Re: [amsat-bb] LituanicaSAT-1 Transponder Off
CW Telemetry beacon, as decoded by FLDIGI here in CM98 on the 6/2 0600z pass. My rotor controller doesn't do flipped operation, so the 3rd frame got trashed by the rotor needing to swing around as the satellite passed through North. Some errors in the frames, but for the most part, during the frame itself, the signal was full quieting. It seemed like the very front of the frame (call sign?) was at a low power setting, then jumped up for the main part, and then at the end a few dits, seconds apart, at low power. This was my second attempt (first success) at copying the beacon.

Re: [amsat-bb] Orbit Decay - SatPC32, Calsky, DK3WN/N8MH, Orbitron
Hello Tom, the program WinAOS gives you a quick overview of the satellite passes in the near future. The program is not designed for long term calculations. It doesn't use the SGP4/SDP4 model as SatPC32 and WinListen do but uses rather simple calculation routines. Therefore use WinListen or the Preview function of SatPC32 for more precise calculations. 73s, Erich, DK1TB Am 02.06.2014 00:10, schrieb Thomas Doyle: Some of you may remember the Chicken Little Contest run by Alan a while back. I have taken another look at decay using the XATCOBEO satellite as an example. My first try at a program calculated the decay in early June 2014. I am all but positive this is several weeks too soon. On the other end of the spectrum SatPC32/WinAOS shows it up and running well into 2084. I am as positive as I can be that this is many decades too late. Orbitron shows it still running on Sept 8 2014 but at an altitude of only 109km. I believe this is a bit late as 160km is usually considered to be the point of no return. Calsky predicts decay on 14 August 2014 with a +/- of 15 days Smart guy to hedge his bets with the +/- range. DK3WN predicts decay on 31 July 2014 This falls into the +/- range of Calsky and since our own N8MH is an editor on this site it is probably the closest. With LEO satellites rapidly becoming as common as iPads they provide interesting subjects for decay predictions and possible Chicken Little contests. Is there any formal definition/announcement of the actual decay or are satellites like old soldiers and just fade away ? 73 W9KE Tom Doyle ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] About ARTSAT1:INVADER
Hello, de ji1izr/Masahiro, ARTSAT1:INVADER, one of the CubeSats, is in trouble that the satellite does not reply after the command by the comm nad station. The members are trying to find out how to recover. We have no reply from the satellite, nor the CW becomes not to be heard after the command. When you have a chance to listen to the satellite, please send your report from below: http://api.artsat.jp/report/ Your report will be great help for the members. We appreciate your help very much.

[amsat-bb] Keeping KPC-9612+ KISS mode in port 2
I've been asked to attempt some communications with a 9.6k satellite which requires KISS mode. My problem is that when I set the KPC-9612+ to port 2, the 9600 baud port, then using HyperTerm to issue the INTFACE KISS followed by RESET, the TNC returns to port 1. There must be some way to either keep it set to port 2 after KISS is entered, or enter some magic keystrokes to set it to port 2 while in KISS. Anyone have the answer? The manual wasn't any help.

[amsat-bb] Trakbox pricing ?
Hi Gang I'll be selling a Trakbox soon; would be grateful for advice on what price to ask (in UK money). Original price AFAIRC 100-150 UK pounds. For those who don't know this item, its an az/el rotator controller. Feed it keplers on the RS232 input occasionally and it'll track both rotators at the right time. 73 Richard G3RWL ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author.

Re: [amsat-bb] Sat Talk in Fullerton, CA
What an extraordinary session tonight at this club - WARA in Fullerton, CA. I was last there five years ago ... they continue to grow ... and teach ... a new ham graduate from one of their test sessions was there ... we guided him to what to purchase this week at HRO-Anaheim ... After performing my satellite presentation about 80 times, I thought I had heard 'bout all the possible questions that may arise. But this wise group hit me with a couple inquiries that I had never been asked before. (Proving to me that they WERE listening ... (grin).) And what better way to finish a satellite presentation than to walk outside on a beautiful evening and watch the International Space Station streak across the sky above us. It was the very first time for EVERYONE in attendance to actually SEE the ISS pass overhead ... SO - THANK YOU, Western Amateur Radio Association, for your hospitality this evening. And if anyone reading is in or near Orange County, CA, then please cruise the WARA Web site cited below and give them a visit. http://www.warahams.net/ Clint Bradford http://www.k6lcs.com ___ Sent via AMSAT-BB@amsat.org.
