I also have several receive only filters that are suitable for AM broadcast
suppression. Two high pass filters and a band-reject filter. More details

There are at least two other ways of knocking down interference from nearby AM
broadcast stations. Each requires the choice of a particular type of antenna.
The first is to use a balanced tuner of the link-coupled type (the Johnson
Matchbox and Annecke Coupler are the most famous examples)

The BEST way to kill AM broadcast interference coupled via the antenna
is with a high pass

I posted a question concerning an issue with broadcast band interference on
my KX3 and received several good replys. Here's more info on this
issue.there is a local AM broadcast station about 8 miles away but that
is not the one I'm hearing. It's sounding like a Shortwave AM broadcast
from
Somewhere in the back of my head is a recollection of issues surrounding
spurious signals caused by the mixing of strong signals in things like corroded
gutter joints etc. If there is a strong signal present from the AM station at
all times then the other signal varying in strength might cause

While the rusty bolt syndrome is real, what is being discussed here is likely
what is called am broadcast bleed through. This is a consequence of a direct
conversion receiver and as I understand it is second order issue in the
receivers front end, which basically makes it act as a detector to

As an alternative to using RX SHFT, you could try reducing gain in the
RF section if you have the preamp on. Try preamp at the 10dB setting or
preamp off.

All of my antennas are tuned to the band I'm using them on and not just a
random wire type. I tend to see the problem mostly on 30, 20

Check the addresses of your local AM radio broadcasters. You may
have one very close to you and not know it.
Here's a way to find where and who the broadcaster is.
If you have an AM radio in the house compare the signal on the KX3
with those you hear on the AM radio to see if you can identify
decide on what remedies are possible. Just some thoughts,

Check
, if you insert the ATT does the interference go away?? Once you
identify the source you can decide on what remedies are possible. Just
