Xastir already does this. Curt and I worked it out and we've used it
in a SCSG drill to test. Xastir has a timer that downloads waypoints
from a "host" rino unit and transmits the positions as aprs objects.
You must name your rino with the first 4 characters of APRS, so my rino
unit would be APRSkd4rdb. xastir will download all waypoints starting
with the first 4 APRS, lop off the APRS, and use the rest of the rino
name as the object name. In this example the rino unit APRSkd4rdb
becomes kd4rdb on air. So far this only works under native linux
xastir since it requires the GPSMAN program to talk to the RINO and I
haven't been able to get GPSMAN running under cygwin (windows),
although the author says it will.<br>
<br>
There are a few quirks... xastir doesn't keep track of the last update
time on a particular contact, so it treats all as new. It would be
nice if xastir kept a table of rino contacts and positions and if a
position changed then and only then would it transmit a rino object.
This would facilitate handoffs where the rino users could wander from
one area to another and if multiple copies of xastir were running the
ones you had gone out of range of would not keep transmitting old
positions. Curt did a great job getting the rino code working for me
when I needed it back in October last year, so I ain't complaining!<br>
<br>
I did speak to Keith Sproul at Dayton this year about supporting the
rino units in the same fashion under winaprs and sent him an email with
the details, but haven't heard a word yet. I'm sure he's busy
generating new serial numbers for winaprs.<br>
<br>
I bought a Basic ATOM processor last year and started tinkering with
the DISC out of my police scanner on 462mhz. I was able to record many
position reports and see the 600hz data. My rino unit is able to
maitain lock inside my house, so that makes collecting data so much
easier. Alas, we had a new baby on Oct 29th, and I haven't had quiet
time to play since.<br>
<br>
Also.... FRS rules prevent you from modifying the antenna, but GRMS
units allow for external antennas <ahem> and rino's latest
firmware update lets it send positions when in GRMS mode.... though it
won't send positions via repeaters AFAIK. Now since modifying the
radio upsets the FCC certification, you can't transmit with it.... so
add a good antenna to the "host" radio, hoist it up on a pole and use
it for receive only. You won't be able to poll other rino users, but
you can eavesdrop on them as they QSO and send position reports. The
radio can be powered remotely via the serial cable.<br>

<pre wrap="">Decoding the GARMIN RINO's for APRS:
Maybe its time to start working on decoding
the Garmin RINO GPS/FRS radios again for APRS.
As everyone recalls, there were people on this sig
that squashed the effort claiming it would be illegal
to try to figure out the proprietary on-air format
used by Garmin for receiving and display into APRS
via a sound-card. And that pretty well stopped all work.
But reading below, it seems that Garmin is well
aware of our efforts and even refers people to
our project web page...

<pre wrap="">I sent an e-mail to Garmin tech support and they
sent me a link to your website as their only
response, so I don't think they would be against
it. They certainly didn't tell me that it wasn't allowed.

Seems such a waste not to be able to plot these
radios just as if they were APRS...
