so its -18* outside today so doing some reading , is anybody using option L Telemetry streaming data via radio ?
There is a thread somewhere here on TRF where a person interfaced an MAWD or a Stratologger to I believe a 900Mhz transmitter to stream the altitude in realtime. Took a fair amount of work to the point I felt I didn't have a problem with waiting to recover a rocket to see what the altitude data pattern was. You could take the easy way out and simply purchase an EggTimer TRS system with an LCD receiver. As part of the arming process, the LCD receiver decodes the lat/long stream but instead of using GPS altitude (which is fraught with inaccuracy) the field elevation goes to zero and the baro altitude is streamed directly to the receiver. Soooooo, you could get it all on one board without having to try to interface a radio to the altimeter. Plus get GPS tracking to boot for $140.00. Kurt
You can hook a set of $30 3DR-compatible radios up to an Eggtimer, set the baud on the radios to 19200 (the Eggtimer's baud rate), and it will stream real-time altitude/eta data as you fly. Of course, as Kurt suggests you can do the same thing with a TRS too, plus you get remote arming and GPS tracking, but if you need the airstart capability etc. then you're pretty much going to have to stay with the Eggtimer.
