I have RFI on 80, 40 and 30M each night from sunset to sunrise every day. Can I send a video of my IC-7300 panadapter as evidence? It's ONLY from sunset to sunrise. I’ll try to describe it…the signal is every 100 Hz, the frequency varies in what appears to be a sin fx or sawtooth over about 50 Hz…it’s periodicity is 2 Hz. So, on the waterfall, there are multiple zigzag patterns that repeat every 100 Hz. It begins to diminish a bit above 8 8 KHz and below 6.7 KHz. It’s still there on 80M and 30M but much less intense. Any help appreciated. 73. John AB8O |

These days the only practical way to identify most RFI sources is to first locate it first. There are just too many electronic and electrical devices to put together a database of noises. http://www.arrl.org/radio-frequency-interference-rfi Zak Lau W1VT ARRL Senior Lab Engineer |
