FCC ID: K66RP80V REPORT #: F:\CUS\Y\YAE\YAE80A9.RPT PAGE: TABLE OF CONTENTS GENERAL_INFORMATION_REQUIRED FOR_TYPE_ACCEPTANCE 2.983 (a,b,c) YAESU MUSEN CO., LTD. will sell the MODEL NO. K66RP80V VHF transmitter in quantity, for use under FCC RULES PART 22 & 90. 2.983 (d) TECHNICAL_DESCRIPTION (1) Type of Emission: 10K6F3E For 25KHz 10K6F3E For 12.5KHz For 25KHz Bn = 2M + 2DK M = 3000 D = 2.3KHz (Peak Deviation) K = 1 Bn = 2(3.0K) + 2(2.3K)(1) = 6.0K + 4.6K = 10.6K ALLOWED AUTHORIZED BANDWIDTH = 20.00KHz. For 12.5KHz Bn = 2M + 2DK M = 3000 D = 2.3KHz (Peak Deviation) K = 1 Bn = 2(3.0K) + 2(2.3K)(1) = 6.0K + 4.6K = 10.6K ALLOWED AUTHORIZED BANDWIDTH = 11.25KHz. 90.209(b)(5) (2) Frequency Range: 146-174 MHz (3) Power Range and Controls:There are NO user Power controls. (4) Maximum Output Power Rating: 50 Watts , into a 50 ohm resistive load. (5) DC Voltages and Current into Final Amplifier: POWER INPUT FINAL AMPLIFIER ONLY Vce = 13.6 Volts Ice = 13.2 A. Pin = 179 Watts APPLICANT: YAESU MUSEN CO., LTD.

(10) Description of all circuitry and devices provided for determining and stabilizing frequency is included in the circuit description in the instruction manual. 2.983 (11) Description of any circuits or devices employed for suppression of spurious radiation, for limiting modulation, and for limiting power. In addition to the interstage filtering the multi- section low pass filter made up of LT01, CT01, CT04, LT02, & CT06. Limiting Modulaton: The transmitter audio limiting circuitry is contained in the loop filter IC01. Limiting Power: There is no provision for limiting power. (12) Digital modulation. This unit does NOT use digital modulation. 2.983(e) The data required by 2.985 through 2.997 is submitted below. APPLICANT: YAESU MUSEN CO., LTD. FCC ID: K66RP80V REPORT #: F:\CUS\Y\YAE\YAE80A9.RPT PAGE #: 2 2.985(a) RF_power_output. RF power is measured by connecting a 50 ohm, re- sistive wattmeter to the RF output connector. With a nominal battery voltage of 13.6VDC, and the transmitter properly adjusted the RF output measures: POWER INPUT POWER: (13.6V)(13.2A) = 179 Watts OUTPUT POWER: 50.0 Watts Efficiency: 28% 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 #9. 2.987(a) AUDIO_LOW_PASS_FILTER The audio low pass filter is included and the plot is shown as EXHIBIT #11. Rules 90.210(b,d, & e) for mobile stations with a low pass filter. 2.987(b) Audio_input_versus_modulation A plot of the audio input versus deviation is shown in in EXHIBIT #10.

FCC ID: K66RP80V REPORT #: F:\CUS\Y\YAE\YAE80A9.RPT PAGE #: 3 2.989(c) Occupied_bandwidth: 90.210(b,) Data in the plots shows that on any frequency removed from the assigned frequency by more than 50%, but not more than 100%: At least 25dB. 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.
