JT Skimmer

Quick Start

Installation

• Click on the Download button above and download the JTSkimmer.zip file.

• Run JTSkimmerSetup.exe from the zip and follow the instructions.

• The setup includes the latest version of OmniRig. If you already have OmniRig installed and it works fine, uncheck the OmniRig option:

  

Configuration

• Connect your SDR receiver to the computer.

• Start the program. Click on Tools / SDR Devices in the menu. This dialog will open:

  

• Click on a radio button to select the SDR that you want to use.

• Select the desired bandwidth and center frequency. The settings in the screenshot cover the first 360 kHz of the 10 m band. Click on OK.

• If all is good, the waterfall in the Band View panel will start. Click on this button and ajust the waterfall brightness and contrast:

  

• Click on the Add Receiver button on the toolbar and add one or more receivers.

  

• On the receiver panel:
  • click on the Speaker button to listen to the receiver
  • click on the VAC button to send the audio to the Virtual Audio Cable
  • click on the OmniRig button to tune your transceiver to the frequency of the receiver
    

• Click on the Settings button to open the Receiver Settings dialog:

  

• Enter the receiver frequency, select the mode to decode or No Decoding. Click on OK. JT Skimmer will start decoding the selected mode on the selected frequency.

• Click on Tools / Settings in the menu to open the Settings dialog.

  

• In the Message Distribution section specify what the program will do with the decoded messages:
  • Save to a file
  • Serve as DX spots from the built-in Telnet cluster
  • Send UDP packets in the WSJT-X format to notify other programs, such as
    • GridTracker, to show the spots on the map;
    • N1MM, for two-way data exchange and callsign highlighting ( screenshot).
  • Send to the PSK Reporter web site
    
    

• If desired, enable the I/Q Output option. This will send out UDP packets with I/Q data in the TIMF2 format understood by LinRad, QMAP and MAP65 programs ( screenshot).

• Minimize the JT Skimmer window. It will disappear from the Task Bar and hide in the System Tray:
