Re: HD Radio Questions
The only way they will ever make HD radio any better than it is would be to do the same thing that they did with HD TV. They need to go all digital and dump the analog. Trying to shove more stuff down the same pipe never did work well.

Subject: [sbe15ny] HD Radio Questions
Seems that an email to members@PROTECTED doesn't make it to the group. I must be doing something wrong...
Anyway, here is my original message:
I find myself a proud owner of a new car that includes a factory HD radio in it. (My old car with the add-on HD unit will be passed down the food chain.)
The HD listening in my previous car was been confined mostly to AM stations, and I noted frequent reversions to analog during my drive. I have been listening to FM HD Radio in the office, mostly to -1 channels to avoid multipath.
My question is: How many stations have implemented the power increase on their FM HD operations? I live about 45 miles west of the city, and HD radio from NYC is pretty spotty until I get about ten miles closer to the city. Cruising the dial last night, I was surprised to get good enough HD coverage in my driveway for some NYC station’s -2 or -3, but of course, not all of them. I do get a fair amount of HD Radio stations from NE Pennsylvania, but don’t spend much time on them (even in analog.)
My next question is: How many operators use and maintain their PAD data on the HD Radio subchannels? Users of satellite radio quickly get used to the title/artist or score data provided in these PAD services. I can speak from personal experience that I would like to know the format or title/artist being played on some of the -2 or -3 channels I cruise across. I assume that most of these services are automated, so this info probably exists somewhere in the service. I guess it needs to be bridged into the PAD data system. Even static data describing the station being simulcast (if that’s what it is) would help. I think that accurate PAD data would make the additional services more attractive and more useful.
Just my two cents worth. I’m amazed at how much of the content I “consume” is digital these days…
Regards,
Ken
