Radio Currents reports that the first two Mexican stations have started broadcasting in HD Radio.

XEEZ 970 Radio Palacios is broadcasting an AM HD Radio signal from the U.S./Mexico border town of Caborca, Sonora, using a Broadcast Electronics transmission system.

XHTY-FM 94.5 in Tijuana on the FM Side has installed a Nautel V10 HD Radio transmitter. The station is operated by Uniradio.

Radio-Locator Decoded

I have received a lot of questions about the contours shown on the Radio-Locator maps. For AM they are:

Red – 3.0 mV/m – Generally the Sellable area of the station
Purple – 0.5 mV/m – Rural protected service area, but nobody would buy ads.
Blue – 0.1 mV/m – You might still get it on a car radio

For FM they are:

Red – 60 db/uV or 1.0 mV/m – Protected service area for Class A and C stations
Purple – 50 db/uv or 0.316 mV/m – A pretty weak Signal, nobody would buy ads.
Blue – 40 db/uv or 0.1 mV/m – You won’t pick it up, except in rural areas

I determined this by comparing the plots of sample stations in Radiosoft’s Comstudy with their Radio-Locator maps. Hopefully this clears a few things up!

ITU approves Digital Radio Mondale for Tropical Bands

According to Radio Magazine, the ITU gave the green light for DRM digital broadcasting in the tropical bands. Although not strictly an AMBand issue, it is creeping close, since the tropical bands are just above the high end of the US AM band. You can read the full article here.
