Hunter,
My instinct would be to remove and re-seat that
board. That could solve the problem. A defect in
the board is unlikely.
All this assumes you have the correct mode in your
K3 (e.g., not listening to BC band in CW mode).

I have the General Coverage Module in my K3, serial number 6969. Recently,
whenever I listen to the broadcast band, the signals will drop out, or
significantly down and an occasion audio will distort. I do not notice this in
any other mode, or on the ham bands. Any thoughts?

I am not talking about the need to desense because of an IF frequency but
that the front end ham band filters may still be active when doing SWL. It
is my understanding that the K2 can receive SWL but its front end filters
are ham band only so if you are between any ham bands the sensitivity

Hi Joe,
Yes, you can add general coverage receive filters to the main receiver
and/or the subreceiver. This is the KBP3 option (see order form). The
rig automatically selects the narrow ham-band filters when you're in
the ham bands, and the wider filters when you're in-between ham bands.
This is distantly related to the mainstream of QA on this net.I intend to use
my new K2 to drive a Icom IC-2KL amplifier. Please imagine for now, there is an
intermediate amp between the K2 and the 2KL.

Why would you need a tuner between the K2 and the XV-50? The XV-50 has an
input attenuator that provides a good 50 ohm load, and the K2 should drive
it just fine with only a piece of coax connected between the K2 and XV-50 -
the SWR on that coax line should be very close to 1:1.
