<div>I think the trick would be to simply record the polling message and clean up the wav file (in this case). I gave up trying to decode on air (not that the 600baud signal is that difficult, it was more of a time issue), and use use a "dummy" rino110 in our comms trailer hooked to an external antenna. It hears all the local rinos and a script downloads the waypoints every 10 seconds and looks for the changes. Any changes in waypoint position cause that waypoint to be forwarded to an xastir server port.

<div>I have some rinos and can play however.</div>

spyke555@yahoo.ca</a><br>Sent: Friday, April 20, 2007 3:16 PM<br>Subject: Garmin Rino protocol<br><br>... I recently found your article on the Garmin Rino on-air<br>protocol and found it most interesting. I was just wondering if
<br>you are still interested in persuling this at all?<br><br>I've been looking at your recordings (both test and wav and<br>found an algorithm that does a descent job at deciphering the<br>peaks from the noise.<br><br>
My interest is somewhat different that yours though. You see I<br>already have the GPS and the FRS radios, just looking to make a<br>circuit that turns the two into a Rino of sorts. Yes I am aware<br>there are trackers and anti-trackers that are currently
<br>available that will do essentially the same thing and then<br>some... But I'm trying to do this as inexpensively as possible,<br>and the simplicity of the Garmin on-air protocol does appeal to<br>me as it would be very easy to implement in a PIC or similar
<br>device both for sending and receiving.<br><br>At any rate, I've developed a little program that allows you to<br>create your own wav files with control of every bit in the<br>message. The thought here is that if one were to braudcast this
<br>out via an FRS radio, the Rino's listenning should decode and<br>respond. Thinking this may be an interesting way to further dive<br>into the protocol, assuming of course that the check-sum (if<br>any) is not critical for accepting the message...
<br><br>My problem is that I don't have a Rino myself, so can't test<br>this on my own... So I was wondering if you still had any<br>interest in this and if you would be willing to try out the<br>application?<br><br>
Do let me know, and I'll send it over!<br><br>Sandy Pyke<br>----------------------------------------------------------------<br>----------<br><br>Québec Secours - Commandant - District 10 (Montérégie)<br><br><br>_______________________________________________
