Hi Guys
Been there, done that... My "boat anchor external receiver" project will
do that... Even with a receiver that's not a boat anchor. As I tap into
the K2's receiver after the low pass TX filter (on J13), listening on
other bands than the K2 is tuned to, is a bit variable and non existent
in some cases. The cost is very low, it's an easy weekend project and
doesn't involve any modifications to the K2 other than fitting a socket
at J13. Options for opto-isolator or relay switching.

Ability to hear DX and pileup simultaneously. That is very good for chasing
window where stations are getting through and you don't miss any chance to
call. With holding "REV" and tuning split TX freq you often miss the point
when DX gives "TU" and starts to listen for next one. I have been thinking
about second K2 to do this. Any experience? How to mute receiving K2 when
transmitting other? That would also permit Single Op Two Radio SO2R
operation in contests.
