No one wants the AM band to succeed and prosper for another 100 years more than me. But with the sideband sludge the IBOC drips on either side of the main channel, won't our Broadcast Treaties with our neighbors be violated?
Mexico has HD stations on the air. Eventually, they will likely approve it as the officil system. Canada has so few AMs left, the potential for interference is minimal... and the CRTC plus Industry Canada just opened up an inquiry / factfinding on HD since Eureka has failed in Canada.
Weren't WE (US) the ones who got Mexico to turn down the 500kw "Boarder Blasters" and play nice?
No, we were not. There was only one "supposed" 50 kw station and it failed due to the legal problems of its operator, Doc Brinkley, not the US governent pressuring the soverign nation of Mexico.
Mexico has / had these heritage "over 100 kw" stations.
540 150,000 watts. Still running.
730 150,000 watts. Now running 100 kw
800 150,000 watts. Now 50 kw because the market for AM night skywave died, and the local market requires no more power.
900 250,000 watts. Now and back then, still running.
940 100,000 watts. Now 50 kw apparently due to antenna issues in Mexico
1050 150,000 watts, now 100 kw as night revenues declined and they are mostly a local station in Mexico's 2nd market.
1220 100,000 watts then and now.
1570 250,000 watts in the 60's and 70's.. dropped to 17 kw when night paid religion no longer produced revenue. Now 100 kw for local market.
In recent years, the following have increased beyond 50 kw.
690 XEN 100 kw (and IBOC)
690 XETRA 77 kw day only
760 XEABC 77 kw
830 Mexico City 100 kw
970 Mexico City 100 kw
1060 Mexico City 100 kw
1110 Mexico City rumored to be 100 kw.
