[Elecraft] K3 BCB reception weak

[n4lq]

Wow. Thanks Scott. That made all the difference!
I have a real problem here with WHAS on 840khz. This is a 50kw station and 
it totally overloads the K3. I use an ICE BCB filter inline with the rig 
just so it can be used on HF. Some rigs are less affected by this station 
but not the K3. What I really need is a series tuned trap for 840khz but I 
guess that would need to be home brewed and installed in the front end.
