1 watt, TWO BLOCKS!!!!! oooooooooooooh man, are you misinformed. we had this conversation before. engineers posted threads, low-power broadcasters posted threads, all stating that low-power AM at 100MW with an audio processor, has no problem getting 3 to 5 miles!!!. and when you hook that up to the internet, well, sell spots to the local merchants. and for the internet, there are various ways to make some bucks. one person, I can't mention names, built his 100MW station up to such a degree, that he sold it for $10,000. It can be done and It has been done.

Yes, a good 100mw transmitter costing around $1000 can get out a mile or more with the proper antenna type and height and really good audio processing. However, in an urban environment, this is a tricky proposition. Perhaps with your transmitter and antenna on top of a very tall building (I believe they can not be more than about 3 feet apart), properly positioned, it's still a crap shoot. All the buildings in a city play hell with any transmission, especially Part 15 at 100mw
There used to be a "business opportunity" advertised in the Philadelphia newspapers from a company who would set up several Part 15 transmitters and antennas in an urban area (for $50,000 or more) to get you "on-the-air" without a license. I think they went out of business.
So, why not concentrate on your station? A combination of Part 15 and Internet would be interesting. Local over-the-air and international via the Internet. Some people are doing this quite successfully. Then, you'd have to have programming that would hold an audience, advertising, marketing and promotion that would help attract listeners and then a sales staff who would communicate the benefits of advertising on your "hybrid" station. A daunting task, to be sure, but not impossible.
So, the $64,000 Question (showing my age) is, "Why not start doing it instead of talking about it here?" When I was in college, I had an English professor who said, "If you want to write a book, do it. Don't tell everyone about your book before you write it because that will satiate your desire to write it." Four books later, I can assure you that this works. I imagine the same holds true with any endeavor. Don't talk about it, do it! Good luck!

There is one more important point, a very good ground!!! specifically one that is well salted. salt water sends a signal out further. but some FCC agents fround on water pipe grounds, some don't. but there they are all happy with a dirt ground with an 8ft rod. hey, It may be small, 2 miles in each direction, but that is all of south philly, river to river. and like I said, It's what you make It.
Let me give you the hard cold urban realities. 100 MW, + 3 ft. antenna + Add buildings = 1/10 mile, max, or barely the equivalent of a single city block at best. Stone cold reality. Make book on it. And that is even questionable with today’s AM radios. I don’t care if you say you live on a salt mine as big as Salt Lake City. Urban Core infrastructure, 1/10 mile max. And any I-buzz within 30 KHz, kiss that goodbye. Now you may return to your own previously uninterrupted reality.
you forgot one thing sam, FCC regulations, 9ft antenna is legal. the mast can be 200ft high, but the attenna, by regulations, can be 9ft. do the math. 200ft plus 9ft, not bad hight. people need to study part 15 broadcasting rules.
AM requires a ground wave. It’s not like FM. For those who entertain mast/height for AM, the higher your mast the further disconnect from the ground system. You have thought about a ground system haven’t you? You did price out copper yes? Like maybe, 16 Symmetrical copper radials? No? Ok. let me start this again with the recalculated hard cold urban realities. 100 MW, + 9 ft. antenna + Add buildings = 1/9 mile, max, or barely the equivalent of a single city block at best. Stone cold reality. Make book on it. And that is even questionable with today’s AM radios. I don’t care if you say you live on a salt mine as big as Yucca Flats. Urban Core infrastructure, 1/9 mile max. And any I-buzz within 30 KHz, kiss that goodbye. Now, once again we return to your own previously uninterrupted reality.

Uh, at 200 ft. with a 9-foot stick ... will it be lit, too, with a Christmas star and a red light for obstruction or will the FAA just waive that since you'll be well salted?

I did try it, I bought a cheap, very, very cheap hobby kit, and guess what!!! without a good ground, I reached 1/2 mile. just think of the possiblities with the hamilton rangemaster 1000, plus an Inovonics processor and an 8ft ground!!!
Flash! Instant update! An Inovonics processor should give you just about the broadcast quality of an original, deluxe, mint condition, CBS Volumax Distortomax, for that genuine CB quality. Ever listen to turnpike radio? Happy motoring.
It's the low salt substitute. Remember rule 1 of your broadcast handbook, you have to attempt to limit excessive high blood pressure, and all unnecessary chemical exposures when attempting a silly feudal effort.
Rule 2 of the broadcast handbook, never rule something a feudal effort If you've never tried or have any kind of experience with It. what is absolutly amazing is all of the low power broadcasters that I've talked to who have these stations operating, and are getting 2 to 5 miles, you know more than they. hummmmmmmm.

Rule #3 of the Broadcast Handbook: Know what the heck you, as a 100mw radio station ... "planner" are talking about: I've done some research in pictures to help you out, Dennis. Note: This isn't, certainly, Philadelphia ... it's a little burg in New Hampshire.
Here's slide one for 100mw at 1700 AM (no interference there, certainly) Radio Derry (no call letters needed.)
http://radioderry.com/_wsn/page2.html
Note the "distance bar" in the upper right hand corner. Not in miles ... but in feet. Measure the 1800 ft. "main lobe" (the inner circle for those following along,) and you tell us how you get "primary" coverage of 3-5 miles. It's not even a mile, as we've been trying to tell you ... and, again, this isn't Philly.
Slide #2, please: Thank you. Here is a coverage map of WDER Radio 1320 ... a 1,000 watt blowtorch in Derry, New Hampshire. I might add that at this pattern (nighttime) the "theoretical pattern" requires FOUR TOWERS and notice the distance in the red circle ... again, the "primary signal" coverage of this pattern:
http://radio-locator.com/cgi-bin/pat?call=WDER&service=AM&status=L&hours=N
That MIGHT be 5 miles ... maybe, of "primary coverage" ... and directional at that.
Now, if we could return to slide #2 in our presentation, please ....
http://radio-locator.com/cgi-bin/pat?call=WDER&service=AM&status=L&hours=N
Note that the farther from the tower site (with four towers,) the signal is "fringe" at best and goes all of ... 10 miles.
Incidentally, this station broadcasts at 10,000 watts day from a three tower directional. The pattern is 20 miles through to the fringe area. The primary coverage is about 15 miles.
I have a dozen other examples if you need them, since, obviously, you've done no research on the matter. I also can fill you in on the Ramsey xmtr and any other gear you need. Drop the Innovonics, unless you're going into CB or a traffic TIS. Doo wop will sound like Bee Poop.
Why not save yourself time, money and needless effort. Go to the Internet. A lot cheaper and get some reach with your own brand of radio, seriously. You'll be glad you did...
200 ft. on a mast with a 9ft stick, huh? For AM? Good luck. May your dream come true.

Are you kidding? I’ve got transmitters here that that will put a signal over your house like a torrential rain cloud, all the way from here in Gladwyne. And if it didn’t upset OGL again so much, I’d turn it on for a solar day and let you hear Hy Lit Radio on the open frequency of my choice.

Feudal? It evokes images of serfs and vassals. I would go into greater detail, but it would probably be futile. Again, why not just do it (get your station on-the-air) rather than talk about it.

WOW! I Love slide shows. What time is the next feature presentation? I want to get some popcorn ready, lightly salted.

Re: JERRY BLAVAT AND RON JOSEPH (RJ) DID A COMMENDABLE JOB HOSTING MOVIE DOCUMEN
OK, look, Dennis ... this is about calming down and thinking straight for a change, despite the fun we've had here, ok? Believe it or not, we're trying to help you ... and as you calm down, things tend to get a little clearer. No one wants to interrupt your dream. Just be realistic ... and then do it. That simple.
First: "There is a statement on the FCC website that says that Part 15 transmitters only get 500 foot of range. We get asked regularly how transmitters such as the AM1000 can legally get 1-2 miles range in view of this statement."
Second: On the Rangemaster website itself, (you know where it is,) in no testimonial, despite your claim, does it say anything about 20 miles of coverage. Most are 1-2 miles at best, 3 miles in a vehicle (cars/trucks would, naturally, receive better.) Again, "your mileage may vary," as you were just told. And that doesn't mean "crystal clear." This thing isn't an Optimod equipped 1kw linear CB transmitter. It's a limited range 100mw box.
Third: Why AM? You know how crappy AM sounds and with these limitations, you still have crappy AM sound no matter what. Why not go FM? Or better, 128k or even 64k Internet and your coverage area is the entire planet? In stereo? For less than $100 a month? (Of course, licensing and royalties will vary on top of that monthly.)
That and a web site, and you're off to the races for a couple hundred bucks a month, 24/7. Get more listeners, pay a little more. Get sponsors cheap and do it right. Why get into this hassle with AM that so few listen to ... and especially as more than a hobby?
Hell, if you're gonna play hobbyist ... go FM. Most people know what that is, at least. Or ... go your own Internet route. It'll cost you a lot less equipment wise, anyway, than what you're looking to buy. Thanks for listening.
