Hi Mario, For L band uplink I use an SSB Electronics UTM 1200DLX. It generates about 15 watts out for 5 watts in. It has a 144MHz input. If I am working mode L/S, I will use my FT-817 for the mode L input, the 5 watts (about 3 to the UTM 1200 on the roof) works fine. That leaves the FT-736 for the 144 MHz IF for the S band downlink. Mode L/U would allow the use of just the FT-736, 144MHz for the UTM 1200 and then receive on the 70cm side.
