Thanks for the replies everyone. Looks like I need to build a TNC and have the TeleMega send APRS :-(. Keith, is it possible to add a feature to AltosUI to output NMEA formatted strings on a serial port on the PC running the software? Can I put that in for a feature request please? That would be a nice elegant way of getting the necessary info out. Regarding my system, I am using the system detailed in these couple of links:
It seems to work quite well from an implementation point of view, and I am now at the point (functional and calibrated) where I need to send it some location packets to test functionality. Stewart

I am setting up an antenna tracking system that needs a data stream out of? the TeleBT? (or attached computer) that I can feed to the antenna tracker to have it follow the rocket automatically during flight.? How do I go about getting something like that out of the TeleBT or PC please??? I need something like a NMEA GPS stream, or similar.? NMEA would be great as the AAT will decode this without additional tweaking of the packets.? The data is obviously there, I just need to port it out somehow.

If you did that you could leave your TeleBT as is and instead use an APRS TNC to output the APRS data via serial into your computer. I run all my GPS enabled Altus Metrum products this way as it's a fully independent telemetry link (excluding the transmitter of course) which can be useful for troubleshooting from time to time. The only downside is that if you enable APRS beacons you won't have Altus Telemetry whilst the APRS packet is being sent as the transmitter can only do one thing at the time. To my understanding it doesn't interrupt the data logging on-board though, only the in flight telemetry stream. I hope you're well mate.

I?ve been thinking about designing something myself. I was planning to use the output from a TNC rather than depending on getting the data from the TeleBT or TeleDongle. I was planning to mount the antenna to the roof of my Jeep when at the field so I figured I?d just take the TNC output from the Kenwood TM-D710G I have mounted in the Jeep.
