So you were the first ! And one good and one excellent solution. Would be really great if you could provide more details on your current solution for the DX7, e.g. diagram and firmware / source code.
In principle with your solution I could image that you could even modify the DX7 so that you can put multiple switches onto one channel and then use additional outputs on your "receiver" to split them out again. That would e.g. allow activation of different flight mode, airpressure sensor, compass, different GPS modes, return to home, over a single channel with several switching resulting in different binary numeric values.
That is not so easy, as on the transmitter side the SPI communication between the Microcontroller and the Cypress RF chip seems to be quite complicate, the microcontroller does all the bitstuffing, FEC things and RF Chip registerhandling . To insert more datas it would be nessecary to understand all this in detail. (better get the firmware ripped out of the transmitters microcontroller)
So the things feed into the transmitter RF chip is not that what comes out on the serial communication from the receiver boards.
Re the WL1000 FS solution, is it only the antenna which needs modification, or is this receiver also restricted to a single module with no ability to add a satelite receiver?
there is no possibility to add additional receiver modules to the WL1000, so the only thing that could be done is to tweak the antenna as good as possible, this is not a easy task and seems to be more magic than sience on 2.4Ghz :-) but after a lot of tries i had quite good success, but this is still ne finial solution.
