$2.983 (d)(6) 2.983(d) (7) Complete Circuit Diagrams: The circuit diagram is included as PAGES 7-9. The block diagram is included as PAGE 6. (8) Instruction book. The instruction manual is in cluded as 11A-11D. (9) Tune-up procedure. The tune-up procedure is given in exhibit 13A-13F. (10) Description of all circuitry and devices provided for determining and stabilizing frequency is included in the circuit description in 12A-12D. 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 AVERAGE CONDUCTED OUTPUT POWER: 5.4 Watts Efficiency: 47% INPUT POWER(LO): (7.2V)(0.9) = 6.48 Watts AVERAGE CONDUCTED OUTPUT POWER(LO): 1.3 Watts Effeciency: 20% APPLICANT: YAESU MUSEN CO., LTD.

$2.993(a)(b) Field_strength_of_spurious_emissions: The tabulated Data shows the results of the radiat- ed field strength emissions test. The spectrum was scanned from 30 to 4.7 GHz. This test was conducted per ANSI C63.4-1992 with the exception of briefly connecting the transmitter to a half wave dipole for the purpose of establishing a reference. NAME OF TEST: RADIATED SPURIOUS EMISSIONS REQUIREMENTS: Emissions must be 43 +10log(Po) dB below the mean power output of the transmitter. HIGH POWER 50 + 10log(5.4) = 57.30 dBc or 70dBc, whichever is the lessor. 50 + 10LOG(1.0) = 50dBc NOTE: FOR THE MARGIN CALCULATION BELOW 70dB WAS USED.

$2.993(a)(b) CONTINUED: Field_strength_of_spurious_emissions: METHOD OF MEASUREMENT: The procedure used was TIA/EIA-603 STANDARD. The spectrum was scanned from 30MHz to at least the tenth harmonic of the fundamental using a HP model 8566B spectrum analyzer, an Eaton model 94455-1 Biconical Antenna, a ElectroMetrics antennas models TDA, TDS-25-1, TDS-25-2, RGA-180. Measurements were made at the open field test site of TIMCO ENGINEERING INC. located at 6051 N.W. 19th LANE, GAINESVILLE, FL 32605.
