Hi all,
just worked AO-51 in mode L/S over EU starting at about 19.45 UTC. I can notice a very deep qsb from about S3 (converter noise) to S9+20. I can't remember a so deep qsb in the past, 1-2 years ago the sat in this mode was with very "stable" signals. Is AO-51 not well stabilized ? Any info from command stations ?
My working setup is: RTX: Icom IC-910 converter: DB6NT 2,4 Ghz to 144 Mhz, 0.43 dB NF antenna: grid 70x70 cm. oriz. pol.

I got the same results here with a BBQ grid very huge fades i switch to a simple patch element and the fades deepness has been reduced by about 70% but overall signal has been reduced too.
Will try an helix and it will be interresting to know what kind of antenna the 2.4ghers are using
