Ham Shack Noise

I had a similar problem at my qth in the mountains of CO. The noise covered all bands. Rotated my antenna which pointed the noise source as my neighbors house.  I accused him of growing Mary Jane with grow lights.(They are very dear friends). He said no. Of course when I unplugged the power drill battery charger in my shack, the noise disappeared.  We still laugh about the incident over a glass of wine and I still give him a hard time about his grow lights (he absolutely doesn't have them or grow anything)

Another case in point, I was repairing my very first short wave radio that I have had since I was 13 years old.   When I attempted to use the AM band there were no signals, but a awful buzz.  Since I had just replace the caps and this was a buzz not a hum  I decided to look around the house.  It turned out to be the Food Saver in the kitchen.  The power supply was also the main cause of noise on 80M.  Now I always look at my house first before looking outside the property.

After having it for several years during some noise hunting I found my MFJ 1708SDR switch was putting out a huge amount of hash. I have an email into MFJ to see their opinion. Meanwhile the switch is off line.
