Hi, over the past year I tinkered with equipment to send video pictures from a model aircraft to the ground. The 2.4Ghz system that I have now is working well with very good range due in part to two patch antenna’s. The transmitter and receiver both have an audio channel with phono sockets which are not used. Can anybody suggest a circuit design which would convert serial data from my GPS module with a Serial Port Profile (Spp) output socket to send down this audio channel and be converted back on the ground?
Thanks Geoff
