Part 15 FM mw constellation network

"basically you need to run mono on part 15 fm to maximize s/n ratio and therefore achieve maximum range."

And with such a system highly expected to adhere to 250uV at 3 meters from EACH antenna at EACH TX point, and to get the maximum range ya obviously mono is the way to go.

Frankly I think AM would serve this purpose even better and get FAR better range and LESS TX point expenses etc etc etc.....yall know the deal why do I need to repeat it!

Cheap and quality?....well I suggest AM.

The pirate radio ships tried operating in international waters 3-miles off shore from New York City, but the FCC went out there anyway and raided the ship. That was many years ago.

Is there also a 3-mile limit in the sky? Maybe we could put a hot-air balloon up there with 999-Watts and wait to be smashed by a drone.

That is probably silly, but theoretically, does it have any value just for conversational purposes?

they got busted because the fcc got permission via the state department from the country the ship was registered in to go raid the ship.

when you do that it needs to be registered in a county that has no diplomatic relations with the usa or is unlikely to (and has a history of) not cooperating with the us on stifling freedom of speech issues.

like maybe sweden. they don't enforce us copyright laws there.

Those ship pirate stations had better swap out their sail boats for speed boats because with the passing of the NDAA act, turning the entire nation into a national defense zone (aka battle field), all they have to declare is "suspicious" and come along side and seize your vessel, arrest everyone on board and haul you off to some prison camp in some foreign country and hold you there till the end of time.

It wont matter if the vessel is registered in a country with no diplomatic or extradition agreements. NDAA overrides that...along with a bunch of other civil liberty laws.

I suggest studying the NDAA act and the added provisions slapped onto the extended Patriot Act as well. Don't assume everything is the way it was when you do not bother to read the things.

Ye been warned.

i heard about that. they dont have to even haul you off now. they can hold you in the usa in the one of 800 plus (and growing) detention camps in the conus. one in alaska can hold over 1 million people

The Barix boxes start @ less than $200, not bad for the compactness and power requirements (as already mentioned). They are dedicated units ... but, yes, you could certainly use an older computer ... but I would not run Windows, way too big and buggy .. the other caveats being size, vulnerability, and power drain ... better with an old laptop, but still problematic.

Because of the compactness of the Barix units, they are much easier to stick in a waterproof cabinet with the TX, and also require very little power. A desktop computer is wholly impractical to use in the situation we're describing, where the goal is to operate self-contained satellite stations via solar charged batteries.

At some point, as I get time, I'll try to run some numbers and come up with a basic parts list and expenses which might work.

"Cheap and quality?....well I suggest AM."

The problem, at least here, is that very few people relate to or listen to AM radio. In fact, even though everything I have out there, biz cards, posters, etc., all say Tune 1650 AM, people still try to tune it in on FM ... and since they can't get it there, they don't try anymore. IOW, if it isn't on FM they don't think it can be any good. Not very intelligent, but that's the apparent psychosis I have to deal with.

Generally attributed to the late, great Red Skelton: "Give the people what they want and they'll come out for it."

"The problem, at least here, is that very few people relate to or listen to AM radio. In fact, even though everything I have out there, biz cards, posters, etc., all say Tune 1650 AM, people still try to tune it in on FM"

Granted. I have even gone through that. What I have found however is the younger generations tend to lean more towards FM than the older generations.

And true most will tune the FM band than the AM band. With a little awareness campaign I think that little detail can be overcome.

The big issue would be the cost to set it all up, even with an AM system and the use of those Barix boxes. At almost 200 a pop, and using FM with its very short range, would require several systems, adding up real fast.

If the costs can be minimized its a fantastic concept. Some wheeling and dealing will have to be done to get permission to install all the TX points and arrange for their compensation (space rent) and use of any utility. The more TX points the more negotiating will have to be done. Depending upon the size of the area in question, that may take a good number of TX's and Barix boxes. And to be 100 percent assured of compliance to 250uV @ 3 meters, you will want to use certified transmitters capable of being synchronized and those will be up there around the same price as the Barix box, if not more.

Look forward to seeing the cost figures for say..a 10 system setup.

My group of friends have allowed me a couple of remote sites,non-overlapping,fed by a private internet stream. Works great providing you do some preventative programming so the computer auto boots itself and the programs needed to run. I have 2 remote sites,both fm,one am,same frequencies,running windows,playout with Zara 1.4 with sound solution. Its good I dont pay for anything except the transmitter facilities. Online for 2 years now...but forget any thoughts of the audio delays matching up,it wont happen with this method!

Heh-heh .. yep, Santa Catalina is "26 miles across the sea". The coastal ADIZ is patrolled by the Coast Guard and other military entities, and with a step-up process in motion due to the specific additional authority given the President in the 2012 NDAA.

"Don't assume everything is the way it was when you do not bother to read the things."

... So true, thanks for turning my head. 'Tho I've never been a big fan of the ACLU, they do have a point here.

IMO, just another case of fear-based politics eating away at the foundation of our freedoms because we have lost our enduring moral compass and would rather wallow in a world of who has the coolest widescreen TV, or the sleekest car, or who did what to whom in the entertainment world, than to face reality.

I say, "Take a fast ... stop looking at those things long enough to examine yourself and re-evaluate what's important before it's gone, wasting millions of lives given to have it."

It's not 'the government's fault' ... it's ours. It might appear 'apathetic', but I believe that's the wrong word if we are actually feeling too frightened and overwhelmed by the largeness imposed upon us by media manipulation. We have to, individually and corporately, admit our brokenness before we can take even a baby-step toward modern restoration.

I think any endeavor we try, be it Part 15 Radio, or participating in local government, or volunteering for community activities, or (fill in the blank), provided we do some research into it so that we can apply it well, is not only going to be worthwhile to the community, but you might even get some satisfaction and have some fun.

I can't know everything (simply because 'everything' cannot be known), and I'll continue to make mistakes, but I can operate under what I believe to be good and true, and if I can't perform miracles in national politics, I can find out enough to make a start right here at home, and, for me anyway, that with prayer, meditation, and fasting first ... then rise up and hit the airwaves, even if it only goes a mile 😉

"...but forget any thoughts of the audio delays matching up,it wont happen with this method!"

Why would there be differences in delays if the system is closed. We're not using the Internet. Could there be so much slop in the tolerances of components? Just one base station sending the signal to equidistant (even that wouldn't have to be absolute at such short distances) transmitters. Where are the differences in delays going to happen?

Ken N....But yes I am using the internet. Network to audio will be delayed differently with different computers,even if identical,their processors and timings wont ever match up,try it,I HAVE.If you have an STL radio linked type system that feeds direct to the transmitter(ie-no computer)will come very close to syncing. Remember the time is changed by everything that the signal passes thru,even a radio signal in free space! I worked on a 300 site analog paging system back in the day,all radio links and delay modules at each site,High stability oscillators but before we had capability to sync them. Audio was rough at best in the overlap zones. An imperfect method back then,may be better with synced oscillators now but who can afford that for part15?
I survive by not having any overlaps. I have coverage zones!
