The Prefix Hunter PSK Award was devised by the European PSK Club on 14th January 2007. This was to sponsor a series of PSK awards based on the radioamateur callsign prefixes. Prefix Hunter 100, Prefix Hunter 200, Prefix Hunter 300, Prefix Hunter 400, Prefix Hunter 500, Prefix Hunter 600, Prefix Hunter 700, Prefix Hunter 800, Prefix Hunter 900 and Prefix Hunter 1000 Awards may be claimed by any licensed radio amateur, club station or SWL eligible under the EPC Awards General Rules who can produce evidence of having contacted 100, 200, 300, 400, 500, 600, 700, 800, 900 and 1000 different prefixes respectively at the time of application by using any PSK mode. EPC membership is required for the Prefix Hunter PSK Award applicants. All contacts must be made since January 1, 2000.
Credit will be given for contacts made on any of the amateur bands below 30 MHz. Confirmations from the EPC Short Wave Listeners 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. Exception: Permanently docked exhibition ships, such as the Queen Mary and other historic ships will be considered land based.
Prefixes: The letter/numeral combinations which form the first part of the amateur callsign will be considered the prefix. Examples: G6, M3, WD5,HG3, HG19, WB2, KC2, OE2, U3, ZS66, etc. Any difference in the numbering, lettering, or order of same shall constitute a separate prefix. A prefix will be considered if licensed by the governing authority in the country of operation. In cases of portable operation in another country or call area, the portable designator would then become the prefix. Example: WN5N/7 would count as W7, J6/WN5N would count as J6, KH6/WN5N would count as KH6, etc. Portable designators without numbers will be assigned a zero (0) at the end of the designator to form the prefix. Example: LX/WN5N would count as LX0. When claiming a prefix which has been sent as KC5KKY/XV5, for example, it is requested that the claimed prefix be listed in the proper alphabetical position, such as XV5/KC5KKY. The portable prefix must be an authorized prefix of the country/area of operation. Maritime mobile, mobile, /A, /E, /J, /P, or interim license class identifiers do not count as prefixes. All calls without numbers will be assigned a zero (0) plus the first two letters to form a prefix. Examples: XEFTJW would count as XE0, RAEM would count as RA0, AIR as AI0, etc.
