Thanks, Joe. I knew there was some logical explanation. I did do a
search of previous posts before I asked my question and I didn't find
any post that was the direct answer I needed.

Therefore, at this juncture, the K3 is totally not up to the job when
it comes to broadcast band DX hunting. What's up here?
As documented here literally dozens of times, the TR switch contains a
high-pass filter with a 1600 KHz cutoff to protect the PIN diodes and
keep them from generating interference due to strong broadcast band
signals. If you want to receive the broadcast (and MW bands) with full
sensitivity, 1) install the BPF3 receive filter *and* 2) use a separate
receive antenna connected to either the RX ANT IN jack or the XVTR IN
jack.

some of you know the story. ;-) At any rate, I have the general
coverage module installed in the main receiver, but I have found the
sensitivity of it in the broadcast band to be horrible. I can hook up
my Palstar R40 and get a 40 over signal from a station, but with the K3
hooked up to the same antenna that station is an S4 -- just barely
over the noise level. This is a station 100 miles way that I could
receive on that old GE transistor radio at what would have at least been
an S9 signal. Therefore, at this juncture, the K3 is totally not up to
