In SO2V mode, the key changes the RX focus to the Sub receiver and enables the Sub audio if necessary (Orion). To use this feature
set the CQ repeat time a little longer than normal and start a repeating CQ using VFOA (Main). If nobody answers, press the key to enable the Sub receiver and tune the band. Pressing again will change the RX focus back to VFOA and turn off the Sub if Config > Dual Rx Always On is not checked. With Icom radios that only have one VFO knob,pressing the key also changes the knob association to the Sub VFO.
If you do not find someone to call before the CQ timer expires, the program will call CQ again on VFOA. If you type a character into the
VFOB (Sub) Entry window or press a function key, it will cancel the repeating CQ running on VFOA.
The TX focus will automatically shift to the proper VFO prior to transmitting when you call someone. Some radios switch faster because they require fewer configuration commands. If you call someone with the VFOB (Sub) Entry window and decide that the CQ repeat needs to start again on VFOA, press CTRL+CQ-Key. The program default for the CQ-key is F1 and this is set in Configurer >Function Keys tab.
If someone answers your CQ while the RX focus is on VFOB (Sub), press the key to change the RX focus prior to entering the callsign.
In the case of the K3 transceiver, there is special functionality associated with the Ctrl+Alt+D and Grave accent keystrokes. See the K3 section under Supported Radios. - A single receiver K3 can be used in SO1V or SO2R mode. A dual receiver K3 can be used in all program modes, including SO2V
- ALT+F12 toggles Sub on and off. It is identical to pressing the SUB radio button. To leave SUB on all the time, select Configurer>Dual RX always on
- If you have selected Diversity mode on the radio, toggling Sub off and on via Alt+F12 will turn Diversity mode off
- Logger preserves diversity reception on the K3 unless RX Focus changes to vfoB at which time the subrx will switch to vfoB
- K3 Subrx ON/OFF control by Logger
- Independent of the state of Dual RX Always On:
- changing RX Focus to vfoB turns the subrx ON
- Ctrl+Shift+Up/Dn does not change the state of the subrx
- Alt+F12 toggles subrx ON/OFF if RX Focus is on vfoA (action disabled if RX Focus on vfoB)
- Dual RX Always On checked:
- clicking any vfo bandmap/avail. window spot or Ctrl+Up/Dn turns the subrx ON
- changing RX Focus turns the subrx ON
- if dual rx always on was unchecked and the user checks it, subrx is turned ON
- Dual RX Always On unchecked:
- If the TX & RX Focus is on VFOB and the RX Focus changes to VFOA ( keystroke), the subrx stays ON
- If the TX & RX Focus is initially on VFOB and then RX & TX Focus is on VFOA (PAUSE, CTRL+Left or vfoA Bandmap/Available window spot click ), the subrx is turned OFF
- if dual rx always on was checked and the user unchecks it, subrx is turned OFF
- Ctrl+Alt+D command action:
- If "Dual RX always on" is ON and the Sub RX is ON, turn "Dual RX Always On" to OFF and leave the Sub RX ON
- If "Dual RX always on" is ON and the Sub RX is OFF, turn "Dual RX Always On" to OFF and leave the Sub RX OFF
- If "Dual RX always on" is OFF and the Sub RX is ON, turn "Dual RX Always On" to ON and leave the Sub RX ON
- If "Dual RX always on" is OFF and the Sub RX is OFF, turn both ON
- Stereo (grave accent) command action:
- If the subrx is OFF - check "Dual RX always on" and turn the subrx ON
- If the subrx is ON - uncheck "Dual RX always on" and turn the subrx OFF unless RX Focus is on vfoB
- Digital radio modes FSK D, AFSK A and DATA A are supported
- FSK D, AFSK A and DATA A are displayed in N1MM as RTTY, AFSK and PSK respectively
- PSK D is not supported by N1MM
- Adjust audio levels in AFSK A and DATA A to give 4-5 bars on the K3's ALC meter. This allows the K3's firmware ALC to control power without clipping peaks and causing IMD. In PSK31 and other digital modes requiring high linearity, keep the requested power setting below 60 watts (AFSK RTTY can be safely used at 100 watts)
- RIT control - When in RUN mode, the Up/Dn arrow keys change the RIT frequency (if the K3's RIT is turned on). When in S&P mode the radio frequency is changed
- Using the program as a voice keyer with a K3 on SSB:
- Option 1
- Connect your microphone to the mic input of the sound card and the Line Out of the sound card to the Line In on the back of the K3
- Set soundcard program to drive Line In
- Select LINE IN with MENU:MIC SEL
- Command Tx (or PTT or...) and adjust the MIC GAIN (which is now LINE IN gain) for proper audio level
- Option 2
- Connect microphone to desired microphone connection on the K3
- Select MIC with MENU:MIC SEL
- PTT and set Mic Gain
- Connect sound card as described under Option 1
- Now, if you set MIC+LINE ON then both audio sources will drive the K3. The MIC GAIN control will control the MIC GAIN only. LINE IN GAIN must be set when LINE IN is the selected source via MENU:MIC SEL
- The K3 can accept PTT switching from several sources, including: a keying circuit from a serial or parallel port to the K3's PTT IN; PTT from a Winkeyer; RTS (pin 7) on the radio control port; or using "Radio PTT via command"
- Do NOT use multiple methods of PTT control in parallel; in some cases doing so can leave the K3 stuck in transmit at the end of function-key messages. In particular, do NOT check "Radio PTT via command" if you are using RTS on the radio control port, or any other hardware PTT connection, to control PTT. Using "Radio PTT via command" together with hardware PTT control can cause the K3 to get hung up in transmit, so don't do it!
- Procedure for configuring RTS on the radio control port: Start with the K3's CONFIG:PTT-KEY set to OFF-OFF; configure N1MM to control PTT from RTS on the radio control port (Port setup); set the K3's CONFIG:PTT-KEY to RTS-OFF
- Warning: leaving RTS set to Always on with the K3's CONFIG:PTT-KEY set to RTS-OFF or RTS-DTR will cause the K3 to be permanently in transmit
- The K3 accepts CW keying on DTR (pin 4) of the same COM port you're using to control the K3. This method can be used when other methods (e.g. Winkeyer or a keying circuit on a separate COM or LPT port) are not available
- CW and radio control on the same COM port do NOT work in SO2R mode
- CW on DTR does NOT work with some USB-to-serial adapters (e.g. Prolific chipset)
- CW on DTR may be missing some capabilities and may have other undesired side effects - use at your own risk
- Procedure: Start with the K3's CONFIG:PTT-KEY set to OFF-OFF; check the CW/Other box beside the radio control port in the Configurer and configure N1MM to use DTR for CW on that port; set the K3's CONFIG:PTT-KEY to OFF-DTR
- Warning: leaving DTR set to Always on with the K3's CONFIG:PTT-KEY set to OFF-DTR or RTS-DTR will cause a permanent "key-down" condition
