I just finished getting approvals for a 916.5MHz telemetry system. The 902
to 928 MHz band allows for continuous transmission making it popular for
cordless telephones and telemetry.

There is a severe restriction on transmission duty cycle in the 410 to 470
MHz band.

In any case the regulations for intentional radiators are complex. I suggest
you start building a relationship with a local test lab/compliance firm.

Check out these FCC publications for more information:
OET Bulletin No. 61
OET Bulletin No. 63
