How you alter the frequencies between the VFO A and VFO B is the result
of the button pushing. A>B will make both VFOs the same - the contents
of VFO A are copied into both VFOs. A/B will swap the contents between
A and B. While you hold REV, the contents of A and B are swapped only
until you release the button.
In non-split operation, the A/B button will allow you to rapidly switch
between two different transmit (and receive) frequencies.
When the sub-receiver becomes available, there will also be a special
mode which allows you to 'slave' both VFOs to the main tuning knob. This
will permit true diversity reception, with separate antennas on each
receiver.
I am looking forward to trying this, perhaps with a vertical and
horizontal antenna. Hopefully one signal will get stronger when the
other QSBs!
I don't know what Wayne plans for the audio. In the years of AM,
diversity setups compared AVC (that's what AGC used to be called)
voltages and switched to the best signal. Of course you could listen to
the two antennas in separate ears, but it would be interesting to
somehow combine the audio signals so you would get a (relatively)
QSB-free result.
