Hi All you R/C techies -

I have an unusual RC application I need help with! There is actually two parts to this application. What this is all about is separately and independly controlling one of nine totally different items from nine different positions. The servo needs to be 32inoz and there is only one per item. It will be used to turn an arm 90 degrees. So each item needs to have a separate frequency rc reciever and tansmitter. The servo and reciever are mounted independently of any other reciever and servo! The range needs only to be within 300 feet actual 100 feet might do! There can be no interference between any of the nine items. The reciever and servo will be battery powered and the transmitter can be either battery or power supply as they are in a fixed position in nine different locations.

Now the second part of this is to control each transmitter from a central computer so that any one item or selected items or all items of 9 can be activated at once.

Any ideas for a single channel recievers and transmitters with enough bandwidth to have nine operating in a small area without any crosstalk. How about a multiplexer to control nine transmitters.

Told you it was odd application.

Thanks
Mike -
