Where this comes from

Checked against the sponsor: Yes. The rule on this page was read off ÖVSV's own published rules. Link last confirmed 2026-10-15.
What the source says: oevsv.at contest page and the rules PDF (Aktivitaetskontest-Adaption-der-Kontestregeln-ab-2022.pdf): 'Termine: jeder 3. Sonntag im Monat (12 Bewerbe pro Jahr)'; 'Betriebszeit: 07:00h UTC bis 13:00h UTC, Ausnahme im Juni: 07-15h UT'. The page's own 2026 list: 18 Jan, 15 Feb, 15 Mar, 19 Apr, 17 May, 21 Jun, 19 Jul, 16 Aug, 20 Sep. Modes: all analogue modes (CW, SSB, AM, FM). Eligibility: 'Alle Inhaber einer gültigen Amateurfunkbewilligung'. Log within 8 days of the contest, 23:00 UTC, uploaded at mikrowelle.oevsv.at. Read 2026-10-15.
Recorded caveats: June is the one month on a different clock: 0700-1500 instead of 0700-1300, encoded with month_times. The page's dated list prints the June 2026 running as '07:00 - 14:59 UTC' while the rules text says 15:00; the rules text is encoded. No repeaters or transponders, no /M, each station once per band.

Something wrong? How to report it — a link to the sponsor's own page is all it takes.

Take it with you

Add to Google Calendar Subscribe (iCal)This record as JSON

Add to Google Calendar puts the next running in as a single event. It is one event, not a subscription — come back for the one after it, or use the feed below.

Subscribe (iCal) carries this contest's runnings for the next twelve months as UTC instants and keeps them current. Apple Calendar, Outlook and Thunderbird take this address directly. Its identifiers are stable across deploys, so re-subscribing does not duplicate anything: https://contestclock.com/api/ics?id=oevsv-activity

Google has no working one-click subscribe. Paste that address into Settings → Add calendar → From URL. Google then polls it on its own schedule, often 8–24 hours, and that cannot be forced — so use Add to Google Calendar above if you want the next running in your calendar now.
