[R-390] Cam alignment

[Paul Roche]

I am sure I am wording my question incorrectly! I thought I remember reading somewhere that when turning the MHZ dial it should be maybe 1/4 turn until it hits the first detent at 0.000 MHz I was just wondering if I don’t set it in the detent at 7.000+ would I still have some range a little above and a little below the ends of the bands. As I said, I’m probably not making it clear,

>> I am trying to align my cams to exactly 7.000+ MHZ and I have a question about the planetary gear with that spring. I thought I read I should install it with the detents halfway between the spring position. But if I do that, now when it hits the detent, it is not 7.00+ anymore.
>> When I’m putting this together, should I install that planetary gear with a detent engaged at the 7.000+? I hope this makes sense.
