That's good advice, and no, I don't truly need 35 amps. I was just going that route to give myself a little breathing room. It's good to hear that it doesn't use a fan. That's one less thing to worry about. It looks like I'm gonna go with the RS-35M based on everyone's advise. I plan on using it at home so the extra weight is no problem, and really, at 27 pounds, it doesn't seem that bad. The low noise is the main thing, because even if many switchers are designed for low noise in the ham bands, I also wanna use it for SWL'ing, CB, and AM broadcast. HRO should be hearing from me shortly.
