When you enable the different frequency transceiver function, KN920 will
automatically PTT / CW reception and transmission control switching frequency.
When the current job in the VFO-A, press the PTT / CW, KN920 will automatically
switch to VFO-B transmitter;
When the current job in the VFO-B, press the PTT / CW, KN920 will automatically
switch to VFO-A emission;
When the current in the VFO-A launch, release PTT / CW, KN920 will
automatically switch to VFO-B receiver;
When the current in the VFO-B launch, release PTT / CW, KN920 will
automatically switch to VFO-A receiver;
Note:
As KN920 launch low-pass is to use relay control, so I do not recommend that
users use two different bands on different frequency transceiver functions.
When using automatic key feature when working different frequency if needed,
please confirm the two VFO mode of operation is CW.
