[600MRG] Experiencing a wierd BCB interference recently

[Paul Signorelli]

Hi Andy.

Any nearby diode rectification can cause cross modulation.

The closer you are to the BC station the worse it can be.

It can be caused by a dissimilar metal contact, a guy wire to tower connection, etc.

The dissimilar metal becomes a diode which reradiates the BC station.

My PRC319 (military backpack radio)  has input protection diodes on the front end to prevent over load,

when I attach a long wire to it, it does a great job of

reradiating the BC band. It causes BC noise on all my other LF radios.

Any long wire with a diode at the end will do it.

A power line can do it.

You should be able to DF it with a small transistor BC radio.

If you find a suspect connection just clean the wires/connection really good and add a clean jumper.

This is could be a Sherlock investigation.
