* General Information

The HL-82V is a high power linear amplifier designed for

the 144MHz amateur band operation. It features a stable and

powerful amplifier along with excellent linearity which is

especially effective on SSB mode. The built in high-gain receiver

pre-amp used in the HL-82V enables you to enjoy more com-

fortable dX QSOs. In addition the RX pre-amp can be inde-

pendently operated.

* Features

Power Level Meter

Accurate output power can be read with a built-in precision

directional coupler.

Low Noise MOS FET RX Pre-Amp

The latest MOS-FET with high gain and excellent cross

modulation characteristics, amplifies even a very weak

receiving signal. This preamp can be independently operat-

ed, when only receiver amplification is needed.

Output Power Level Switch (HI/LO)

Output power can be reduced by one-half at the "LO"

position.

FM/SSB Mode Switch

The time constant of the COX (automatic send-receive

switch) is changed in relation to the mode, in "FM", the

change from "TX" to "RX" is made instantly and in

"SSB", with some delay.

Terminal for Remote Send-Receive Control

A remote control terminal is accomodated at the rear panel.

This enables a smooth and instantaneous change-over es-

pecially on SSB mode, when two leads are wired to the

remote control terminal of the transceiver.

DC Power Switch: ON/OF F

(3)

RX Switch: Receive pre-amp switch, ON/OFF. For inde-

pendent RX pre-amp operation turn this switch on with

"POWER" switch off.

(4)

MODE Switch: SSB/FM mode select, at "SSB" the change-

over from TX (send) to RX (receive) is made with some

delay of approx. 1 second, and at "FM", the change is

made instantly.

(5)

Output Power Meter: Monitors output level

(6)

Power Level Switch: Selects either high or low output

level, at "HI", full power is delivered and at "LO", one

half of the full output.

Remote Control Terminal: Although HL-82V has an auto-

matic COX send/receive switch, HL-82V can also be con-

trolled remotely by the transceiver. (See item 8. of opera-

tion). Two lead wires should be connected to remote

output of the transceiver, which becomes "make" or

"short" when transmit.

Fuse Holder: 15A

DC Power Leads: Red for positive, black for negative.

* Setting and Operation

Connect DC power leads to the DC power supply and/or the

battery, red lead to the positive (+) terminal and the black

one to the negative (-).

Using a coaxial jumper cable (50 ohm type), connect "TX

(N)" of the rear panel to the Antenna connector of the

transceiver.

Connect the antenna cable to the "ANT (OUT)" at the rear

panel.

The impedance condition of the antenna used (or SWR)

must be checked to be 1.5 or less by using SWR meter.

Operating the transceiver to "transmit", H L-82V is also

automatically operated to transmit.

H L-82V

Operating the transceiver to "stand-by (or receive)", H L-

82V is automatically switched to "receive" state.

Turning the DC power switch off, the receiving and trans-

mitting signals to and from the transceiver will bypass

the HL-82V.

For a remote control operation by the transceiver, remove a

cover of the plug, and solder the two leads to pins 1 and 3.

A lead connected to pin 3 must be wired to ground pin of

the remote control terminal of the transceiver. The other

lead connected to pin 1 must be wired to pin of the trans-

ceiver, which becomes "make" or "short" at transmitting.

(See page 1 also for connection.)

* Caution

Nominal DC power supply voltage of HL-82V is 13.8V,

and HL-82V is designed to work from 12V battery system.

Please do not apply DC voltage over 15V, or the internal

transistor circuitry will be blown off.

Since the expensive and precision components are used

throughout, please do not touch or trim the internal parts.
