Power Line Adapter noise interference
oh dear, I use this model....
About 3 weeks ago our neighbour installed power line adapters. The PLAs in question were branded TP-Link [....]
How did I know that my neighbour had installed these? Well, the 50MHz band was immediately submerged under a wall of radio noise. Much tinkering with the Noise Blanker settings on the Icom IC-7300 allowed me to separate out two distinct types of noise - 1st a sound like a chicken clucking which was there 24 hours per day and - 2nd a wideband swoosh of white noise of varying strength which happened at certain times.
