Hi Zlatko,
thanks for your interest.
Transverters were made by OK1FPC - they're harmonic mixers, ~12 GHz multiplier and a good OCXO.
SP2IRR uses 2 m IF, I have 70 cm IF, TX power is 0 dBm, NF 7 dB
I'll post some pictures in a few days when I'll have some time to take phonos in good lighting conditions.
Best regards
