16069Re: [tracker2] Which Tracker to use?
- Nov 26, 2013I have the WiFi mesh covered with Linksys routers flashed with OpenMesh/DD-WRT, though it reminds me that I need to come up with a better solution for deploying for EMCOMM. I have one set up now with a high-gain directional antenna and a medium-gain omni antenna on a tripod, with a waterproof box to hold the router and possibly a battery, and 100’ of CAT6+ cable.I thought having the nuvi 350 was a good idea as it can also be used as an interface to read and send APRS messages on the standalone systems. Didn’t even consider the announce/triangulate option. I also have TH-D72A HTs which can digipeat and do it while portable, but my idea was to have one or two of these ammo can setups that could be deployed in remote locations or in an EMCOMM situation with a vertical, a battery and solar panel.I’m still considering what to do with an RPi. There are a lot of possibilities.Ain’t this hobby fun?73 de KA5TRO

Nuvi 350? Probably OT3m.
Pi? Well, you could build a WiFi mesh with the Pi, as well as doing
sound card packet, but you have to had USB WiFi and USB audio.
Any time you're putting up a digi, having it locate itself and announce
periodically isn't a bad thing. You might be able to triangulate from it
