Where this comes from

Checked against the sponsor: Yes. The rule on this page was read off SRR's own published rules. Link last confirmed 2026-10-15.
What the source says: srr.ru 2026 regulation PDF (identical wording in 2024): 'Соревнование проводится ежегодно во вторые полные выходные мая'; 2026: 12:00 UTC 9 May to 11:59 UTC 10 May. Cabrillo web upload only, 10 days after. Read 2026-10-15.
Recorded caveats: Bands are stated as 1.8-28 MHz without the WARC bands. The rules' home site cqm.srr.ru returned HTTP 500 when read. /M and /MM are not multipliers.

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=cq-m-dx

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.
