Appendix C: Video Tx - Staying Legal
Depending upon the Vortex variant purchased, and the Tx module installed, the video
transmitter power output level, and available transmit frequencies can vary.
It is highly recommended to understand the rules and regulations in your country before using
the Vortex. Transmitting outside a legal band is something frowned upon by the authorities,
and may result in a fine, or confiscation of equipment.
As a rule of thumb, the following charts should help understand which frequencies are legal in
each of our main markets.
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.
