[ARC5] BC-453 + Converter

[jsloss]

I'd like to add a small SS crystal controlled 80/40M converter to the rear deck of a BC-453.  Bring somewhat challenged in SS design perhaps you would like to share your favorite circuit.

Also is there a convenient way to incorporate switchable AVC although that may not be necessary as the set will be used only for CW on 80/40 and gain can be controlled w/ the usual RFG pot addition.

Thanks,
