The UM200C transmitter is a high performance synthesized UHF design that offers the frequency agility needed to alleviate interference and frequency coordination problems in travelling applications. Interference caused by television broadcasts and other radio equipment can easily be avoided with 256 available frequencies selected in 100kHz steps with two rotary switches on the side panel.
FEATURES:
No pre-emphasis/de-emphasis
Pilot tone squelch
Wide-band deviation
Long battery life
Frequency agility
Frequency selection: 256 frequencies in 100kHz steps
RF Power output: 100 mW (nominal)
Pilot tone: 32.764 kHz (+/- 2Hz); 5kHz deviation
Frequency stability: +/- 0.002%
Deviation: +/- 75 kHz (max)
Spurious radiation: 90 dB below carrier
Equivalent input noise: +/-126 dBV
Input level: Nominal 2 mV to 300 mV, before limiting.
Greater than 50V maximum, with limiting.
Input impedance: Taps provided for 500, 1k, 10k Ohm
Input compressor: Soft compressor, >30 dB range
Gain control range: 43 dB; semi-log rotary control
Modulation indicators: Dual LEDs indicate modulation level 12dB below limiting and at the onset of limiting.
Low frequency roll-off adjustment: +/-18dB/octave; 35Hz to 150Hz
Controls: 2 position “OFF-ON” slide switch for noiseless turn on/turn off operation.
Front panel knob adjusts audio gain. Recessed control on side panel adjusts low frequency rolloff. Rotary switches on side panel adjust transmitter frequency.
Audio Input Jack: Switchcraft 5 pin locking (TA5F)
Antenna: Detachable, flexible wire supplied. 50 Ohm port allows connection to test equipment.
Battery: Precision compartment auto-adjusts to accept any known alkaline 9 Volt battery.
Battery Life: 4.5 hours (alkaline); 14 hours (lithium)
