OK1KIR EME Team - 1296 MHz, Our New System

The picture gallery shows our new system for 1296 MHz. The first QSO was with C31TLT on August 25^th 2005. We made 805 CW, SSB and JT65 QSOs until now (August 2011). The system is continuously improved, the first QSOs were made with septum polarizer. Later we added 3 ring-chokes and rotatable dual dipole (EIA) feed for linear polarization. Also LNA were changed, currently we are using 0.3dB VLNA (G4DDK design / MGF 4919G). The last stage changed from GI7B tube to 400 W rf from modified Siemens SSBA and final TH308 tube PA in 2007. New SSPA with more than 1kW RF is used from fall 2010.
