[8D] I would like to learn about telemetry, and the electrtonics involved. Particularly about sending GPS information over the audioi chanel of one of these wireless video cameras.

I don't have any idea, where to start , can anybody give some pointers?

are there any forums, or websites?

Greetings, Rudolf.

Start out by reading the latest issue of the AMA magazine and Model Airplane News. Both have articles referencing the equipment you describe. Making contact with the people named in the articles would likely provide more practical info than just about anywhere.

Systems such as you describe are also advertised in the major R/C magazines.

[>:] I will try to contact some of the mentioned people, but I really would like to know about a mini course in these specific areas of electronics and programming.

Rudolf.
