[Elecraft] K3: CW in SSB mode broken?

[Edward R. Cole]

Lance and Don,

That is exactly how I have my K3 configured with an external 
sequencer.  In voice the PTT keys the K3 and I take KEYOUT to key the 
sequencer.  The final stage of the sequencer defeats the INHIBIT line 
to the K3 enabling transmit.  I do not run QSK on VHF so I manually 
switch the sequencer for hand sent CW.

Of course if under sw control of WSJT (JT65) PTT is controlled via 
RTS or DTR lines in the serial interface and the radio is in DATA-A 
which uses USB.  JT65 has a CW mode, although I have not used 
it.  Instead I have a separate CW program that keys PTT and CW via 
the RS232 line.  I only use keyboard CW when running eme.

I use BAND0 line to enable my inhibit so it is not in use on 
HF/6m.  I will add 6m sequencing/inhibit via DIGOUT1.  I just 
installed a 222 transverter so I will also need to use BAND1 for 
TRN2.  Simple diode steering will enable all these to enable the 
inhibit function:
