, when the screen backlight turns OFF it will go dim to this value
  36. BLMax - maximal backlight brightness, when the screen backlight turns ON it will turn bright to this value. (In Spectrum RX-led stays of on RX when BLMax < 8)
  37. BltTRX - backlight activation on TX or RX
  38. Beep - keypad press beep sound
  39. Roger - roger beep at the end of transmission (OFF/ROGER/MDC1200)

  42. D Live - displays DTMF codes received by radio in the middle of the screen
  43. BatVol - battery voltage and percentage
  44. RxMode - sets how how the upper and lower frequency is used
    • MAIN ONLY - always transmits and listens on the main frequency (NO extra characters on screen)
    • DUAL RX RESPOND - listens to both frequencies, if signal is received on the secondary frequency it locks to it for a couple of seconds so you can respond to the call (DWR on screen)
    • CROSS BAND - always transmits on the MAIN/primary and listens on the secondary frequency (XB on screen)
    • MAIN TX DUAL RX - always transmits on the primary, listens to both (DW on screen)
