Well, the mysterious QRM is back, and I think it's from grow light ballasts. It seems to match what I've read
It's all just a guess until you track it down. You're rationalizing giving up by coming up with a conclusion without any evidence.
Who else is suffering from a grow house, and what are you doing?
Every time I tracked down interference it wasn't from a grow house. Until you track it down, you won't know either.
So is this the interference on 40M you mentioned in an earlier thread or something different? In general, something really strong is usually also really easy to find.
Yes, this is the same interference, as far as I can tell. The noise acts like it's on a timer, and will suddenly switch on or off. That's why I was thinking of a grow house.
I live in a designated flood plain in California and the area was determined to be off limits to ANY permitted work on the houses until the levees were upgraded. So you know how ridiculous it has gotten, one family suffered a fire that damaged their house. The feds said they were forbidden from fixing the damaged house.
Instead, they were commanded to raze the burned house, build a platform 25 FEET high, and build an entirely NEW house on top of the platform. 25 feet is the maximum potential floodwater depth according to FEMA. The cost was more than a good condition house in the area was going for. The family simply had to walk away from their mortgage.
No roof replacements, no plumbing work, ANYTHING that required permitting was made illegal unless the house needing work was razed, a platform built above maximum flood level, and a new house built on the platform. Now that the levees have been "fixed", FEMA has refused to lift the restrictions. There are lots of houses here that people have simply walked away from. The area is perfect for grow houses and other illegal house uses.
In addition, there is a new law here that states that police will only pursue violent crimes (murder, rape, that sort of thing). It was the answer to an overcrowded prison system. So, we have carte blanche for crooks to do pretty much whatever they want.
