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 _____________________________________
Interesting story Don! Id start with the easy stuff first. Toroids on the speaker lines, toroids or a brute force filter on the AC line. If youre a quarter mile away just doing that should drop it to
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.
To avoid is not good economic or ecological advice. We have had a Carrier Infinity VS system for three years now. No RFI, it has saved hundreds of dollars in electricity, is quiet in the house and gi
Scott has handled this in a very strong, proactive but cooperative manner. As energy saving and alternative energy generating devices become the norm for modern life, finding ways to embrace the tech
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
I think we can all be a bit more constructive on this reflector and stay on point to solve the problems ourselves. Get out on the Interstate and check out the number of serious speeders. How many cop
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
Thats true Dan. Its a pity that some people get satisfaction from disparaging comments and putting other people down. We also hear this kind of stuff on the air which is even worse as one never knows
Dave, Honor is being willing to write your last email. Thanks on behalf of not only myself but others in our group who contest or use the digital modes. There are a lot of facets of ham radio I dont
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
I have a Carrier "Infinity" system with fully VS drives on both the compressor and air handler fan. It's their top of the line most efficient system. Never heard a peep of RFI from it. I'll walk clos
Yes! Power company here has started putting solar panels on the roof of their plant which was previously all diesel. About a mile from us. Much more noise than before. Fortunately they are south and
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
Can we not stick to our own science and get off the cant trust anyone but xxxx soapboxes? If polluters can be verified, call them out. What about. never solves anything. Other than the cool light sho
Thanks! This has to be the funniest scam I have seen. Didnt realize good ole Nikola Tesla was still around. But with all that dirty electricity sloshing around my shack Im sure it might take more tha
Dont forget about the capacitor which they mention, Pete. How can you clean a dirty sine wave without one? Jim Sent from my iPhone _______________________________________________ RFI mailing list RFI
This reminds me of that old scam where the traveling repairman would discover gutter leaks at a farmhouse and repair them in place with his welder. Depending on the negotiated price he would finish t
I think if we had a list moderator this pseudo political thread would have been halted long before now. Give it a break, guys. Jim K4QPL Sent from my iPhone __________________________________________
