JOE DICHOSO FCC SUBJECT: FCCID: K66VR-500 REFERENCE: EA94428 On the test report that was submitted it had measurement data for three(3) frequencies, 30, 200, 1250MHz. I used 30MHz as the low frequency because radiated emissions limits in S15.109 cover this range. If you have any questions, please advise. Regards, Sid Sanders SAH/hs F:\CUS\Y\YAE\JD90722.EMA

Tenney Temperature Chamber TEST PROCEDURE GENERAL: This report shall NOT be reproduced except in full without the written approval of TIMCO ENGINEERING, INC. RADIATION INTERFERENCE: The test procedure used was ANSI STANDARD C63.4-1992 using a HEWLETT PACKARD spectrum analyzer with a prese- lector. The bandwidth of the spectrum analyzer was 100 kHz with an appropriate sweep speed. The analyzer was calibrated in dB above a microvolt at the output of the antenna. The resolution bandwidth was 100KHz and the video bandwidth was 300KHz. The ambient temperature of the UUT was 80oC with a humidity of 76%. FORMULA OF CONVERSION FACTORS: The Field Strength at 3m was estab- lished by adding the meter reading of the spectrum analyzer (which is set to read in units of dBuV) to the antenna correction factor sup- plied by the antenna manufacturer. The antenna correction factors are stated in terms of dB. The gain of the Preselector was accounted for in the Spectrum Analyzer Meter Reading. Example: Freq (MHz) METER READING + ACF = FS 33 20 dBuV + 10.36 dB = 30.36 dBuV/m @ 3m POWER LINE CONDUCTED INTERFERENCE: The procedure used was ANSI STAN- DARD C63.4-1992 using a 50uH LISN. Both lines were observed. The bandwidth of the spectrum analyzer was 10kHz with an appro- priate sweep speed. The ambient temperature of the UUT was 80oC with a humidity of 76%.

FCC ID K66VR-500 ANSI STANDARD C63.4-1992 10.1.7 MEASUREMENT PROCEDURES: The unit under test was placed on a table 80 cm high and with dimensions of 1m by 1.5m. The table used for radiated measurements is capable of continuous rotation. When an emission was found, the table was rotated to produce the maximum signal strength. At this point, the antenna was raised and lowered from 1m to 4m. The antenna was placed in both the horizontal and vertical planes. The situation was similar for the conducted measurement except that the table did not rotate. The EUT was setup as described in ANSIC63.4-1992 with the EUT 40 cm from the vertical ground wall. CIRCUIT_DESCRIPTION: In the receive is a dual conversion super hetrodyne . For a complete description of the circuitry please refer to the In- struction manual in exhibit 6. ANTENNA_AND_GROUND_CIRCUITRY This unit makes use of a external 5 inch antenna. The antenna is inductively coupled. This unit is powered from a 9.0V battery. No ground connection is provided. The unit relies on the ground tract of the printed circuit board. APPLICANT: YAESU MUSEN CO., LTD. FCC ID: K66VR-500 REPORT #: F:\CUS\Y\YAE\YAE267A9.RPT PAGE #: 2 APPLICANT: YAESU MUSEN CO., LTD.

The bandwidth of spectrum analyzer was 100 kHz with an appropriate sweep speed. When an emission was found, the table was rotated to produce the maximum signal strength. The antenna was placed in both the horizontal and vertical planes and the worse case emissions were reported. The receiver was put into the coherent mode by placing an antenna driven by a signal generator off site. The UUT was tested in 3 orthogonal planes. PERFORMED BY: S. S.
