You bet a loop will help!

See my page at http://w5jgv.com/rxloop for more info.

Here's a snippet from the last line in the article:

"In the background is the shielded loop antenna, which is only 25 feet
away from the vertical transmitting antenna. With this setup, I can
receive on 185.3 KHz while transmitting on 166.5 KHz at 400 watts."

Note that there is only an 18.8 KHz frequency separation between the RX
and TX freqs, and I was running 400 watts on the TX.

A front-end bandpass filter will help also.  Both the loop and the
filter are a good idea.

I'm shortly going to have a similar problem while TXing on 600M and
trying to run the Grabber on the same band!  That should be, as they
say, interesting.
