[Elecraft] Virtual second RX

[vidi]

Hi Elecrafters

I need electronics boffins to answer my question:

Do you think it will be possible to feed VFO A audio to left headphone and when switching to VFO B it will be heard in the right headphone??

I do not have the necessary insight to answer that one myself, but was wondering if it could be done.  The reason for wondering about this is: If it was possible, one could have the K3 firmware, VERY rapidly,  push the REV button for you.  That way you will hear VFO A in one ear and B (taking very rapid turns) in the other and when you transmit, the VFO A will be your TX freq. This will be a 'virtual' second RX to easily find the freq of the last station worked in a DX pile up.  I use the 'REV' button extensively to do that.
