So while there has not bee any significant published progress here. Work behind the scenes is still going on. 

The 2.3/2.4GHz RX antennas have been built, the RX image filter has been measured.

This is what you get for not documenting things properly the first time! I tuned the damn things for <0.8dB loss in the pass band and forgot to mark what filter is on what freq. The things are former diplex filters from a 2.0/2.2GHz QPSK datalink. More on them later.

The RF AGC has been changed to IF AGC due to it being easier, even if the IF is outside the BGA2031 speck it should still likely work. And at low IF frequencies I can use dualgate mosfets which I have. 

The exact IF frequency and IF bandwidth are still open. I'd much prefer to use something like 200kHz wide, but all the commonly available filters for that bw are 10.7MHz ceramic units. Using a 10.7MHz IF would add even more stages to the system and increase it in complexity. So it is still possible that I'll just use a 608MHz SAW filter fro ma satellite TV receiver. But having the thing +5MHz wide puts additional strain on designing a very linear PA and running it far away from saturation. Neither of which are fun at 10GHz. 

More talk later.
