RE: Crystal Swapping.. Again
SoCal, call them and ask them if you can get one for your sailplane.
I know it is very hard to understand a spread spectrum system, when all one has been exposed to is a narrow band system. THese systems are designed to coexist in a given band of frequencies. If I can find some links I will post them. I am not an expert but I have learned a lot in the last couple of years. Our flight system is frequency hopping, and I am using a Direct Sequence system at work for an automotive application.
