[Elecraft] Second RX

[Dave]

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.
