[Elecraft] Interesting K3 QRM problem

[Arie Kleingeld PA3A]

Vic,

Cannot really tell what's happening, but I have a suggestion for your BC 
bandfilter.
Connect the filter to the RX ANT in and out connectors, and switch on 
the RX ANT.

Now you can transmit the normal way and use the filter for receive only.
