Hi all,
I am looking for the simple DIY circuit to use my video transmitter audio channel as GPS data channel for GCS and I used these circuits from http://ieee.uow.edu.au/~daniel/projects/radio_link/.
I just added IN4148 diode, 220 resister and 5.6V diode in to TX input and assembled full RX circuit, but I didn’t get good result.
Please look at these circuits and give me advice to get GPS data trough video TX audio channel. ( I check the http://dzl.dk/projects/electronics/modem/modem.html, but I haven’t any experience to program ATTINY chips)
Regards
