I havent seen any replies yet. First thing i would do is kill all your breakers and run your rig on battery power. Flip on one breaker at a time to see if its something inside your house causing the issue. Ive heard things recently like counter top ice maker, smart frig, etc. so flip your breakers on one at a time. Rule out something that is under your control. Next maybe its the neighbor’s hvac compressor.. move the radio to the other side of the house, test again. Its going to be a slow process. But it MIGHT BE something within your control. Good Luck, and let us know what you find. 73/chris/AC5CM Typos brought to you by iPhone

This RFI was originally only seen on 17 and 15m but now has extended all the way from 30 thru 10 meters and coming from two directions. They just started in the last month or so. I am requesting the help from someone with a battery powered or mobile radio with a bandscope so that we can locate the sources. I don’t think these noises can be found with a standard AM radio. Rodney from Centerpoint was kind enough to help and indicated that the RFI appears to be coming from an adjacent neighborhood (Brazoswood Estates) but he could not pin down the exact locations. I’m attaching screen captures from my K4D. If they get stripped I can send the in a separate email. K4SCRNCAP0017/18 are approx.. bearing 320 deg. Spacing is ~ 16 KHz KRSCRNCAP0019 is approx. bearing 180 deg. Spacing is also ~ 16 KHz Other times I get spacing between peaks of 45 KHz as in K4SCRNCAP0024 bearing ~310 deg. I’ve noticed sometimes they do drift in frequency, other times they are fixed. If I could arrange with someone with a suitable radio then perhaps we could find the culprits. Not sure what I’ll do if these are emanating from local residences, I’ll have to cross that bridge when I get there (anyone have a good contact with the FCC?). Please contact me off list if you can help or post here if you recognize the waveforms. TIA, 73/161, Allen R.
