Contest definitions

A contest definition (a .ctd file) tells ShackAssistant what a contest asks for: the exchange, the points and the multipliers. Find the one for your contest here and download it. Some contests need a section list or a call history as well, so each download is a small zip with everything that belongs together.

These definitions come from the N1MM community, and the file shape is theirs - an INI file with the key names they settled on. ShackAssistant reads that shape as a .ctd, so the work that went into these files is not thrown away.

How to use one

Three steps

  1. Download the zip for your contest from the list below.
  2. Unzip it into Documents\ShackAssistant\CTD. You get a folder with the definition and anything that goes with it.
  3. In ShackAssistant, choose File → New logbook → contest log and pick the contest from the list.
The format

Where these come from

Contest definitions are written once, by people who read the rules carefully, and then shared. Thousands already exist. Inventing a new file shape would mean all that work again - every organiser's rules typed out twice - so the shape stayed: an INI file with the same key names. The definitions below are the ones that were already out there, checked and packed.

What is gone is the requirement that another program be able to read what ShackAssistant writes. That is what lets the scoring say things the old shape could not - a score that ADDS a bonus instead of multiplying by it, or points by distance - and those are exactly the two that the Dutch contests needed.

Check the date and the rules of the contest before you start: organisers change their rules, and a definition is only as up to date as its version. More about contest logging is in the contesting guide.
