* 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
1.
Power Level Meter
Accurate output power can be read with a built-in precision
directional coupler.
2.
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.
3.
Output Power Level Switch (HI/LO)
Output power can be reduced by one-half at the "LO"
position.
4.
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.
5.
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.

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

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.

DC Power Leads: Red for positive, black for negative.
* Setting and Operation
1.
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 (-).
2.
Using a coaxial jumper cable (50 ohm type), connect "TX
(N)" of the rear panel to the Antenna connector of the
transceiver.
3.
Connect the antenna cable to the "ANT (OUT)" at the rear
panel.
4.
The impedance condition of the antenna used (or SWR)
must be checked to be 1.5 or less by using SWR meter.
5.
Operating the transceiver to "transmit", H L-82V is also
automatically operated to transmit.

6.
Operating the transceiver to "stand-by (or receive)", H L-
82V is automatically switched to "receive" state.
7.
Turning the DC power switch off, the receiving and trans-
mitting signals to and from the transceiver will bypass
the HL-82V.
8.
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
1.
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.
2.
Since the expensive and precision components are used
throughout, please do not touch or trim the internal parts.
