The decoder is presently hardwired to decode signals within +/-110 Hz (or +/- 150 Hz with the -w option) of 1.5 kHz. Since the decoder can read either .wav or .c2 files, it seems to me that Mike’s request could be handled either in wsjtx (by changing the center frequency used to derive the .c2 file) or in the decoder. In any case, if there is a need for the decoder to work with center frequencies other than 1.5 kHz, I’d be happy to make the change. I’ll wait for Bill’s recommendation before doing anything on this.
