After several iterations and as a result of intensive research and discussions with all involved transponder builders, the P3-D Project Manager Dr. Karl Meinzer, DJ4ZC gave his final OK to the P3-D Transponder frequencies.
They have been carefully selected to minimize mutual interferences with other satellite projects and are also coordinated with IARU bandplans by the P3-D Frequency Coordinator, Freddy de Guchteneire, ON6UG, with the help of Peter Guelzow, DB2OS and Werner Haas DJ5KQ.
