[K3] "SSB +CW" vs PTT

[Iain MacDonnell - N6ML-2]

I seem to have encountered a conflict between "SSB +CW" (i.e. CW
whilst in SSB mode - useful sometimes on 6m) and PTT. I have my K1EL
WinKeyer configured to assert PTT during CW. It seems that CW in SSB
mode is "muted" when PTT is asserted, so I get a short "blip", then
stay in TX, but no CW tone. Perhaps PTT causes the source of audio to
be "moved" to "MIC-SEL" instead of the CW tone, as opposed to a mix of
the two? Bug or feature? Fixable?

Feature ... PTT puts the K3 in transmit using the selected mode
(e.g., USB).  The CW input puts the K3 in transmit using CW.
That's why CW VOX (QSK or semi break-in) needs to be forced if
SSB+CW is enabled.

Unfortunately, the K3 lacks independent front and rear (mic vs.
ACC) PTT inputs so there is no way to differentiate the source
of the PTT.

Not only that, but I'd have to reconfigure my WinKeyer to not assert
PTT each time, which is more hassle than it's worth... shame...

It wouldn't help in my case anyway - WinKeyer and footswitch PTT are
"Y-ed" together on the read panel input.
