[amsat-bb] OX Dxpedition Update
I just wanted to give everyone an update on an upcoming QTH change. Although I am scheduled to be in Thule until April 23rd, there is a chance I could leave as early as April 21st. I will be going to Wallops Island, VA to put our radar equipment on a P-3 aircraft and do flight tests. I will be returning to Greenland on May 1st (although there is talk that it will be pushed back to May 4). I will be in Sondrestrom, grid GP47pa, for two weeks before returning to Thule for two more weeks around May 18. Thanks to everyone that has tried to work me. You've made this trip a lot of fun! 73, Reid, OX/N0RC ___ Sent via amsat...@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

[amsat-bb] Re: Space Debris:
hi steve, thanks for an informative post. good to see the bb doing what it does best. 73 john g7hia From: Stephen Melachrinos melac...@verizon.net To: amsat-bb@amsat.org Sent: Wednesday, 14 April, 2010 0:22:34 Subject: [amsat-bb] Re: Space Debris: Greg - I didn't see anyone else reply, so I'll try. No, it's not coincidence. After the Iridium collision last year, the US Air Force decided it was in everyone's best interest for them to run conjunction analyses against many more space objects than they had previously analyzed, and report their predictions to system owners. Previously, their concern was primarily the US government's spacecraft, so we (in the amateur community) and many commercial operators never knew what was happening to our birds unless we did (or paid for) the work ourselves. But the collision (as well as the Chinese ASAT demonstration) showed that the resulting debris fields were a major hazard to everyone, themselves included. So they must have allocated more resources to the problem, as this is a massive undertaking. (Note that some reports say that the US has about 20,000 objects that are tracked and cataloged. In theory, this means propagating the ephemeris of all of these for some number of days and comparing all possible combinations across the ti! me period of the analysis.) Unfortunately, many (if not most) of the objects no longer have maneuvering capability. If a vehicle can maneuver, these warnings give them time to try and increase the separation prior to the predicted close approach. (You might have heard of some times when a space shuttle does one of these maneuvers.) But if you can't maneuver (as is the case with AO-51), all we can do is watch and wait.

It seems like we're heading into a situation like nuclear fission, where you get enough stuff interacting, and it sets up a chain reaction of collisions. Greg KO6TH ___ Sent via amsat...@amsat.org.

[amsat-bb] NH6VB back on the satellites from Hawaii
Hi! On Saturday (10 April) morning, there was an HO-68 SSB/CW pass that went from the north toward the Pacific Ocean. I was out at my normal Phoenix QTH (DM33xp/DM43ap boundary), and worked 3 stations. Early in the pass, John VE8EV called me from CP38. I've worked John in the past when I was on a road trip, and this was the first time I have heard him - or worked him - from my home QTH. After that, Mike KC9ELU in Indiana called me. Then I went back to CQing, until the third station I heard on that pass called me - Peter NH6VB. I remembered seeing his posts to the -BB last month about getting a new satellite radio, and then trying to get SatPC32 working again. We ended up chatting for a few minutes, as the satellite was approaching LOS for me. It was fun to work VE8EV and KC9ELU, but hearing NH6VB calling me on HO-68 in SSB was a huge - and pleasant - surprise. After the pass, Peter sent me an e-mail explaining his setup. His larger Yagis are still on the ground, but he was using an Arrow Yagi until those other antennas are back on his tower. For those that missed AA5UK/KH6 recently, and have not heard the only resident station working the SSB satellites from Hawaii in recent years (WH6BIE), we may now have another option for those looking to work Hawaii via satellite in modes other than FM. Hopefully Peter will show up on more passes, as he continues to get his satellite station back on the air. And, maybe, we can return this list to its regularly-scheduled subject matter... :-) 73!

[amsat-bb] AO-7 is not OK
Some days we are seeing very strange behavior in the AO-7. In some orbits can only hear the feedback on the downlink when the satellite is approaching my station at about 30 degrees elevation, before is impossible to hear any signal via AO-7. Using two pre-amplifier, one in the TS 2000x and the other with 0.6 noise with 20 dB gain. During the orbits we transmiting power with of 30 watts. The satellite does not respond. Tried with 15 watts It was then that we hear at certain points on the downlink audio too low. Its best performance is when the satellite is almost 90 degrees from my station. Yet it seems that the satellite is asking for help. This seems the batteries are not getting enough loads. Or maybe it's excessive use of power by the users of the satellite. Maybe it's time for the users of AO-7 rethink the best ways to keep QSO through it, such as the use of LOW POWER so that over time the satellite is stabilized. Long live the AO-7 73' Piraja, PS8RF The Amateur Radio is supportive and helpful in any circumstance. _ Você sabia que seu navegador te ajuda a ficar longe de vírus?

Hi Piraja, Yes, I made similar observations. If the CW is active on 70cm you can hear sometimes a very strong deviation in frequency. The CW beacon partly not decodable. I agree with you it could be an effect by low batteries or due heavy usage.

[amsat-bb] Re: Email etiquette - was Re: Re: Moon
The last time I set up a mailing list, the list manager was insistent that I did not want to set the reply-to address to the list address, noting that doing that removed any reply-to field that the sender put in there, which was a loss of important data for those users who put data in that header field. It also pointed out that it made private messages harder to do, and gave it a nonzero probability that you would respond to the group when you intended to respond to the individual. The configuration pages linked to a newsgroup post somewhere of someone ranting about the practice and proving that it was the wrong thing to do. Nevertheless, I selected that option and I will do it again. Because unless you choose that option, the most efficient way for me to reply to the group is to do a reply all. (Well, it was. This new version of Thunderbird has a reply to group option. Woot!) At that point, I have to trim the recipient list in order to send it only to the group, which is almost always what I'm trying to do. It's a pain, so most of the time I don't bother. Since most responses to list messages are intended for the list and not to the individual who wrote the message you're responding to, not abusing reply-to in that fashion deoptimizes the typical case in order to be technically correct. That is, in my opinion, a dumb thing to do in order to preserve the information in the rarely-used reply-to field. I mention this because this list is set up in the technically correct way, and I have several times sent messages to individuals when I intended them to go to the list. That is MY particular annoyance. On 04/14/2010 07:54 AM, Nigel Gunn G8IFF/W8IFF wrote: Only 4 lines of sig. The 2 dashes are the delimiter put in by the e-mail client. Could be worse.

AO-7 is definitely having problems. On the last pass at 00:00 4/15/2010, I worked a few stations. The bird was very busy, lots of signals. My downlink was very strong, above normal, even after lowering my power down almost all the way on my 910H. I heard heavy distortion on my downlink. This was a very high pass for me, about 60 degrees. Leo, W7JPI also confirmed the distortion problem (not just on my signal). He mentioned that had been happening all day. I heard a couple of stations using CW, which also sounded pretty bad. Signals were up and down. Sometimes very strong, sometimes they seemed to disappear. Once the bird was out of eclipse, the signals were almost normal, but not for the entire pass. I also worked W7LRD for a few seconds at 5 degrees. 73 de W4AS On Apr 14, 2010, at 6:43 PM, ps8rf Piraja wrote: I am convinced that the AO-7 is not in Mode C and would make an appeal to all users of the Grand Old Girl using only QRP until your ready reestablishment.

Hello Just got off AO-7, it really sounds not too good. Weak and distorted audio. Like not enough voltage from the 35 year old solar cells. Heard eveything from response to a CME event to being in mode C to being hit by whatever. The audio distortion does not depend on the uplink power, it sounds distorted weather I ran very minimum power or more.

Perhaps some our experts on the bb can shed some of their expertise on what's going on with this old bucket. 73 Bob W7LRD ___ Sent via amsat...@amsat.org. Opinions expressed are those of the author.
