As has been stated many times, variable speed drives are highly efficient, are quieter, and save a lot of electricity. The old single speed units are being phased out. The byproduct is any variable s

A lot of universal laptop PS go up to 24v and are quiet. I would think your LEDs could get by on a bit less. GL and Happy Holidays. Jim K4QPL Sent from my iPhone _____________________________________

Ive mentioned this before but I have found the Schaffner line filters to be effective for many types of RFI where you can identify the source and prevent the AC supply line from becoming an antenna.

Yeah, the amount of RF emitted is actually very small so long as the device is connected only to a "dummy load". If there is good bonding and RF is blocked at the source with a brute force filter to

True. Maybe widespread spectrum pollution, which is what it really is, should be treated as an environmental problem and not a communications issue alone. And yes, ARRL shouldnt have to carry the ful

Slightly off the Generac topic, taking a circuit off line at the breaker does not ALWAYS identify that circuit as the culprit. Remember house wiring is also an antenna and you might just be separatin

From a ham perspective, if AM is allowed to go away, then fighting RFI will be left mostly to us and without the AM broadcasters, preventing RFI will be considered far less important and our risks in
