Welcome Millard! Glad to hear that it sounds like UPB isn't "dying on the vine" afterall - I wrote the article in my signature about implementing SA UPB - I would love to see some new devices - top of my list is a ceiling fan control. Otherwise, I've found tremendous flexibility in the product line.
I'm curious - what's the best way to test if a device is causing noise? I'm even OK with buying or borrowing some reasonable test equipment for the purpose; I have some EMI filters I get pretty affordably and they're very compact - I'd like a way to verify if they're doing the trick (I could send one to you guys too if that'd help) - and I'd love to be able to test inline between a strip and the outlet to see if there's a lot of noise or signal sucking going on.
