Super Pro FM Stereo Radio Station 1 WATT Kit

In the United States it is only legal to transmit about 200 feet on FM under Part 15 (unlicensed). This is measured in terms of mv/meter. The most important consideration is that you never cause interference with licensed users of spectrum. This particular transmitter sends out image frequencies and spurious signals. If you want to use something like this you would be well advised to only use it on your own private island.

Misleading Ad... In bold text it says 1watt kit.. But at the bottom it says 25mw output.. In fact lower than other a that claim .5 watt or 50mw.. Read carefully these ads.. Looks to be a well designed unit though..
