I just read the rules.  The shift is not specified, only the data rate 
as being 75 bps rather than 45 (or 45.45) bps.

The K3 DualPB filter for AFSK or FSK mode should work fine at this data 
rate.  The sidebands will be slightly wider due to the faster keying 
speed, so a 200 Hz roofing filter is probably a little tight.
