No point running gpsd with different debug levels if you don't send the
debug output.

gpsd got an RTCM3 type 1075 packet.

And sent it to the GPS.  That is what is supposed to happen.

Ignoring gpsd_ntrip.data as you did not send the matching output.

Looking at gpsd_ntrip1.dat, looks like the same data types as before.

    1006
    1008
    1013
    1033
    1075
    1085
    1095
    1230

Have you compared the receiver internal config between the gpsd run and
the str2svr run?  Did one of those change something in the receiver?

See below for my previous questions, still unanswered:

Yes, or no?

Can you get that?
