[Elecraft] Tracking VFOs

[Bill W5WVO]

I seem to recall some discussion about this a while ago, but can't locate it now -- Is there a way to make the two VFOs track each other by a certain offset? In other words, I set VFO A to 50125.0 and set VFO B to 50125.7, and when I turn the VFO A knob, both VFOs tune, maintaining the 700 Hz offset? If this is not possible with one RX is it possible using the KRX3?
