On the ARISSat-1 pass just ended here (23 degrees max elevation), results were about the same as yesterday. I heard my CW downlink for about a minute, peaking 559. Several other CW signals were in there, but I couldn't get their calls due to the deep fades. Bruce appears to be right that

During the ARISSSat-1 pass that just went by (81 degrees max elevation), I tried the linear transponder. My CW signal peaked at RST 449. No other identifiable signals were heard, except for the CW and FM beacons, both of which were over S9. My 435 MHz EIRP was approximately 50 watts. 7

[amsat-bb] transponder at 4:00Z
