Wow, this could be what my problem has been. In my past years as a microwave engineer, I used many of the MMIC amps when they first came out and they were difficult to tame, as they have a ton of gain at very low frequencies (lower than what they were intended to be used). I can see this may be what my problem is (was), as the signal that was creeping across the screen was large in amplitude and shaking a bunch....(aka like an oscillation). It looks like Elecraft has noted the problem. I may have temporarily solved my problem buy "finger tweaking" the assemblies by pushing, pressing, etc. but a more permanent solution will be needed eventually. ----- Roger W5RDW -- View this message in context: http://elecraft.365791.n2.nabble.com/P3-SVGA-interference-tp7556731p7556751.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ 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
