Mexico Has About 20 HD Stations

[Barry]

Viewing the hdradio.com website, I saw a list of HD radio stations south of the border. It had about 20 stations, including 2 on AM. That website's lists tend to be quite outdated, at least for the U.S. But it is at least an indication that HD radio is spreading a bit outside of this country.

There's a different list on the Mexican government's COFETEL website, of stations authorized to use HD Radio. The COFETEL list contains more -- and different -- stations than the hdradio.com list. It also indicates that as of this past spring, only four of the stations authorized to use HD were actually using it.

I'll see if I can provide a link tonight. (hopefully David or someone else more fluent in Spanish can confirm I'm understanding it properly!)

Are the AM's in Mexico by chance any of the old 'super power' AM stations? I could only imagine the HD buzz from a 100KW AM station.

Mexico is gradually eliminating about 85% of its AMs, so it's unlikely anyone is investing in AM HD, although the 100 kw operation on 690, "La 69" was used to test HD several years ago.

I don't think HD sidebands are much of an issue here in the deep south, but the situation up in New England is a lot different. How is FM spacing in Mexico compared to the US?

I was able to actually see, via e-skip, the RDS readout of XEDA 90.5 with the HD logo back in January or so. I also briefly did see its RMX HD2 (in June or so) but it only decoded for one second.

They have comparable separation as the US, however, they will license a low power (5 kw or under) public or community stations on a second adjacent, but big signals are generally separated by 3 other channels.

Radio Info poster Fred Cantu has a site with all Mexican stations, and it is very accurate... http://www.mexicoradiotv.com/index.html

Take a look at the big market separation.

But how many HD stations does Sri Lanka have??

After driving around with an HD radio for a while, I wonder if it is viable in Mexico with mountainous terrain. I would think any sort of multipath at all would cause HD to lose lock. I've noticed that near buildings, even on strong locals. It dropped out into multipath on analog.

What really concerns me about HD is that it does NOTHING to counter the very problems it was intended to solve - interference on AM, multipath on FM. It it caused crummy reception before, it will cause HD to drop out of lock. A more robust system would be better.

Mexico is not all mountain... any more than the US is. There are plenty of flatlands... even the Valley of México (Distrito Federal) is a dried lake-bed surrounded by mountains. There are flat areas, hilly areas and areas with mountains, just like the US or Canada.
