To add more fuel to the article bashing fire:

This is WAPA's Daytime Signal Propagation at 10000 Watts.
This is WAPA's Nighttime Signal Propagation at 9500 Watts

At local range not only does it cover all of Puerto Rico, but starts to hit the Dominican Republic. Even cheap AM radios should be able to pick it up over most of the island.

A higher quality radio (such as a car stereo since power is out over most of the island) should have no trouble picking this up anywhere on the island at any time of the day short of deep in a valley.

Night should have no issues whatsoever anywhere on the island in any terrain short of a crystal radio on the western side.

Also, WAPA has 6 affiliates stations (although they could be down) According to Wikipedia

I took my family and friends to Yellowstone prior to the eclipse. One of the families in my car happened to have two young children (ages 3 and 5). As we approached Yellowstone and cellular data service dropped to near-nonexistent, the two had a meltdown. They were screaming "I want YouTube" over and over for a good half hour, and their parents couldn't get through to them that YouTube was inaccessible here. They had never been without Internet connectivity all their lives. Meanwhile, AM/FM radio worked just fine.

I'm not sad to see music radio die. The entire thing has been a scam for nearly a century with ClearChannel owning most of the music stations across the country, and thus selecting which artists and songs become successful, instead of it happening organically via popularity among actual listeners. But the technology of radio broadcasts is far from dead.

We cannot hear WBGO in this area. Here is their coverage map:

My workplace is in Norwalk, CT. The Jazz station that changed format used to reach well past Fairfield.

Some numbers for my own comparison... KPWR (A popular Hip Hop radio station in Los Angeles) transmitts 25,000 watts of power. This article claims that it can pull 50 milliwatts. If this technology became standard on all cell phones, 1 million cell phones in Los Angeles would be able to pull a collective 50,000 watts out of the air.

LPFM stations do interfere with signals of larger stations. A local high school station near my house - WPHS - is supposed to broadcast on 89.1FM.

However WPHS interferes with "large" FM 88.7 CIMX broadcasts in an ~ 2 mile radius from the location of WPHS. When tuned to 88.7 FM CIMX , the static and interference from WPHS makes it impossible to listen to CIMX in the area. The inference is not isolated to 88.7 FM but extends to adjacent channels 88.5 - 89.9 FM and can be clearly heard in this entire spectrum - so clear that you would assume that WPHS was actually broadcasting on every FM channel in this range.

The FCC can easily force stations to relocate; they just refuse to renew an operating license on a particular frequency.

I'm not going to go through the entire FM band, but based on my first few tries, there are a number of frequencies that only have a few stations operating on them nationwide.

87.9 MHz, for instance, is only used (according to radio-locator.com) by two licensed stations: KAWZ in Nevada and KSFH in Mountain View, CA. The latter is a high school. Running a Google search turns up a few more stations (one pirate station in San Francisco, apparently), and WBAR from Barnard College. I don't think it would be a major national sacrifice to move them to some other channel in their respective broadcasting areas. So that would be the likely candidate for a national standard low-power frequency.

Most of the other frequencies in the FM band have less than 200 stations on them in the U.S. and Canada combined; some down around 100 and some as high as 200+. While moving 100 or 150 stations wouldn't be trivial, if it was done over a period of a few years it wouldn't be terrible either. I don't think it's nearly as impossible a feat as you're making it out to be, and it's something that we need to do in order to mitigate interference and prevent a bigger problem in the future as more of these FM transmitters become available, and integrated into more portable devices.

The major issue would just be getting the FCC to do anything, since it's basically bought and owned by the major broadcasting companies and organizations.

http://webjay.org - Calls itself "Listener Created Radio", and it aggregates quite a bit of radio and non-radio MP3, Real and windows content. You can create playlists of audio/video content already hosted someplace. When you click "play" on a playlist, it generates a playlist for your player. Worth checking out.

http://www.radio-locator.com/ - They track radio stations and list their stream links too

http://www.radio4all.net/ - Anybody can submit radio content to them, it's sort of a precursor to PRX but a lot less middle-of-the-road.

Wow! Next you're going to tell me to quit smoking weed!

And don't feed me that line of bullshit that you (or your 'friends') download music to protest/boycott the RIAA.

Ok, I won't... I download music to protest/boycott the pirates who sell unauthorized copies. Actually, I don't download music at all. Couldn't care less. I listen to the radio, but I change stations during the commercials. Does that make me a thief?? Actually, I listen to college radio, on the net.(WMXM In case you're interested. Find it here) Good free shit... Can't remember the last time I bought any music, but my memory isn't that good, so this statement means nothing.

For most US readers, I'd suggest searching for Australia, Canada, Ireland, New Zealand, or UK radio stations or just listen to blazznet: http://www.bmbient.demon.co.uk/blazznet/index.htm

I have a very small mind and must live with it.
