VHF Reception

　　The incoming VI IF signal is passed through a low-pass

　　filter network，antenna sw itc hingdiodes D1074 （RLS135），

　　D1075 （RLS135） and D1015 （HVC131），and another low-

　　pass filter network to the RF amplifier Q1008（3SK296ZQ）。

　　The amplified RF signal is passed through a varactor con-

　　trolled bandpass filter consisting of L1017，L1018，and

　　D1010，D1011，and D1012 （all HVC365），then applied to

　　the first mixer Q1009 （3SK296ZQ） along w ith the first

　　local signal from the PLL circuit.

　　The first local signal is generated between 189.05 MHz

　　and 193.05 MI 1z，depending on the receiving frequency，

　　by the VHF \ C O，w hic h consistsof Q1076（2SC5374） and

　　varactor diodes D1049 （HVC365），D1050 （HVC131），

　　D1051（HVC365），and D1052 （HVC362）。

　　UHF Reception

　　The incoming UHF signal is passed through a low-pass

　　filter network，antenna switching diodes D1077

　?。∕A4P1250） and D1018（RLS135），D1019（RLS135），and

　　D1084 （HSC277），and another low-pass filter network to

　　the RF amplifier Q1001（3SK296ZQ）.The amplified RF

　　signal is passed through a varactor-controlled band-pass

　　filter consisting of L1006 and L1007，and D1002，D1003，

　　and D1004 （all HVC350B），then applied to the first mixer

　　Q1002 （3SK296ZQ） along w ith the first local signal from

　　the PLL circuit.

　　The first local signal is generated between 384.95 MI Iz

　　and 404.95 MHz，depending on the receiving frequency，

　　by the UHF V CO，w hich consists of Q1072 （2SC5006）

　　and varactor diodes D1046 （HVC375B） and D1047
