The block diagram is included as PAGE 6. (8) Instruction book. The instruction manual is in cluded as 10A-10B. (9) Tune-up procedure. The tune-up procedure is given in the user's manual. (10) Description of all circuitry and devices provided for determining and stabilizing frequency is included in the circuit description in 11A-11C. 2.983 (11) Description of any circuits or devices employed for suppression of spurious radiation, for limit- ing modulation, and for limiting power. In addition to the interstage filtering the multi- section low pass filter is described in paragraph 6.3.5 of the instruction manuel. Limiting Modulaton: The transmitter audio limiting circuitry is con- tained in the loop filter U501, U502, & U503. Limiting Power: The power is preset at the factory for either high or low. There is no provision for limiting power. (12) Digital modulation. This unit does NOT use digi- tal modulation. 2.983(e) The data required by 2.985 through 2.997 is submitted below. 2.985(a) RF_power_output. 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 7.2V, and the transmitter properly adjusted the RF output measures: INPUT POWER: (7.2V)(1.5A) = 10.80Watts OUTPUT POWER: 5.4 Watts Efficiency: 47% INPUT POWER(LO): (7.2V)(0.9) = 6.48 Watts OUTPUT POWER(LO): 1.3 Watts Effeciency: 20% APPLICANT: YAESU MUSEN CO., LTD.
