Subject: [aprssig] StreetPilot question
Man, it's quiet in here...
Got a quick question about Garmin's automotive navigation receivers, like
the StreetPilot and nuvi. These all seem to have USB interfaces, and I
know they'll act as a mass storage device for POI/map transfer, but will
they work like a regular Garmin USB GPS receiver, and provide
position/velocity/time data to a mapping program? I've never used any of
this generation of products.
Thanks,
Scott

Subject: [aprssig] APRS -- Chicago to Mackinac Island sailboat race
This July about 300 sail boats will be participating in the Chicago to
Mackinac Island sailboat race. This race (333 statue miles) is the longest
annual freshwater sailboat race in the world. Over half the fleet will
carry satellite tracking units. The trackers use the Orbcomm LEO satellite
system to email boat position reports to a web server. Family members (or
anyone) on shore can go to a web site and see the boats plotted on a chart.
A few of the sailors are also hams (myself included). Us sailing hams
would like to plot our boat position reports on APRS. I can do this
manually by using WinAPRS; going to station settings and manually inputing
boat position; then going to TCP/IP settings and connecting to APRServe
Network. This works fine but I'll be racing on our boat. I need to
automate this process.
My plan is to receive the Orbcomm emails with our boat position reports.
Parse out lat. lon. speed. heading. date and time and form a raw packet.
This I'm capable of doing this. I need help in how to send the raw packet
to APRServe Network. I would appreciate any help you can give me.

Bill,
I live in Rockford and just wanted to offer my services if you need someone
to man the radio on the boat. Never been on a sail boat before. :-). I
did occasionally get sea sick though when stationed on the USS Sterett
(CG-31).
Hope you have a nice time!

Actually, it was Dave (KG4YZY) who did the testing. He was using a Kenwood
TM-271A and KPC3+ into dummy load with sample port and two D700s. The
reason for the slower decoding is the D700 uses squelch CD instead of
software CD.

Bill,
I hope this doesn't sound stupid but why not use APRS itself to parse
packets to I Gates while you sail? Just beacon your position @ 10
minutes and let the established net of digis and gates to send your data to
the net.

Google is your friend.
The first part is the hard part, the rest is just connecting to the
APRS Internet System, here is info on the login string
http://www.aprs.net/valid.html
If you don't have the validation number for your call, here is the code
http://www.cnunix.com/ftp/hamradio/tapr/aprssig/aprsspec/aprstcp/
validation.c
Then just form an APRS packet and send it. The APRS protocol specification
is at
http://www.tapr.org/aprs_working_group.html

Yes, I have one........works quite well. The TRConfig software for setup is
also quite good. The only Packet program I know works with it, is
Paxon......which leaves a lot to be desired :-( Why they used a USB
interface, I do not know........many other Packet programs could be used IF
it had RS232. Its Packet operation has no mailbox etc.
As a tracker, it has an output to power up your radio, shortly before
sending an APRS posit, after its done, it goes back to sleep switching the
radio off. Repeats the process for each APRS Posit.
I asked the makers IF a mailbox would be installed in future firmware
revisions.....was told no.
Cost is high, compared to Tinytrack and others, A$500 or so. It does
generate quite a bit of radiated "noise" on the 10MHz APRS freq, however
careful routing of cable and physical placement can eliminate the problem.
It has NO digipeat function either.
One feature that is excellent, is it can receive off-frequency APRS packets
and is able to "lock on" to them very well......I would suggest the
hardware design is very good, however it is let down badly by firmware, USB
interface, and possible lack of future good firmware features etc.
Just my 02 cents worth :-)
