What page is that on ? On page 24 there is a formula for power. It is P=0.3E squared. Looks like he can use even more power than he has now.

UNLICENSED OPERATION

The next four sections cover the permitted forms of unlicensed operation in the AM band (535 to 1705 kHz) and FM band (88 to 108 MHz), and explain the penalties which may be assessed against those forms of unlicensed operation which do not fall within the permitted forms of unlicensed operation.

PART 15 DEVICES

Unlicensed operation on the AM and FM radio broadcast bands is permitted for some extremely low powered devices covered under Part 15 of the FCC's rules. On FM frequencies, these devices are limited to an effective service range of approximately 200 feet (61 meters).

Heh ! I am streaming and simultaneously ripping a foreign Disco radio station, and re-broadcasting on 98.1 FM with a 5 watt transmitter. Nice solid 3 mile range in full stereo. Piss on these greed mongers. My neighbors tell me all the time how much they like the music. America is great if you know yer way around !

If a home-built Part 15 transmitter does cause interference to licensed
radio communications, the Commission will require its operator to cease operation
until the interference problem is corrected. Furthermore, if the Commission determines
that the operator of such a transmitter has not attempted to ensure compliance with the
Part 15 technical standards by employing good engineering practices then that operator
may be fined up to $10,000 for each violation and $75,000 for a repeat or continuing
violation.
