In the Army they taught us to turn on the spot signal and tune the spot against
the received signal.  When you hear the warbling stop, you are zero beat on the
RX signal.

The warbling I'm speaking of will fewer beats per second as you get closer to
the RX frequency.  When the two frequencies are matched there will be no warble.
Sometimes with digital VFOs you can't get an exact match, but you should be able
to get it within one or 2 Hz.

Tuning for zero beat is the same method orchestras use to match the Concert
Masters note at the beginning of a concert, so it is very accurate.  It is also
the way piano tuners tune pianos with a tuning fork.

Yep, it will be more meaningful soon.

What a wonderful place to live.  I've never been there, but know it must be
beautiful.

Essential Liberty to

Safety deserve neither 
Liberty nor Safety"
