Hi Jerry,

I was seeing very good conditions yesterday when I copied the ALON/ALAT 
telemetry numbers. Today at 1555 UTC, conditions are so so. 22 degree squint 
and range of 61,600 km right now. CW qso's, piece of cake. SSB rough but can 
be done. Telemetry is copyable, but blocks are getting corrupted due to spin.

FYI, I'm taking down the Meyers grill dish here. G3RUH patch and solid dish 
going up. I expect 3 things to happen:
1.) Increase signal due to circular polarization
2.) Decreased noise due to less over illumination/better dish-feed match.
3.) Slight performance gain due to DB6NT preamp being mounted directly at the 
feed eliminating 3' RG-8 jumper on Meyers Dish.

I'll let you know how it comes out and send you a picture.
