Various accessories are packed with the transceiver: Make sure vou have not overlooked anything 1.
Iog p Tel BATTERY INSTALLATION When using Nickel-Cadmium power pack IC-BP3: The 1C:BP3 s & rechargeable: Nickel:Cadmium: power pack; and it can be slipped: onto or off the servery gassing. It has connector for a charger charge-currant control circuit; reverse polarity protection circuit ‘and: charge indicator: LED in it own pack.: You can use the supplied BC:25L) wall charger of similar simple wall charger, 'or a car battery by using optional cable 1C-CP1 for recharging.
e Connect the output plug of the wall charger (BC:28U), or other power source, to the charger socket of the power pack. (When charging Nickel-Cadmium batteries in the 1C-BPA power pack, you should use the BC-30 charger only.y The charge indicator LED of the power pack is Iit; which shows that the charger is working: 15883 ‘ Cigarette \C:BP3 Lighter plug: OUTLET it takes about 15 hours to charge the batteries completely.
Whitening the alkaline power pack |C-BP4: Place tha power switch in'the OFF position. ‘Remove the power pack from the bottom of the set by pushing the pack in the indicated direction. Separate the pack into two parts {cases) as follows: Each case holds three ‘AA type batteries.
shortened more by transmitting than by receiving. since several times more current is drawn dding transmission: To proton battery life, therefor, practice the following: * U Taro minimize the transmit period: * Reduce volume during reception, ¥ Be sure to cut off power source whee set is not used. More working hours are-available i f high-performance batteries are employed. FOR. OUTDOOR: USE 1.0 Attach the supplied power pack. {Referent BATTERY INSTALLATION) 2.
EXTERNAL ANTENNA 1. Select a high performance antenna {a multi-element beam 'of gain antenna} and set it up in the highest possible position. 2.7 Use 2 50 ohm antenna and coaxial cable, 3. Onus, the power loss in the antenna cable is large, souse a cable with the lowest possible Toss and mask 1t assort as possible 4. Use a BNG plug for:connection to the unit.
ANTENNA CONNECTOR Connect the supplied flexible antenna. An external antenna can be Used; using s BNC connector: TRANSMIT/BATTERY INDICATOR Ruminates jn the transmit mode: | Else indicates the battery condition; during transmission. Thai voltage of Nickel:Cadmium batteries drops: rapidly:just before they are exhausted, so when this indicator goes out, be sure to immediately stop using it, and charge the batteries again. SQUELCH CONTROL Sets the squelch threshold Revel.
& RE POWER SWITCH Selects' the RF output power HIGH 1.5 Watts {at 8.4V) or \LOW 0.15 Watts (at 84V In the LOW position, the current drain is decreased, to prolong the battery ifs DUPLEX/SIMPLEX SWITCH Selects the operation mode: DUPLEX for repeater operation, or: SIMPLEX for the same receive/ transit frequency operation.
—18= SECTION VI OPERATION RECEIVING Make sure the 13 POWER SWITCH is in the OFF position, and before turning ON the power switch; confirm as follows: 155 Mali suite the parer pack is'properly charged and attached 1o the set 2. ‘Make sure the supplied flexible antenna is properly set.
TRANSMITTING Set the controls and switches as follows: % RF Power Switch HIGH 4 DUPLEX/SIMPLEX SWITCH (see below) {5 DUPLEX MODE:SWITCH (see below) For simplex -operation, set {0 DUPLEX/SIMPLEX . SWITCH at the SIMPLEX position, making A3 DUPLEX ‘MODE SWITCH nonfunctional.

SECTION VL CIRCUIT DESCRIPTION RECEIVER: CIRCUITS ANTENNA SWITCHING CIRCUIT: Signals from the antenna connector are’ fed o the antenna switching circuit through low-pass filter consisting and £32 and C123:4n the PLL board: The antenna switching circuit employs a water wave switching circuit.
1F CIRCUIT The first IF signals from O3 are fed to the matched pair crystal filter Fi1, then (F amplifiers Q4 ~ Q6. The-amplified signals are fed to 1C1. 1CT s composed of the second local oscillator, second mixer; limiter amplifier, quadrature detector and active filter circuits. The second: local -oscillator oscillates 21.
LR This reduces: the current drain of the set, in the standby condition. When a signal is received, noise s suppressed by the signal and turns Q15 OFF and the regulator is turned ON and supplies regulated voltage to the AF power amplifier, and incoming signal can be beard from the speaker.
the bias voltage of 011~ Q14; This prevents:transmission of unwanted signals. POWER AMPLIFIER CIRCUIT The output signals from Q13 is fed to the power amplifier Q14 “and amplified to 1.5 WATS. in the: transmit ‘mode, D16 and: D17 are turned: D17 makes 131 has: high-impedance and D16 feeds tha signals 1o the: antenna through the low-pass filter, PLL CIRCUITS LOCAL: OSCILLATOR :CIRCUIT The crystal oscillator 07 [oscillates 45, 365556MHZ with (X2 for receive, with' X4 for simplex transmit, 47.
L2 1A the MHz duplex transmit mode, T+6V is applied to D11 through RE0, L1 2,116 and R68 and D11 is turned ON and selects X5. In the. ~5MH2 duplex transmit mode, T+5V is applied 1o D8 through R24, L10, 114 and R28 and Dis futurist ON and selects X3 When ‘the ‘operating frequency has a KHz ‘digit, cathodes ‘dre’ grounded through the SICHUAN SHIFT T switch, and ohe turned ON rewarding to the 'operating mode. Thus, one of L8 ~ 112 is-shunted ‘accordingly and. oscillating frequency.
REFERENCE: FREQUENCY. GENERATOR: CIRCUIT Reference frequency generator 1C3 consists of a crystal oscillator and & high speed divider. X1 oscillate Tate: at 6.
PG VEO CIRCUIT The VCO (Voltage-Controlled Oscillator) is 5 Cockpits circuit-using 02, and-oscillates in 140MHz range; The: osclilatorfrequency-is controlled by “5°DC voltage which ‘i supplied from the Loop Hitler 't var actor diode 1, In the receive mote; R5V is-applied to-D's anode through L3, and D2 is tarred ON and shiatsu G23. This the free-tin frequency of the VCO is Towered.
and 026 -is turned ON. Thus Q7 and O8 are turned ON-and THROB s actuated, and supplied.to the transmitter circuit. At the same time, T+6V turns Q13 ON, and the power supply voltage is applied 1o the MIC amplifier I the receive mode, 076 is turned OFE and the bias voltage of 010 ON.
