WaveNode WN-2 General Description

The WaveNode WN-2 is the perfect power and SWR monitor system for the advanced ham, remote controlled stations, contest stations and commercial applications where exact power and SWR measurements are crucial.

The Basic Station Monitor consists of the WN-2 signal processing unit and in-line coax sensors. The WN-2 contains all signal processing for up to four coax in-line sensors, and no calibration is necessary. An additional input is available for monitoring D.C. supply voltage and current (< 16 volts and < 25 amps). The interface to the computer is made via USB port.

The WN-2 can run stand-alone, or run in conjunction with your PC for simultaneous viewing of all four channels. Powerful 16-bit RISC processor with 12-bit A/D converter allows fast sampling and data transfer via USB port. Local selection on the unit of Channel number, SWR reset, and input/output port monitoring.

WaveNode WN-2 Main Features

  • Simultaneous monitoring of RF power/SWR on four separate coax sensors. Add sensors before and after the amplifier, add sensors at the antenna to measure SWR and power at the feed point.
  • Calculates SWR, peak, and average power for display on the built-in LCD display. Bargraph displays of peak power are shown when the RF power exceeds 2 watts.
  • SWR protection relay (User selectable ports and level)
  • Full-speed USB computer interface on all products.
  • 16-bit RISC microprocessor, 12-bit A/D converter, and precision peak/average detection circuitry for each sensor.
  • 40 Khz sampling of the RF envelope provides a digital Oscilloscope view of the modulation envelope.
  •  Spectrum Analysis monitors the data content and bandwidth of the modulation speech or data stream. Monitor Inter modulation and splatter real-time as you operate.
  • Additional monitoring circuitry is provided for station DC voltage/current.
  • Four digital outputs allow monitoring and control with remote PC.
  • Four additional analog inputs allow real-time monitoring on the local LCD display or remotely through USB interconnect to a host PC.
  • Relay provided to trigger on excess SWR for equipment protection.
  • All data viewing and control can be done locally or remotely via PC.
  • Voice and Tone announcing of power and SWR for visually impaired operation.

    I recently installed the WN-2 at my contest station (SE0X). The purpose was to monitor my 144 MHz amplifier while operating remote. It works great for this task alone!

    Having the option to use up to 4 sensors is a big benefit! I have also installed a second sensor for one of the two HF stations on site, and a third sensor is coming for the other HF station. This way I can have full control over signals when operating SO2R or Multi.

    The WN-2 system comes with several software apps. The one I like the most is the “MiniPanel” which displays Power and SWR for all four sensors in a horizontal bar. It is the perfect way to get only the info needed with minimal screen real-estate used. And by dragging the right edge I can limit the size of the window to show only the most left one, two or three sensors. Cleverly simple!
