[amsat-bb] AO-40: First uplink trial disappointing.....

[Kc2hax@xxxxxxx]

Hi Robert,
My uplink set is similar to yours, a single 13dBi 11 elYagi (Cushcraft 
A44911S in vertical pol) and 50 Watts (FT-847). With this set (very modest) I 
was able to uplink from MA 211 this morning with very good donwlink signals  
S up to 9 and R5, excellent for SSB (D/Link antenna today was a 28 turn 
helix) . If I remember well I think you were not on the footprint at this 
time, before that -when Germany was clearly in the footprint- I tried and was 
not able to copy my downlink. I don't know exactly why but I spent a lot of 
time (nervous and excited) to find my D/link signal. I was hearing very well 
the NA stations my copy was no so good from the EU stations. At the time I 
had to leave 12:30 UTC, the signals were really strong (S9).
So, do not despair wait for a better conditions you are gonna enjoy it!!!
