[ARC5] Need BFO can for BC-946 or R-24 receiver

The 3rd harmonic of 85kc is only 7% away from 239kc (the BFO frequency
in the R-24). If the 85kc can be pulled down enough (perhaps adding a few
pF to the capacitor in the can), you could increase the coupling to
compensate
for the reduced amplitude of 3rd harmonic compared to fundamental.

There are many more 85kc BFO can around than 239kc ones. Worth a try
perhaps.
