SRR Cup on Digital Modes (RTTY)

The Russian Amateur Radio Union's RTTY cup, run as two four-hour rounds on a September weekend.

Rules at srr.ruThe rules are the sponsor's. This page holds the dates and the facts.

When it runs

Dates set by the sponsor each year (no derivable rule)

1500Z → 1859Z

Times are UTC, as the sponsor states them.

The sponsor announces these dates a year at a time and there is no rule to derive, so this calendar holds only the years they have published: 2025.

Next runnings

The sponsor sets this date each year rather than by a rule, and has published through 2025. Years they have not announced are absent rather than guessed.

Where this comes from

Checked against the sponsor: Yes. The rule on this page was read off Russian Amateur Radio Union's own published rules. Link last confirmed 2026-10-15.
What the source says: srr.ru regulation 'Kubok SRR po TSVS 2025 RTTY': two rounds, Saturday 2025-09-20 15:00-18:59 UTC and Sunday 2025-09-21 06:00-09:59 UTC, RTTY45, 80/40/20/15/10 m, 8 counted hours; groups A1/A2/B (Russian stations) and C1/C2 (foreign). Read 2026-10-15.
Recorded caveats: DATES ARE STATED PER EDITION; THE SPONSOR PUBLISHES NO RECURRENCE RULE. Only the dates the sponsor has actually published are encoded (20 and 21 September 2025); a year it has not announced yields nothing rather than a guess. If a stated rule turns up, this record upgrades from manual. No 2026 edition was seen on srr.ru.

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