Frequency Agile UHF Belt-Pack Transmitter
Rio Rancho, NM – USA
The FCC requires that the following statement be included in this manual:
This device complies with FCC radiation exposure limits as set forth for an uncontrolled environment. This device
should be installed and operated so that its antenna(s) are not co-located or operating in conjunction with any other
antenna or transmitter.
Operating frequencies:
537.600 to 607.900 MHz
614.100 to 767.900 MHz
768.000 to 805.600 MHz (export only)
Frequency selection:
256 frequencies in 100 kHz steps
RF Power output:
Greater than 50 mW
Pilot tone:
25 to 32 kHz frequency; 5 kHz deviation (400 Series only)
Frequency stability:
± 0.002%
Deviation:
± 75 kHz (max)
Spurious radiation:
60 dB below carrier
Equivalent input noise:
–120 dBV, A-weighted
Input level:
Nominal 2 mV to 300 mV, before limiting.
Greater than 1V maximum, with limiting.
Input impedance:
2k Ohm
Input compressor:
Dual envelope, >30 dB range
(Note: The dual envelope “soft” limiter provides exceptionally good handling of
transients using variable attack and release time constraints.)
Gain control range:
43 dB; semi-log rotary control
Modulation indicators:
Dual bicolor LEDs indicate modulation of -20, -10, 0, +10 dB
referenced to full modulation.
Low frequency roll-off:
–12 dB/octave; 70Hz
Audio frequency response (overall system):
90 Hz to 20 kHz (+/- 1 dB) with the 70Hz low frequency roll-off filter.
(Note: The transmitter is deliberately rolled off at 70Hz to reduce the undesired
effects of the lower frequencies.)
Controls:
2 position “OFF-ON” slide switch for noiseless turn on/turn off operation.
Front panel knob adjusts audio gain.
Rotary switches on side panel adjust transmitter frequency.
Audio Input Jack:
Switchcraft 5 pin locking (TA5F)
Antenna:
Galvanized steel, flexible wire.
Battery:
Precision compartment auto-adjusts to accept any known alkaline 9 volt battery.
(We’ve tried 243 different ones!)
Battery Life:
6 hours (alkaline); 13 hours continuous (lithium)
Weight:
6.3 ozs. including battery
Dimensions:
3.1 x 2.4 x .75 inches
Emission Designator:
180KF3E
