[Moon-net] 3.4 GHz Activity weekend report

[Charlie Kahwagi]

Hello all,
                great to be on 3.4 GHz on the weekend.
It's a pity quite a few stations don't have a window to me here in VK!
Nonetheless I had very good results with the new feed.
The new feed is a scaled version of "RA3AQ's stepped septum optimised for f/d 0.39-0.4 GHz "  orginally  for 1296.
Compared with the previous "screw polariser"  I am getting much better dish efficiency,  circularity and the RL  and Isolation figures are excellent.  Consequently I have gone from echoes barely perceptible to  echoes  very loud:  > 10dB above the noise (according to spectran)
I will be staying with this feed and I will now build a scaled version for 2.3 as I look to get on this band very soon.  in time I will try versions for 5.7 GHz and compare it with my  Screw polariser ( which already works well on this band)
If all works OK then I will try it on 10 Ghz.

My reports on 3.4 GHz  showed a VAST improvement over last activity weekend,  although moon condx  were the same ( if not slightly worse).

Wkd.........  G3LTF  529/549  , OK1KIR #5   O/O ,    LX1DB 559 /559  and SSB ,  
I tried with N9JIM.......Nil heard  ( problems for them on 3400)
Tried WW2R........partial copy my way,  Dave reports hearing me well.

I will keep the 3.4 GHz feed in place for a while,  so if anyone wants to try with me then please let me know.

AND....If  anyone can sort out a window to VK  from those that presently cannot,   feel free to do so ...Hi Hi
