[Elecraft] K3 vs. KX3 with wsjt-x

[Brian Waterworth]

It is not disabled automatically in Data A mode.   I have looked and if I
don’t set it purposefully it will remain at the last setting per band.  I
have macros that I use to toggle between voice operation and digital
modes.  I set the mic bias and mic btn menu items accordingly.

Happy to proven wrong as I could then shorten my macros.  But I have
experimented and what I have written is based on my observations of the
menu settings.   Also, I found nothing in the KX3 operation manual to
indicate mic bias or btn are disabled on Data A mode.
