Why don't I see any packet spots in Win-Test?

Win-Test provides a separate program called wtDxTelnet to connect to packet cluster nodes over the Internet, and to other devices (TNCs or CW Skimmer). wtDxTelnet then shares these spots with one or more copies of Win-Test via local TCP/IP broadcast messages.

Both Win-Test and wtDxTelnet have to be configured to use the same broadcast address and port number, or else packet spots will not be seen by Win-Test, even if they are displayed OK by wtDxTelnet.

  • If you are using a single computer for both logging and cluster connections (e.g. single-op assisted class), follow the procedure for Configuring wtDxTelnet (single-op environment). It explains how to use the "loopback" address so that all communication between Win-Test and wtDxTelnet stays inside the computer, instead of going over the LAN.
  • If you are using multiple networked computers, and want to share spotting information between them (e.g. multi-single, multi-multi), follow the procedure for Configuring wtDxTelnet (multi-op environment). You only need to run wtDxTelnet on one computer in your network, not all of them.

In both environments, it is essential to configure the same broadcast address and port number in both programs.

Win-Test will automatically filter packet spots based on your current entry class (CW, Phone, Mixed), and the defined band plan.

Why do I see many duplicate packet spots in Win-Test?

If your PC as both a wired Ethernet port and a wireless LAN (WLAN) adapter active and connected to the same network, disable one of them.

Only run one copy of wtDxTelnet on the network.

When using Ethernet networking, do not select Network on any serial port. When using rig control, make sure that the proper serial port is marked Radio 1 or Radio 2, and configured properly.

Can I make wtDxTelnet start automatically when I start Win-Test?


  1. In Win-Test, select Options | DX Cluster ... | Local wtDxTelnet | Start/stop automatically
  2. In wtDxTelnet, select Options | DxCluster Properties and check both:
    • Autoconnect at startup
    • Try to restore connection automatically

Can I connect to more than one cluster or to both CW Skimmer and a cluster?

Yes. Just start another wtDxTelnet window (Start | All Programs | Win-Test | wtDxTelnet), but specify a different hostname / DX Cluster. You need to run one copy of wtDxTelnet per remote cluster, TNC, or CW Skimmer.

For CW Skimmer running locally, use:

  • Hostname/IP: localhost
  • Port: 7300

Can I make multiple copies of wtDxTelnet start automatically and connect to different clusters?

No. Win-Test does not support starting more than a single copy of wtDxTelnet automatically, but you can start as many copies as you need manually by adding a wtDxTelnet shortcut to your Windows desktop or to your Windows "Quick Launch" bar.
