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.

Steve: The K3's PIN diode T/R switch displays quite a bit of attenuation
in
the broadcast band, especially below about 1 MHz (I've measured 18 dB
attenuation at 500 kHz).
The only solution I'm aware of is to install the KXV3. With the external
antenna input provided on this interface (which bypasses the PIN diode T/R
switch) the K3 is an excellent performer on the BCB.

Is sensitivity very low below about 1000khz in the BC band or is it just
me?
It really drops off there and I can only pick up a couple of really strong
stations below that. I did install the KBF3. Does that attenuate the BC
band?
I did make sure the ATU was in bypass.
