SO thinking ahead to the IC 9700. What satellite activities are happening on 1.2 ?
Any homebrew antennas on the horizon? Does 1.2 require mast mounted preamps?

You will not need a mast-mounted pre-amp because 1.2 GHz can legally be used only as a satellite UPlink. There is nothing to receive there.
AO-92 and ESEO have 1.2 GHz uplinks, for sure. There may be others, as well -- I'm not up to speed on that right now. -- Mark D.

Hi Jim,
In the amateur satellite service, 1.2 GHz is uplink only. So you don't have to worry about preamps for receiving satellites, but if you do terrestrial L band you can consider that separately.
I can only speak for what I know for sure which is AO-92 (and AO-95, but she is currently on leave). On days selected by AMSAT Ops (usually Sunday UTC) AO-92 is in mode L/v which is 1267.350 MHz up and 145.880 Mhz down. 145.880 is the same downlink as in its normal mode U/v.
