Hi all, I would like to find a power supply to power the K3s that is completely silent. I've owned an Astron RS-35M, which was great until it started buzzing like crazy. I swapped that out for a Samlex SEC-1235M, and did the fan mod to keep the fan on constantly at low speed. The problem here is that when I'm running FT8 or RTTY for more than about a half hour, the fan goes into high speed and stays there for an hour or more, long after the rig and amp's fans have shut off. And because it's a tiny fan moving a lot of air, it's incredibly loud.
I'm looking for an RF-clean power supply (either linear or switching) that can deliver 25A continuously without requiring a cooling fan of any kind. All it's running is the K3s/P3 and a couple of boxes with less than 1A draw each. The front panel meter on the Samlex is showing a tad over 20A when transmitting 100W in FT8/RTTY. Any suggestions? Within reason, cost isn't a major issue. --------------------------------------------- 73 and Good DX Peter, W2IRT ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
