Operating

Modes: CWSSBFM
Bands: 2m
144 MHz band only.
Exchange: RS(T) + serial number from 001 per band + 6-character locator (e.g. 59003 JO20DB)
Logs: EDI
Who can enter: Anyone, anywhere.
Not encoded as an entity list: the sponsor limits entry to Region 1 ('All licensed radio amateurs in Region 1 may participate in the contest'; special high-power licences enter as check logs only), and enumerating every Region 1 entity is not done here. Stations elsewhere cannot enter but may be worked.

Where this comes from

Checked against the sponsor: Yes. The rule on this page was read off IARU Region 1 VHF+ Committee's own published rules. Link last confirmed 2026-10-15.
What the source says: VHF Handbook 10.03 (https://www.iaru-r1.org/wp-content/uploads/2026/02/VHF_Handbook_V10_03_final.pdf), section 'RULES IARU R1 50/70 MHZ, 145 MHZ AND UHF/uW CONTESTS': 'IARU Region 1 145 MHz contest will begin on the first Saturday of September'; 'Each contest will commence at 14:00 UTC on the Saturday and end at 14:00 UTC on the Sunday.' Sponsor's hub calendar: 2026 Sep 5-6; 2025 Sep 6-7 per the same page's archive. Categories: SO, MO, SO-LP, MO-LP, 6H (Low Power is 100 W PEP with one antenna system). Read 2026-10-15.
Recorded caveats: Log deadline is not a fixed offset (EDI 'no later than the first Wednesday following the contest weekend at 23:59:59 UTC'), so log_deadline_days is not encoded.

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

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=iaru-r1-145mhz

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.
