Mexican Governmental Mediumwave List Updated

About a month ago, the Mexican government finally updated their official mediumwave station list, now dated June 30, 2011. Updates to this list do not come very often, perhaps every year or so. The previous list was dated December 31, 2009, 18 months ago. It's been a long time coming.

The list, in .PDF format, documents station location (city and state), owner, call sign, frequency, daytime and nighttime powers, and license expiration date or status. It is unfortunate that actual latitude and longitude coordinates of transmitter sites are not included. However, latitude and longitude can be extracted from the matching entry in the US FCC database if you look carefully and wade through the huge number of redundant and outdated Mexican records to find the right one. I am working on creating a combined list using my Radio Data MW program. That will allow the creation of a list in many forms, sorted at will by call sign, frequency, power, location, signal strength, etc.

To my knowledge, Mexico does not maintain an internet downloadable, official database in file form like the FCC or Industry Canada does. It would be nice if they did.

I wonder if any North American Dxers have managed to tune into any European AM radios stations ??

Is this technically possible ?

PS: I am awaiting delivery from China of a Tecsun PL-380 radio.
I liked your excellent review of this set.


Hi Claude,

Europeans are receivable in North America when conditions are good, particularly eastern and northeastern North America. Check some of the DX sites, and Yahoo's ABDX and ultralightdx.

Good luck with your new Tecsun PL-380. It's a fun little radio.

Thanks for your reply R.T.

Still waiting for my Chinese toy...

I never tried tuning into North American AM stations.

Must be fun...

I have a Realistic DX-400 PLL receiver connected to a 100 feet antenna installed in my back garden..

A lot of noise in Welling, a London suburb but I manage to get some ssb traffic, amateurs, tropical stations (South America)and 4 Long Wave stations (4 French, 1 Irish and 1 British).

I used to be on CB but this spectrum is now pratically dead In Britain.

Regards from Welling

Hi Claude,

Yes, get as far from noise as you can. I like to take my radios out into the garden or down the farm road away from the electrical grid. It works well. And build yourself a tunable passive loop antenna to couple to the radio loopstick. It will increase your reception tenfold. Best results are often at sunrise and sunset times.

Good luck to you.
