That's correct. And, in most cases, if you stick with brands (Futaba for instance), you can re-crystalize the RX which is legal, and have an additional RX.

I have an Airtronics RD8000 system on channel 11 as well as the new Specktrum DX7. There is only one other guy in our club that uses channel 11, we don't often clash. But I am in the process of moving everything over to the DX7 system. I've done three so far. I really like the new system, but am still using the "older" RD8000. But, again, the new technology costs $350.00 to get started. New RX's are retailing for $99.00 each.

So, if you are not willing to part with the $$$$ then you will have to work out a compromise with the other guy. Our club rules state that the frequency pin is supposed to be returned to the frequency panel when the pin is not actually in use. That way someone else can use it when and if necessary.
