  Group-
I know this group is not the place for this question so please redirect me:
My BC-348R that I have owned since 1971 is a bit sick.  4 of the bands 
are to low at the low end of the dial.  Not by much but enough to cause 
concern, that a coil or capacitor or both are in need of repair.

I purchased a James Millen GDO to help, resolve possible problems, check 
the coils Q at rated frequency.

The GDO 90651 it self has problems ... cant win.
Symptoms : as you roll the thumb wheel forward to increase frequency the 
needle increases from 0 towards 1 ma
the reverse is true, the needle falls as the thumb wheel decreases 
frequency.  Symptom is the same on all bands, plug in coils.

All caps and resistors  are within tolerance of there published values.  
Voltages are good.

Any Ideas please advise.

Thanks
Hutch
