1. INSTALLATION AND SETUP
1.1. PACKAGE
When the amplifier is delivered to you it is packed in a cardboard box with styropor inlays.
Please handle the package with care. In case of damage you may need it for the ALPIN 200 to
be transported back safely.
1.2. CONNECTIONS
POWER CABLE
The green-yellow wire is a chassis safety ground and must always be connected to the safety
ground of the AC mains. (the AC-PLUG will not be supplied with the amplifier) The blue
and brown wires are the powerleads. Please take care that the groundlead be cut a bit longer
than the power leads (blue and brown) at installing the plug.
GND
Connect the ground stud of the amplifier on the rear panel to the grounding system. The wire
used should be of large diameter and run to a good earth ground.
RF INPUT AND OUTPUT
Use a 50 Ohm coax cable with PL259 plugs. Take RG 213 or any better antenna cable and
have a look on the antenna section on page no. 9.
CONTROL CONNECTIONS
Use a shielded cable with a Phono (RCA) connector from the Relay socket on the rear panel
to the transceiver socket, providing "ground on transmit".

5 EXHIBIT INSTALLATION AND SETUP 6

SETUP
1) Connect the RF-Input connector from the ALPIN 200 to the Transceiver Antenna Port
(TRX IN/Out).
2) Connect a suitable antenna or artificial load being able to handle the output power
delivered by the ALPIN 200.
3) Connect the PTT – Line from your transceiver to the RELAY jack of the ALPIN 200.
The voltage on the Relay Jack is 12V and the current to ground is 11mA.
4) For QSK Operation connect your KEYER to the “RELAY” Jack and connect the KEY
OUT jack on the rear of the ALPIN 200 to the KEY INPUT of your transceiver.
5) Connect the amplifier to the AC – Mains (230VAC) and switch on the MAINS
POWER SWITCH on the rear of the ALPIN 200.

1.3. TRANSFORMER
ASSEMBLING AND DISMOUNTING
It is very easy to assemble or to remove the plug-in transformer. There are only very few
connections and screws to other parts of the amplifier.
The Following parts have to be (dis)connected:
•6 pin plug socket to the high voltage board (only 2 pins connected)
•9 pin plug socket to main board and G1/G2 board
•2 pin plug socket to tube deck
•4 screws on the bottom of the box
!!! ATTENTION !!!
To avoid any damages, please remove the transformer
before shipping.

1.4. ANTENNA
The ALPIN 200 is able to match antennas up to an SWR of 1:3 (16..150 Ohms).
It is very important to take a suitable cable (RG213 or better) with a diameter as large as
possible for connecting the antenna.
All the rest ( i.e. : cable, antenna, balloon…) behind the RF output jack of the amplifier
should be able to resist 1 kW RF power. You have to make sure about this before you start
operating with the ALPIN 200. If you are not sure, please check the data sheets to avoid
damages.
1.5. COOLING SYSTEM
The cooling of the ALPIN 200 is realized by a high-quality blower. The air input port is to be
found on the back panel of the amplifier and the output outlet on the top side.
!!! ATTENTION !!!
It is very important to guarantee a free air flow from the
input- to the output side. Leave at least 20cm of free space
to both openings. Please free the air filter on the rear
panel from dust regularly.

2. OPERATION
2.1. FRONT PANEL
The front panel is divided into two parts: One for tuning and band switching (left) and another
for the visualization.(right)
The tuning part consists of a TUNE, LOAD and BAND knob.
In the visualization part there are three buttons: STBY/OPR, DOWN and UP for
standby/operate switching and display control. Besides, there are three LEDs: a red TX (lights
up when transmitting), a green OPR (lights up when in operate mode) and a yellow ATT
(lights up when the built-in attenuator is switched on).
The POWER switch is in the lower right corner of the front panel.
2.2. POWER ON
To start up the amplifier, use the LINE SWITCH on the back panel of the amplifier. Now you
will see the following message coming up on the LCD display at the front panel:
Now you can switch on the ALPIN 200 with the POWER SWITCH on the front panel. After
this, it will need another 2:30 min for heating up the tube. The LCD display will inform you
about the remaining time until the amplifier has reached STANDBY MODE with the following
two messages. They will alternate with a 5-second- cycle.

5 EXHIBIT OPERATION 10
ALPIN200 Manual © Copyright 2008 by Reimesch Kommunikationssysteme GmbH
While the amplifier is heating up, the protection system will monitor all the important data.
Please have a look at page 15 for more information.
2.3. STANDBY MODE
When the warming-up time is over, the ALPIN 200 will move to standby mode. Here you can
see the forward power for the first time, the reflected power, and the CAP meter. The fourth
row of the display is used to show individual and /or the most essential values of the
amplifier.
You may alter the displayed data with the UP and DOWN buttons next to the display.
The Following data will be shown:
•Forward power
•Temperature of the exhaust air
•Drive RF power
•Screen current
•High voltage
•Plate current
•Antenna SWR
•Reflected power
In standby mode the following values are measured: temperature of exhaust air, screen
current and high voltage. You can see all the values either in operate mode or in transmit
mode.
2.4. OPERATE MODE
To enter the operate mode press the OPR/STBY button. After this, the green OPR LED will
light. Only in this mode you will be able to transmit.
