You will need to set the transmit source to "DIGITAL" in menu TX AUDIO Source (or
switch TX Audio Source by long press on M3) if you plan to transmit audio from PC via
USB.

Programs used to receive/transmit CW
Recent firmware got a special support for PC based CW operation if CW mode is
selected on mcHF. Use FT-817 CAT for reading and setting frequencies, in CW modes
you may also use the DTR signal of the CAT serial port (same port!) to send CW from the
PC via mcHF (PTT has to be handled via CAT protocol). DTR Line = High will key the
mcHF. You can use your keyer as well if the PC is not sending CW in the specified mode
(Straight, Iambic A or B, Ultimate). If you enable "Virtual RTS" in the UHSDR menu, RTS
will switch the TRX to TX and DTR will key the CW signal (only in CW mode!). As long as
Virtual RTS is set, the TRX will remain in transmission mode, ready to transmit.
Most programs will be able to send CW using the SSB audio mode. In this case "manual"
keying with a keyer connected to the mcHF is not possible. All CW needs to be
generated as audio signal and send to the mcHF via USB.
•
UCXLog: CW-Mode keying via DTR works (tested).
•
FLDigi: SSB only. QSK keying via audio right channel not supported.
•
N1MM / N1MM+ . You need to enable Virtual RTS in UHSDR menu, and use RTS
for PTT and DTR for keying
Unsupported Programs for CW
Please note,
TR4W
(see discussion
#1174
) does not work with the UHSDR at the time of
writing. It seems to be a bug in TR4W keyer handling. If the situation changes, we
should update this statement :-)
