Radio Shack DSP use SCFs?
 

Wonder if Radio Shack 21-543 uses switched capacitor filters as basis.

Google no direct help but does show Rad-Shack parts list that might
be plumbed for an answer.

Would like to move the CW center-freq. around the 750 hz place it's
currently located - per '95 Handbook wherein only a pot's needed with the
MF8CCNs in a design there.

Thnks for the read OMs

PS... now that I've got ur attn, anyone know a 'filter' that hunts
out a hetrodyne freq. and nulls it automatically?
