That's an excellent way to lose your ham license while courting a $10,000
fine from the FCC for unlicensed operation. Current Part 15 rules permit a
MAXIMUM field strength of 250 microvolts per meter at 3 meters from the
transmitting antenna. If you check the FCC Enforcement Log, available on the
Enforcement Bureau page of the Commission's Web site, you will see numerous
people who got busted for transmitting in the FM broadcast band without a
proper radio station license. A few of these show up every week. If the
bootlegger is a college kid or a preacher who puts an unlicensed station on
the air as a hobby or to broadcast his church services, he may get away with
a warning not to do it again. Since you are a ham, and, therefore, licensed
by the FCC, you would lose your license and be hit with a heavy fine. Your
radio equipment could also be confiscated. In Florida, you would also face
state charges, as the Sunshine State passed a law a couple of years ago that
makes unlicensed operation in the broadcast bands a felony.

BTW, the FCC just levied a massive fine against Ramsey Electronics for
marketing "export only" FM broadcast transmitters that did not have FCC type
acceptance for regular broadcast use.

The bottom line is, such equipment is illegal. And the FCC is vigorously
enforcing the rules that apply to the AM and FM broadcast bands.

If you want to hear your AM roundtable while you are called away to the
telephone or using the bathroom, get a good speaker, attach it to your
receiver, and turn up the volume.
