[Elecraft] CW activation while in USB mode...

[Don Wilhelm]

Lance,

Getting CW+SSB to work with PTT applied is "on the list", but may be 
some time in coming.

Although it may not help with the current CW+SSB situation, you might 
want to consider starting your sequencer with the K3 KEYOUT and use TX 
INH to hold off RF until the sequencer finishes.  Doing so will allow 
you to begin the sequence with the normal K3 outputs rather than an 
isolated 'start sequencer' signal from a footswitch or a manual switch 
(i.e. normal PTT or VOX to the K3 would start the sequencer, but the K3 
would not tramsmit RF until the sequencer completes).

73,
Don W3FPR
