[amsat-bb] Re: FW: Wanted: ARISSat-1 BPSK1000 recordings
Hi Alan, Thank you for sharing your experiences. Perhaps your observation c can be explained by the version of Excel you are using. I'm using MS Office 2010 and it sees all of the columns fine. An earlier report from a tester suggest that some older versions of Excel cannot handle all of the columns produced by the telemetry and the program. c When running the test file Excel complains that data has been lost from the CSV file because the number of columns exceeded the 256 column limit. (Excel opens OK and all 256 columns contain data) I suspect a newer version of Excel is required; maybe OpenOffice can handle it? 73, Mark N8MH At 04:35 AM 2/13/2011 +, you wrote: Hi Douglas, I have some recordings but I am not sure they will be of much use. However I thought it might be useful to share my experiences with the telemetry. I monitored the audio downlink on the first two passes and the data downlink on three passes. I used the ARISSATtlm-0.47 software for decoding on the data passes. On the first pass I could not clearly see the CW signal on the tuning indicator so no decode of the CW or data. The next two pass I had good CW decode and could line up the CW signal OK but no decode. After the passes (naturally) I re-read the article in the AMSAT journal and realized the importance of the 48k, 16 bit sample rate. The article claims that the ARISSATtlm configures the sound card to these values but when I checked the sound card was still at my normal 44.1k sample rate. Perhaps the software sets it to 48k and then sets it back to its previous value but I suspect not. I re-sampled my recording at 48k but still no decode. I noticed also that the CW decode from the recording was not as good as the original so perhaps the recording was at fault. To test this re-sampling method I re-sampled the test wave file at 44.1k and confirmed that it would not decode. I then re-sampled this file at 48k and once again it would decode. (i.e. the re-sampling worked OK.) This again perhaps pointed to a problem with the quality of my recording. Some observations. a Make sure the sound card output is set to 48k/16bit. b I noticed that the live telemetry sounded quite different from the test wave file. The data signal was much more obvious. c When running the test file Excel complains that data has been lost from the CSV file because the number of columns exceeded the 256 column limit.

[amsat-bb] Re: ARISSat-1 test
There was a posting that alluded activation on April 12 but I find nothing on the Russian site about ARISSat-1. I suppose they could connect it to the test antenna on the ISS like they just did. A lot of questions about the battery condition waiting for a launch in July. I would suppose there was a external power jack provided for testing. Could that power ARRISSat-1 from the ISS power systems for recharging/test transmissions? This is a question and not based on any knowledge I have about what it has. July launch gives me time to restore my tracking antenna systems after being damaged by wind in Dec. I will probably get the antennas remounted sooner, but I still have to T/S and repair the B5400 controller. 73, Ed - KL7UW At 05:38 AM 2/13/2011, g0...@aol.com wrote: I wonder if it will sit until July?

I'd like to express my thanks to all the ARISSat team volunteers who've been working so hard recently to get the telemetry decoding software, Website/twitter and other activites all ready for Feb 16. The deployment of ARISSat-1 was originally planned for the end of Feb and was then brought forward by 2 weeks so the volunteers must have been working flat out to get everything ready.

In addition, the cosmonauts switched on small satellite Kedr to be activated on April 12, so RF-amateur station all over the world could hear the signals from space. Kedr was developed under the RadioSkaf experiment. The satellite's name was adopted by Yu.A. Gagarin call sign in his historical flight, namely Kedr. The satellite's signal will be transmitted at radio amateur frequency of 145.95 MHz. Kedr has radio amateur call sign RS1S.

ARISSat in it's flight configuration does not have a provision for external power. During ground testing we have a special cable for external power that connects where the battery goes but that cable was not planned to be used on the ISS. There is the capability to remove the battery and recharge it while onboard the ISS. That should happen only once.

Activity is to celebrate/ publicize the first ARISS (International Space Station) contact with one of the Institute for Technological Development and Innovation in Communi- cations (IDeTIC) facilities on campus. The special event station will be on the HF bands, 40-10 meters, using CW, SSB, RTTY,*PSK31* and SSTV. Also, activities are planned for VHF (2m FM local and R7 repeater) and the satellites (AO-27, SO-50, AO-51 and VO-52). There is a special QSL card designed for this event that will be automatically mailed to your QRZ.com address. Please, keep in mind that they aren't highly skilled radio operators, so be patient if there are any pileups. More info is available on the QRZ.com under EG8ISS.
