The ideal would be to use the DJT module (on the 9x) as an RF source. It is fairly easy to knock up a simple 2.4Ghz sensor system. The ideal would be to feed the output of the sensor into an audio amplifier so the audience can hear the signal. This depends upon the form of modulation that is used of course. So has anyone actually listened to the output of a Frsky DJT module and if so is it usable in this situation?
Of course any other suggestions are welcome.
