You probably could benefit from a BC band reject filter. I bought
one a few years ago anticipating station on 550-KHz in Anchorage
might inpack my 600m Rx on 510-KHz. I bought the Clifton Labs Z10020
Medium Wave Broadcast Band Reject Filter (540-1700 KHz).

I forget the exact price but think it was in the $60-70
neighborhood. Rejection is something like 60-80 dB.
I did see an improvement it the receive noise floor below about 520-KHz
Connect to the KXV3 xvt-Rx BNC jack. Use of the K3 on 630m requires
a KXV3 as you transmit in the TEST mode at 1mw thru the KXV3 xvt-Tx
BNC. This is good as you will need to drive a PA which will not pass
received signals. An external coax TR relay is needed after the PA
to bypass RF to the xvt-Rx port.

Considering that all I hear down there is broadcast station birdies, I'm
guessing you're right. :-(
