[email protected] need L-bracket to combine g-5600 yaesu/kenpro az/el rotator
by rafus 01 Aug '07

01 Aug '07

ordered a combining L-bracket from yaesu and received one shaped in the form of a "u" this type will not work with my elevation rotator (kenpro) which is drilled and tapped on one side only.I am in need of the correct bracket if you have one please contact me bill rafus at kd4frb(a)amsat.org ________________________________________________________________ Sent via the WebMail system at webunited.com

Re: AMSAT IRC Channel on Freenode

I got quite a few responses off the -BB so I figured I would pass this information along. There is an IRC channel in use at irc.dishnuts.net #amsat. 73s, Eric W4OTN >A friend of mine and I were chatting on freenode IRC and was wondering if >there was an AMSAT room.

Hello Patrick McGrane. Thanks for your comment. Today also I received AO-51 signals with TlmEcho. I noticed that the inner clock of AO-51 was 15 minutes fast. http://www.ne.jp/asahi/hamradio/je9pel/ao51tlmg.htm

AMSAT IRC Channel on Freenode
by Eric H Christensen 01 Aug '07

A friend of mine and I were chatting on freenode IRC and was wondering if there was an AMSAT room. When we checked there was not so we unofficially established one to see how much interest there would be. This could be a low-bandwidth back channel that AMSATers worldwide could join into and chat in real time about satellites, during passes get feedback, or people could come to get assistance when they are having problems. I know the IRC channels are being used for the same reason for other projects, why not AMSAT? If you already have an IRC client come join us at irc.freenode.net and join channel #amsat. If you aren't sure about what IRC is take a look at http://en.wikipedia.org/wiki/IRC. Of course I'll be happy to field any questions here. 73s, Eric W4OTN AMSAT Area Coordinator

Attention: Mineo Wakita This is patrick N2OEQ, Long island New York Mineo- thank you very much for hosting and posting the website with the Echo telemetry. It was very educational. I dont have 9600 baud capability so I cant recieve the telemetry myself. Please post again from time to time. 73, pat

Re: [eu-amsat] AO-7 report.
by John Hackett 01 Aug '07

Drew, It is my understanding from recent correspondance with W3GEY/VK3GEY Jan King ... (Jan 'built' AO-7) ... and earlier correspondence with N1JEZ Mike Seguin (AO-7 control operator) when I first posted the mail re: the timer last year .... that the timer is completely random when the satellite comes out of eclipse and since there are no imminent occurances of eclipse as far as I can see, I assume the mode will not change unless anything 'ontoward' occurs to upset the electronics. High power *can* affect how the control systems behave ... (obviously, I'm not going to mention the command parameters or the power required). If my assumption is wrong, I stand corrected. In either case, listening to the regular operators will confirm the mode. The mode changes can be viewed at ... <http://www.planetemily.com/ao7/stats2.php> The predected eclipse chart at ... <http://www.planetemily.com/ao7/Eclipse.php> Perhaps other operators will obtain different conclusions from the above predictions. Opinions are are invited. That is, after all, precisely why we started the EU-Amsat reflector. I CC'd this mail to the amsat-bb since the number of Stateside users has increased in the last 2 months and this information may be of interest to them too. 73 John. <la2qaa(a)amsat.org> ........................................................................................................................................... >From: Andrew Glasbrenner <glasbrenner(a)mindspring.com> >Reply-To: eu-amsat(a)yahoogroups.com >To: eu-amsat(a)yahoogroups.com >CC: amsat-bb(a)amsat.org >Subject: Re: [eu-amsat] AO-7 report. >Date: Tue, 31 Jul 2007 11:18:04 -0400 (GMT-04:00) >Every time this has happened in the past, several times over the past few >years, the 24hr timer has >activated, switching between A and B.
