As a retired professional broadcaster of 35 years including program director of WTIC AM, FM, Hartford, KFMB AM, FM, San Diego, K101, San Francisco, KMGX, Portland, Or, KRPM, Seattle, KYUU/X100, San Francisco and several medium markets as a PD, DJ, CE and consultant, I have never seen a better bang for the buck anywhere in broadcast than the Range-Master 1000, or a more enthusiastic and professional group than it's owners, and manufacturer. Our station and sites have been inspected and certified by the FCC with perfect records. I would tell anyone thinking of operating as a hobby, church, or fully commercial station such as we (BE Audio Vault, Pacific Recorders BMX boards, CRL, Dolby, PR Multimax and fully licensed STL's) that you will save money and get optimum results with Hamilton's Range-Master 1000 AM transmitters. Attempts to operate on FM or with any transmitter I know of other than Range-Master may expose you to penalties ranging up to 5 years, short range, frustration, and hindsight that Hamilton is the only choice. Our first transmitter has been operating with no maintenance on a 60' mast 250' above average terrain, with winters in the snow and summers above 100 degrees for 3 years. Nuff said?

I purchased the Rangemaster to operate a little community radio station out of my real estate office.  I was in commercial radio off and on for over 25 years.  In the old days I used to think automation and other advances would  free us up from cueing records and dealing with carts.  I was naive enough to think that when we got the automation, we'd have more time to develop local news and useable information for our little town.  Of course it didn't work out like that at all.  Instead, owners of several stations could use a smaller number of people to work 4 or 5 stations.  After all....now you could do a 4 hour shift in 20 minutes. 

The Rangemaster is working great!  I am using an Inovonics 222 processor with it.  My antenna is about 25 ft....mounted on the top of my office.  I'm getting mixed results at a variety of ranges.  We come in pretty good ...up to about a mile.  However, car radio reception is pretty good in some areas 3-4 miles away.  I am very pleased with the Rangemaster!  We've been on the air since the middle of January (2007) and haven't had any complaints from the local 1000W AM in town (they're really broadcasting from another town 35 miles away with an STL).  We broadcast local news, weather, real estate info, local history, meetings, etc.  I have one paid sponsor.  I hope to get a few more soon.  I'm using the DRS 2006 automation system and it's working great.  It does have some limitations....by hey.......it only cost $69 online! 

I had a few difficulties getting my Inovonics 222 set up.  The transmitter was always being overdriven.   Keith sent me an attenuater to put between the processor and transmitter.  It works great now.

Life may throw you a few curves........but not the Hamilton AM1000 Transmitter.  It was snowed on, rained on.........we had a wind storm......etc.  It never blinked.  I hope to order another AM1000 by late summer. 

I've had absolutely no concern voiced over the station (and I'm amazed at that!) and have had no contact with the FCC.  Thank you Keith Hamilton.....for creating a great little transmitter!

My name is Tony DeNicola, a professional radio engineer and owner of a AM 1000 transmitter operating on 1710 in Edison, NJ.  I also own and operate my licensed 1KW AM station in VA and work for Clear Channel Radio in New Jersey. I have to say that this transmitter stands right up to the sound of a Harris or Nautel  when you use professional audio equipment like a CRL, or Optimod.  I must say I’m very impressed with the coverage of the signal with such a low output power. The high Q gain of the output circuit really is incredible into a CB whip. My AM 1000 is mounted on my patio wood fence and is 10 ft off the ground and gets out 3 miles with great sounding audio using a Compellor and CRL compressor along with c CRL NRSC filter. I must give my thanks to radio engineer and also  owner of a AM 1000 to Dave McCrork who told me about Keith’s AM 1000. After I heard his station on 1620 in PA I was sold and contacted Keith Hamilton to purchase one.  I plan to broadcast Adult Standards along with Big Band music and news 24/7 by the summer of 2006 once I install the transmitter in my back yard away from the house on a 50 ft. telescopic mast. Thanks Keith for making it possible to broadcast to my local community legally.  I have pictures on my website.

By the way, my Home School class is now programming  weeknights and weekends and are enjoying the world of broadcasting as I have set up a studio. The Rangemaster is the finest sounding LPAM part 15 transmitter I have ever experienced. Thank you for all your help in making this happen for the students on our budget. The chief engineer at our cluster of commercial broadcast stations where I work was amazed at the range and audio output and even more so, after installing an Inovonics 222 in the audio chain

My station, RadioKVMW, AM 1670, is on the air. Thank you for all your help. I can receive my station on my car radio at a distant of two miles very good. The extended range is from 3 to 4 miles depending on the weather conditions.The technician who is installing my equipment on his off time has  been unable to install my inovonics 222. I expect to get even better reception when he is finished. The rangemaster transmitter is ever thing you said and more. I have it on a 40ft mast. My house is on a mountain(hill too those who lives in the real mountains) on the edge of town. Thanks again for all your help and the great rangemaster transmitter.

Keith, an update on my radio station since I first wrote you how satisfied I was with your transmitter. Using a boom-box with an antenna I pick up my radio in a brick office building 2 miles from the transmitters. I found that the boom-box was better than the Radio Shack antenna. Thanks again

The RangeMaster is the best Part 15 transmitter I know of.  On a 25 ft office building roof with a 5ft poll, a single transmitter gave us a distance of nearly 2 miles!  Audio was excellent.  Getting ready to put a community radio station on the air using multiple transmitter locations.

The performance, reliability, and audio quality of the AM 1000 is amazing.  Our audio chain consists of an Aphex Compellor 320A and an Omnia 3AM.  Our audio chain coupled with the AM 1000 produces a sound so good that you can't tell the difference in audio quality between us and our local small market 25Kw AM Radio Station.  You could pay thousands more and only get half the audio quality of the AM 1000. In our opinion the AM 1000 is absolutely the BEST transmitter available.

As an owner of the Rangemaster outdoor transmitter, I can genuinely vouch for its professional design and performance without hesitation. My Rangemaster has been performing flawlessly for several years and under many adverse weather conditions here in the north east. Its rock-solid signal can be compared to units costing thousands of dollars and my coverage area has far exceeded all of my expectations. While I would have been content with a 1-2 mile range, I have received telephone calls and e-mail from listeners at distances as 10 miles or more from our studios. I consider the Rangemaster the be the Cadillac of low-power transmitters on the market today and would highly recommend it to any serious broadcast enthusiasts.

NOTE: THIS NEXT PERSON BOUGHT AN AM1000EC INDOOR UNIT WHICH GOES INDOORS, IT DOESN'T GET THE RANGE AS THE OUTDOOR UNIT.

We used the RangeMaster at our Church for a drive-through Christmas Play so people could stay in the warmth of their cars yet hear messages we transmitted throughout the performance. The RangeMaster worked beautifully and was easy to set up per the enclosed instructions. Sound on the radio was as good as a radio station within the half mile radius. The people at RangeMaster were courteous, knowledgeable, and easy to work with. I highly recommend this unit for similar uses.

I used 5 am 1000 range masters, for my lpam in nv, they were on a billboard 60 feet high, they more than covered the town 4 miles by 3 miles, and my station sounded like a 1kw these are the best xmtr's you can buy, and they are worth every penny, I know, I have set up stations all over the u.s.

I read the specs on the website and really doubted how well it would apply to a large metropolitan city.  I'm happy to say that my Rangemaster is exceeding all expectations.  On a stick at about 40 feet, I'm getting a good listenable signal in the car about 3 miles.  It sounds great!

Our school has been using RangeMaster transmitters for our student radio station for some time. The quality is exceptional in every important area. The RangeMaster has the best coverage, the best sound, the best reliability and, most importantly, the best company to stand behind it. The syncing feature has given us the ability to serve specific areas with professional results. Keith, we’re real believers in your product!

I'm a novice who was able to set up the AM1000 Rangemaster quickly and easily. Keith has been very helpful and gives good support; he is committed to providing excellent service. The AM1000 Rangemaster transmitter is working great with 1.5 to 2 miles in a densely populated part of the city. The sound is strong and clear and I'm very happy with the performance, stability and quality of the unit. I highly recommend the RangeMaster.

Hi Keith,

Today we went for a family drive to see how far we would be able to receive our signal.

I have it mounted on a rohn 25 type of tower at 25 feet with the ground strap of about 6 inches clamped onto the tower. Useable range in the car, ie, pleasant to listen to is an easy 2 miles - depending on electrical noise from the electrical utilities. At about 5 miles it was getting unpleasant to listen to but still understandable.

At 10 miles you could tell it was still there, but not understandable. At that point I pulled out my Radio Shack DX440 receiver and Kiwa Pocket Loop antenna. Was able to pull in the signal again and easy to understand. If I was going to listen at that range I would put up a long wire or use a better loop antenna - for instance the Kiwa Medium Wave air core balanced loop.

In other words it was getting to be a dx signal. We ran out of road at 14 miles and at that point we could tell it was there on the car stereo - barely, and with the portable receiver with loop antenna it was back up to understandable but not to pleasant to listen to.

We had been running the audio a little on the low side due to some of our test programming not being equalized to the same audio levels.

So the last few days we have been turning up the audio input until it starts to get a little distortion and then backing it down just a little bit.

The difference was quite noticeable, especially around town at the 2 mile range in that it cut thru the electrical noise alot better. I would estimate an increase in useable range by 1/3 to 1/2more by getting the average modulation higher. Actually the difference was enough that we were raising our eyebrows in surprise. So down the road a decent processor will be installed so we can take advantage of the

+125% modulation that the RangeMaster will transmit.

As far as audio quality, the transmitter is quite hi fi, so it will depend on your receiver as far as how wide its IF filters are for how good of a sound you will get. With the average wide as a barn door consumer AM receiver with decent speakers it will give a signal comparable to an FM.

I've been using the Rangemaster Transmitter for the past three years for my Part 15 station and couldn't be more satisfied with it's performance.

It is an excellent, reliable unit.

I live in a condo complex in a very congested area of New Jersey. The town I'm in has warehouses other complexes and lots of overhead electrical wires. My transmitter is on the second floor terrace of a five story building. Even with the height restrictions and the obstructions I get almost 1 mile range and the audio quality is excellent If you are planning to start a Part 15 station, I would strongly recommend the Rangemaster, you won't regret it!

The Rangemaster1000 has proven to me to be the most effective Part 15 type accepted AM transmitter available on the market today. The range is phenomenal and the sound quality fantastic. The service after the sale is top notch. All our questions were answered fast and accurately. The best product, and the best people!

Thanks!

The Rangemaster is absolutely the best low-power transmitter on the market today. I have owned a Rangemaster for over 5 years. It is in my attic and I am currently getting up to 5 miles reception on my car radio. This is not diameter but one way. Be sure to keep the antenna as straight as possible, tight with no slack. I occasionally experience distance reception at 8 miles. I currently use the station as a community radio station playing music, news, and public service announcements along with live dee jaying. The transmitter is connected to my PC which has radio automation software on it. I also have a mixer and CD player connected. The station is 24 hrs a day. The audio quality is excellent and is equal to or better than most AM radio stations in the area. In fact, the audio quality of the Rangemaster is better than most AM radio stations within the first mile. Except for having a burned out transformer (caused by the extreme Alabama heat in the attic during summer months), the Rangemaster has been up and running the entire period of ownership.

Kudos to Keith Hamilton.

As a commercial radio DJ, I’ve always had limitations as to what I can do and say over the airwaves. Not anymore thanks to the RangeMaster LPAM. We have about a 2 mile radius around my house that can clearly hear the antics and goings on at my Radio ranch. Our RangeMaster’s signal is clean, and the Bass response is like nothing I’ve ever heard on the AM dial. We’ve been running the RangeMaster for many years and with all the high winds, bad weather and extreme heat here in Las Vegas, it just keeps kicking out the hits. What transmits in Vegas keeps transmitting in Vegas thanks to the RangeMaster.

I used the Hamilton Rangemaster transmitter... I had 4 of them, with the main here in a small town of about 6,000 homes. the station at 60 foot, covered the town and then some. in another part of the county, I had another transmitter on top of a motel, audio connected by telephone line, and eq'ed for frequency and balance. that transmitter covered the island in witch it was in, and overlapped the first town's signal without a problem.

The audio quality of the Hamilton is professional quality. can't get any closer other than fm... the audio quality, when set up correctly from your audio source, should sound as equal to big stations. there is no difference. 600 ohm input to the Rangemaster, is the same as the 50,000 watt transmitters.
The range, with good grounding, and height of the transmitter will, yield a harvest of signal output. the best way I can relay this, and this is where people have a hard time understanding..... most transmitters are tuned for the highest output within the FCC laws.... this is the same except, with this transmitter, it is best optimized to the environment in which it is installed, therefore transmitting a signal that is surpassing any part 15 transmitter that is tunable. this, itself, makes the Rangemaster the king of the air.

Keith, I think you've done a great job with your Rangemaster and made it possible for old pros like myself to get into hobby broadcasting without being forced to buy junk. Just because we broadcast as a hobby, doesn't mean we no longer desire using professional equipment!

Of course the most important thing when installing any AM antenna is the ground system. With a properly installed Rangemaster the performance for me has been both impressive and very reliable. Mounted outside on my roof on a tripod, exposed to all the nasty weather Indiana can throw at it, this unit has functioned non-stop since installed. Despite local lightning strikes and below zero weather, this transmitter marches along like a little grey soldier asking nothing more than clean 12v DC and a good antenna to shoot with! If I had to do this purchase over again, would I? You betcha!

Hi Keith! Just wanted to tell you how great your transmitters are. I've put several in for my customers and they love them. The range and audio quality are exceptional and I want to thank you for your great products.

I highly recommend them for anyone who's serious about part 15 broadcasting!

Thanks again!

I use the Rangemaster to play music that just isn't heard on the radio anymore. My listeners are older folks around my immediate neighborhood who miss hearing the old "adult standards". Also often carry "Classic Heartland" out of Branson MO.  I have the transmitter on when I am home and on weekends.

The Audio fidelity is quite acceptable. Range is about a mile and a half on a car radio. Distant fluttering traces of signal can be heard as far away as five miles. It continues to surprise me that 100 mw. can do that. Table top or bedside radios pick it up very solidly for a couple of blocks in all directions, and that's the neighborhood I'm trying to reach.

I use an Orban gated compressor/limiter to give the signal extra punch. The transmitter is mounted atop a 25 foot pole beside the house with the ground wire dropping directly to a buried 8 foot rod. The transmitter tunes up well with that arrangement and runs happily at 100 mw.

It's just a lot of fun.

Dear Keith,

Just wanted to drop a quick note about your AM1000 Rangemaster we purchased this past winter. This was the second transmitter we bought from you (the first was for a college radio station, which is on the air and has a whole radio course built around their low power am station which they love, and quite frankly sounds as good as the full-power commercial stations in the area). Our latest application involved setting up the Rangemaster to broadcast christmas music for a community-funded lighting display show for the holidays. People were able to drive through the displays and tune into holiday music / updates as they drove around in the comfort of their vehicles. Coverage was excellent over alarge city park, and we easily mounted the unit on top of a shelter house. Easy installation, quality - durable manufacturing, and it even survived the minus zero weather... :) Thanks for the great product, and I would definitely recommend anyone looking for an LPAM to buy this unit. You will be satisfied.

Best,

Keith,

I'm using the innovonics 222. Range is 1-3 miles. Still have some work to do. I'm programming Country Music. The transmitter is up about 45 feet.Plan to go higher on my tower. Audio on transmitter is great.

I wish we could put out more power. I like the 1000 rangemaster. I would purchase another one.

Our local talk radio station left our town and I got picked to come up with a solution. I did a lot of research on part15 and found that everyone recommends the Rangemaster. I have never messed with any radio equipment before the Rangemaster. After receiving it, and watching the included DVD, I had this transmitter up and running within a few hours. The transmitter is up on top of my building about 30 feet high. It really sounds great. We are getting great range. On a good day we can hear the station about 8 miles away, but the average is about 3 to 4 miles on a good signal and we live in an area with lots of hills and mountains. After seeing how great this transmitter works, we ordered another one for the next town in our area and it is now running great and now everyone is happy. The range with the ease of setup (even for me) makes this the best transmitter out there,

Thanks Keith for everything

We tested other transmitters on the market before choosing the Rangemaster. There's really no comparison, as the Rangemaster gives far superior range and sound quality. Additionally, our broadcasting engineer raves over it's superior construction and design. Way to go Keith!

The Hamilton AM transmitter has the best sounding audio of any low power AM transmitter on the market today. In addition the broadcast range clearly surpasses that of any part 15 AM kit on the market. This unit is FCC type certified for part 15 AM applications. Knowing the unit has the FCC seal of approval allows me to broadcast hassle free with little worry about a problem with the FCC.

Dear Keith,

I just wanted to write to let you know how pleased I am with my AM1000 transmitter. Its’ quality and durability have certainly exceeded my expectations.

I purchased the unit from you two years ago for my neighborhood broadcasting station after having unsatisfactory results with a competitor’s “assemble-it-yourself” kit transmitter. The AM1000 was easy to set up and tune, and after two years of continuous operation, still performs flawlessly. I would definitely recommend this unit to anyone who is looking for a part-15 AM transmitter with superior range, sound quality, and dependability.

Sincerely,
Alex H.

Our company recently installed a Rangemaster AM1000 to provide community radio in our area. It has exceeded our expectations! Not only do we have superb range, but coupled with an Inovonics 222 AM processor, we actually sound better than the large FM stations in our area! The craftsmanship of this unit is excellent and its performance is every bit as good as our regular broadcast equipment. I highly recommend the AM1000 to any organization that wishes to provide quality “ON AIR” programming for a small community or other application. In our opinion, it’s the best on the market!
