Introducing Wi-Fi Antenna Switch & Power/SWR meter - WS16

WS16 allows you to power-up your station, switch antennas, and monitor your transmiting power / SWR locally or remotely using a WEB browser in SO1R, SO2R or M2 station configuration.

Together with the WRC rotator controller you can remotely control and monitor your station.


  • 2.4GHz WiFi 802.11n network interface to minimize wiring and RFI.
  • Listens to UDP RadioInfo packets sent by N1MM+, DXLabs and other logging software to extract radio operating frequency and select antenna. Any transceiver that can be interfaced with N1MM+ will work.
  • Connects directly to Flex 6x00 transceivers – no PC needed for remote control and monitoring.
  • WEB server to display operating Frequency, Power / SWR and select from available antenna on that band, remotely on PC / MAC or tablet. WEB pages are fully customizable.
  • Measure and display Transmitting power and SWR for two amplifiers with optional TM Power sensors.
  • 16 digital outputs, each can provide 12V / 0.5A.
  • Compatible with DX Engineering, RemoteQTH 2x6, 2x8 and other antenna switches.
  • In SO2R or Multi-2 configuration, WS16 will serve a separate WEB page for each radio.
  • Avoids collisions in SO2R / M2. Prevents switching two TRXs on same antenna. First radio wins.
  • Opto-isolated inputs (KEYx) to prevent Antenna hot-switching. Will not switch until KEYx is released.
  • ONAIR solid state relay 36V/0.5A that can be used to switch Flex 6x00 On/Off or control the station main power relay.
  • Provides a fast websocket interface for Node-RED integration. Flows are uploaded at nodered-hamradio
