1. [RFI] RV converter noise (score: 1): Author: Jim Netwal via RFI <rfi@contesting.com>; Date: Tue, 26 May 2020 13:36:51 -0500; Does anybody know of a RV converter that is not noisy? I have noisy spikes ever 50 kHz. Can I put toroids on the power leads? Thanks, Jim W9UUM _______________________________________________ RFI mai; /archives//html/RFI/2020-05/msg00110.html (6,558 bytes)

There's an AC line filter on page 23 of k9yc.com/RFI-Ham.pdf You can also use my latest (2018) Cookbook for transmitting chokes wound with #12 TH; /archives//html/RFI/2020-05/msg00111.html (7,943 bytes)

Re: [RFI] RV converter noise (score: 1): Author: Jim Brown <jim@audiosystemsgroup.com>; Date: Tue, 26 May 2020 12:37:45 -0700; I meant to add that there's no guarantee chokes on both power leads will solve your problem, but it's the best starting point. If you notice some reduction of noise, use multiple chokes in series. 73; /archives//html/RFI/2020-05/msg00112.html (7,516 bytes)

Re: [RFI] RV converter noise (score: 1): Author: David Eckhardt <davearea51a@gmail.com>; Date: Tue, 26 May 2020 15:32:55 -0600; I do not know what your power requirements are and would assume a 12 vdc to 120 vac / 60-Hz inverter. However, I use a 300-watt inverter (for small loads). It is a GoPower Model GPSW-300 and is spiff; /archives//html/RFI/2020-05/msg00113.html (7,712 bytes)

Re: [RFI] RV converter noise (score: 1): Author: K9MA <k9ma@sdellington.us>; Date: Tue, 26 May 2020 18:32:57 -0500; Converter in the RV world is either a 120 VAC to 12 V power supply or a battery charger. Of course, they can produce the same kind of RFI as an inverter. 73, Scott K9MA -- Scott Ellington -- via iPad; /archives//html/RFI/2020-05/msg00114.html (8,108 bytes)

I use a Samlex SEC-1250UL converter after the original POS Winnebago installed let the smoke out. I have never heard noise/birdies on HF from it when using dipoles o; /archives//html/RFI/2020-05/msg00122.html (8,446 bytes)
