NAB claimed LPFM's would cause "interference." For inexplicable reasons they had no problem with interference issues caused by higher power translators. Go figure. Truth be known every transmitter adds a little interference to the dial, but in the case of these low power stations, it is negligible, unless you happen to be trying to listen to an adjacent channel while sitting under the transmitting antenna. NAB went so far as to make bogus claims to Congress about the alleged problem. I suspect the real "interference" they were worried about was if someone is listening to a LPFM station, then they are not listening to one of their member's commercial stations.
I always thought it was odd that they didn’t look at LPFM as a source of new membership as well as a new market for some of their convention exhibitors. If hundreds of new stations come on line, the equipment has to come from somewhere. If NAB had taken a different stance, I suspect that more than a few LPFM’s would have joined, myself included.
After we got on the air, the Texas Association of Broadcasters (TAB) invited me to join. I did. I think we were the first LPFM to do so, but I believe there are several others now. It has been a good experience. I wouldn’t miss one of their conventions. TAB took the high road.
