It has been a while since we have had usable ARRISat-1 passes over the US. We are now starting to get daylight passes in the early evening so it's time to start having some fun with this bird again.
Last evening around 2203UTC, ARRISat-1 had a great pass over the south and eastern US. After listening to the voice and copying a SSTV picture, I switched to the linear transponder. My downlink was stronger than I have ever heard before and it stayed in there for the rest of the pass. Unfortunately there was no one to work. It's amazing that this bird can hear anything on UHF with virtually no antenna.
If you haven't worked much ssb or cw on ARRISat-1, now is the time to start trying again. We won't have this opportunity forever.

John,
Good to know. Did you notice many dropouts? I know the spin rate was dropping, but haven't seen any hard figures in several weeks.
73s,

Consider the antenna a 10 dB attenuator, not a "no antenna". View that way, you are just more likely to be using more EIRP than was intended for the spacecraft to overcome it. Thank goodness for the "capture cone" on the bottom of the antenna which protected your "favorite 10 dB pad"!
