13 Circuit Description 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 L1003, capacitors C1001, C1002, C1021, C1022, C1023, C1024, C1025, C1026, and C1027, and antenna switching diode D1004 ( RLS135 ).
14 Circuit Description ode D1048 ( HSC277TRF ) to the buffer amplifier Q1024 ( 2SC5005 ), pre driver amplifier Q1020 ( 2SC3357 ), driver amplifier Q1014 ( RD01MUS1 ), and then the am- plified transmit signal is applied to the final amplifier Q1008 ( RD07MVS1 ), which delivers up to 5 watts of output power .
15 Alignment Introduction The VX-410/-420 series has been aligned at the fac- tory for the specified performance across the entire fre- quency range specified.
16 Alignment The transceiver must be programmed for use in the intended system before alignment is attempted. The RF parameters are loaded from the file during the alignment process.
17 TP1045 L1038 PLL VCV (Varactor Control Voltage) Ì Connect the DC voltmeter between TP1045 on the Main Unit and ground. Ì Set the transceiver to CH 3 (high band edge), and ad- just L1036 on the Main Unit for 4.0 V ± 0.1 V on the DC voltmeter . Ì Set the transceiver to CH 1 (low band edge), and con- firm the low-end V CV is more than 0.
18 Alignment CTCSS Deviation Ì Set the transceiver to CH 2 (band center). Ì T o adjustment, click the left mouse button on the “ CTCSS Modulation ” box, then press the [ ENTER ] key to open the pop-up window . Ì Use the [ ] or [ ] arrow keys so that the deviation meter reading is ±0.
