How good are you at identifying interference? Not the place for this but I don't know how to contact you otherwise. Have you ever heard this kind of interfere and do you have any idea what could cause this ticking noise? It's consistent, 24/7, and I can't seem to locate the problem. Thanks in advance. kzbin.info/www/bejne/n2PcgZidZd6CrpIfeature=shared Its only on my HF base at 6m and below but not on my UHF/VHF HTs or Mobile Car UHF/VHF base. I ruled out a problem with the HF base station, so its something in the area around it. I do have a HT with some hacked firmware that can receive HF, and its there as well, so its something causing interface on the HF frequencies (all of them!) If anyone has any ideas thank you in advance. I've shut down most of the stuff in the room including the wifi. No dice.
