Getting rid of humming noise on BCT15X scanner

[xms3200]

I have a Uniden BCT15X scanner which I use for VHF air and is awesome, however, when there are no transmissions on VHF, I get this constant humming sound due to the scanner being plugged into the ac outlet. Is there a way to get rid of this alternating current humming sound.

Thanks for all replies in advance.

Try a different power supply, the wall wart is probably about ready to take a crap.

I use my HF radio power supply, power poles and all to a 3 pole connector on my BCT15 scanner. It does a very good job filtering out the hums and other static.

If using an external amplified speaker, you need a ground loop isolator between the scanner and the speaker.

Actually, I am using my headphones. Are there some power supplies that have less hum or do a good job of filtering the hum…just wondering.

Okay, I figured it out…it only hums while scanning, if I stop scanning and listen to one freq., there is no humming at all.

Samlex 1212 power supply. Much better than a wall wart.

I see it has a positive and neg terminal at the back. How do you adapt this to the plug at the back of the Uniden scanner.

Use the automotive harness that came with the scanner. Just use red and black wires.
