[amsat-bb] looking for ARRISat-1 QSO! 1607utc pass 31Dec2011
Okay, time is running out... Heard myself on multiple passes of ARISSat-1 lately, but nobody has been around or able to make an SSB QSO. I'll be on during the 1607utc (11:07am Eastern) pass today, hoping to make a voice contact. SatPC32 is set for 145.930 receive, so I'll be close to that frequency. Hope to make contact with somebody :) 73, Mark L. Hammond [N8MH] ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

[amsat-bb] Re: ARISSat-1 (37772) decay
Hi, My prediction for the decay of ARISSat 1 still stays on the same date: January 4 +/- 1 day. As the aerodynamic drag increases, the telemetry of the satellite should show ever higher temperatures in the coming days. Especially interesting is the data from the Kursk experiment, that measures the density of the air around the satellite. Happy New Year to all! 73, Nico PA0DLO On 2011-12-22 16:15, Nico Janssen wrote: Hi, My current prediction for the decay of ARISSat 1 is January 4, 2012, +/- 3 days.

[amsat-bb] Re: ARISSat Today--low power, I would guess
And the latest as of moments ago: As ARISSat was going over NH (actually well north of NH) it appears to have switched from low power to high power. As it rose above the horizon, it was in low (the carrier cut off shortly after AOS), but then when the carrier came back on, it stayed on. Despite a fairly strong signal that sounded good, I decoded 2 Kursk frames, but no satellite data. This has happened before, and I don't know quite what gives. Someone in the general vicinity did get satellite data, since it appeared on the telemetry web page. I wonder if one cell is getting a little wonky, so if that is the one facing the sun, we don't get quite enough power. Or maybe the side that is shaded by the handles etc. Keep going, little friend! It's nice to hear your voice a couple times per day... Burns, W2BFJ ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

Ground Station Operator says that we seemed to be able to accumulate the electricity with enough many electricity to get through eclipse, or the malfunction occurred in the circuit which turned on an analog transmitter at the time of the battery terminal voltage recovery, but it may work normally now. http://blog.goo.ne.jp/fo-29/ http://www.ne.jp/asahi/hamradio/je9pel/fo29rcvr.htm JE9PEL, Mineo Wakita ___ Sent via AMSAT-BB@amsat.org.

AMSAT NEWS SERVICE ANS-001 ANS is a free, weekly, news and information service of AMSAT North America, The Radio Amateur Satellite Corporation. ANS reports on the activities of a worldwide group of Amateur Radio operators who share an active interest in designing, building, launching and communicating through analog and digital Amateur Radio satellites.

January, 1, 2012 To All RADIO AMATEURS BID: $ANS-001.01 - A Note About the New AMSAT News Service Format The ANS news bulletins have traditionally been sent out using a packet header format on each item. In the year 2012 we are no longer sure how many VHF-UHF PBBS systems remain active that are re-distributing ANS bulletins via RF-based AX.25. Perhaps the packet header is no longer a requirement for each individual news item. ANS plans to continue to distribute the bulletins in our traditional plain-ascii format so this is not changing. Previous inquiries have indicated a very strong preference for the plain-ascii format. In this bulletin you will observe we have preserved the e-mail style of plain ascii text, 70 character lines. We preserved packet compatibility by placing a single packet-header at the top of the news and a single /EX at the end of the entire news. If this still goes out by packet SB SAT @ AMSAT $ANS-001.01 should still be able to be pro- cessed, received, and read. Happy New Year from the AMSAT News Service crew! - ARISSat-1 altitude is rapidly decreasing On Tuesday, 27 Dec 2011, ARISSat-1 was losing about 4.1 km (~2.5 miles) a day in altitude, by Friday 30 Dec 2011 the decay was 5.9 km (3.6 miles) per day. This rate will continue to increase over the next days and ultimately result in the satellite burning up in the atmosphere. Telemetry reports haven't shown a large increase in temperatures yet, please collect and report these values during each illumination period. There have been a number of people that continue to update their calculations on when the satellite will re-enter. Dates range from 30 Dec to 16 Jan. The fall rate dh/dt is increasing dramatically. Be sure to do daily updates of the ARISSat-1/RadioSkaf-B Keps from Celestrak.com. The ARISSat-1 orbit changes daily while the satellite continues to lose altitude. Roland, PY4ZBZ from Brazil has updated graphs of height and fall rate on his Web site: http://www.qsl.net/py4zbz/arissat.htm#r [ANS Thanks Gould, WA4SXM, for the above information.] - Now that ARISSat-1 is in its last days, the Chicken Little Contest web site has been updated to include the individual submissions in each category nearest its likely reentry time. www.amsat.org/amsat-new/ARISSat/ARISSatContest You can see how you are doing compared to the competition! It appears that the submissions are sufficiently spread out that we will be able to determine unique winners in each category. However, you can help with this by keeping the telemetry submissions coming. Space Command does not maintain precise Tracking and Impact Prediction (TIP) for minor spacecraft. A small satellite is considered to have reentered when three consecutive tracking stations fail to acquire it, which leaves a considerable window. While the formal last telemetry contest is only open to submission through the telemetry programs, keep listening and note the time and place where you hear it last. After it has been confirmed to have reentered, the last reception including voice and CW, may help narrow that window unless transmissions cease significantly before reentry. [ANS thanks Alan, WA4SCA. For this information] -- OSCAR-11 REPORT 29 December 2011 This report covers the period from 01 September to 28 December 2011. The satellite has continued to operate in a very predictable way since the last report, and no changes have been observed. During this time the satellite has been heard reliably during its ten-day transmission periods. Excellent signals have been reported from stations located around the world, and good copy obtained from decoded telemetry frames. The easiest way to check whether OSCAR-11 is
[amsat-bb] Re: FO29 and Kenwood TH-F6A
Hi John! Glad to hear that FO29 is back-now to get on it! Has anyone tried using a Kenwood TH-F6A HT to receive FO29, since it does receive SSB? I would be hooking it to an external antenna. Is it sensitive enough on SSB to hear the satellite? The QST review shows its sensitivity is a little down on HF and 6m SSB. I also have a TH-F6A. For higher FO-29 passes, this HT is OK. Not great, but it works. You are correct about its sensitivity being down in SSB. Especially when compared to its performance in FM. An FT-817 has a more sensitive receiver for 70cm SSB than this HT. Also, you'll probably want to set the SSB tuning step at the smallest setting (33 Hz). That's not as small as other radios, but small enough to get signals lined up in the receiver. If you can transmit CW or SSB on 70cm, why not try that HT on the 2m downlinks for AO-7 (mode B) and VO-52. Just like with FO-29, you'll probably want to only look at the higher AO-7 passes when using this HT. For VO-52, I do OK when the satellite is above 7 or 8 degrees elevation when using my Elk log periodic. VO-52's stronger downlink makes it a lot easier to hear on the TH-F6A compared to AO-7 and FO-29. I have not tried the TH-F6A on AO-7 mode A. It might be a tougher challenge, in that AO-7 mode A can be tough to hear without a good antenna setup for the upper end of 10m. Good luck, and 73!

[amsat-bb] Re: FO29 and Kenwood TH-F6A
I've heard FO-29 with my F6, though kind of barely. You definitely need an external antenna (more than just an extended whip), and another radio for the uplink since the F6 is FM-only on transmit (and it's not full duplex).

[amsat-bb] ARISSat-1 SSTV cameras
Hi folks, I just received an ARISSat-1 pass that crossed into eclipse about 80% of the way by. As expected, the FM signal dropped pretty much immediately upon entering eclipse. But that's not the reason for the post... I got a really neat SSTV picture of the Sun streaming into the camera, just a few seconds before the eclipse. Unfortunately it didn't show the planet below (ran out of picture), but it got me thinking: Did the design team do anything to protect the cameras when they're looking directly into the Sun? Were these special cameras, or are we counting on the satellite spin to keep them from getting too much of a sun tan and burning a hole in the sensor? I ask because the camera I mounted on my Az / El rotor is dying, and I need to replace it. I built a mechanical shutter to cover the lens when not in use, but I wonder if it's worth keeping that mechanical contraption when I get the replacement.

[amsat-bb] ARISSat-1 transponder question
Happy New Year! This morning I kicked off the new year with 2 passes of ARISSat-1, copied both CW beacon, BPSK telemetry and FM voice/SSTV simultaneously on Kenwood TS-2000. I would also like to try the transponder but don't know if my transceiver allow it? This TS-2000 has all modes on its main transceiver but its sub receiver only supports AM or FM. Could anybody help?

[amsat-bb] Re: FO29 and Kenwood TH-F6A
Thanks to everyone for their comments on the F6A, and it is good to know that it will work, although maybe an in-shack preamp might help some. I would love a FT817 but it is a little out of the budget right now. A F6A would be nice because I want to keep an HT and it could replace the Wouxun I have now, as well as the Kenwood TM251A I am using for the FM satellites. Selling both of those could come close to the price for a used F6A. I would be hooking it to an outside antenna. I don't currently have a way to transmit on UHF, though, except with the Wouxun. I dont' have an adaptor to hook up its reverse SMA connector to the outside antenna. I do have an Icom 706 original I can use to transmit on 2m SSB/CW with, so FO29 would work if I have the F6A for receive. Maybe I could even key the F6A's PTT button to send CW on UHF to get on VO52 with it. Hope everyone has a nice 2012 and catches lots of satellite passes. See everyone tomorrow on AO27 and SO50. It will be weird having tomorrow be New Years Day but everyone celebrating it on Monday! 73s John AA5JG - Original Message - From: Patrick STODDARD (WD9EWK/VA7EWK) amsat...@wd9ewk.net To: amsat-bb@amsat.org Sent: Sunday, January 01, 2012 12:29 AM Subject: [amsat-bb] Re: FO29 and Kenwood TH-F6A Hi John!

[amsat-bb] Re: ARISSat-1 transponder question
Hi Thu, Happy New Year to you as well! I don't have a TS-2000 myself, but that rig should be fully capable of working the ARISSat-1 transponder, many hams use the rig for AO-07 and VO-52 which work essentially the same way as ARISSat. The challenges (above copying the downlinks as you're doing now) are that you'll need to have the uplink (70cm) antenna working, as well as have the computer control of doppler for up/down on your rig. SatPC32 works well for this. Also, signals through the transponder are very weak, so you'll need to have some gain in the antennas and/or power on the uplink. On a related note, I had a nice (short!) QSO with N6EV tonight through the transponder -- 01/01/2012 0124z. It's super-exciting to hear another station coming through the passband!!! ARISSat-1 may not have much time left, but it's still working great. 73 and Happy New Year all, Dave KB5WIA On Sun, Jan 1, 2012 at 4:43 AM, Vu Trong Thu th...@fpt.edu.vn wrote: Happy New Year!
