Lots of activity as usual. I noted a slightly stronger signal on the downlink on Left Hand Polarization.

May be a note of interest. First chance I had to try and work the new bird and noticed that I had similar problems to the drop outs as previously mentioned. However, in my case I discovered at the end of the pass that I had forgotten to turn on the tone! I wonder how many may still may not have their tone enabled or wrong tone frequency?
I also noticed that the bird was quite strong on the arrangement I was using and did not bother to turn on the receive preamp. I was using my IC-910 running one watt for the up link on a Ringo Ranger II vertical and my down link antenna was a two meter simple ground plane which seems to work well on the satellite frequencies. It is obviously three time larger in wave length for 70cm and narrow (only has good swr on the satellite frequencies) but does surprisingly well.
I also wonder is some of the the drop outs might be due to the tones over deviating on signals and not known since they are not heard. Suggested narrow FM would probably reduce that particular problem.
Way to go Amsat-SA looking forward to more "on" time and sounds very good.

On my last 8 degrees morning pass i was able to sustain about 4 differents QSO in a row (back to back) It is not an issue on the transponder probably a new way to avoid pile up? I will have to make further test but the twist is related to over deviation and trailing tail handling if it's confirm the twist is nasty... and can be only defeated by strict rules of engagement that i strongly doubt it can be achieved anytime soon on a one channel fm satellite.
Signal reach S9 plus 30 here at 8 degrees and i missed an overhead 83 degrees pass prior to this one :( With ISS it's probably the strongest signal received here.
It will be nice folk's from Sumbandalia to explain exactly how the TR switching is working. In the mean time congratulations for this very powerful sat.
