On the HW-8, a direct conversion transceiver, heath instructed the operator to
tune from the high side down. In other words start at 7.1 and tune lower in
freq, keeping the receiver on the high side of the bandwidth.
that way when a station answered, it would be on the low side, but completely
copyable.
There was a slight offset between tx/rx because heath allowed the VFO to shift
a bit in tx. The actual shift depends on the band
