[Elecraft] [K3] clarification on VFO and 2nd Rx

[Bob Cunnings]

For years here at my place of employment we've offered UHF diversity
receivers where, instead of  switching between the two signals, we
blend the audio outputs of the receivers in a ratio controlled by the
RF level of the received signals in the two receiver sections. Once
done using analog circuitry, we do it in the digital domain these
days. We refer to it as "ratio combining diversity".
