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.

Page 2: Front / Rear Panel Description
Introduction: Front Panel The MLA100 is a wideband HF & 6m amplifier capable of 100W HF, (80W 6m), output from 5W input drive, suitable for any of today’s QRP transceivers. It features automatic / manual band selection, rapid switching between receive and transmit by PIN diode RF switching, making it suitable for all modes of narrow band modulation and QSK operation. -
Page 3: Operation
Before the amplifier is switched on, the output power of the drive radio should be adjusted cor- The MLA100 may be used for all of the common narrow band transmission modes such as rectly if it is capable of outputting a power greater than 5W. This may be done with the ampli- SSB, CW,AM,FM, SSTV and data modes etc. - Page 4 Input drive and power output: The amplifier should give full output with approximately 5W input on the HF bands and 8W on 6m band. Excessive input power should be avoided and the amplifier should always be oper- ated in a responsible manner. If excessive input power is used the amplifier will signal an er- ror ] and disable itself for a short period of time before resetting.
