Version 3.1.6 New features

  • A default CWOps roster is now included with SkookumLogger, used for self-adjudication (see Help). Thanks W2RU.

  • Updated IRTS Counties calendar, and scoring for Inside entrants. Thanks GØDVJ.
  • Updated Polish DX Contest (SPDX) information, submission rules now require using web site; emails are rejected.
  • Updated Florida QSO Party log submission and rules URLS.

Bug fixes

  • For NEQP entrants inside New England, working a 7QP or INQP rover is a dupe when they change counties. In 7QP, the same rover in difference states is a dupe but may be a state multiplier. Thanks K1KI.
  • The & (sent exchange) CW message token now excludes the signal report, as documented. For QSO parties where the sent exchange is the county, the & token can be used to send the county as part of any message. Thanks K1XX and WA1Z.
  • OK-OM DX Contest SSB was requiring CW mode for QSOs. Thanks NK4O.
  • Florida QSO Party Inside Florida was mishandling QSOs with other Florida stations.
  • Ontario QSO Party start time was 12Z instead of 18Z.
