Chasing down interference can be a hassle at times. How are you powering your DB20-G? I know they come with a cigarette lighter adaptor but those can pickup interference from the vehicle pretty easily. The best is to run the power lead from the radio directly to the battery and the ground lead directly to a chassis ground. I usually use ferrite beads on the power leads to the radio and also on ...
Quin and Tom explain how to get rid of RF interference from dimmer switches used to control LED lights. A real story that involves neighbors, the power...
I would want to verify what signal is causing the interference with further scans and tests with a battery operated laptop and portable antenna at other locations as suggested by @wpt in post #11.

Interference in the upper part of the 440 band from Mexico has been an ongoing problem for years. I suggest reaching out to SCRRBA to express your concerns.
I'm looking to "clean up" some noise both in general as well as in some signals. I'm sure I have interference I'm just not sure where to start with it. My first concern is the FM radio band 88-108.

The Federal Communications Commission (FCC or Commission) received a complaint from the Stafford County, Virginia Sheriff’s Office (Sheriff) concerning interference to the Stafford County P25 public safety radio communications system (Stafford County System) operating countywide on certain exclusively licensed radio frequencies. In June 2024, Agents from the Columbia, Maryland Field Office ...
I live about 2.7 miles as the crow flies from an AM BCB transmitter site. They operate at 10kw daytime power and 500w night time power, and I am literally right in their transmitter pattern according to an online radio locator site. I've noticed what I believe to be harmonics up into the...
Myself and several other users have been experiencing intermittent interference on most of the GMRS repeater outputs, especially 462.550. It's also been present on the 462 MHz interstitials. I'm hearing the typical DMR constant "machine gun" noise along with pulses that last for a couple seconds...
Hello all, recently a few family members installed a couple of computer monitors for their gaming setups and now I am receiving interference on the Airbands. I noticed that each monitor will interfere will their own set of freqs, one interferes with some on the commercial/civilian bands and the...
