[amsat-bb] Re: 23Cm Up converter

[N0JY]

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.

73,
Jerry
