Hello Again:
Does anyone know if the SCC-4 Crystal
calibrator will fit and can be used in both
the SPR-4 and R-4C receivers? The schematic
in the R-4C manual does refer to the SCC-4
as the one being used. Any comments?

the two filter passbands. But it would seem to me that

You are correct, you can only do one filter at a time. You can use the
