Quick Start Guide:

A more complete guide to the installation is featured later

1. Connect the RTX input connector e to transceiver

with 50 Ohm patch cable

2. Connect the ANT Output f of the Amplifier to ATU /

VSWR Bridge, (If required), and then the Antenna (50
Ohm load Impedance)

3. Connect the PTT cable from the transceiver to the

amplifier. PTT is Active low. (The MLA100 will work
without the PTT connected but it is recommend to
use it for CW and SSB modes).

4. Connect the DC power Cable to the amplifier c to a

suitable 13VDC (± 1V) Power Supply or Auto Battery.
Pay attention to the correct polarity

5. Make sure that the amplifier is switched off [

6. Adjust the Transceivers RF output power to 5W, if it

is capable of more than 5W output.

7. Test that the antenna connected is suitable for the

band required, if not use an ATU to match the an-
tenna with the amplifier switched off.

8. Switch on the Amplifier, press and hold [ 2 secs.

9. The amplifier will automatically select the correct

band filter on the first transmission.
