RF power is measured by connecting a 50 ohm, re- sistive wattmeter to the RF output connector. With a nominal battery voltage of 12.0 VDC, and the transmitter properly adjusted the RF output measures: POWER HIGH INPUT POWER: (12.0V)(0.97) = 11.6 Watts OUTPUT POWER: 5.8 Watts Efficiency: 45% POWER Medium Power INPUT POWER: (12.0V)(0.67) = 8.04 Watts OUTPUT POWER: 3.0 Watts Efficiency: 37.3% POWER LOW Power INPUT POWER: (12.0V)(0.40) = 4.80 Watts OUTPUT POWER: 0.5 Watts Efficiency: 10.4% METHOD OF MEASURING RF POWER OUTPUT /-----------\ /---------\ |Transmitter|---------------------|50 ohm | |under test | |Resistive| \-----------/ |Wattmeter| | \---------/ /-----------\ |Power | |Supply | \-----------/ 2.987(a) Voice Modulation characteristics: (a) AUDIO FREQUENCY RESPONSE See the EXHIBIT #10. 2.987(a) AUDIO LOW PASS FILTER The audio low pass filter is included and the plot is shown as EXHIBIT #12.

On any frequency removed from the assigned frequency by more than 100%, but not more than 250%: At least 35dB. On any frequency removed from the assigned frequency by more than 250%, of the authorized bandwidth: At least 43+log(P)dB. 90.210( d) 12.5KHz channel bandwidth equipment. For transmit- ters de signed to operate with a 12.5KHz channel bandwidth, any emission must be attenuated below the power (P) of the highest emission contained within the authorized bandwidth as follows; (1) On any frequency from the center of the authorized bandwidth f0 to 5.625kHz removed from fP0: Zero dB. (2) On any frequency removed from the center of the authorized band- width by a displacement frequency 7.27(fd-2.88kHz)dB. (3) On any freque…
