7 Circuit Description The VX-2R consists of a MAIN-UNIT, a FILTER-UNIT, a SW-UNIT, and a VCO-UNIT. The MAIN-UNIT contains the receiver front end, IF circuit, PLL circuit, the CPU, audio ICs, and the power circuitry for the LCD. The FIL- TER-UNIT contains the CTCSS/DCS Encoder/Decoder cir- cuit.
8 Circuit Description to varactors D1016 and D1017 (both HVC355B ) in the variable frequency band-pass filters. By changing the elec- trostatic capacitance of the varactors, optimum filter char- acteristics are provided for each specific operating fre- quency.
9 ( 4 ) 435-MHz-Band Transmission Modulating audio passes through deviation setting D/A converter Q1010 ( M62364FP ) then delivered to the UHF modulator of the VCO-UNIT mounted on the MAIN- UNIT.
10 Circuit Description Note.
11 Alignment Introduction The VX-2R is carefully aligned at the factory for the spec- ified performance across the amateur band. Realignment should therefore not be necessary except in the event of a component failure.
12 Alignment Internal System Alignment Routine This process uses a programmed routine in the transceiv- er which simplifies many previously complex discrete component settings and adjustments with digitally-con- trolled settings via front panel keys and LCD indications.
13 TX Low Power (Low Band Edge) Adjustment (LP) r Press the [ V/M ] ke y. r Transmit, and adjust the output power level for 0.1 W (±0.05 W) by rotating the DIAL knob, then press the [ V/M ] ke y. r Rotate the DIAL knob to select the next setting. TX Deviation (Low Band Edge) Adjustment (dEV) r Press the [ V/M ] ke y.
14 CTCSS Tone (254.1 Hz) Deviation (High Band Edge) Adjustment (254) r Press the [ V/M ] ke y. r Transmit, and adjust the deviation for ± 0.6 kHz (±0 .05 kHz ) by rotating the DIAL knob, then press the [ V/M ] ke y. r Rotate the DIAL knob to select the next setting.
15 W ide FM Low-Scale S-1 Adjustment (S1) r Press the [ V/M ] ke y. r Adjust the generator level to 0 dBµ (1 kHz tone @ ±20 kHz deviation), then press the [ F/W ] ke y. r Press the [ F/W ] key again, then press the [ V/M ] ke y. r Rotate the DIAL knob to select the next setting.
16 Alignment TX Deviation (High Band Edge) Adjustment (dEV) r Press the [ V/M ] ke y. r Inject a 1 kHz audio tone at a level of 50 mV (rms) to the MIC jack, then press the [ F/W ] ke y. r Transmit, and adjust the deviation for 4.2 kHz (±0.2 kHz) by rotating the DIAL knob, then press the [ V/M ] ke y.
