Why Your Ham Radio Gets Noisy Every Evening

My ham radio can sound perfectly clear in the afternoon, then become buried under a harsh, continuous buzz after dinner. In this video, I show how I use that predictable timing to determine whether the noise comes from propagation, my own equipment, a household device, or an external source. I cover how I: • Create a repeatable test setup and track noise patterns • Compare local interference with normal evening propagation changes • Use a portable receiver to locate possible sources • Check household devices, shack connections, and nearby interference • Match ferrites, filters, repairs, and receiver controls to the actual cause • Record reliable evidence before taking action My goal is to diagnose the cause methodically instead of replacing antennas or adding suppression at random. 0:00 Why evening noise appears 1:21 Create a repeatable setup 2:14 Track the noise pattern 3:48 Propagation or local interference 5:06 Test with a portable receiver 7:07 Check household devices 9:09 Test shack connections 12:30 Investigate external sources carefully 13:46 Match remedies to causes 15:44 Use receiver controls wisely 18:02 Make reliable comparisons 18:57 Turn evidence into action #HamRadio #AmateurRadio #RFI #RadioInterference #Shortwave #RadioTroubleshooting
