Transmitter Characteristics

TYPICAL DUTY CYCLE

" ypical duty cycle" is defined as nine minutes of receiving or

monitoring for each one minute of transmission time; expressed as 9:1

duty cycle.

MANPACK BATTERY

With a 9:1 duty cycle, at 70 degrees F., a new manpack main power

battery (BA-5590) has a service life of approximately 10-30 hours

depending upon RT version and level of usage. (See Chapter 8 for

additional data regarding service life expectancy of manpack

batteries.)

POWER DRAIN

Manpack transmission maximum power draw is 3.25 amperes;

vehicular radio is 6.25 amperes.

CARRIER DEVIATION

Carrier deviation (voice) is 6.5 Kilohertz (KHz) with audio input of 1.4 to

140 millivolts.
