I've been trying to install a TinyTel in a small FPV plane. Got everything put together, and confirmed power to the TinyTel, but observe no audio stream at the receiving end.
Unfortunately my bench testing is being conducted in an area with no sky access. Should the TinyTel send out an audio signal with non-GPS telemetry (like battery voltage) before it acquires a satellite lock? Or is it completely silent until it gets a lock, and then broadcasts all the data?
The answer to this question will effect my next move in the diagnosis process.
