Also, does anyone know of any RFI problems within certain bands for this supply? I have a VS-35M which is the variable-voltage version of your RS-35M and I've used it to power rigs from 160 thru 2M and have never had an RFI problem either way. Very quiet P/S. I also have an SS-30 switcher and it's just as quiet as the analog supply. Astron "makes good stuff". I agree...I've had this one almost 15 years now, and it's been great. I did take a power spike in 95 from a lightning storm and had to ship it then. As I remember then it was about $65 to fix it, and I forgot what my out-going shipping is...The cheapest I can find right now is $40...For that much plus what I am sure is an increase in repair fees at Antron, I'd almost be better off going for a new supply. K0HB said: I have 2 RS35M and one RS50M in the shack, between them often loaded to about 80A in aggregate. I have no known RFI problems from them. (Sorry, no schematic) UNQUOTE Thanks anyhow, Hans...This unit had sat unused for almost 2 years, and I didn't know whether to consider the failure during tune-up to be due to that, or the fact I was on a band I hadn't used before. I had made 1 QSO with Jim, N2EY on 30M a week ago and had no problems then... The CH53A and D Sea Stallion's used to have a problem losing the primary AC generators if the HF was tuned up on 7 or 13MHZ due to RFI problems in the overspeed protection system. Hopefully someone else can come up with the schematic for me...I've got several feelers out. 73 Steve, K4YZ |
