With the CQ WPX RTTY Contest this weekend and the WPX SSB Contest coming up in March, there's news of special prefixes being approved in two different countries to mark significant anniversaries. The ARRL Letter reports that in celebration of Peru's bicentennial as a republic, the Peruvian Radio Club will be operating OC200P, OC200E, OC200R, and OC200U at various times throughout 2021. The calls will alternate in different months.
Two hemispheres away, the Finnish Amateur Radio League is celebrating its centennial and will be operating OH100SRAL throughout the year. In addition, several well-known Finnish hams operated OH0W from the Aland Islands from January 29 to February 3 for the CW weekend of the CQ World Wide 160-Meter Contest.
