Lonnie, Can your software code be adjusted to limit the country codes rather easily? Or, is this feature not delaying the certification process thus far? It would seem to me that the FCC would not certify the system if it can be adjusted by some operators to operate outside of US specifications while being in the US. It would seem to me that key generation would be where you could turn this feature on and off.

Those 2 port boards fit nicely. It would also help if you took part and helped to open up the cert process with us for the products you are specifying.
