I am using somebody's PC at Shen Zhen so I can't use Chinese in this post .

Synthesized Tx modules ( Futaba 9Z, Multiplex, also JR in the near future ) and receivers are available today so some of us are already enjoying the convenience of not having to replace crystals when changing frequency. The Multiplex transmitters have built-in intelligence to make sure that there is no signal on the same frequency in the air before switching on it's radio part so if all of us are using Multiplex radios, there will not be any interference problems except for those created by external sources.

Whilst CDMA will help to simplify the design of receivers ( hence making them smaller and lighter ), it will also bring new problems and one of them is the well-known
