Get Me On the Air!!!

So I am moving to a community of about 1500 people in Wisconsin near the Lakeshore... I ran a part 15 in Plymouth, WI with a Ramsy FM25B and got about 1/4 Mile of coverage with just a whip antenna. The apartment we are going to be renting has coax running up to a TV antenna on the roof. I'm almost positive this can't be done, but I wanted to be sure anyways... Can I connect the transmitter to the coax that runs up to the roof and utilize the TV antenna as my transmit antenna? will that get me ANY coverage at all? I doubt it very strongly, but I thought I'd at least ask. Also... what kind of range are people getting with that 100 MW EDM Transmitter. I am to understand that this particular transmitter is not quite legal, but I'm more concerned with my community than I am with some stiff from FCC headquaters stopping by our apartment to check out my cheezy setup.
Appreciate all the advice I can get.
Can't wait to get on the air!

Hi Bill,

Yes, it will most likely work as a transmit antenna. The VHF tv band is split between channels 6 and seven. This is where the FM band is located. Thus TV antennas are set to receive a wide range of frequencies, including FM.

This will not be a tremendously efficient setup, but it should work.

Some things to watch out for: The TV antenna is directional so a lot of your signal will go in one direction, and less in others. Not the best setup for broadcasting. The other thing is that there might be an amplifier or booster in the line to the antenna. This will block your outbound signal. Also make sure that the antenna system is properly grounded for lightning protection.

I would try it and see if it works. You have nothing to lose. You won't hurt your transmitter because of a bad antenna match. I usually run my FM25A without any antenna (I listen to movie audio on a walkman and don't need any range) so I don't bother the family with noise.

You might consider building a J-pole antenna. My son has one we built using 300 ohm twin line. He taped it to his window and it gives a couple of blocks range.

Let us know what happens.

I don't know anything about the EDM unit so I will defer to the expertise of others.

Neil:
Thanks so much. I'm still contemplating whether or not to just go AM. The more I talk to Jake Thomas and he brags about how he'll be able to get a mile of range legally with the help of Antenna guy Carl, and that I could have it all done for under $500 and it'd all be legal, I may just go that route. Getting pretty excited about this whole setup. I have automation, I'll have an oldies music library, I've got a RAMKO broadcast board, a Sennheizer broadcast mic on a boom, all I really need is the transmitter and the help of Antenna Guy Carl! Gotta' get some free news feed that can be automatically downloaded from the web and aired back around the top of the hour, and find the time to cut local news, and I think I'll probably be able to get a few people to listen. With oldies, some news, and running some local church services throughout the week, I think I can bring community radio back to Cedar Gove, WI.

Re:Get Me On the Air!!!Heres how.

I would not count on the apartment antenna as a broadcast antenna, By the time the signal got to the antenna though all the splitters and amps, there would be nothing left to transmit. Remember you most likely have a tap behind your TV port which pads your signal down, then a few splitters a system amp. many amps have a FM trap switch built in if its on that’s where your signal stops, then there is the antenna which may design to trap FM stations to prevent overload to televisions.
The best way to set up your station is with an EDM 100 transmitter and a dipole antenna, depending on how high you are you can expect a mile plus coverage. I have used a dipole inside with fair results on the third floor, You can also get great results hanging it out a window. I know one guy in Arizona who serves a community of 25,000 with a single EDM 100 and a dipole. His station is not part 15 but very close, it is true full service community radio station complete with sports and radio drama from the same High School.

Returning radio to the people one station at a time.

Bill,

Your welcome. I hope I helped. I like part15 AM. You sound serious about real broadcasting and that is great. Obviously you want to maximize your range. AM can be good and it can be bad. I only intend to broadcast around my 1/2 acre property and for my own use. I am my most loyal (and probably only) listener! Therefore, other than the technical satisfaction, range is not my concern.

That being said, here are some things to consider. I do not mean to discourage you, but rather point out some obstacles. If you are renting, you may have a problem installing an outdoor antenna. Carl's antenna design (SSTRAN site) is very well done and according to what I have read works well. Could this be installed at your rental site? When I rented, I struck a deal with the landlord...in exchange for some painting and wiring, I was allowed to mount an antenna on the roof (a dipole for short wave listening). That was many years ago and I know things have changed...landlords seem to be skittish about liability.

Another problem that I have is electrical interference to AM reception. I cannot listen to AM in my house (other than my own transmitter signal) because of interference from light dimmers, flourescent lights, etc. I suspect that this is the case for many of your potential listeners. This can really limit your range. In my case, signals that are great in my driveway are not usable inside my house. Yes, I could eliminate the sources, but I doubt that the average listener will do that.

I really enjoy using part 15 AM and it suits my needs well. Just do your homework. Read this board, other boards, and check out the Rangemaster site. It has some good tips and explainations.

Neil is quite right.....these things do indeed happen.......so I will say a few things........(please guys, try and cope with the typing; it is not me, it is just webtv and posting, cause they don't get along).........
Generally, If you CAN put an AM antenna on a roof of an apartment building, and we are looking at a very unusual ground system, the results are generally pretty good.......Considering that there are a large group of people living in a very small area, and the signal does travel around a mile or much more even with this installation, the apartment building and the buildings surrounding it receive a very good signal. Remember, a good quiet frequency is important, and I like to remind people that not everyone has an expanded band radio available.......................I came up with a somewhat of a solution some time ago by mistake: and I can't get into antenna lengths because of space and time constraints, but in truth, we operate with very very small antennas.........I've made it a bit smaller by installing a type of top hat that makes the antenna a legal length, but in doing so, it is kind of directional as well......so as the antenna itself radiates omni-directionally, some of the signal (well, about 60% of it) does concentrate in a 90 degree direction......this antenna works well for someone who has a deck and nothing else to mount it on......and needs to shoot thier signal in another direction.........Generally, everyone beneath the antenna will receive the signal. While true that electrical devices will work against any AM signal, the simple fact that you have an originating signal right there should give you a strong signal in your apartment complex, and to buildings very close to yours....Regular houses should receive signal within a 1 mile area and cars should receive it a bit further than that.
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
I do think the Rangemaster is a great tx; I also think the Rangemaster is vastly overpriced and out of the range of the average consumer. Therefore, I do endorse the sstran as the best sounding, best ranging transmitter at about the best price that can buy an AM transmitter.
The Rangemaster has skills the sstran does not; that is that you can use several of them in different locations to elongate your signal. Our antenna doesn't work with the Rangemaster; it uses a standard CB type antenna, which costs about 80 bucks at Radio Shack....................For people like Maurice that has a very large installation, the Rangemaster is killer and in fact, kind of needed. I understand Maurice may use sstrans soon to fill in blank spots, but that is another issue....................
But if you consider AM, I would look very closely at SSTRAN because it is simply the most affordable and best sounding tx money can buy.
I went on record on this years ago and I stand by what I said.

Carl,

Thanks for adding to what I said. Again, I do not mean to discourage Bill and your words are encouraging. I have not achieved the field strength that you are talking about. I don't have an outdoor transmit antenna. Was going to put one up last week, but an old back injury flared up and prevented that. May not get it done until Spring. The top hat sounds like a good idea.

I also did not necessarily intend to steer Bill to the Rangemaster unit, just to the website which has some nice technical tips.

I also have the SSTRAN AMT3000 and am very pleased with it. It is a fine product and is reasonably priced.

Bill, I tried to post a reply to Radiobrandy's post to you about the TV antenna, but I must have punched the wrong key and it got lost. Radiobrandy is right. I did not think about the fact that this could be a shared antenna. Definitely do not send a signal into that system. You will most likely interfere with TV reception and get banned forever from transmitting in you building. I know from experience (ham radio...not part15) that TV interference (TVI) problems are not solved by discussing the legality of your transmitter. I have had only one TVI complaint in 30 years of operating and it was due to a defective connector on an antenna amplifier at my neighbors house. I fixed it for him, TVI gone, and a better picture than ever. I hear that not all TVI scenes end as happily. Point is...I was operating a licensed station in a legal manner. The only thing that mattered was my neighbor had interference.

If you use your own antenna for FM or AM, the chances of TVI are minimal and nothing to worry in advance about. You will probably never have to deal with it.

Neil
 
Re: to Carl and Bill ... afterthought

Bill,

Just wanted to add to my last post that I was running 280 watts PEP SSB into a tuned antenna at 7 MHz. and my neighbor was in the major lobe about 300 feet away. Once his problem was fixed, no problems with anyone. I also ran a 2 meter repeater with 350 watts ERP on 144.67 MHz. with no problems. Point being that the part 15 power levels are very unlikely to cause trouble. Just don't hook it into a CATV (community antenna tv) system.

Re: to Carl and Bill ... afterthought

A Few Corrections:

Alright, let's re-think this whole EDM to a TV antenna thing. I'm not moving to an apartment "building"... I'm moving into an upper flat. The wire comes from the roof, through the wall, and into the closet where I want to set up the makeshift "studio". Like I told Jake today... there are no splitters anywhere, just a line straight off the roof, and it's about 50' of coax from antenna to our upper flat. With that in mind, would this scenario work with that EDM transmitter, or am I still better off building an antenna?

My next issue: processing - does the EDM transmitter have any compression/limiting built into it, or do I buy a processor to put between the trusty RAMKO board and the EDM Transmitter?

that EDM transmitter is not "technically" Part 15, right? to legally be part 15, your signal can't travel more than 1/4 mile, correct? If it does in the town of Cedar Grove, Wisconsin (zip 53013) is there anybody I should be looking out for that might enjoy snitching? How do you know?

What a great board, guys. It's great to talk shop with guys that really know their stuff. I appreciate all of the advice a whole lot!

You are still better with your own antenna, The Coax is most
likely old(weathered)RG 59 or 6, The Antenna itself might be
300 ohm with balun. You will never get a good SWR which could
burn up the final on the EDM.

The EDM does not have any processing built in.

First thing I would never give out your location on the internet,
the only complaints the FCC really cares about are from licensed
broadcasters, it's best to keep a low profile with people you don't
really know: you never know when some pin head looking to get even will
try to turn you in. Just till them its a legal part 15 station. You like
many can't really put up a outside antenna, the EDM makes up for that with
a little extra power.
Go with a dipole on FM and go for broke and go AM too with a Sstran and a
antenna from Carl. And have the best of both worlds!
Note: The new automation section is up on the Radio Brandy web site,
It's a work in progress.

You are welcome as well......I will say that an inside antenna is indeed cool if you are broadcasting for yourself.......in fact, just placing the wire antenna outside the window will most likely cover your yard depending on how large your prarie is, but you don't need to install my antenna high in the air and it is not back breaking work either!....There is a lot of people who love it high up and you really can't change these guys minds; it is doable, sure.......but when asked I say keep it on the ground where, if you need to you can attend to it. For some reason people think "high-up" is great for AM, but that is not the way AM works........not for nothing but I've had reports from about 30 of my 50 customers this year and all had something "else" to say but all of it pretty positive.........I appreciate your comments.

AT the risk of loosing a potential customer (hey, I'm used to it!!), here is the scoop:
1. I belive you own the EDM 100: I own the same unit. It does not require a processor in your case because you are using a mixing board and I do the same thing....It puts out what you put into it.
2. The EDM really does not require any more antenna than the thin wire supplied with it (virtually the same similar type of wire issued with the sstran without the ground, used for very local broadcasting).
3. To reduce the power of the EDM for legal use, coax is good. I would advise a very inefficient antenna, because you really will not need anything special at all.
I went on record on here as saying it is the best FM tx money can buy for it's price; actually it is a bit better and I feel about it as I feel about the sstran for AM.

The EDM 100 is a pretty powerful unit and it is easy to have it become illegal even more (that is, get noticed) by operating with a dipole. Now, I do know a guy doing this and at a very high position in the sky.......that is his biz and I applaud him for having the b##ls to do it................For me (because my opinion above reflects my tests), the EDM didn't require processing, but it could be my studio makes up for it; I'm not sure on that......EDM sounds like your favorite FM station, like the sstran sounds for me.............
Basically, the coverage for the sstran with my antenna, and the EDM with the wire is pretty damn close; the difference is you will get the FM drift with EDM if you don't have a clear frequency, and most places don't have one.....the AM is kind of better in this case because the likelyhood of finding a clear frequency is better, so at the end of your contour, you will most likely get AM static, but you may get a much better pattern with AM over FM at these powers......I WILL say that customers using my antenna at a high height do report large contours, all of which are very legal, and again, unless you interfere with a commercial station, you will never hear about how strong your signal is...with FM it is different; everyone tends to look at this. If you have 5 miles of signal on FM, you will definately be picked off at being a pirate, even though you are only using 100mW......so the basic thinking here is use AM for a longer, far reaching signal, and FM for something very local for your neighbors......just my penny of thought for today!!.....Carl<P ID="signature">______________

I just have to say I love your idea.. I love community radio, and Im doing my best here in Lilburn Ga. Im using a transmitter no one likes, a Ramsey,
one of those stations in a box, kinda of transmitters. But great range, only with a whip antenna. Keep it up boy, and man what a board you have, only wish I could afford a real radio board, A radio shack mixer does my job just fine.

Carl:
We are moving into an upper flat, and I don't think I'd have a way to put in a ground screen on the landlords property to do AM, otherwise I would. Do you think even a mile of coverage with the EDM could potentially get me in trouble? Couldn't I just use a super crappy transmit antenna? I still do not believe you can get more than 1/2 mile with a 100MW transmitter... but the only reason I say that is because I barely got 1/4 mi with the old RAMSEY Transmitter I had 2 years ago.

Re: to Carl and Bill . afterthought

I'm not Carl (nor do I play him on TV) <G>, but a ground screen for a Part 15 AM transmitter isn't hard to arrange. You could run insulated wires around the baseboards (and under carpets, if desired) and connect them to the transmitter's ground terminal. If you have copper water pipes in your flat, connect them as well. -- JasonW

Re: to Carl and Bill . afterthought

Carl:
What if I don't have copper water pipes in our flat? We're forced air, not hydronic... but water pipes that go to the sink, dishwasher, washer & Dryer are all copper. Would that do the trick?
what kind of coverage / range could one expect to get with a ground screen setup if I did just drag some insulated wires around the apartment? aren't we talking a whole lot of wires to make up a decent ground screen? Would there be so many wires that my wife would consider divorcing me because our kids hair won't quit standing up?
