UBA DX Contest - Rules

UBA DX Contest 2023

The UBA has the honour to announce that this contest will be challenged under the Patronage of the EC Commission, responsible for Communication, Information and Culture.
The 36th EUROPEAN UNION TROPHY will be awarded to the highest scoring Single Operator High Power and the
Single Operator Low Power EU member station from both the CW and SSB competition.

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.

1 - Purpose

To contact as many Belgian and other amateurs as possible and to provide a way to work the Belgian awards.

2 - Periods

SSB - January 28 - January 29, 2023 (starts every year on the last Saturday of January).
CW - February 25 - February 26, 2023 (starts every year on the last Saturday of February).
From 13:00 UTC on Saturday to 13:00 UTC on Sunday.

  • Stations in category D are limited by the "10 minute" rule. A run station must stay at least 10 minutes on a band before changing bands.

  • QRP SSB maximum 10 Watts output, CW maximum 5 Watts output.

4 - Bands

Bands to be used: 80, 40, 20, 15 and 10 meters. The IARU band plan and the IARU Contest prefered frequencies.  WARNING: Failure to comply with the bandplan may result in disqualification

5 - Contest call and exchange

  • Stations on Belgian territory: RS(T) + serial number starting with 001 + the abbreviation of the UBA section (e.g. 59001 ACC). The section is an integral part of the report and must be mentioned in the log. Stations which are not members of the UBA use XXX. National UBA stations (ON4UBA, ON4DIG and ON4YLC) use UBA as their section.
  • DX stations: RS(T) + serial number starting from 001.

6 - Scoring

Stations with QTH in Belgium
  • A QSO with a Belgian station 1 point,
  • A QSO with a station in one of the DXCC countries of the European Union at the time of the contest 2 points.
  • All other QSO's 3 points.

Stations with QTH outside Belgium
  • A QSO with a Belgian station 10 points,
  • A QSO with a station in one of the DXCC countries of the European Union at the time of the contest 3 points.
  • All other QSO's 1 point.
An additional bonus will be given depending on the percentage of QSO s with Belgium on your total valid QSO's. Example: 50 QSO's with Belgium (500 QSO points) on a total of 320 QSO's means 15.6 % of QSO's with Belgium and will give you (15,6 % of 500 Belgian QSO points) an extra of 78 QSO points on your total QSO points. This calculation will be done after the log checking.

7 - Multipliers 

Stations with QTH in Belgium
All DXCC countries once on each band.

Stations with QTH outside Belgium
Once on each band.
  • All UBA sections. XXX used by non-UBA members does NOT count as a multiplier.
  • All Belgian prefixes such as ON(x), OOn, OPn, OQn, ORn, OSn, OTn (x1-9)(n 0-9)
  • The DXCC countries of the European Union at the time of the contest: 5B, 9A, 9H, CT, CT3, CU, DL, EA, EA6, EA8, EI, ES, F, FG, FM, FR, FY, HA, I, IS, LX, LY, LZ, OE, OH, OH0, OJ0, OK, OM, OZ, PA, S5, SM, SP, SV, SV5, SV9, SV/A, TK, YL and YO.
Remark: A QSO with a Belgian station can give you 2 multipliers (UBA section and prefix). Multipliers count once on each band.

8 - Final Score

Total QSO points (from all bands) times the total number of multiplier points (from all bands).

9 - Special Conditions

The use of DX-Cluster facilities is permitted. It is recommended that you use the DX-Cluster system in a decent way. This means to point out DX stations, new multipliers and propagation in challenging bands. It is not recommended to spot your favourite ON or other stations with the purpose of generating advantages for these stations. This kind of "friendly spotting" will only result in a bad reputation for yourself and for the spotted station.
Remote stations need to combine RX and TX facilities in one station. Remote listening facilities are not allowed more than 500m away from the transmitting site

10 - Logs

Number of logs: Only 1 log per station will be accepted.
We will only accept CABRILLO logs. Rename your logfile to MYCALL.CBR or MYCALL.LOG where "MYCALL" is your call sign. (Example ON7SS.LOG).

12 - Special SWL Rules

Only stations taking part in the Contest may be logged for scoring purposes. Logs should show in columns: Time (UTC), call sign of "Station Heard", complete exchange sent by this station, call sign of station being worked and a RS(T) report on "Station Heard" at SWLs QTH. If both sides of a contest contact are heard they may be claimed as separate stations and the call signs have to appear in the "Station Heard" column. A station may only appear once per band as station heard. In the column "Station Worked" the same station may not be logged more than 10 times per band.
Please use the freeware program SWL_dqr_Log from SP7DQR. This program can be downloaded from http://sp7dqr.pl/en/contests.php.

13 - Contest certificates

Belgian winners receive a trophy if a relevant number of QSOs is made.
Certificates will be made downloadable from the UBA Website.  However, given current circumstances, participants from the Russian Federation and from Belarus will not be able to claim a contest certificate.
The European Union Trophies goes to the European Union operator in the Single Operator class (A, C or E) high power and low power depending on who scores the most points of both the CW and the SSB Contest.

14 - Penalties and Disqualification

  • QSO’s with incomplete or incorrect exchanges will count for zero points, but no additional penalty will be applied.
  • QSO's that are not in the log of the other station will count for zero points, but no additional penalty will be applied.
