When Good Advice is True
The links supplied by Druid Hills Radio are very important to know for the indoor transmitter operator who is bedeviled by sticky hum.
The worst I ever had was a Ramsey AM-30B but was quickly solved when the technician at Ramsey admitted that the supplied power supply was the cause. Using a better power supply made the problem go away.
All of my SSTran transmitters, AMT3000 and AMT5000, have been hum free with no difficulties, but I read that some other users have had hum experiences.
The homemade and indoor-tested Big Talker Shortwave Transmitter at 13.560 MHz was hummy on indoor radios yet outdoors was clean as whisper.
The guy on the video talks about "the mains", and that is another way of saying "power lines".

I find that most of my problems come over the air, but for problems coming from your home's power lines this might be useful: www.ebay.com/itm/W-3900-Audio-Noise-Power-Filter-Power-Conditioner-Power-Purifier-with-US-Outlet-/131532380731?hash=item1e9ff0da3b:g:6AQAAOSwi0RXxT--I purchased one 2 years ago to help with AM-BCB and SW DX reception problems at my Michigan home. It's amazing how different were conditions between my home in SE MI and my home in SE PA.
