[Moon-net] 10GHz EME

[Edward R. Cole]

My efforts to 10-GHz have slipped over the years, but we just successfully
moved the 2.4m ku-band dish to the new QTH.  It is currently set up with a
cylindrical feed with two wr90 w/g runs (I suspect this was to provide
orthoganal linear pols to the original VSAT system).  I propose to use one
of these for intial testing and suppose this will result in linear pol.
The dish is rotatable +/- 45 degrees in polarity.  I wonder if the roughly
2m of w/g will degrade performance?

My plan is to mount a 4-port w/g switch at the back side of the dish and
attach my 102-EME db6nt preamp on one port.  A wr90 coax transition will be
used to connect the 50w TWT which uses sma for output.

I have some of these ideas on my 10-GHz EME webpage if anyone would look
and comment on my plans.  I figure that it will be another couple years in
building as 1296-EME is the goal for next summer.

I follow the cp/linear pol discussion with interest.  CP can be done after
the system is QRV with little problem.
