Re: ID of hardware in the SSTV

Larry and Mike: Thanks for the info. I had forgotten about the call sign color indicating the camera. My "my mystery object" is always in the GREEN (+Z) view, so it is clearly on the spacecraft, and as Mike says, I suppose that is likely the 2M antenna. The shape is what confused me...it appears to be flat with a kink on the end, which is not what it looks like from pre-launch pictures. But this is a different angle too. The other thing that led me astray was that some other photos had a straight line in them which I took to be the 2M. See for example http://www.amsat.org/amsat/ariss/SSTV/uploads/3376.jpg. However, now that I remember the color key, I can see that it does not appear in every view from the same camera, and in fact there are similar artifacts even in a few +Z views. So it must be something external; maybe some artifact due to glare (it always seems bright). Anyway, thanks. This is really cool stuff!

ARISSat-1 10 Aug 2340 UTC over West Malaysia
by Sion Chow Q. C. (9W2QC) 11 Aug '11

Dear All, Not sure if this was low power or high power, but the TX seems to be on continuously, so I believe the satellite was in high power mode. The following was copied from the voice telemetry on 145.950 MHz +/- FM 11 Aug at 0740 MYT or 10 Aug at 2340 UTC, ARISSat-1 Telemetry: MET - 10387min IHU Temp - 38C Control Panel Temp - 47C Battery Voltage - 33.03v Battery Current - +325mA (charging) MET - 10390min IHU Temp - 38C Control Panel Temp - 48C Battery Voltage - 33.36v Battery Current - +325ma MET - 10392min IHU Temp - 38C Control Panel Temp - 48C Battery Voltage - 33.43v Battery Current - +379ma 73, Sion, 9M2CQC

Burns: I viewed the ARISSAT SSTV gallery website (http://www.amsat.org/amsat/ariss/SSTV/) and viewed images that had a green callsign which were taken from the +Z pointing camera. Several images show the partial end of the Kapton film 2M 1/4 wave omni directional collar antenna. Mike Schaffer KA3JAW

ARISSat TLM decoding using FCD
by PA3GUO 11 Aug '11

11 Aug '11

Just sharing the results of my recordings of last night: (using the FCD + HDSDR) - FM voice works fine - Xponder works fine (HB9AOB was very clear) - CW decoding works fine (the Tuning indicator locks on the CW bump) - BPSK decoding did not work (I hear & see the signal, but no decode) Is the BPSK decoding very sensitive to doppler / freq hops ?

CM79 - Another chance Saturday August 13th with SCRA/N6T
by David Palmer KB5WIA 11 Aug '11

11 Aug '11

Hi Everyone, In case you missed me at CM79 this last weekend, the Sonoma County Radio Amateurs are going to be there this coming weekend August 12-14th. Charlie KZ6T reports that they'll be active on HF, 2m, 6m, but also will try for a few satelllite passes on Saturday August 13th signing as call N6T. This is the list from Charlie, all times local: AO-27 11:54(L) 65 degree pass AO-27 1336(L) 14 degree pass SO-50 15:42 (L) 57 degree pass AO-51 16:51 (L) 10 degree pass AO-51 18:25 (L) 75 degree pass (occurs after break down time) http://scranews.wordpress.com/2011/06/09/scra-sponsoring-mini-dxpedition-to… I certainly wish them luck!!!! Maybe I'll get to put CM79 in my own logs this time! 73 de Dave KB5WIA
