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% .
APPLICATIONS: Decade transmitters are intended for use
in low power broadcast stations, community and campus radio
but can also be used (where allowed) for multi-lingual
conferences, play by play broadcast inside arenas and
stadiums(the FM-800 series are able to cover a 42,000 seats
stadium when used with good quality FM walkmans at the
receiving end). Applications are endless...

The best receivers have a separation of 40dB, so the effective separation
is more a matter of the quality of the receiver.
