[amsat-bb] WE WISH frequency
Hi All, Here in the UK, I had a reasonable pass (43 deg elevation) at 23:08UTC on 4th October. I did not hear 'WE WISH' at the expected frequency of 437.505kHz +/- doppler. However, I did detect a satellite transmitting on 437.515kHz +/- doppler. This satellites doppler curve accurately followed the ISS, (but was 15s ahead of the ISS). The signal was very weak, but I think I heard some SSTV in the modulation. The exact same happened 1 orbit later at 0:45UTC on 5th October (although this time about 18s ahead of the ISS). Is this 'WE WISH'. If so, is it transmitting 10kHz high ? 73s, Simon (G7WIQ) ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

[amsat-bb] Re: PROITERES
Hi All, I too was listening for PROITERES, and made a recording today (Sep 10th 11:15UTC) using my FunCube Dongle. Looking at the spectrum display, I could see the distinctive pattern of two satellites transmitting. It turns out that the orbit of SEEDS II (CO-66) was almost in perfect alignment with PROITERES, and was also transmitting its morse code beacon on 437.485MHz. I heard 'JQ1YGU SEEDS G4 3475BFB0 D83 FFE CCA 189 8ED 35F' etc. from SEEDS. See http://cubesat.aero.cst.nihon-u.ac.jp/english/seeds_2_e.html It is possible that some people listening for PROITERES today have actually mistakenly heard SEEDS II, as I found it a few dB stronger at times. The two satellites will drift apart over the next 2 days. 73's Simon G7WIQ ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

[amsat-bb] Re: MaSat-1
I was looking this morning as well, but couldn't find them. Analyzing the doppler shift indicated the pass was 50s later than the pre-launch TLE's indicated (for the 8:30 UTC pass over the UK) I updated the pre-launch TLE (by adding 50s to the Epoch time, and re-calculating the checksum) and the doppler correction on the following pass was much better. I guess the orbit may be slightly higher than predicted, resulting in a fractionally longer orbital period. 73s, Simon. G7WIQ - Original Message - From: Mark L.

[amsat-bb] Re: VEGA Keps!! (?)
Hi Mark, Masat-1 is certainly not 2012-006A or 2012-006B. They are too far forward or behind this mornings observed path. Also 2012-006C is 14s ahead of my measurement. My vote goes to 2012-0006G for Masat-1 (although there is only 8s between D, E, F, G, H J at the moment). Time will tell once the group spreads out a bit. 73s Simon, G7WIQ - Original Message - From: Mark L.

[amsat-bb] Re: Fully automated mode now.
Hi Andreas, I have also setup my station for unattended receive of Masat-1. I've gone with 2012-006G which closely matched my observed doppler shift this morning. I notice that the Budapest University website for Masat-1 has a map of all registered amateurs, including an indication of how many packets received by each person. http://cubesat.bme.hu/en/foldi-allomas/radioamatoroknek/ Do you know how they correlate received data with which amateur received it ? Everyone shows 0 packets at the moment. 73s, Simon G7WIQ - Original Message - From: Andy Kellner haw...@yahoo.com To: amsat-bb@amsat.org Sent: Tuesday, February 14, 2012 2:17 PM Subject: [amsat-bb] Fully automated mode now.

[amsat-bb] Re: Chibis-M?
Hi, I still receive Chibis-M (RS-39) on 435.315 in the late evenings. However, it isn't downlinking in morse code anymore. It sounds like it is downlinking data in a BPSK format, which I've not tried decoding. Another point to note is that it doesn't start downlinking until a long time into its pass. Presumably it is saving its battery power until its footprint is over Russia. Downlinking is also not continuous. One thing to be careful about is not to mistakenly receive Yubileiny (RS-30) which is also using the same morse code telemetry format on 435.315, and can sometimes be above the horizon at the same time as Chibis-M. 73's, Simon, G7WIQ - Original Message - From: normn3...@stny.rr.com To: Amsat amsat-bb@amsat.org; John Heath g7...@btinternet.com Sent: Sunday, February 05, 2012 3:17 PM Subject: [amsat-bb] Re: Chibis-M?

[amsat-bb] ARISSat in sunlight
Using Orbitron 3.71 software, I can tell that the penumbral duration today was 9 seconds. However, this will vary in the future as the angle of the orbit to the sun changes. However, the first sunlight the satellite will get will be very red (due to the blue light scatter caused by the atmosphere). I have observed that ARISSat-1 doesn't start transmitting for a further 14 minutes. To be more precise, I am seeing the Mission Elapsed Time (MET) counter start counting from zero about 40 seconds after coming out of eclipse, and the first BPSK telemetry frame has a MET=808. The first KURSK experiment data isn't transmitted until MET=945. However, since 12th September the KURSK experiment appears to have failed and is only sending null data. 73s, Simon G7WIQ ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author.
