It has the 'rotor' grounded, which is not good for the AGC, and somestatic when rotating it to tune for best signal. I thought I'd look aroundthe Pearls and the Y2KR3 tech manual for some help, but found only a littlebit there.  So, I thought I'd document what I found on my journey.  It'sattached for your reading pleasure.Let me know what you think.Regards, Larry
