Just as we thought, the NAB stirred the FM Modulator pot with their own testing so they could go crying to the FCC. Surprise surprise. This from Billboard Radio Monitor:

[...] NAB spokesperson Dennis Wharton says, “Our tests showed that 13 of the 17 wireless devices (76%) exceeded field strength limits set by the FCC. Six of those devices exceeded the FCC field limit by 2,000%. One device transmitted a signal that was 20,000% stronger than allowed by FCC rules. Many of the devices also transmitted signals that were substantially wider in bandwidth than permitted by the FCC, resulting in potential interference to 1st and 2nd adjacent channels as well.”

The NAB has sent letters to both FCC chairman Kevin Martin as well as Senate Commerce Committee chairman Ted Stevens and co-chairman Daniel Inouye notifying them of the results.

If they spent this much time on creating innovative programming, they'd have masterpieces.
