[ARC5] BC-453B dial calibration (again)

[Waldo Magnuson]

I've had a few suggestions (thanks) and ended up putting a 0.0047 uf capacitor in series with C10A, C10B and the variable C9.  C10A & B should be 690 pf but apparently have grown fatter like people and C9 was not able to bring the dial calibration in at the lower end (210 kHz).  I can now adjust both high (520 kHz with C4E) and low (210 kHz with C9).  
Still puzzling is that my 365 kHz DPY NDB still comes in at 370 on the dial.  I'm beginning to think that must be as good as it gets with my BC-453B.
