All: Have a few questions about the RS-12/13 robot QSL. I made contact with the robot a while back and have a recording of the "QSO" with contact number and all. Problem is, I can't find the paper log I was using at the time. Is it possble to obtain a card with just the QSO number? Are they still issuing robot cards? Thanks, Tony K2MO

satellite software engineer
by Jim White 29 Jul '07

29 Jul '07

Software Engineer Needed The US Air Force Academy has an opening for a software engineer to work on satellite and ground station software. This is an unofficial announcement of this opening. A formal announcement should be out shortly. I’ve just retired from 10 years in this position and can say it is without question the most fun I’ve had in 40 years in the software and space business. This is a full time contract position in the Space Systems Research Center and is located in Colorado Springs, Colorado. This engineer is involved in every aspect of satellite design and construction including working with students, writing software, testing, launch campaigns and on orbit operations. The USAFA small satellite program is one of the most successful in the world having launched and operated three satellites (one more was lost to a launch failure). Falconsat-3 is currently on orbit and undergoing commissioning. Two more of the Falconsat series are under design and construction. This position also works with the sounding rocket program on the avionics and telemetry packages and with the Eyassat classroom satellite (www.eyassat.com) in the Astronautics Department. Existing systems include ANSI-C, Visual Basic, and real time operating systems. Future work may include embedded Linux, Visual C, Java, and LabView. Experience in all these areas is not required but the ability to learn quickly is essential. This is an opportunity to work in the exciting small satellite field and with motivated and dynamic faculty and students. And Colorado Springs is on the doorstep of the wonderful recreation opportunities of the Rocky Mountain region. Interested parties should contact LtCol Tim Lawrence at timothy.lawrence(a)usafa.af.mil. Jim White WD0E jim(a)coloradosatellite.com

RS-15 beacon heard over Europe
by Henk, PA3GUO 29 Jul '07

29 Jul '07

>From the newsgroups: rec.radio.amateur.space I picked up this report on RS-15: > Sent: Friday, July 27, 2007 10:12 PM > Subject: RS-15 > > After a period of very intermittent appearances, RS-15's beacon has been > audible on most passes during the last three weeks or so. Its frequency > has fallen to ~29.35165MHz, and sometimes there's a near-continuous > carrier rather than the usual short, chirpy pulses, suggesting that the > voltage regulation may have failed. Catch it while you can! > > -- > Hil As it had been over 10 years that I had heard this satellite I decided to give it a go. Using the TS-2000 and a simple 14MHz dipol, no pre-amp, I was able to hear the beacon. Quite weak, but audible. Frequency as in the report; 29.3156MHz (assume this to be Beacon 1). On my website I have placed an mp3 recording and some 'waterfall' graphics: http://www.qsl.net/pa3guo You hear & see the beacon being switched on (~2 seconds) and off (~3 seconds). Also you hear & see the beacon 'tuning in' to the correct frequency every time it's switched on. Looking forward for your comments/feedback/experiences ! Henk, PA3GUO

JAMSAT and P3E News
by Jeff Davis 29 Jul '07

29 Jul '07

Peter Gülzow, DB2OS reports on the DL Web site that JAMSAT (Japan) has made a generation donation of 1,000,000JPY (7500.00 euro) in support of the AMSAT P3-E satellite project. He went on to say that Mikio Mouri, president of JAMSAT is working on the structure of a command station for P3-E in Japan. There is close cooperation with the University for communications technology and the radio observatory in Sugadaira/Nagano to re-equip their 4m parabolic antenna for command use with P3-E in the 23cm and 13cm-Band. You can read the entire release (German) here: http://www.amsat-dl.org//index.php? option=com_content&task=blogcategory&id=35&Itemid=97 Congrats to JAMSAT for their strong support of amateur radio in space! -- 73 de Jeff, KE9V

Now back on Sats!
by John Geiger 28 Jul '07

28 Jul '07

After being off the satellites for a year or more due to the lack of a 70cm antenna, I finally put up a Cushcraft A270-10S dualband yagi. It doens't receive quite as well as the 719B I used to have, but did make 2 QSOs tonight on AO51 with it. It is great to be back, and AO51 sounds as good as ever! Look forward to meeting everyone on the sats again! 73s John AA5JG (ex: W5TD, NE0P, N0EEN, KA0IFG) Sat VUCC #129 Yaesu FT100D to Cushcraft A270-10S

Sputnik recollections wanted for CQ
by Rich Moseson 28 Jul '07

28 Jul '07

Hi all from CQ Editor Rich Moseson, W2VU: The 50th anniversary of the launch of Sputnik is coming up in October, and we are currently working on our October issue. Many of you remember the launch well, and of course, hams were in the vanguard of listening for those beeps from above. We'd like to collect a representative sampling of your first-hand recollections to weave into an article for our October issue. Plus, we'd like to hear if this experience had a significant impact on your choice of careers, etc. - in short, did listening for Sputnik change your life? If so, how? Please respond as soon as possible by e-mail directly to a special mailbox we've set up at <sputnik(a)cq-amateur-radio.com>. Many thanks in advance and 73, Rich W2VU

IC-821H TX problem on 70cm
by Scott Townley 28 Jul '07

28 Jul '07

Wondering if anyone else has experienced this: My IC-821H will just "quit" transmitting on 70cm. The PTT is still engaged in the radio (at least the band LED is red) but no RF comes out. This happens in either CW or SSB. The length of time it takes to quit varies, sometimes a couple of seconds, sometimes a minute, but it always happens eventually. If I let it set for several seconds, it always comes back, but not necessarily the first time I try. Needless to say, this puts a bit of a crimp in operations.

Question on diode symbole designation
by i8cvs 27 Jul '07

27 Jul '07

Hi All, After many attemps to trouble shoot why a new circuit was not functioning to me I found a diode IN4006 made by ITT wrongly marked reversed i.e. with the white ring printed to the anode side |! This diode if reversed is perfectly functioning and it is a rare one good for collections like a wrongly printed postage stamp. Any similar experience ? 73" de i8CVS Domenico

AO-51 SSB/FM mode
by Patrick McGrane 26 Jul '07

26 Jul '07

greetings Thanks for trying the AO-51 SSB/FM mode. It was interesting. I made a few contacts. I noted the audio level was a bit low so it was tough to hear myself on the downlink but I quickly turned up the volume and withstood the load static noise. I was wearing headphones. It was interesting to note that matched uplink and downlink modes are clearly heard on the various satellites. Is it that the narrow band SSB doesnt fully drive the transmitter deviation? Might sound stupid but I'm curious. Thanks to VE3NPC, KD8CAO,N5ZNL,W2NBJ, and KC8ZFN for the brief contacts. 73, pat

See: > > http://www.findu.com/cgi-bin/find.cgi?call=N8PK-11 Now you will see its final report on the APRS system (at 705 feet and zooming down at 4000' per minute!). Be sure to select the SATELLITE image to see the field it landed in. See the following image to see where it finally landed after that last 705 feet: http://www.ew.usna.edu/~bruninga/aprs/DF-ing/N8PK-11_recovery.JP G The field was full of crops and I could not see the balloon until I was 20 feet away, even though the crops were only 1 foot tall!. To see how I could find it with nothing but an HT, see my new images on the APRS DFing web page (about 70% down the page). Look for the topic "HT-ONLY Dfing:".... Follow the 5 links to the 5 maps as we zoomed in with nothing but an HT. http://www.ew.usna.edu/~bruninga/dfing.html What a fun time had by all. More to come. Lots of photos...

While demonstrating satellite communications to a Radio Amateur visitor at the Canada Sci and Tech Museum in Ottawa, VE3JW made 3 contacts in the new mode while trimming Doppler manually on the USB uplink. A little tricky at first... but great to hear on the same pass Northern Alberta (Edmonton), USA and Mexico. ( the 15--UTC pass 25 July) Thanks for the experience, my visitor was impressed. 73 de VE3VIG Maurice-André ve3vig(a)rac.ca

To those whom it may concern, The AO-7 log has been getting "sloppy" of late. <http://www.planetemily.com/ao7/ao7log.php> Therefore I have decided from today, the 25th of July 2007, I will continue to administer and edit the log for the convenience of the regular users. Please remember ... it is designed to be an "activity" log ... not !!! a log to see who can collect the most points so please refrain from entering multiple QSO's on different lines for the same orbit ... because this will then give false overall results. Just follow the examples of K3SZH or G1WPR. If you do make a mistake, please correct it by clicking on the hourglass to edit your entry. You can edit your own entry but not other people's. If you need anything other than your own entry edited, you can either use the online contact form or e-mail me direct. 73 John. AO-7 Resource Page Admin: <la2qaa(a)amsat.org>
