    Correct me if I'm wrong, but 915 MHz. is smack dab in the middle of one of the Amateur Radio Bands. You're going to need a license to operate there bud.

    IIRC it's Region 2 under the ITU Region classifications. As for operating there, I know 915MHz is one of the ISM bands used for dielectric heating applications so there is some competition for the band.

    Yes Region 2 covers most of North and South America, and bands have both primary and secondary users. Secondary users may not cause interference, and must accept interference from primary users. Generally speaking , being a secondary user on a band is...well...challenging.

    The following chart does show ISM @ 915 ± 13 MHz. in addition to Radio Location as secondary users
