May 4, 2001 Federal Communications Commission 7435 Oakland Mills Road Columbia, MD 21046 FCC ID: K66VX-160V 731 Confirmation Number: EA100232 Correspondence Reference Number: 19084 RE: Vertex Standard Co., Ltd. 1/ The Confidentiality Fee was paid and the Confidentiality request box on FCC Form 731 was checked. However, none of the Exhibits were marked Confidential and no Confidentiality request letter was received. Please clarify your intentions in this matter. A confidentially letter was uploaded with the file name: Vertex_Confidentiality VX-160V.PDF 2/ It appears that this VHF unit does not fit into the operating requirements under Part 95. Please comment. Vertex would like to exclude filing under Part 95 for this application. 3/ Measurement data for AC line conducted emissions are not required for applications for certification of licensed transmitters. Further, this unit is battery powered. AC line conducted test was performed while the radio was operated and placed in the battery charger. The test data will be removed from the certification report. A revised test report was uploaded. 4/ Please note that the attenuation requirements for radiated spurious emissions as prescribed under Part 90 are 43 + 10Log(P) and 50 + 10Log(P). This is referenced to the desired signal (as measured) yielding dBc. The attenuation specification is not XX uV/M. The dBc is to be determined from the substitution method as described in the ANSI/TIA/EIA-603-1992 document. Please submit data / results obtained in this manner. Sec. 10 page 16 of the test report indicates that measurements (radiated spurious emissions) were performed according to procedures ANSI/TIA/EIA-603-1992, section 2.2.12. The reported test data are expressed as ERP in dBm. The margin is in dB. The test data are not expressed in XX uV/M as specified in this correspondence. However, test data have been reformatted in order to be presented in dBc.

VX-160V/180V Circuit Description 1 / 4 VX-160V/180V Circuit Description 1. Receive Signal Path Incoming RF from the antenna jack is delivered to the RF Unit and passes through a low-pass filter consisting of coils L1001, L1002 and L1031, capacitors C1004, C1005, C1008, C1010, C1014, C1016, and C1221, and antenna switching diode D1003 ( RLS135 TE-17 ). Signals within the frequency range of the transceiver enter a varactor-tuned band- pass filter consisting of coils L1010 and L1011, capacitors C1044, C1046, C1060, C1065 and C1068, and diodes D1011 ( HVC358B ), D1012 ( HVC358B ), D1013 ( HVC358B ) and D1014 ( HVC358B ), then amplified by Q1012 ( 2SC5006-T1 ) and enter a varactor- tuned band-pass filter consisting of coils L1017 and L1021, capacitors C1084, C1086, C1095 and C1097, and diodes D1018 ( HVC358B ) and D1019 ( HVC358B ), before first mixing by Q1026 ( SGM2016AM-T7 ). Buffered output from the VCO is amplified by Q1007 ( 2SC5005-T1 ) to provide a pure first local signal between 190.25 and 218.25 MHz for injection to the first mixer Q1026. The 44.25 MHz first mixer product then passes through monolithic crystal filter XF1002 ( HDF0028 , 5.5 kHz BW) to strip away all but the desired signal, which is then amplified by Q1033 ( 2SC4215Y TE85R ). The amplified first IF signal is applied to FM IF subsystem IC Q1037 ( TA31136FN- EL ), which contains the second mixer, second local oscillator, limiter amplifier, noise amplifier, and RSSI amplifier. A second local signal is produced from the PLL reference/second local oscillator of 14.60 MHz crystal X1001. The 14.60 MHz reference signal is tripled by Q1036 and capacitor C1209, Coil L1029, then resulting the 43.8 MHz second local signal delivered to mixer section of Q1037 which produce the 450 kHz second IF mixed with the first IF signal. The second IF then passes through the ceramic filter CF1001 ( ALFYM450G=K: only on “Wide” channels) or CF1002 ( ALFYM450F=K: only on “Narrow” channels) to strip away unwanted mixer products, and is then applied to the limiter amplifier in Q1037, which removes amplitude variations in the 450kHz IF, before detection of the speech by the ceramic discriminator CD1001 ( CDBC450CX24 ). Detected audio from Q1037 is applied to the audio high-pass filter, and then passed via the volume control to the audio amplifier Q1039 ( NJM2070M-TE2 ), which provides up to 0.5 Watts to the optional headphone jack or a 4-Ω loudspeaker. Squelch Control The squelch circuitry consists of a noise amplifier and band-pass filter within Q1037, and noise detector D1018 ( 1SS355 TE-17 ). When no carrier received, noise at the output of the detector stage in Q1037 is amplified and band-pass filtered by the noise amplifier section of Q1037 and the network between pins 7 and 8, and then rectified by D1028. The resulting DC squelch control voltage is passed to pin 37 of the microprocessor Q1014 ( M37516E6HP ). If no carrier is received, this signal causes pin 24 of Q1014 to go high and pin 20 to go high. Pin 24 signals Q1060 ( RT1P441U-T11-1 ) to disable the supply voltage to the audio amplifier Q1039, while pin 20 hold the green (Busy) half of VX-160V/180V Circuit Description 2 / 4 the LED off, when pin 24 is high and pin 20 is high. Thus, the microprocessor blocks output from the audio amplifier, and silences the receiver, while no signal is being received (and during transmission, as well). When a carrier appears at the discriminator, noise is removed from the output, causing pin 37 of Q1014 to go low and the microprocessor to activate the “Busy” LED via Q1014. The microprocessor then checks for CTCSS or CDCSS code squelch information, if enabled. If not transmitting and CTCSS or CDCSS is not activated, or if the received tone or code matches that programmed, allows audio to pass through the audio amplifier Q1039 ( NJM2070M TE2 ) to the loudspeaker by enabling the supply voltage to it via Q1037. Transmit Signal Path Speech input from the microphone is amplified by Q1017 ( NJM2902V TE1 ), after pre- emphasis by C1066 and R1054, the audio passes another section of Q1017. The processed audio may then be mixed with a CTCSS tone generated by Q1014 ( M37516E6HP ) for frequency modulation of the PLL carrier (up to ±5kHz from the unmodulated carrier) at the transmitting frequency. If a CDCSS code is enabled for transmission, the code is generated by microprocessor Q1014 ( M37516E6HP ) and delivered to D1004 ( HVC350B TRF ) for CDCSS modulating. The modulated signal from the VCO Q1002 ( 2SC5231C8-TL ) is buffered by Q1007 ( 2SC5005-T1 ). The low-level transmit signal is then passes through the T/R switching diode D1016 ( DAN235E-TL ) to the driver amplifier Q1015 ( 2SC5227-4-TB ) and Q1016 ( 2SK2596BXTL ), then amplified transmit signal is applied to the final amplifier Q1024 ( 2SK2974-T11 ) up to 5 watts output power. The transmit signal then passes through the antenna switch D1003 ( RLS135 TE-11 ) and is low-pass filtered to suppress harmonic spurious radiation before delivery to the antenna. 3-1 Automatic Transmit Power Control Current from the final amplifier is sampled by R1108, R1115 and R1125, and is rectified by Q1057 ( IMZ2A T108 ). The resulting DC is fed back through Q1032 ( FMW1 T98 ) to the drive amplifier Q1016 and final amplifier Q1024, for control of the power output. The microprocessor selects “High” or “Low” power levels. 3-2 Transmit Inhibit When the transmit PLL is unlocked, pin 7 of PLL chip Q1005 goes to a logic “Low”, and unlock detector Q1056 ( 2SA1586Y TE85R ) goes to a logic “High”. The resulting DC unlock control voltage is passed to pin 14 of the microprocessor Q1014. While the transmit PLL is unlocked, pin 22 of Q1014 remains high, which then turns off Q1029 ( CPH6102-TL ) and the Automatic Power Controller Q1032 ( FMW1 T98 ) to disable the supply voltage to the drive amplifier Q1015, Q1016 and final amplifier Q1024, thereby disabling the transmitter. 3-3 Spurious Suppression Generation of spurious products by the transmit…
