[Elecraft] Audio output routing confusion

[Richard Ferch]

You don't hear VFOs, you hear receivers.

When the subRX is off, the only receiver you can hear is the main receiver.
The main receiver's frequency is always controlled by VFO A, so with the
subRX off you are always listening on the VFO A frequency (you can press
and hold the REV button to swap VFOs temporarily and listen on the
frequency that was in VFO B instead, but as soon as you release the REV
button the VFOs are restored).

When the subRX is on, you can hear both receivers simultaneously (depending
on the L-MIX-R configuration setting). With the default A-B setting, the
main RX is in the left channel and the subRX is in the right channel. The
subRX's frequency is controlled by VFO B, except when the subRX is in
Diversity mode, at which times the subRX's frequency is the VFO A frequency
the same as the main RX.

Regardless of the state of the subRX, the transmitter's frequency is
controlled by VFO A when SPLIT is off, and by VFO B when SPLIT is on.

I think you can only hear Main Rec VFO A or VFO B. The only way to hear VFO
A and VFO B at the same time is with KRX3 sub-receiver as VFO B.
