Danny - I was right where you are now a few years ago: Looking for info on what to work right away. So I created a Web site that concentrates on just that: http://www.work-sat.com I think you'll find it helpful! Clint, K6LCS 909-241-7666

Hey all, Being new to this and knowing all the Sats that are out there I was wondering which ones I should concentrate on for voice contacts? I've tried to listen to a couple so far but have had no luck. Thanks for your input on this in advance. Danny Monge AD6SJ

ARISSat-1 Voice Telemetry 03:44z 8/16/2011
by Greg D. 16 Aug '11

16 Aug '11

An annoyingly high pass this evening (79 degrees, on the wrong side of a South-centered rotor)... 03:44z 8/16/2011 MET = 60 min IHU temp = +39c Control panel temp = +29c Battery = 35.58v Charge = -20ma Satellite appeared to switch to low power mode right before this, as there were a couple of voice greetings ("Hi this is ARISSat-1") prior to the telemetry, then 2 minutes of silence. When the satellite came back after the 2 minute pause, I tried hitting the transponder with some CW dits. Nothing heard on the downlink, though my rotor was horribly mispositioned at the time (ref the afore mentioned annoyingly high pass...). Greg KO6TH

ARISSat-1 voice telemetry 05:22z 8/16/2011

Hi folks, Another pass just now... 05:22z 8/16/2011 from CM98 in Northern Calif. MET = 64 min IHU Temp = +34c Control panel temp = +28c Battery = 35.86v Current = -4ma Low power mode, I think. 2 minutes off after the telemetry, then voices and an SSTV picture, but very poor reception for the second half of the pass, in contrast to prior passes. Given that the temperatures are falling, perhaps we have a different orientation? Greg KO6TH

ARISSAT-1 CW beacon heard
by G. Beat 16 Aug '11

16 Aug '11

Quickly dialed up 2 meter SSB/CW receiver this evening Heard ARISSAT-1 CW beacon (weak) -- 15 August, 21:15 CDT. Appeared to be in Lo Pwr mode, No BPSK telemetry or FM heard. Copied part of the CW beacon (some fading) the "old fashion way" -- no computers were used or harmed with this method. IHU 53C; CP 31C; Battery 35 C missed the current and then signal disappeared. == w9gb
