Q&A
Overview: Here's your ultimate opportunity to lead with your own high quality part 15 radio station. We offer the only crystal controlled part 15 certified for FCC part 15.219 operation. Not only that, when set up correctly the audio quality is substantial, loud and powerful. Recient upgrades and testing based on our suggestions prove a PROPER INSTALL will reach out 2-miles solid radius and a signal detectable beyond that. One could add additional transmitters on the same site to increase coverage. The kits just dont get out - plain and simple. Our Rangemaster is the only way to go for several reasons - give us a call. Have in your control the tools needed to get the truth out to your local area 24/7 while you work on other things. Once you get your station up and announce it in the area, you may find others willing to donate funds or time to expand or help get the word out just as we experienced shortly after going live. We are not here to make a living doing this. We are here because this is the right thing to do and the outcome will be significant to waking up your neighbors while exposing them to the cons and crooks who direct our lives without most of us realizing it. It's time to up the annie with various older technologies - AM Broadcast legally! We are not marking up the Rangemaster AM 1000 transmitter acting as a middleman. This is a special project for the purpose of waking people up. Here you get the best price possible and the help you need. We work with the creator of these units and have the experience to show you the way. If talk radio is squelched - you will still have your unlicensed Part 15 Station - because you are non-commercial you will remain on the air with the truth! Get ready to direct your neighbors to when and were on the dial to tune on a moments notice! |


Please see our new Q&A section with testimonials - some more instructional help videos will be posted as we have time including a drive showing actual coverage
Retransmit your favorite streams in the neighborhood. No internet? Retransmit K-Band satellite transmissions. Start your own studio with a simple mixer board. We can also suggest a solid audio/mixer board for your PC which has dual inputs and outputs. No PC at the Transmitter location? Use our BARIX Exstreamer to "pull" our feed or any other Shoutcast 24/7.
Internet down? No satellite? How about the phone lines - feed audio to your transmitter directly from the phone using a matching transformer. Example this number 1-610-404-5954 has Alex Jones round the clock.We are getting a LOT of calls from people without internet and this is the answer to retransmit your satellite or desktop studio reliably. Need more coverage? Just daisy chain several units for unbelievable signal strength. The best thing to do is add your location to our location help forum. Someone in the area is bound to want to chip in together to get the job done but please spread the news about our product as time is running out!
What we offer:
By choosing the best frequency this transmitter will operate in neighbors homes at full fidelity. My local system now covers most driven traffic areas quite well and we are now enhancing the areas in between. You can put two or more in one spot for increased power but enhancing the audio is key.
Many car radios use amplified antennas (on AM) for more coverage, especially in GM, BMW and Ford vehicles.

What does the Transmitter Purchase Contain?
What are the minimum items you will need?

Here is a map of Tulsa. The black is a typical non-certified Part 15 kit showing results for daytime use. The green is the result for a average to poor install of the Rangemaster and the blue is what can be achieved with careful planning, proper channel selection and attention to detail.
What are the optional items to consider?
Quick set-up of Barix IP-MP3 decoder which feeds our 24 hour audio programs to the transmitter on the roof of this Omaha home. Normally you could tie the audio from the Barix or your MP3 player right to the AM-1000PR (black item behind the Barix). Above we are using a Audimax 4440 as a automatic limit & gain control so up here in S. Dakota I can very the signal and it always sounds the same to someone in their car, etc.. These are hard to find so the next best choice is a Limiter/Compressor which can be bought for $50 on ebay.

This one has all the best equipment (Well I like the Audimax over the MDX1600). The tan item is the Inovonics 222 which takes advantage of the audio peaks to expand modulation which results in what could be an extra 1/4 mile radius of coverage.

You should with very little effort start attracting attention of those like minded around you. This may and should result in help and donations for your project. I would first suggest getting the word out in local truth or liberty movement groups.
I suggest putting together a greeting card or welcome letter to pass around with a business card and one of many DVD's.
One could put an hour of Alex Jones or Alan Watt on a CD as a sample. That resulted for me in a sizable donation! I then ordered 50 copies of Richard Gage's new Research Edition DVD to help them which gave me authorization to make extra copies and hand these out locally. I literally pin up CD's with the station call letters on the community board at the grocery store down the street.
We can instantly have business cards and signs printed for you at a low fee as the set-up work is done. Please check out our form letter for your neighbors here. Also below is a sample poster.
More Specifications and Help
You can drive the RangeMaster AM1000 FCC certified transmitter with audio from almost any audio source. Customers use CD players, computers, digital players, and many other sources. If you specify your audio source when ordering we will try to provide any needed interface though the included AM1000PR audio adapter will provide the needed interface for most situations. Please let me know.A audio adapter (AM1000PR) is included with the transmitter that will adapt the 600 ohm balanced audio the transmitter uses to an unbalanced 3.5mm jack.
Download this diagram PDF file for general audio connection information.
Download this diagram for our Barix/IP-MP3 feed connection.A standard 16-24-volt wall transformer is included for a power source.
The Rangemaster can be modulated 130% positive and 90% negative peak for that "BIG" station sound! We recommend the Inovonics 222 or CRL PMC-300A as an excellent companion to the AM1000.
A special feature of the AM1000 Rangemaster is that the units can be synchronized together for greater range. You can mount multiple units on your building (for example a shopping mall) and link them together so they will match signal phase and work together. The RF signals will actually add in the air. Each additional transmitter will add 20% to the signal if tuned properly. I personally can attest to the success of this.

Frequency Notes:
Please choose 2 transmit frequencies 1590Khz 1600Khz 1610Khz 1620Khz 1630Khz 1640Khz 1650Khz 1660Khz 1670Khz 1680Khz 1690Khz 1700Khz 1710Khz and include choice in the comments section when you pay. 1610Khz or 1620Khz or 1710Khz are recommended, as these frequencies are usually the quietest. (Check your frequency choice in your area by listening in during different times of the day to that frequency before your order.) Using the higher frequencies (above 1400Khz) is recommended as there is less background noise and the transmitter is more efficient at the higher frequencies.Before you order please choose your frequencies by first eliminating the ones who have the right to broadcast in your area by scanning the upper frequencies in the day time. You can find most of them by searching any city of any size at www.city-data.com.
Then over the period of 4-nights check at different locations in your general area for the cleanest frequency. In the early Spring this can change greatly from 4:30 PM to 7PM and improve later than 8. Stations in the 1610 to 1700 range generally switch from 10KW to 1KW at or around 7PM. So summertime your station will have lower noise to deal with on these better upper frequencies.

Multiple Transmitters (now expanded to a page of its own)
Multiple transmitters can cover the area you need if one transmitter won't do the job. The most common method people are using to cover a larger area with multiple transmitters is place RangeMaster transmitters around town and link them by Internet using a IP/MP3 decoder by BARIX, see this link.
When using this method there are some important things to know. First you need to keep your audio in sync, even a few tenths of a second delay of audio between the transmitter s will cause a noticeable echo as a person drives between transmitter zones. Second, the RF carrier is not in phase sync using this method, the transmitters will not heterodyne (you must use the crystal controlled model) but the PHASES of the carriers will not be synced. Normally you will have a short zone of "flutter" as you drive between zones, not too noticeable, like driving under a power line. However if you don't do a good job of planning transmitter locations and get the transmitters to close together then the flutter will become worse. Do not try to use other (PLL) type transmitters with this method, you can get into all kinds of heterodyne problems.More on the phase linking with our hardware
An alternative is to have one system pick up the audio, then connect near and/or far your other transmitters via microwave (also part 15). This system also works with our transmitters for seamless coverage. This particular unit we are testing is analog so there are no delay latency problems.
Only Microwave, GPS and direct wiring will allow for perfect phase coordination. The quality of the Rangemaster I must say works well for those who can only depend on the crystal control to zero-beat other non synchronized transmitters. At least with the Barix you can easily adjust the delay.Additional ways to link and/or synchronize your studio or main transmitter to 2nd and third transmitters:
Dedicated Phone Line
ISDN and Comrex over telco
SCA Transmitted signal (FM sideband) service from local FM station
Local wireless internet service to provide IP/MP3 at distant location. This is also a good back-up system ie - no wires to cut from DSL service.. Can operate 100% on battery and solar. (one must purchase their proprietary wireless modem which uses privately licensed frequencies to guarantee no interference.)Additional uses of our BARIX unit with or without a transmitter
- Public address systems - just pull our signal or your favorite stream from the internet or ethernet system without any transmitter in range. Great for anything from Bowling Alleys, Barber shops, lobbys, old folks homes, etc..
- Add the shows to a relative's home or work place. Great for elderly who don't own a computer but DSL or a cable modem could easily be installed to feed the unit.
(just connect the BARIX Exstreamer to a audio in on home stereo or radio.- Use on your mobil unit with wireless internet. I have a part 15 FM transmitter set-up on my car which I can transmit either live shows when parked for a event's public address or repeat a recorded message to advertise the station while moving.
- Portable AM set-up at remote site.
- BARIX Instreamer 100 allows you to send your studio's audio to remote locations.
- Listen to my feed flowing through our Barix Instreamer live right now.

Testimonials:
Hi Ches:
I went for a drive this evening scouting for your 72nd and Blondo signal. I am amazed at the quality and strength of the Rangemaster signal. I didn't drive it much, but I was able to hear up and down 72nd between Decatur and Maple. Perhaps other places, but at first, I wasn't sure what I was listening for.
My SSTRAN sounds great, but I don't think the range is as good as the Rangemaster. My nighttime coverage shrinks down really bad.
I don't think 1640 would be a good frequency for areas south of Dodge or Center. The sports station at 1620 just splatters all over the upper AM dial. I chose 1690 for that reason. http://robinvalley.org/faq.shtml The 1620 station is around 60th and Harrison.
If I can, I'll get out this weekend and do some range testing on your 72nd and Blondo transmitter. I'm curious just how good the Rangemaster is.
When I start the station back up, I may very well carry AJ and other freedom related shows, but at this time, I want to keep the Robin Valley identity. However, there may be blocks of time that I don't want to program. I might ask to carry your feed during these times.Scott (Omaha part 15 user)
This was without the help of a Inovonics 222 or other limiter/modulator. The Omaha transmitter was running at 100% with the Audimax 4440 gain control unit which keeps the audio compressed and consistent.
Testimonial #2 - A friend ran into someone here in town who listens to the live internet feeds daily - Although they are just outside of the range of your transmitter most the time, it was your signal which led them to find infowars.com for the first time.
Your station is not only a station, it's a beacon of hope which has recruited another soldier into the battle for our freedom. Sleep well my friend but don't sleep too long. We need more signals out there.

If you are totally new to these concepts and have very little electrical or mechanical aptitude please contact a local Ham Radio club for assistance. They have the knowledge to properly and safely install RF or Radio systems in compliance. They can also help you adjust the units via field strength and are generally experts in grounding systems.
Just search your city - armature radio club or ham radio club with your city in the search.
My short story...
Our profits are minimal - really; we want to get these quality units and systems out there before it's too late. I never intended to sale these systems until it was suggested by others in the battle do so. After installing five and working with radios all my life- the reaction came naturally. So we now want to help get these units installed across the country. As other hardware is tested and deemed useful I negotiate prices which cannot be beat elsewhere.
It is not possible for the designer & manufacturer of the Rangemaster provide assistance for what this project requires. These units require a lot of RF knowledge so I offered to take on this project in the name of getting the truth out there now and to HELP YOU TO DO THE SAME.
I want to help you get your station on air!I have built the kist and talked to others who have built other popular kits on forums, etc. The $100 kit will get you on the air but after hours and hours of anguish, research, purchase of test equipment, etc. Not to mention the endless antenna design problems. The Rangemaster has it all available for you and the antenna coil is built into the weatherproof transmitter.
No kit or the other certified unit will get the range or the improved modulation.You will be disappointed if you get the kit on the air then hear one of these. Music fidelity is even better.We have the transmitter, the audio source, the linking tools, ideas help and connections to the future of new networks you may want to choose from.
One last comment - A strong website for your station could rank above the commercial stations - this will certainly get attention too, possibly reaching advertisers to help pay for the project.
If this is out of your reach I would like to offer other options which will help our quest for freedom.
- Put your location on our Regional Support forum page incase someone else finds us from your area, we can organize you together to get a station up of funding assistance.
- Subscribe to American Free Press through us. We are authorized to set up subscriptions and the profits go back into this project. You too can become a Distributor.
- Donate! The funds here go into the operating costs of the station and more advertising to get the word out. We can make $5 to $25 go a LONG way.
- Helps pay for our time on the phone or on the road helping others get set up. I don't ask for money to do that and it cuts into time needed for our main sales business but that's alright. I'd rather do this.
- Larger donations will get you one of the feature books as a thank you, which we also buy from other patriot businesses helping them as well.
- Extra funds will go into expanding our local Sioux-Falls/Omaha network which could cover up to 583K population and work on a Certified Part 15 Television transmitter.
Do you want to hear the signal? You really get your moneys worth with the AM Rangemster.. With FM you dont.
A new Experimental antenna for about $20
I used a 1/2 inch 10" copper pipe, pipe end, adapter and threaded unit to match to a makeshift PVC mast and it had noticeable improvements over the $30 Radio Shack 102" whip. This antenna is within the 10 foot regulation.
Parts for antenna - this cost me $14.83 at Manards - improves coverage as it is the full 10 foot length (maximum allowed by FCC for Part 15) The cap for the 10 foot pipe is not shown.
