Part 15 LPAM vs LPFM on mountain

I meant a part 15 LPAM or LPFM Transmiter. 

is under the rule of the fcc. fcc rules apply. given puerto rico's aging electrical infrastructure you may have very good results using neutral loaded carrier current along with a distributed network of part 15.219 am transmitters.

i do believe puerto rico is still allowed to make use of Class D 10 watt licenses iirc. you may try to form a non profit and make a class D non comm station or a small class A non comm.

because you are covered by the fcc your legal options are limited and the PR FCC is very vigilent about stomping out pirates when they pop up. also forget LPFM the window has come and gone and who knows when a new one will open up.

due to the political and economic climate currently in play down there (crashing economy), that licensed stations may not take kindly to you encroaching on their territory and grabbing listeners away which equals loss in the rating losing them ad dollars. you will likely be quickly investigated so i would make darn certain you are 100% legal.

here is what your AM/FM dial looks like in your area listed on your profile

Thank you

What's interesting to me is how much range the Puerto Rico AM broadcasters are getting! In my area it would be lucky if a high band AMer, say at 1600 khz, could reach 15 miles with the red circle coverage at Radio-Locator, with a few kw. One station was 80 miles away and putting in very strong signals with 5000 watts, the meter was pinned! That kind of signal strength is unheard of where I live in the North.

It made me think how well a Part-15 AM station would work with such a conductive ground, but then I note on the stations list that the AM band looks mostly full and must be difficult to listen to, with adjacent channel interference.

PR might make a good case for community radio stations with under a hundred watts, on what looks like a vibrant AM band, if a frequency could be set aside for its use. It would seem more challenging to get range and listeners using low power in my city, as compared to PR.

I realize that I didn't give my thoughts about your question! I was too fascinated about your link to Radio-Locator.

With your height on a mountain, that would be an advantage on FM, since the high FM frequencies like height above the terrain. If you can see many homes and roads down the mountain from your site, you may be able to reach them with a fairly low powered transmiitter.

AM isn't always that great from a mountaintop, since ground water is much lower, and mountaintops are usually dry places. AM might be able to work if you use lots of radial ground wires laying on the earth.

FM transmitters are available worldwide in every power level, and at reasonable prices. AM transmitters are scarce by comparison, and more expensive for a decent radio on AM. You can find a Talking House transmitter that puts out 0.1 watt with an automatic tuner inside, for a fairly low price. There's also a Spitfire transmitter out of the UK.

It depends on many different factors to decide on which radio you can use, like the money you can spend for equipment, range you're looking for, transmitter site space you have, whether you want to do live programming at your studio, all automated or from a network stream.
