[Elecraft] FT8

[Don Wilhelm]

Mike,

The same COM port can be used for both control and PTT.  You must set 
the K3 KEY-PTT menu to the correct setting (depends on the PTT setting 
you have chosen in your software application.  If the red TX indicator 
does not turn on, you have not set it correctly.

OTOH, using PTT via CAT command works reliably (with PTT-KEY set to 
OFF-OFF), and I recommend that.  Alternately, VOX works reliably in DATA 
modes, so that is a good second alternative.

If the TX LED turns on, the K3/K3S/KX3/KX2 is in transmit mode (so no 
problem with that), but if you do not get proper transmit, check the 
audio levels as I indicated in the last 2 emails I have sent on this 
subject.

Two different problems - 1) failure to turn on transmit (PTT problem) 
and 2) Insufficient (or excessive) audio from the soundcard.  Each one 
has its separate indicators.

73,
Don W3FPR
