clouseau said:[Well put. I have always been leary of bringing up on this board what the NAB already knows. The VAST majority of a station's audience is in the 70 dbu contour OR HIGHER. While I would not recommend it, I could see the 60 dbu limit raised. What I WOULD recommend is adopting it ACROSS THE BOARD, right now on FM. Right now we have 60 dbu, 58 bdu and 54 dbu, all in the same area. Doesn't make much sense to me. But that's because it is an arbitrary standard.

I would be nice to have just one standard. No argument there, but I'm not sure where you should set it. 54 dbu is not much of a problem for just about any car radio, but it is insurmountable for your average clock radio that cost $20.00 at the drug store.
I'm sure that most fixed listening is well inside the 60 dbu contour, but I suspect that many people in their car will hang on until the signal is close to unlistenable, assuming the station is broadcasting something they really want to hear. Our resident statisticians will tell us that most radio listening is done in fixed locations. Maybe so, but I wouldn't discount the folks in cars.
Making the assumption that HD eventually gains a foot-hold, then I suspect you will be seeing a lot more radios similar to the Sony, which can suck a signal out of almost nothing. We know the technology exists. Should they become common, where do you set the protected contour?
I’m sure that the FCC couldn’t care less that some people have really sensitive and selective radios, so they’d probably go for the worst case scenario experienced by a cheesy radio. It might be helpful if the FCC instead dictated some improved quality in consumer products. That will never happen ….
