Were you aware of the Base91 telemetry extension described at: http://he.fi/doc/aprs-base91-comment-telemetry.txt It allows telemetry data to appear in a posit...

I mean I came up with a more flexible format for telemetry, and I'm trying to talk Hessu into supporting it. If aprs.fi can handle it, that's what most of my...
Scott, I've sent a few of those packets to the APRS-IS servers, they did appear to go through to aprs.fi... There was a little sillyness until I resent a ...
... The base-91 has the variable length concept... The metadata sounds like the existing parameter definitions just with a different coat of paint. Sounds like...
I wrote up a sheet about it some time back. If I can figure out where I put it, I'll post it to the wiki. Scott...

In about a month I'll be out with a bunch of friends tracking and chasing a high altitude balloon payload across the southwest US. my chase setup will be a...
... Are you limiting the equipment used in the chase to just the radio, OT2, and Nuvi350? Will you have a laptop along as well? The best you can do is set a...

... I'd rather just use the nuvi 350 and t2-301, otherwise what's the advantage of the t2-301 nuvi combo? If I need a laptop I might as well just run ...
It seems to be the same problem with power control when digi as for aprs message. I am using my excellent tracker as a digipeater but the power relay stays on...
If there is a way you will have to do it within the T2 software. I don't think you have that level of control with the Nuvi. If you don't think you will get...
... You tell me what the advantage is... The only advantage I see is less equipment in the vehicle, but you are limited to the capabilities of the equipment...
I'll second James comments regarding the PATH in your APRS payload... Here in Oz we use custom HAB hardware and firmware (http://rfhead.net/?p=476) that has no...
It was always assumed in the design that you wouldn't use power control with a digi, since it can't receive packets to digipeat when it's turned off... Scott...
Been running Argent gear for a long time. My T2-301 and nuvi 350 has been a super package. Been looking and making some gear changes and I need some info on...
Folks Several very nice capabilities of the Tracker and the Nuvi 350 combination are the ability to send commands to the Tracker, such as switching profiles or...

... Not with the GTRANS you can't. If there's messaging support on the GPS port, it's for the AvMap. I don't think that was implemented when I got my D710....
I did implement AvMap support - it ought to be in the development built at least, but I haven't gotten around to documenting it yet. I'll be happy to jump on...

Do you have documentation on the AvMap messaging interface protocol? If it is open, I could implement such an interface to the D710 and have it ready if they...

Ah that is a good question. We're not 100% sure.. There have been HAB experiments where people have let balloons go and tracked them for the past 30 years,...
