A Way Around the LPFM International Border Agreement?

Post by Paul678 » Thu Dec 29, 2016 2:00 pm

In Tucson, LPFM stations are restricted by the International Border Agreement, and are limited to 50 Watts transmitter output.

Phoenix stations are not bound by that same restriction. They're allowed to broadcast at 100 watts.

However, there is an LPFM station in Southern Tucson, that broadcasts at 100 watts, so there must be some way to get around that rule.

Is there a way to submit data to the FCC that will prove a 100 Watt Tucson station won't interfere with Mexican stations to the south?

This particular station has a minus 26 feet HAAT, or 26 feet BELOW average terrain, but increasing antenna height is not feasible at
this time.

You'll have to get it cleared by Mexico. Sometimes that is easy, sometimes it takes 10 years. Attached is the relevant bit of the US-Mex FM Broadcasting Agreement.

Ok, thank you for that info.

Clearly, Tucson is within about 75 Kilometers of the common border.

But going to 100 Watts requires approval from the Mexican government? You can't just deal with the FCC? What kind of data
do you need to send them to get approval?

And what are the "notification procedures in Article 8"?

The FCC International Bureau handles it. Believe it or not, it is illegal to go direct to the Mexican FCC with a request. You might want to call Gary Loehrs at the FCC and ask how you should handle this. You can look up his contact info here: https://www.fcc.gov/about-fcc/finding-people-fcc

It's been a while since dealing with coordination to Mexico, but aren't requests outbound from the FCC handled like they are between the U.S. and Canada? Something like two windows for official requests per year and then you wait?
