Then your system must be quite hot!  I've read numerous posts about how
there's a significant null (60 dB or so??) around 45 degrees in the S2
antenna.  A number of people have mentioned they can't copy it at that
point.  

Isn't the G3RUH dish just 60 cm?  That's about 2 feet, so you are doing very
good if you are copying the beacon at squints around 45 degrees.  I know the
DB6NT stuff is very good.

That's great!
