Does anyone know if Professor Harris was involved in the design of any aspect of ARISSat-1? A weird inquiry from my In Box this morning ... Clint Bradford

ARISSSat-1 Help
by Bill Photinos 06 Aug '11

06 Aug '11

Tried to work the 1201Z 06AUG2011 pass of ARRISSat-1 from FM26 this morning without much luck. I have been successfully working the FM birds for a while but this is my first attempt with a linear bird. I was wandering if someone with a similar setup could verify my settings? Equipment as follows: Icom IC-910H Gulf Alpha 2M/70cm dual band yagi. 2M->6 element 70cm->8 element antenna LVB tracker box connected to a Yaesu G-5500 Az/El Rotator controlled by Ham Radio Deluxe. In HRD I set the following: Rx - Center of 145.930 USB Tx - Center of 435.750 LSB I set it to control doppler on *both* freqs. I am pulling the keps from Celestrak now. This morning's pass was to North->South and to the West of my location(FM26au). I noticed that the Rx was always being set lower than the center freq, and the Tx was lower before max elev and higher after Max elev. I had about a 9min window. About a 1/3 of the way into the pass I thought I heard some garbled voice. In the last 1/4 of the pass I definitely was hearing some CW. I can post the recorded .wav file if necessary. Would greatly appreciate any help. 73, Bill - W4RVN

ARISSat-1 BPSK Telemetry decoded
by Jason Charles 06 Aug '11

06 Aug '11

I finally successfully decoded the BPSK telemetry!! On a 15 degree Max El pass at that! I wrote up a post that will hopefully help others if they decide to try it. The audio is also available in the post so you can hear what it sounded like during the pass. http://www.n4jtc.com/?p=85 This is a lot of fun! 73 Jason N4JTC

Hi Patrick, It wasn't the 1509 pass that I may have heard you on, but the 1332 one. I was on the 1509 pass, but couldn't hear my downlink then. 73 Ray

RADIOSCAF-B Lemonade
by Rich Dailey 06 Aug '11

06 Aug '11

I made RADIOSCAF-B lemonade this morning at approx 8:50 UTC: Ingredients: One (1) RADIOSCAF-B satellite w/missing(?) receive antenna Twenty-five (25) watts of rf (CW) to 11 elements 11 elements for receive My downlink was not super strong, but certainly Q5. This was a maximum 6 degree elevation pass for me. Six degrees. This, and reading Bruce's description of WB4SON's success with QRP leads me to ask, are we SURE there's not a 70cm antenna attached? Antenna or no, RADIOSCAF-B or whatever you wish to name it, I think this is a raging success of the platform. Congratulations to all involved. N8UX.

KP4WES voice as heard on Arissat-1
by (KP4TR)Ramon Gonzalez 06 Aug '11

06 Aug '11

Hello, Last night I was caught by surprise while listening to Arissat-1 over Puerto Rico the voice of a boy called Wesley (KP4WES). It was in Spanish, and now I found out he's the son of WP4T (Walter) who I know personally and have worked him on AO51. KP4WES is only 9 years old! Here's a video of what I captured last night while Arissat-1 was over Puerto Rico: http://www.youtube.com/watch?v=NKaAMw3yJz0
