You will probably need 2 (or 4) RCA to mono phone plug adapters to isolate one (or two) radios.

Are you talking about this? https://www.ramelectronics.net/RCA-Adapters.aspx

Hi NFR85
What type of cable you need adapters for?
If you want to connect this: https://www.radioshack.com/products/...-loop-isolator
... to your computer/server and scanner, looks like one side already comes with an adapter (female RCA to 3.5mm jack)...
... the other side will require the same adapter here: https://www.showmecables.com/3-5mm-s...SABEgK1evD_BwE

To convert a 3.5mm jack from stereo to mono also get this little adapter: https://www.showmecables.com/3-5mm-s...SABEgJ6hfD_BwE

I spoke to someone who knows about RCA's and I got what I needed. Hopefully it will work. If not it's back to the drawing board. Thank you though for the help

Well the Radio Shack Ground loop came and still have the loud hum. No other hums on the radios I'm using just that 1. Something is not right. Tried putting a newer scanner in with same results. I'm stumped.

Have you tried programming that receiver to the frequency used by an unaffected receiver?

Another question that comes to mind is:
Do you hear the same "hum" if you hook the audio jack from the receiver into another audio card or even with headphones?
I haven't read the entire thread and perhaps you have already gone through this check and if yes, my apologies.

RFI guy might also have a point here.
Is the "hum" perhaps coming from the system you are monitoring? Does it not have a humming sound if received from another scanner?

You have two or more feeds, so program the receiver with the frequency used by one of the other feeds to see if the hum goes away........

You didn't answer the question. It has been suggested to you that the frequency being used is the problem since apparently all other solutions have been exhausted...

I thought that meant try one of the feeds that are working fine and trying using that one. If it isn't what are you suggesting?
