wtKST Download and Setup

wtKST is a clean, simple user interface to the ON4KST online chats – but with some interesting features for Aircraft Scatter prediction.

wtKST was written by DL2ALF, the author of the AS prediction program AirScout and the two programs are linked. If AirScout is running in the background, wtKST will check the list of stations that are logged into KST and warn you about possible AS opportunities. Click on a callsign and the AirScout map will appear with more information.

(This note was first written because the usual download site at dl0gth.de was unavailable. It has come back now, but I’ll leave this page here.)

Note: wtKST is not ‘officially’ supported, so please do not ask questions to DL2ALF!

wtKST has one fixed-format screen, divided into four main areas:

  1. All the chat traffic (Left) – just like the official ON4KST chat interface (and just as unreadable when the bands are busy)
  2. A ‘filtered’ chat window (Lower Left) containing only the messages to and from yourself (like the KST2me filtered chat, but no setup required)
  3. Message input line (Top Left).
  4. KST login list (Right). If AirScout is also running, this is where the added info about AS opportunities will appear (see below).

wtKST is less configurable than either the ON4KST interface or KST2me by OZ2M – but the features you most want are already there, and easier to use:

  • Left-click on any other station on the login list, then type in your message at the top right.
  • Your personal message traffic will appear in the lower window (including your own outgoing messages if that option is selected – see below).
  • Right-click on any other station to see info, including distance and beam heading.

wtKST Setup

You should only need to do this once. – just follow these instructions.

  • Before you begin: you must already have signed up with the official ON4KST site to register your username and password.
  • Download: if the site at dl0gth.de is unavailable, here is a download link. Unzip the .zip file to a directory of your choice, and wtKST.exe should run.
  • In wtKST: click Options, choose the KST tab, and enter that same login information. Also enter your station info and other selections.

  • Next, click the Calls tab and choose which bands and stations you want to display.

  • Move along to the Airplane Scatter tab and check the two boxes below (use the default server settings). The bottom line lets you choose the minimum and maximum aircraft ranges you wish to know about.

  • Close the Options dialog and away you go –  wtKST is now your window into the selected KST chat.
  • To get the information from AirScout, open that program, and choose Options from the main screen. Select the Network tab and check Activate main server.

  • wtKST will now begin to highlight Aircraft Scatter opportunities with various stations in the right-hand columns. (The quickest way to populate these columns is to start (or re-start) wtKST after AirScout.)

In Action

The chat function has already been described. The rest of this section is about the extra AS-related features in the Right-hand window of the wtKST display.

NB: you will only see info about those stations that are logged into KST – don’t forget there are others too!

Same as with AirScout, purple blobs in the RH columns mean “AS possible now”, red means “possibly soon”, and brown/orange means “aircraft currently too low”. Bigger blobs indicate better opportunities (probably more planes).

Depending on your minimum and maximum distance settings (see above),  you may also see < which means “too close”, or > which means “too far away for AS”.

If you have further info about this area of the wtKST display, please post a comment here so I can update the blog.
