U20352 Used Autek Research WM 1 Computing Meter SWR/Watt Meter

U20352 Used Autek Research WM 1 Computing Meter SWR/Watt Meter

Overall Condition: Used, excellent physical condition! Shows clean metal chassis and faceplate panel with no cosmetic issues or defects. The dual analog meter movements, backlit displays, front toggle switches, and remote RF sensor box are all clean and fully functional. Comes complete with the external RF sensor unit, interconnecting cable, and 12V AC power supply adapter.

The Autek Research WM 1 is a classic computing SWR and peak/average reading RF wattmeter designed for continuous HF/VHF power monitoring. Unlike traditional dual-needle meters that require manual calibration knobs or manual scale adjustments to read SWR, the WM 1 uses active analog computing circuitry to display SWR continuously and automatically, regardless of transmit power level changes.

Equipped with a remote RF sensor box fitted with dual SO-239 connectors, it measures forward power across three selectable ranges (20W, 200W, and 2000W) in both Average (AV) and Peak (PEAK) modes. High-contrast green meter backlighting ensures easy readability in any shack environment.

Condition Breakdown

• General: Pre-owned, excellent physical condition with clean surfaces throughout

• Meter Face & Backlighting: Dual SWR and PWR meter glass windows and green scale backlighting are bright and clear

• Front Controls & Toggle Switches: OFF/ON, AV/PEAK mode, and WATTS range (20 / 200 / 2000) switches operate smoothly

• Remote Sensor Box: Aluminum sensor housing with IN (Transmitter) and OUT (Antenna/Tuner) SO-239 coax connectors and cable assembly are clean and solid

• Power Supply: Includes 12V AC wall adapter for meter illumination and internal computing circuitry

Key Features

• Automatic Computing SWR Readout: Computes and displays SWR automatically without requiring manual "CAL" knob adjustments

• Dual Simultaneous Analog Meters: Dedicated SWR meter and PWR (Wattage) meter allow real-time monitoring of power and antenna match simultaneously

• Three Selectable Power Ranges: Measures 0–20 Watts, 0–200 Watts, and 0–2000 Watts PEP/Average

• Peak and Average Reading: Mode switch toggles between Average power and Peak Envelope Power (PEP) for SSB voice accuracy

• Remote RF Sensor Module: Keeps heavy coaxial cables off the desk while allowing convenient meter placement
