[amsat-bb] Mode B operating question...

[Paul Stoetzer]

Always tune the highest of the tune frequencies.

On Mode B, tune your transmitter and maintain a constant downlink and on
Mode J, tune your receiver and maintain a constant uplink.

This keeps you from drifting too far and possibly into QSOs of people using
computer control.

Much to my dismay, some literature, including the most recent edition of
the ARRL Operating Manual still include the outdated suggestion to always
tune your transmitter.
