The Drake SCHEMATICS operation manual provides detailed instructions for the installation, operation, and troubleshooting of the MN-2000 Antenna Matching Network, including how to connect the device to transmitters and antennas, adjust tuning controls, and monitor VSWR and power output. It also includes guidance on using the bandswitch, resistive and reactive tuning controls, and antenna selector switch to ensure optimal performance and match transmitter output to various antennas.
Manual Overview
The Drake MN-2000 Antenna Matching Network is designed to optimize transmitter performance by matching the impedance of the antenna to the transmitter, ensuring efficient power transfer. It can handle up to 2000 watts PEP and is equipped with controls for resistive and reactive tuning, VSWR calibration, and antenna selection. Troubleshooting involves using the built-in wattmeter to measure VSWR and power output, helping to diagnose issues by comparing transmitter output into the antenna and a dummy load. Error codes are not specified, but the manual emphasizes careful calibration using the push-to-set-release control for VSWR and the forward watts-VSWR switch. For calibration, the bandswitch selects the appropriate capacitors and inductors for each frequency band, while resistive and reactive tuning controls adjust the impedance match. The unit includes board-level guidance for connecting the transmitter and antennas, with specific instructions for using 50-ohm coaxial cables and grounding. Proper installation and operation are crucial for maintaining performance and warranty coverage.

Controls & Indicators
The front-panel controls of the MN-2000 include the bandswitch, resistive tuning, reactive tuning, push to set-release for VSWR, forward watts-VSWR, and antenna selector switch.
Installation / Setup
The installation of the MN-2000 involves several key steps. First, upon unpacking, inspect the unit for any damage and retain the packaging materials for potential future use. The device should be placed in a location where the control knobs are easily accessible. For connections, use a 50 ohm coaxial cable to connect the RF output of your transmitter or linear amplifier to the TRANSMITTER connector on the MN-2000. The coaxial line from the antenna should be connected to either the antenna 1 or antenna 2 connectors. Ensure the MN-2000 is the last component the outgoing RF signal passes through before reaching the antenna feed line. Finally, bond the GROUND post of the MN-2000 to the station ground with a short piece of heavy braid.
Operation
The operation of the MN-2000 involves several controls and procedures. The bandswitch is used to select the fixed capacitors and inductors needed for each band. The resistive tuning control adjusts the resistive component to match the antenna impedance, while the reactive tuning control tunes out the reactive component. The push to set-release for VSWR control varies the sensitivity of the meter circuit and calibrates the meter. The forward watts-VSWR switch allows the meter to read either forward power in watts or VSWR, with two ranges provided: 200 and 2000 watts full scale. The antenna selection switch selects either of two antennas to be matched by the MN-2000, and in the direct positions, the tuning network is removed to observe the VSWR directly on the meter.
