FM transmitters under current rules (at least so far as I can understand the rules) don’t run with anywhere near 100 milliwatts. FM is limited to no more than a certain signal strength at a certain range, as opposed to how many milliwatts the xmitter puts out.
That is correct. There are some who will tell you that under test site conditions that the radiated output power to create the 250uV/M at 3 meters is in the range from nano-watts to less than 25mW. However IMHO, the FCC will not be knocking down doors with the BATF and Mod Squad at those power levels unless the operator is interfering with the licensed broadcasts of another service, TV included for those who like 87.9.
