[aprssig] Help setting up Kenwood D700A

[Dave Baxter]

"PG-4W (english).pdf"  published by Kenwood....  Page 76.

-Snip-

7 GPSTEXT
Short form: GPST Default: $PNTS
Parameters: up to 6 characters
Example: GPST $GPRMC
Function: When the beginning of the data input from the GPS port
matches the character string specified in GPSTEXT, the contents of LTEXT
are automatically overwritten by the input data from the GPS port.
The GPSTEXT settings are shown in the table below. If the beginning of
the input data does not match the GPSTEXT character string, the sentence
specified in GPSTEXT is reconfigured using the previously interpreted
GPS data and the result is used to automatically update LTEXT.
Sentences that can be interpreted Sentences that can be reconfigured
$GPGGA $GPGGA
$GPRMC $GPRMC
$GPVTG $GPVTG
$GPZDA $GPZDA
SONY $PNTS

(My Highlight)

So, it would appear to be used to specify a particular GPS NMEA sentence
to process and make available for a beacon, or pass to the PC.  And it
would seem that Sony may produce a GPS (or other location sensor) that
sends the $PNTS sentence.  Hence the comments in one of the Ui-View
doc's (not to hand) about it being popular in Japan.

I have yet to download a D700 manual, as I do not have one of those
radios.

We've drifted off topic, again, so enough, OK.
