[Elecraft] KX3/fldigi/USB sound card

[Don Wilhelm]

Kenny,

I have heard of that occurring with a KX3 and just a mic - the VFO 
changed with each activation of the mic PTT button.

First, make sure the soundcard cables are fully plugged in (give them a 
good push).  If that does not cure it, continue below.

As an immediate workaround, first change the KX3 menu MIC BTN to OFF, 
and in the control program you are using with Fldigi (Hamlib or RigCat) 
select PTT via CAT command.
I prefer using PTT via CAT command

I believe there may be a firmware change in the making to address the 
problem - but not here yet.  Watch the Firmware Release Notes.

73,
