INTERCONNECTION

1. Connect the RF output of the exciter to the RF IN connector

on the rear of the AL-1500 with 50 ohm coax. Use any good

quality 50 ohm cable long enough to connect the amplifier to

the exciter. The amplifier uses a standard SO-239 female that

will mate to a PL-259 male connector on the cable.

2. Connect the existing station antenna system to the RF OUT

connector on the rear of the AL-1500 with RG-8 type coax.

This connection uses PL-259 connectors.

3. Use shielded audio type cable with standard male phono plugs

to connect to the RELAY jack on the AL-1500. This jack

has positive 12V DC open circuit and supplies

100mA of current when pulled to ground.

4. Connect a short ground lead from a good earth and RF ground

to the GND terminal.

5. The 12V connection on the rear panel provides 12V DC at 100

mA maximum to operate external dial lamps or accessories

such as the ATR-15 Antenna Tuner.

6. DO NOT CONNECT THE "ALC OUT" SOCKET ON THE

AMPLIFIER TO THE "ALC" SOCKET ON THE

TRANSMITTER UNTIL INSTRUCTED TO DO SO IN

THE TUNE UP PROCEDURE. This jack provides up to 20

Volts of negative voltage for transmitter gain control.
