1 INSTALLATION AND SETUP 5 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 100 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.
1 INSTALLATION AND SETUP 6 SETUP 1) Connect the RF-Input connector from the ALPIN 100 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 100. 3) Connect the PTT – Line from your transceiver to the RELAY jack of the ALPIN 100. The voltage on the Relay Jack is 12V and the current to ground is 11mA.
1 INSTALLATION AND SETUP 7 1.3. TRANSFORMER !!! ATTENTION !!! To avoid any damages, please remove the transformer before shipping. 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.
1 INSTALLATION AND SETUP 8 TOP SIDE CONNECTIONS The default configuration of the top side connections of the transformer is configured for 230V shown in the table below. The 2 cables from the fuse board are always connected to 1 and 4. Main board 8 7 6 5 4 3 2 1 High Voltage board side If the voltage of the power system is different from the default configuration you will have to change the position of the connector cables as shown in the table.
1 INSTALLATION AND SETUP 9 1.4. ANTENNA The ALPIN 100 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 100.
2 OPERATION 10 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.
2 OPERATION 11 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 100 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.
2 OPERATION 12 2.5. ELECTRONIC BIAS SYSTEM (EBS) only ALPIN 100 MK II The amplifier has an integrated EBS which can be activated and deactivated after switching on. The buttons UP and DOWN have to be pressed down while pressing the LINE switch on the backside. After this the display will show the message “EBS is on” or “EBS is off”. The status can be changed by doing this procedure again. The default configuration is an activated EBS. 2.6.
2 OPERATION 13 2.7. TUNING EXAMPLE You can find an example of the tuning procedure below. The LOAD TUNIG KNOB has to be rotated clockwise. While rotating the LOAD capacitor the CAP METER is close to the optimum tuning point. We are next to the optimum point. Just a small correction of LOAD and TUNE will be necessary to reach the point. Here, we have found the optimum point for the LOAD Capacitor. Now we can release the PTT and increase the drive power.
2 OPERATION 14 2.8. TUNE TABLE The table below shows the approximate settings for the TUNE and LOAD knobs on each band. These settings are not exact but they can give you a starting point for a faster tuning of the amplifier. Band 1.8 3.56 7.05 10.1 14.25 18.15 21.25 24.92 28.5 50.2 Tune 66 29 49 15 44 87 39 57 22 15 Load 85 48 81 30 38 81 56 54 39 14 These settings will vary from one amplifier to another. 2.9.
3 PROTECTION SYSTEM 15 3. PROTECTION SYSTEM This amplifier uses a very complex protection system. If an error occurs, the amplifier switches to standby or off mode and prints an error code to the display. In this way, the protection system is able to avoid a series of potential damages to the amplifier, but there is no reason to operate carelessly. 3.1.

5 EXHIBIT 19 Now you can remove the tube Before assembling the new tube it must be “conditioned”. Connect Pin 3 and Pin 7 to a power supply with 12V DC and adjustable current limiter. Supply each of the following currents for 3 minutes: 0,5 A / 1 A / 2 A / 3 A / max current ca. 4 A .
5 EXHIBIT 20 R 45 R 44 After assembling the new tube it would be necessary to adjust the plate current. Run the Alpin 100 without cover and connect to a transceiver. a. Setup of Poti R44 Without power from the transceiver in TX mode; adjust with R44 a plate current ( as shown in display from Alpin ) to 50mA. b. Setup of Poti R45 Slowly increase the power of the transceiver until the plate current jumps in the range of 200mA, then adjust with R45 the current to 180mA.
