Re: [eu-amsat] Fw: AO-7 2000 QSO.
by John Hackett 13 Dec '07

13 Dec '07

Gene, Here's an explanation. Some days UA9CS Igor works as many as 7 stations on a pass. Each of these stations enters his callsign - 5 or more passes a day gives a *LOT* of points. Now maybe people can understand what I was rambling on about these last months re: "points" in the log. A few months ago, Igor was well behind me, now he's well ahead. It all depends on how active a person is. Note that the actual figures I quote above are THEORETICAL. Igor doesn't always work 7 stations per pass. There were *VERY* few stations who worked AO-7 in the 70's. Mostly Americans. The JH station in 7th place has ammassed several hundred points without one single QSO ... which of course makes a complete mockery of the points system. As I have mentioned on both reflectors several times. The log is an ACTIVITY log ... *NOT* a contest log. The "points" system is an ill-advised design in my opinion - others may disagree. Accumulative errors from sloppy entries will eventually make the log show incorrect results. 73 John. <la2qaa(a)amsat.org> ............................................................. > To: eu-amsat(a)yahoogroups.com > From: genek(a)hot.ee > Date: Thu, 13 Dec 2007 10:27:47 +0200 > Subject: Re: [eu-amsat] Fw: AO-7 2000 QSO. > > Hello group, > > 2000 QSO just via AO-7, this "old bird".... > Hm-m... > How to find so many "uers" of AO-7? > May be he worked via AO-7 during all those 30+ years, even, when > bird was "dead"? > Who has more via AO-7? > May be it was his QSO "number 2000 via satellites" in his logbook? > > Strange, that I meet Igor firstly on satellites only in 2005 (VO-52) > and never before... > In my lodbook only 3843 QSO via satellites (RS, AO-7, AO-10 e.t.c...) > Very poor result... > > 73!

Oscar 1 Anniversary
by Dave Guimont 12 Dec '07

12 Dec '07

First contacts to celebrate Project Oscar 1 Anniversary!! Make one, and get in on the ground floor... Congrats to Rob, G8ATE, for the initiation... Tnx to the following N5ZNL, Rick; N5UXT, Angelo; N2BX, Paul; XE1HON, Manny for making it possible on AO51 Echo.... ~0150Z on 13 dec. I was only running 5 watts uplink, ICOM 910, homebrew self-designed quadrifilars on both up and downlinks, with antennas at ~45° EL, on the same mast, and rotating manually using a U100 rotor ( I think that is the name?? an inexpensive, age-old TV rotor). Freq. control with SatPC32..... Plans for the antennas on my website: http://home.san.rr.com/doguimont/uploads/ quadfil.exe My own downlink was blasting me, and I had a problem cranking the gain down, to listen. ONE contact would have been enough to comply with the celebration....Of course, digital would be possible with you, Rob, but in my opinion a voice or cw contact is the requirement, and impossible with you in the absence of a HEO... So I wasn't HOGGING, just answering those that called me, and pulled the big switch after the aforementioned contacts... Tnx es QSL to them... 73, Dave, WB6LLO dguimon1(a)san.rr.com Disagree: I learn.... Pulling for P3E...

Re: Phase 4 versus Eagle
by Dan Briner 12 Dec '07

12 Dec '07

Tom said "As a Board member I have wholeheartedly embraced the P4 GEO concept as the best (and perhaps only) act in town. I hope that the rest of the AMSAT members are similarly enthusiastic about the idea. As of now, it still is only an idea. It may not happen. But I can guarantee that we are guaranteed to fail if we don't try; and to try we need to know that the community is behind the effort. Remember that AMSAT is an all-volunteer effort, and YOU ARE AMSAT." Well put Tom, if we do not strive to take advantage of the Phase 4 opportunity we will lose the chance to take Amateur Radio to the next level of technology and experimentation. Eagle is a progressive step Phase 4 is a leap. We give up nothing in what needs to be developed for Eagle to peruse the Phase 4. I see our chance to open a whole new dimension for AMSAT and Amateur Radio to be the biggest plus of Phase 4. 73, and best wishes for this holiday season a wonderful New Year Dan Briner AB3EN ab3en(a)amsat.org .- -... ...-- . -.

Re: Phase 4 versus Eagle

Bob and all, Could you estimate how long it will take to be ready for a launch opportunity for(a) Phase 4 and (b) for Eagle (assuming you have the funds to build everything needed for the one selected to go first)? The merits of one versus the other is only relevant if they're both realistic options, and I know that that is not clear now. So going down a path from which you can move in either direction makes sense. My surprise is that there appears to be a strong presumption in some of the messages that Phase 4 should be the higher priority. That may be the case, but I don't think we've been given enough information to agree with it or disagree with it. By the way, will the higher power made available on Intelsat mean that a Phase 4 bird will need a much higher power output? If so, are there any implications for the design? 73, Tony, N2UN

VE3VRW Satellite Gateway Video
by Jeff Davis, KE9V 12 Dec '07

12 Dec '07

Mac users already know the handiwork of Don Agro, VE3VRW. His MacLoggerDX logging application and MacDoppler satellite tracking software is top notch. Don also runs a satellite gateway in Toronto that automatically tracks AO51, AO27, SO50 and ISS and ports the audio into the local repeater network. An outstanding video production of the entire operation can be seen here: http://www.youtube.com/watch?v=8tOJX-oOZ2Q It's very well produced and certainly worth a look! 73, Jeff KE9V

What is *real* ISS APRS frequency?
by jon 12 Dec '07

12 Dec '07

I was googling around to find out the ISS APRS Packet frequency, and I get several answers: Up/Down 145.825/145.825 145.99/145.800 145.800/145.800 What is the correct pair? I am guessing 145.825/145.825. Even Bob gives two different freqs on two different pages. ;) 73s, Jon K7PGB

The new LVB case is here!
by Stargate 12 Dec '07

12 Dec '07

The new LVB case is here! The new LVB case is here! The new LVB case is here! I'm somebody now!! For those of you that have never watched the Steve Martin movie "The Jerk"... You won't understand the pun:-) (sorry) All joking aside, it's a VERY nice looking black "METAL" case with AMSAT right on the front. Nice job to the people that were involved. Now my LVB has a look that matches it's performance. Well done! 73's RoD KD0XX A good friend will come and bail you out of jail, A TRUE friend will be sitting next to you saying.....

Time Hackers
by Tom Clark, K3IO 12 Dec '07

12 Dec '07

Many of you know that I (along with others like W2GPS, N4HY, K8RQ, N8UR etc) have long-standing interest in high-accuracy timekeeping (especially involving GPS). You might find this WIRED article interesting (http://www.wired.com/science/discoveries/news/2007/12/time_hackers). Several of you know about Tom Van Baak (no call) and his time/clock exploits; Tom has been a friend ever since he became interested in atomic clocks. The article doesn't mention it, but Tom (who signs his messages TvB) has TWO hydrogen maser clocks in his lab. Photos of the clock labs at TvB and N8UR home QTHs, see the gallery at http://www.wired.com/science/discoveries/multimedia/2007/12/gallery_time_ha…. In the article you will also find mention of John Ackerman (N8UR) in Dayton. John has served as TAPR's president and has recently helped TAPR/AMSAT in developing a GNU-like Open Source Hardware license. For those of you interested in the topic, N8UR runs the "Time Nuts" Email listserv. Details can be found at https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts. 73 & Seasons Greetings -- Tom

Phase 4 versus Eagle
by tjjapha＠earthlink.net 12 Dec '07

12 Dec '07

Hi all, A very interesting set of exchanges indeed. I nearly fell out of my chair--and not because of old age--reading some of Rick's comments, viz. Amsat will move ahead with Eagle IF WE SO DESIRE! Wow. There has been a very significant change in direction that we have not been informed of. My understanding has been that Phase 4 (Intelsat) would be pursued in tamdem with Eagle. This is much more than a change in tone. Please tell us directly: Has the Board made the judgment that Eagle can't be done because of a lack of affordable launch opportunities? If that is the case, it's a great shame, but we'll have to accept it. The development work apparently can be exploited for Phase 4. Given a choice between Eagle and Phase 4, my vote would go to Eagle. But, again, please tell us directly: Has the Board made the judgment that it is highly unlikely we will have both? If that is the case, then the Board should spell out the likely costs of each, both development and launch costs, and also spell out their current reading regarding the likelihood that each can be launched, and WHEN. With that information, the members could inform the Board of their opinions. A firm decision should be made, and, from the sound of some of the exchanges here, made soon. We need more information than we have if we are to advise the Board of our choices. 73, Tony, N2UN, LM-183
