[Elecraft] K3 FT8 Levels Sanity Check

[Joseph M. Durnal]

It has been doing well with the settings I posted.  One of the schools of
thought is to use the most gain in the final stage, which should be the
line gain on the K3.

With the KIO3B the levels on the computer, Windows volume & Pwr slider in
WSJT-X should be known quantities.  I suppose, OS & driver versions could
also make a difference.  The last thing I want is a poor quality signal on
the band,

It can be tough when you are operating a temporary portable setup and you
don't have all your regular stuff or locals you know to get a good signal
report.  I just wanted to do some casual operating while I stayed with my
grandmother and prepared for Thanksgiving & FT8 really fit the bill.  Also
doing a little PSK31 here and there, which is pretty much the same
settings.

In a few hours, the mode will switch to CW for the rest of the weekend.  I
hope 20 meters stays as open as it has been!  Running QRP with an end fed
half wave at rooftop height, so, less than ideal, but looking forward to
getting on the air.
