[R-390] Re: Crystal Oscillator Coil Adjustment

[Gord Hayward]

When I ehabilitated my R390A I asked the same question.  The advice 
(good) was that
because the resonance depends on both L and C, if all the trimmer caps 
give a peak not
at the end of their ranges the coil is set right.  If one cap hits the 
end before it peaks, then
adjust the coil a bit and realign ALL the others again.

Cheers, Gord (VE3EOS)
