AMSAT opportunity for Windows programmer
by Andrew Glasbrenner 07 Jan '07

07 Jan '07

AMSAT-NA has two opportunities available for Windows programmers. We have two projects that are in need of talent, both in support of Operations. This is a great chance to support AMSAT and amateur satellites in a real and tangible way The first project involves writing a GUI XP compatible program to read mixed ASCII and binary telemetry files, extract, reformat, and display the data. Some basic statistics and producing a .csv file are also highly desireable features. Console versions of these programs already exist created in Visual C++ 2005 Studio Express. Support for the finished product will be limited to a few internal users in support of AO-51. The second project involves developing a GUI XP compatible program around some prexisting AX.25 and soundcard code for a UI satellite communications program. Ease of installation and use are high on the priority list for this project, and support will be required for widespread use. A team approach may be best regarding support (read this as "bring a team with you"). This will be done in support of an effort to increase usage and visibility of the several Microsats currently in orbit and functional. Please send a e-mail to ko4ma(a)amsat.org indicating your willingness to help, and I'll be happy to explain further. 73, Drew KO4MA AMSAT-NA VP Operations

PACSAT system
by William Leijenaar 07 Jan '07

07 Jan '07

Hi AMSATs, Due to my qrl I have not so much time and energy to get qrv on the satellites anymore. I am more happy with designing and making new transponders haha... In the last months I finished a new transponder design that is very small in size, relative cheap to produce, good in RF performance, and changeable to other bands. More info will follow later as I am still improving it. Now I have the transponder design I am thinking to make an additional PACSAT system like in UO-22 or KO-25 etc... My main problem is the software, as I am better in RF designbing than in programming (although I will manage some way to make it). I would like to know if there is any software, data or kind of flow chart available from a PACSAT (satellite) system ??? With todays low-power-high-speed processors with lot of memory on chip it should be possible to make a small version of a PACSAT system, isn't it ?? It can be very interresting for balloon missions. Data and pictures can be stored by the OBC and later downloaded by users, like with the WO-18 and GO-32 once was possible. With a battery, solar panels, a box and a rocket we even might have a new satellite :o) 73 de William __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

Uni_Trac question
by Bob DeVarney W1ICW 07 Jan '07

07 Jan '07

This is probably a repeat of a recent question, but I just dusted off the sat gear after a hiatus of 2 years, and now have a few quirks. I am using the Uni_Trac 2003 parallel version, and after updating the keps today, I now have an " error in NORAD 2 element file ". I've pared the text file down to the absolute minimum of sats that I will be using, and also removed any extraneous characters that looked out of place ( like the plusses and minuses that have been added in the Celestrak file ) Anybody have a clue what I'm doing wrong? I am also interested in making multiple entries for the same satellite ( AO-51 ) so I can track automatically in V/U, L/S and digital mode, and can't remember how to set that up. I would have posted this to the Uni_Trac reflector, but can't remember the address for it. Thanks and VY 73, Bob W1ICW

Oscar 58 Pass
by Steve Raas 07 Jan '07

07 Jan '07

Hello Everyone . I just received the Oscar-58 beacon on 437.4650 and have a question. I have read abt dopler shift and how It can affect radio signals especially with the sats. This being only the 3rd time ive ever even herd a sat I was shocked to note that the frequency drift was a few Hz lower on every cw note ( the beacon ). It reminded me of an old heathkit HF radio that drifted .. but never settled down. Is this about the normal expected Doppler Shift in a cw/ssb signal on the amsats? I was constantly turning the VFO ever so slightly. Or is this more on par for this particular Sat? Thanx! -Steve N2JDQ

AO-51 1st reception
by Steve Raas 06 Jan '07

06 Jan '07

Well as some of you know.. I am in the midst of setting up a small sat station. I received my antennas yesterday, and was up till 3 am building them. I am waiting on my feedlines to come in.. but have been tinkering with the 432 yagi today. I decided to try and strongarm the 11 element yagi in my hand and listen to 435.300. as the bird came up 2 passes ago I herd a brief signal then gone.. I waited till abt 15 minutes ago to try again and WOW AO-51 LOUD AND CLEAR from abt 7deg el to LOS. My kids ran down stairs and wanted to know if that was the ' Space Ship ' I have been trying to hear.. And I replied YES! I have never herd a sat before.. and this was arm chair copy with the yagi in my hand @ ground elevation. I cannot wait to get my feedlines so I can get the final installation done and get a sig on the air. Thank you all for your continued help. -Steve Raas N2JDQ
