[R-390] Measuring sensitivity

[Joel Richey]

Interesting thread, here's how I do it, don't need a bunch of antique signal gens or voltage dividers, I just turn on the old 390A let it heat soak for a half hour of so, go the band I wanna listen to, connect the antenna and if the noise level comes up (which it always does) then I know I have all the sinsitivity I can use.

Hope I didn't step on anyone toes, but sometimes I think we get so far n woods we can't  see the trees.

Joel Richey W2DBO said that and I think my 390A and hear anything yours can and maybe better???
