UBA PSK63 Prefix Contest

UBA PSK63 Prefix Contest 2026

1. Date

10 january 2026, 12:00 UTC until 11 january 2026, 11:59 UTC.
(every year the 2nd weekend of january)

2. Participants

Participation is open to all radio amateurs world wide in possession of a valid licence and to all SWL's.
With regard to participation in activities of a competitive nature (contests, ARDF competitions, obtaining awards, etc.), the UBA Governing Body has decided that the UBA will axe the measures taken by various IARU sister associations and regular sports organisations. This means that, until further notice, radio amateurs from the Russian Federation and Belarus will be excluded from participation.
The IARU stipulates that politics and radio amateurism should not be out of sync. The UBA's decision to exclude Russians and Belarusians from competitive activities organised by it is rooted in the fact that we judged that the issue is a moral one and not political.
QSOs with the Russian Federation and Belarus therefore count for 0 QSO points and 0 points for multipliers.

Logchecking  will be computerized with as few manual interference possible.
Try to be sure all callsigns and exchanges are logged correctly by both stations.

QSO neither counted nor penalized for the following:

• Incorrectly logged calls (Bad Call)
• Incorrectly logged exchanges
• QSO is not present in the other station log (NIL)
• QSO time in entrant's log and other station's log difference is more than 5 minutes. So make sure your computer clock is correct.
• QSO bands or modes in entrant's log and other station's log differ. Both stations will lose the QSO.
• Dupe QSO's.
• If no log is received, a QSO will only count for points if the callsign appears in at least 5 other logs.  If no log was received from the worked station it only counts for points if the callsign was found in at least 5 logs.  For a worked station where no log was received and the noted report is greater than 5, no points are awarded.
