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.
