Uniden 396xt audio choppy on when plugged in

[lucky43113]

My uniden Uniden 396xt sounds great on batteries as soon as I plug it into electric the audio gets very choppy any ideas? It does not do this if I plug the cord into the scanner and not the wall only when power is running through the wall wart.

Is your AC adapter the correct voltage and amperage?

Yes it is made for that scanner

Does it do this when listening to any frequency or just certain ones? AM, FM, Digital?

When you plug in the cable on the AC adapter, the cable becomes part of the antenna system and can cause the antenna to become directional. Try moving the scanner and cable. Which site are you using?

Ohio Marcs Pickaway County

The Pickaway County site shows 2 towers using the same frequencies which is the definition of a simulcast site. Any change in the antenna pattern can make a significant difference when dealing with simulcast distortion. Typical symptoms of simulcast distortion are the scanner showing NFM instead of the control channel frequency, missed transmissions, and garbled audio.

the fix is....don't plug it in ..!
i have 4 handhelds that never get plugged in.
i use an external charger and have extra batteries for them.
i live in Florida, so lightning is of a main concern.
i we still get power problems after Ian.
also check your squelch, it should be at 2.
