Any website displaying HD Coverage Maps?

P

Pete Pyeatt

I expected radio-locator to plug some in, but that has yet to happen. Are there any websites that display coverage maps for the HD2s and HD3s?
 
The red is audiomystic.
With stations still running 1%, a new coloUr is needed.
 
Its going to depend what type of HD coverage you want. Are you listening on an Insignia portable or a HD Radio connected via a rooftop antenna.
 
We feel that the standard should be 90% coverage for a car deck with a ¼ wave, 90º vertical pole.

Radio-Locator is DOA and doesn't seem to be updating anything anymore.

As far as FM though, the red (local) circle is usually a good rough guide to decent HD reception.

Using ZIP code analysis over many years, 95% of the at home and at work listening takes place in a contour about 20% smaller than the inner red contour. Since at home and at work listening is about 70% of all listening, the red contour is bigger than the useful analog coverage area.
 
The 60 dbu area of the analog coverage maps seem to be fairly accurate for HD until you get into the situation where ERP is derated due to antenna height. When the HD signal is 1% of 50,000 watts the close-in coverage is pretty good. When the HD signal is 1% of 4,000 watts (like on Sears Tower) that 40 watts doesn't come close to covering the inner red circle. The other problem is that HD signals are often degraded due to adjacent channel interference, much as the adjacent channels are degraded due to HD. So any realistic attempt at coverage maps would be fairly difficult.

For FM, HD is reliable while moving within the 80 dB contour. It can be heard with a really good outdoor antenna and the best HD receiver in the world within the 40 dB contour. For AM. you don't need a coverage map. If you can see the tower and there's no thunderstorm you can get AM in HD.
 
My personal experience with AM HD is that stations at the high end of the dial do best while for anal og, those low end stations of course go farther.

I wouldn't trust a d**n one of them to be accurate.
