In addition to what Gary said, I'd like to emphasize using gpsd's
decoding of RTCM. You can watch that and if it doesn't decode figure
out why and adjust your output. My guess is that adjusting for gpsd to
decode is also likely to be adjusting for receivers to decode.
My impression is that pretty much every receiver for a long time will
accept RTCM2 for pseudorange corrections. In the US we used to have
Nationwide Differential Global Positioning System

https://www.navcen.uscg.gov/?pageName=dgpsMain
which transmits RTCM2 at 100 or 200 bps on about 200 kHz. I used a
Garmin GBR-21 and a II+, back before SA was turned off, for trail
mapping, and the results were amazingly good.
