alanbh@...
 

The answer would be NO. FT8 and FT4 is a tone modulate SSB type signal. You cannot put an SSB or modulated signal through class C amplifier without distorting the signal. The maximum class you can put a modulated of SSB type signal through without or absolute minimal distortion is a class B Amplifier.

I'm running 2.4.0 on my iMac (Big Sur) and my K3S is connected using USB. The K3S appears as two USB Audio CODECs in the Audio MIDI Setup tool - one each for input and output.
I can receive in WSJT-X if I select USB Audio CODEC 2 (the i/p device) but the average level is way too high ( 60db with only noise). Thus it overloads with strong signals.

Unfortunately, the input device has the level controls greyed out in the MIDI control panel, so I can't drop the level there; and of course WSJT-X has no i/p volume control.

Has anybody else experienced this problem? If so, how did you resolve it.
If you didn't, how is your K3S, Mac, WSJT-X audio chain configured?

If you start it with -g it should sync immediately.


Open services and find Network Time Protocol -- stop it and add the -g switch -- then start it back up again and test.

which version of WSJT-X are you using? If it is not WSJT-X v2.5.0 RC3
then can you try that please?

Your rig may require that "Settings->General->Allow Tx frequency changes
while transmitting" is not checked. When using VOX with rigs that don't
accept CAT QSY commands while transmitting you will have to reduce the
VOX hang delay to minimum. It is by far preferable to use a hard wired
PTT, particularly on rigs like yours where you can use either a CAT
command or RTS on the enhanced virtual serial port at zero extra cost.

it is Windows shells like CMD that are picky about path directory separators, the underlying file system accepts both, nothing to do with the Windows kernel.
