The features of the AM1000 are too numerous to fully cover:

The Legality! Rest assured that you can operate under the law, and if there is a issue we will be there to help.
RangeMaster digital link! Only RangeMaster has this RS485 carrier interface. This link allows great flexibility in designing your multiple transmitter system. With this link it is possible to synchronize RF carriers between transmitters.
GPS controlled sync capability for multiple transmitters! (RF carrier, not the audio)
Quality Construction! Assembled in USA!
Onboard included "Green light" power set system makes setting the power easy! (Just let us know if you would rather have a voltmeter)
The outdoor box is 1/4 inch fiberglass (better then metal) wall, made in Germany, designed for many years of service.
Repair record! The only repairs we get are units dropped from towers and lighting related (be careful in routing cables)
Power! Power is adjusted and controlled by you! Some (store bubble packed) transmitters and others do not have adjustable power and typically are not operating at the full allowed power.
Stability! Rock solid stability, like the big stations! This is critical for several reasons. click
Great installation video! 40 minute install video goes through the areas of installation in detail.
AM1000PR studio module! Easy interface provides a transmitter wire to audio 1/8"
plug connection.
Great Range! The RangeMaster range is legendary!
Great sound! Near FM sound quality! Virtually flat response from 20hz thru 20khz!
Only Part 15 with Asymmetrical capability! Drive the AM1000 to 125% mod with an AM audio processor like the Innovonics 222 or Volumnmax (These audio processors are designed to be used with an AM transmitter). Or improve you sound with a standard processor (like a Behringer Autocom Pro MDX1400). Some transmitters have a single chip included audio processor which is typically not very helpful.
Resale! You are not buying junk! resale value is high on our product.
Long life design! Our transmitters are designed to last many years.
Lighting protection! Antenna has gas tube protection, balanced audio in is transformer isolated (helps prevent ground loops and adds protection and isolation) Power also has protection.
Temperature range! We have units operating in the desert and in the artic!
Low power consumption. Great for solar applications.
Of course, no FCC license required.
Not a kit, fully assembled. (It is illegal to sell transmitters without being certified).
We recommend using high quality shielded wire which we can supply.
