No specific request for specific sentences in there.  Just general
wichfulness.  Do you have specific sentences you have that need
decoding?

Is that the exact model you still have?  Differences between NMEA
talkers are huge.

That log has the follwing sentences:

Always empty, no data:

    $GPAAM
    $GPAPB
    $GPBOD
    $GPGLC
    $GPRMB
    $GPXTE
    $SDMTW

Already handled:

    $GPGGA
    $GPGLL
    $GPGSA
    $GPGSV
    $GPRMC
    $GPVTG
    $GPZDA
    $SDDBT
    $SDHDG

Not supported, but mostly duplicates $SDDBT:

    Depth:
    $SDDPT,5.2,0.4,*78

Not supported, but similar to VTG:

    Water Speed and Heading:
    $SDVHW,230.0,T,228.7,M,6.8,N,12.7,K*76

Not supported:

    Transducer Measurements:
    $IIXDR,C,,C,AIRTEMP,A,-1.0,D,HEEL,A,2.4,D,TRIM,P,,B,BARO,A,-4.3,D,RUDDER*29

    Dual Ground/Water Distance:
    $SDVLW,,N,545.6,N,1109.4,N,393.6,N*44

    Wind Direction & Speed:
    $WIMWD,326.6,T,325.2,M,11.4,N,5.9,M*65

    Wind Speed and Angle:
    $WIMWV,100.2,T,11.5,N,A*13

Is that what you want supported?
