ITU Region 2: Americas, Greenland, eastern Pacific Islands
Assuming that the user has a Ham license, the 5650 - 5925 MHz band may be used.
Note that all 8 channels of ImmersionRC’s RaceBand are legal in in this region, with a Ham license.
With the FCC power limit for analog transmissions being so low for license-free use, it is not very interesting for
race quad use. At present, ImmersionRC does not ship a ~1mW version of the Vortex transmitter module. This
may change in the future.
