So for the longest time I thought that the Boulder BrandMeister repeater had a problem because I was seeing full-strength unmodulated-FM-carrier style interference on the output frequency of 445.050 MHz. But I did a little foxhunting ๐ŸฆŠ and determined the noise was coming from … inside my house. ๐Ÿ  Spooky!โ€‹ ๐Ÿ‘ป

With some primitive directional radio finding techniques ๐Ÿ“ป, I determined which half of the house I thought it was coming from and then I started unplugging/turning off electronics. Lo and behold our LED HDTV ๐Ÿ“บ was causing the noise! And it wasn’t particularly broad-spectrum: ยฑ25KHz from the frequency and the noise was gone.

Unlucky, I guess? Or the other thing? I don’t know. But I do know that if we want to use that repeater from our house, we’re going to have to turn off the TV first. ๐Ÿ˜›
