	The FM-800 Series are professional grade mono/stereo FM transmitters operating in the commercial FM broadcast band (87.9 - 107.9MHz). Both models (FM-800 & FM-850) can be used as a stand alone FM transmitter or as an FM exciter for greater RF power (RF power amplifier required).The FM-800 series are one of the easiest available FM transmitters to program and operate, thanks to our latest development in digital programming circuitry. It is now possible to digitally program the frequency and the RF power with accessible direct dial switches on the front panel. Manual tuning or calibration becomes a thing of the past with these FM transmitters. The FM-800 series are currently the best affordable, stable and trouble free FM transmitters available on the market today; thanks to its new auto-compensation circuitry that will assure optimum RF linearity on a temperature range of -50°C to +50°C (-58°F to +122°F).The stereo generator of the FM-850 model features a full digital circuitry that allows a stereo separation greater than 45dB.Both models feature an incredible carrier frequency tolerance equal to, or greater than .0008% .
