To set full FCC allowed .1 Watt:
All current units ship with the Green light AM100T power set feature. Simply rotate the power to get a green light.

You can also set the power with a VOM Meter: Leave meter hooked up as described in tuning step. (Black lead in GND hole and Red lead in bottom hole) Note voltage reading (example 2 volts). Move black lead to bottom hole and move red lead to middle hole. Note voltage (example .5 volt). Using the chart in the manual, adjust the power level potentiometer on the transmitter until you are satisfied with the readings.  See this power chart to help make setting the power easy.

Plug your audio in and adjust Audio level for best sound. We recommend leaving the pot in the transmitter 3/4 up or more and adjusting the audio level from the ground if possible.

New alternative to the included AM1000pr audio interface, it is possible to use the MCM electronics 555-8485 as an unbalanced to balanced interface, let us know and we will pr

ovide the connectors/wiring you need to use this device at only a slight cost increase. We also stock this device.

Note that you only need an interface if you have a unbalanced audio driver, if you have a balanced driver it is possible to drive the transmitter directly.

For your audio source you can use a MP3 player, the new digital players work great. Some have removable media. Just be sure it has a "repeat" function. you will need a 3.5mm to 3.5mm male to male plug cable to plug the typical MP3 player into the studio interface. We can help make your MP3 player work in the system, for example if you need a power supply we can help find one, just give us a call. We recommend using an MP3 player that has a power supply, or an USB MP3 player with an internal rechargeable battery. Be sure your MP3 player power supply is designed to work with the player playing. We have USB power supplies in stock that will keep your USB rechargeable MP3 player powered 24/7, just let us know you need one when ordering.

The iPod shuffle is a great choice for your MP3 player audio source, just load your MP3 files, and set it to repeat. Be sure to buy the "on the go" power supply with it, you can get 110v AC or 12VDC adapters.

Or you could use a computer and one of many software packages available for sequencing audio files, some of which are shareware. You could simply use a CD player, with both music CDs and CDs that you record yourself. Be careful of royalties required for material you play on your station. Check out chat rooms and news groups for more information on this subject. Radio Shack makes a good mixer for small setups.
 

The Radio Shack mixers are #32-2057 $99 and 32-2058 $149. Radio Shack carries microphones and other equipment for your station. A great place to find equipment is MCM Electronics. An Innovonics 222 Audio Processor can increase your range and improve your sound.

Multiple Transmitters:

Need more range? It is possible to use more then one Rangemaster unit to cover more area. The easiest method is to spread them out over you area and synchronize the audio only. Because the units are crystal controlled and can be fine tuned to exact frequency this will work, they won't heterodyne unlike PLL controlled AM transmitters. However you will need a method to distribute the audio. Part 15 Microwave, cable, radio, Internet, phone line are a few possibilities. Helpful E-mail  from customer (see disclaimer above). It is also possible to place RANGEMASTER units around a large building/shopping mall and synchronize the audio and radio carriers together so they will synchronize with other using the onboard digital link.
