Yes, the owner can change modules opjose but what makes you think that he has a 7202 or any other radio with a module? Nothing about it in this thread.
There are, of course, several manufacturers that produce radios that either have internal synthesizers or have standard or synthesized modules available. We were trying to keep the costs down here I thought otherwise I would have recommended a 2.4 GHz system.

Again, just get your crystal changed at a shop.
