Hi Dave, G1OCN

The polarphaser for 2 meters was also described many years ago in OSCAR-NEWS
of AMSAT-UK but unfortunately I don't remember exacly the numbar of the
above issue.

In my opinion it is not easy to use a polarphaser because it requires two
coax lines coming down from the crossed yagi.

In addition using the actual LEO satellites the rate of change of
polarization is very fast during one pass and while operating you have not
the time and one more hand to rotate the dial on the front of polarphaser
to get the strongest signal.

By the way it was very nice to use the polarphaser in 2 meters downlink with
HEO satellites OSCAR-10 and OSCAR-13 because as they were stabilized the
rate of change of polarization was very very slow.

I suggest you to save your polarphaser for P3-D
