The test procedure used was TIA/EIA-603 S2.2.1. RF power is measured by connecting a 50 ohm, resistive wattmeter to the RF output connec- tor. With a nominal battery voltage of 13.8V, and the transmitter properly adjusted the RF output measures: INPUT POWER: (13.4V)(6.2A) = 83.00Watts OUTPUT POWER: 25.0Watts Efficiency: 30% 2.1046(a) RF power output.

The audio frequency response curve is shown in Exhibit 9. 2.1049 AUDIO LOW PASS FILTER Transmitters utilizing analog emissions and meets the requirements of paragraph 90.210(c) therefore no low-pass filter response in included. 2.1049 AUDIO INPUT VERSUS MODULATION The audio frequency input versus deviation was measured in accordance with TIA/EIA Specification 603 S2.2.6.2.1. with the follow- ing exceptions; starting with 1000Hz the input was increased well beyond the deviation changing. This measurement was repeated for the band limits and any frequency deemed appropriate.
