[R-390] Zero adjust on R-390 receiver

[Bob Young]

Is there an adjustment in there? Mine needs about a half a turn to separate the surfaces but it gets difficult to turn once it gets to the point where the surfaces start to separate, these is some drag also and I have to turn it back and forth a few times to get it to stop turning the whole mechanism. I have it adjusted so it can't go in more than half a turn, if I turn it in anymore than that I feel like I'm forcing it and it creates drag (bending something?) when tuning from about 400 to approx 300 but only when tuning down,
