Actually, channel 1 (which operates on 910MHz) of their "900MHz" video transmitter is legal as long as you have your Amateur Radio License (HAM operator). Legal operating frequencies on that bad are 902 to 928 MHz.
Keep in mind, this is for the US. Rules may (and probably do) vary for other countries. Here is a useful chart for HAM frequency bands: http://www.arrl.org/FandES/field/reg...ands_color.pdf
