Bands, modes and exchange

ARI International DX Contest

Modes
CW, SSB, and RTTY
Bands
160 m, 80 m, 40 m, 20 m, 15 m, and 10 m
Length
24 hours
Exchange
Italian stations send signal report and province abbreviation (59 MI); everyone else sends signal report and serial number. Everybody works everybody, except Italy to Italy.

How the date is set

The first full weekend of May, from Saturday at 12:00 UTC, for 24 hours.

RTTY is not used on 160 m. The 2026 rules were not found online; the rule is the one ARI published for 2022-2023.

Bands during the contest

It runs on 160 m, 80 m, 40 m, 20 m, 15 m, and 10 m.

It runs in CW, SSB, and RTTY, so both the CW and the phone segments are busy.

The WARC bands (30, 17 and 12 m) stay contest-free by IARU agreement: that is where DXpeditions and quiet QSOs go.

Taking part

You do not need to be a contester to hand out a few points: answer a CQ, give the exchange exactly as the rules ask, and log the contact. Most organisers take logs in Cabrillo format through an upload page, with a deadline a few days after the end, and even a short log helps the checking. Check-logs are welcome too.

It is one of the 31 contests in the HamQSO calendar, and the feed adds its next editions to your calendar.

Official rules

The rules are published by ARI. They change from year to year: read them before you send a log.
