Web control four rotator, fifteen relays and many other features that come from Raspberry PI RemoteQTH server.

Main functions:

  • Control the four rotators using the light buttons,
    rotary encoder and with a two-line display for each rotor.
  • Same control remoted via web interface or telnet
    – only click to map and confirm rotating.
  • Rotator module can directly control the motor of the rotator
    • DC version of the phase-change
    • AC version switching CW or CCW winding

    Or you use the relay contacts to control your control box.

  • 24 freely configurable relay (15 in model B) (first used for server power on/off)
    as single pole, single throw or single pole, more throw
    – suitable for switching antennas.
  • GPIO interface power board associating functions
    • Relay switching from GPIO
    • DC/DC converters power supply 5V for Raspberry PI
    • DC/DC converters power supply 5V for four arduino rotators module.
      Turns ON the first GPIO output.
    • Available four DC/DC converters – custom voltage power supply for each motor of rotator. In the range of 2 to 37V an max current 3A.
    • Include A/D converter for four voltage measurement
    • Expand I2C bus – available connect next temperature or voltage sensors
  • All in simple 2U Rack case.
    • Case made to measure from 2 mm aluminium.
    • Laser engraving plastic front panel.
  • Each the rotator unit interface, based on arduino (code by K3NG) contains:
    • LCD.
    • Lighting button (CW, CCW, Start).
    • Preset encoder.
    • Three relay (CW, CCW and Brake).
    • Arduino nano module.
    • Ready for AC and DC rotators.
    • Analog input.
    • 5V power voltage.
  • Server requires a DC power supply ranging from 9 to 40 volts.
    Voltage is dependent to the rotator, if we are powered motor directly from the server.
  • If you have a rotator AC motor, the server has terminals
    for connecting the AC voltage for each rotor separately.
  • Another server utilization

  •  Export USB/serial interface to IP.
    • CW keying from web interface.
    • Connection RaspiCam Webcam.
    • Access without public IP adress (n2n vpn).
    • Switching relay by TRX frequency using Band decoder function.
  • Necessary components
    • Rack case.
    • Rapsberry PI + 4GB SD card with RemoteQTH server.
    • GPIO interface power board.
    • Relay board.
    • Four arduino rotator interface.
    • Usb hub with external power supply.
    • DC power supply 9-40V dependency to max DC rotator voltage.
    • AC power supply if AC rotator instaled.
