Mark:

I have NEVER owned such a loop, and frankly, can't comment on its exact
workings.

However, the others seem to be suggesting, switch radio and loop to battery
power. Is the noise gone? If so, you have localized your problem. If not...

Shut off everything in the home (building, business, etc), is the noise gone?

If so, turn on things one at a time and locate the interference.

Frankly, I suspect I am wasting my text here, and you have already done this...

Hello,

I got my Icom IC-R75 rx. connected to a Wellbrook ALA1530 loop antenna.
On this antenna, I have an enormous amount of 'buzzz' on much MW and SW
frequencies. It is much less noticeable on a portable receiver with a
whip antenna.
When I have just the center pin of the PL259 plug connected to the
receiver, much of the buzz disappears. As soon as I connect the other
part of the plug too (the shield of the coax, so to say), it becomes
audible again.
I am not very techinal, and don't know where to start troubleshooting.
Should I look for damage on the coax cable? Could it be badly
soldered/connected BNC plugs? Anything else that's worth investigating?

Many thanks for any tips!
