The Odessa Sister Cities PSK Award Series (OSCA) was devised by the Odessa Section (Ukraine) of the European PSK Club (EPC) on 6^th April 2009. This was to sponsor a series of PSK awards for contacts with amateur radio stations from various Odessa Sister Cities (Twin Towns) throughout the World including Odessa City itself. Sister cities, also known as town twinning, is an agreement between towns, cities and even counties in geographically and politically distinct areas to promote cultural and commercial ties. Odessa City and its 26 sister cities are listed below under their official English names.

OSCA 15, OSCA 20, and OSCA 25 awards may be claimed by any EPC member (either licensed radio amateur, club station, or DMS/SWL) eligible under these Rules who can produce evidence in a form of ADIF log of having contacted or monitored amateur radio stations from 15, 20, and 25 cities (listed above) respectively at the time of application on B(Q)PSK31, B(Q)PSK63, and B(Q)PSK125 modes. Credit will be given for contacts made on any of the amateur bands below 30 MHz. Each city counts only once. Contacts are valid on or after 10th June 2006.

QSL-cards are not required. Awards are issued to the person or club. The person or club can use any legal call sign. Contacts made from club stations or special event stations count to the credit of both the club and the operator. All stations must be operated in accordance with their licensing conditions. Contacts may be made from any location in the same DXCC country. Unless specifically stated otherwise, confirmations from the DMS (SWL) stations are accepted as confirmed contacts. All stations contacted must be «Land Stations». Contacts with ships and boats, anchored or underway, and airborne aircraft, cannot be counted. For the purposes of this award, remote control operating points must also be land based.

Please make sure that the «QTH» field in your ADIF log contains the contacted station's city. It must be a clear English name of the city as listed in the table above without any abbreviations or additions. This is a mandatory requirement to make able the manager's software to check your application correctly. The award manager reserves the right to spot call sign for inspection of applied contacts. The purpose of this is not to call into question the integrity of any individual, but rather to ensure the overall integrity of the EPC award program. More difficult attained specialty awards are more likely to be so called. Failure of the applicant to respond to such spot check will result in non-issuance of the EPC award. The decision of the award manager on this and other matters of dispute will be finals. The submission for credit of any altered or forged log extractions or, equally, bad behaviour on or off the air which is judged by the European PSK Club to bring a particular programme into disrepute may result in disqualification of the applicant from the award program.

All claims for the OSCA awards should be made using our UltimateEPC Award Management Software written by DK5UR. The award applicant should re-submit his application when claiming for higher classes of awards. The award manager will keep all your records in our database. Please make sure before you submit your ADIF log that you have checked it with the appropriate software.

All awards are issued free of charge in a high quality PDF format, and sent via email to the applicants. Awards can be printed with the highest quality and with optimal performance by applicants themselves. The Odessa Sister Cities PSK Award Series (OSCA) is issued to the EPC members only. If you have any questions, please do not hesitate to contact the award manager.
