Dave,
As I understand it, the difference between DSM2 and DSMX is correct - DSM2 can use two frequencies, DSMX uses more.

As Helmut says, the two are compatible and the Rx/Tx pair will use the higher spec DSMX if it can, and DSM2 if one or both does not use DSMX. So a DSMX Rx will work with DSMX if the Tx has this capability, and DSM2 otherwise, as you surmise.

However, both use a "Spread Spectrum" signal which does not in fact use a single frequency for the data but spreads it over a band of frequencies. This gives the biggest part of the interference protection, and both use it.

Hope this helps
Frank
