ISS QSOs
by Jeff Yanko 06 Mar '09

06 Mar '09

Hi all! I know this might not be proper procedure but I finally found the time to get on one of the birds tonight, ISS. I managed to work two stations. One in San Francisco and the other was an "8" call around 0650z. My problem...no place to write anything down and standing out in the backyard with a TH-D7A(G) in in one hand and an Arrow antenna in the other! I know, a tripod is on the agenda. :) Please drop me a note! 73, Jeff WB3JFS

Hi All, I would like to thank all the stations from IN to TX and GA to CA and all in between for the contacts last night during my demo at the MARA club meeting in Memphis. 73 from Memphis, Rick - WA4NVM

SK: Mario Acuña, LU9HBG
by Tom Clark, K3IO 06 Mar '09

06 Mar '09

It is with great sadness that I learned today of the passing of a long-term friend of AMSAT, Mario Acuña, LU9HBG. Mario was a very senior scientist/engineer at NASA Goddard where he made his name by providing magnetometers for nearly every deep-space and planetary mission since the 1970's. His vitae can be viewed at http://ssed.gsfc.nasa.gov/vitae/acuna.html, and a nice writeup on him can be found at http://www.nasa.gov/home/hqnews/2005/jan/HQ_05022_acuna.html. Mario never bothered to get a US call, although he often had HF schedules with his relatives & friends in Argentina. In years past, Mario and I were contemporaries at Goddard, and we often commiserated about NASA's problems of "getting old"/"mature government bureaucracy" and about the dearth of young innovative scientists who enjoyed inventing new instruments. His loss hits me especially hard. When a young Martin Sweeting wanted to fly magnetometers for navigation on the earliest UoSAT's, Mario was the "go to" guy that put Martin on the right track. Since magnetometers are biased by metal and electrical currents in a spacecraft, Mario arranged for testing of the early UoSATs. When Jan, Karl and I were trying to minimize radiation damage in critical Phase-3 components (like the IHU and CMOS logic), Mario was our mentor in helping to figure out the best way to minimize damage and teaching us how to apply tantalum to the top and bottom of ICs. ------------------------------------------------------------------------- GSFC Director Rob Strain posted this note earlier today: > From: On Behalf Of GSFC-PAO > Sent: Thursday, March 05, 2009 3:05 PM > To: gsfc_all(a)listserv.gsfc.nasa.gov > <mailto:gsfc_all@listserv.gsfc.nasa.gov> > Subject: Center Director Mourns Passing of GSFC Employees > > Colleagues: > > It with profound sadness to inform you that Goddard has tragically > lost several members of its family in the past few days. > > Dr. Mario Acuña, a Senior Astrophysicist in the Planetary > Magnetospheres Lab, passed away last night, in the comfort of his > home, surrounded by his family and loved ones.

A0-51 V usb/U fm
by Gary Lockhart 06 Mar '09

Thanks Tim (N3TL) for QSO on AO-51 in V (USB) / U (FM) mode. You and a few others were coming in 59 but there were still other strong unintelligible stations out there. Cute trick for the satellite repeater to take USB uplink and transmit an FM downlink. 73, de Gary AB3ID

Old Mum (AO-7 ) needs TLC
by Nader Omer 05 Mar '09

05 Mar '09

HI Monitoring a vital signs for a patient who has been in coma for more than 20 years at the ICU is so valid and so interesting to all the medical practitioner or medical doctor around the word .for sure many vital sign well not be stable but as long as the patient is alive you need to check those vital sign and keep your eyes on any simple changes. It is so interesting to be part of history and it is fun and education. No harm to monitoring old Mum (unstable) vital signs. She needs TLC (tender love care) 73's Nader , st2nh www.st2nh

No current production full-duplex HT's?
by Dave-K7DAA 05 Mar '09

05 Mar '09

Folks: Sorry for the bandwidth, but I know this question comes up here periodically. I've looked around quite a bit, but I can't seem to locate any newer information about whether or not there are any _current_ production HT's capable of transmitting on 2 meters while simultaneously listening on the 437 downlink for use with the FM sats. As far as I can tell, that answer is "no", but I wanted to make sure that's the case before I go looking for a gently-used Icom W32A or similar older unit. I'm tired of the "excitement" of having to transmit in the blind when operating portable on SO-50! That got old the first time I tried it late one night when there was no activity on an overhead pass, had to try to switch on the TOT, then guess whether I had actually done it correctly, etc... Thanks in advance, Dave - K7DAA

Fun pass of AO-51
by John Price 05 Mar '09

05 Mar '09

Thanks to the control team of AO-51 for the FM/SSB mode on the bird. The 23:50z pass this evening was much fun. Signals were very strong for the most part. I turned my power down to the end of the knob and still was loud. Antenna gain no doubt. Well I sure enjoyed something different and hope you guys did too. Hope to see more of the same in the future. What a go guys! 73's << John -- N4QWF Amateur Radio Operator AO-7,AO-27,SO-50,AO-51,VO-52,ISS Email N4QWF(a)AMSAT.ORG Echolink nodes #110903 -L #388463 http://home.comcast.net/~n4qwf/site/ Formerly KC4AHW VK3FEZ Amsat Member #27845 DXCC #33,478 VUCC SAT #135 WAS SAT #296 51 on AO-51 #13 LON -79.256 LAT 37.459 Grid FM07il >From the Foothills of the Blueridge *Life should not be a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and loudly proclaiming - "WOW, What a ride!"

Hi All, I have the pleasure of talking about Satellite operations to one of the local Memphis clubs tomorrow, March 5. The Mid-South Amateur Radio Asso. meeting starts at 7 P.M., so I will try to make a few contacts on the A0-51 pass at 0050 utc (6:50 pm local time) right before the meeting. I only get 23 degrees max. to the west and will be using an Arrow and 2W HT. I would appreciate any contacts on the upper pair. (145.92/435.300) Thanks and 73, Rick - WA4NVM LM1339 P.S. Just had a nice contact with VE3NPC on the "bent pipe" pair of A0-51 (2220 utc)

AO-51 V/u
by KC2PCR 04 Mar '09

04 Mar '09

Sounds like you may have heard me on AO-51 yesterday- kc2pcr " Strong unintelligible signals for the most part" could have been me tx in USB because that's what it sounded like coming back to me too, then I switched to try LSB and BAMM! I was in there pretty solid & fairly clear, but it was late in the pass so I couldn't hold it for only a moment or two. I didn't hear anyone else in there however Dave KB2MPU helped me get my TS-520 with 2m tv-502 transverter dialed in prior to the pass was also on freq listening and he told me afterwards he copied a few stations calling. LSB seemed to repeat clear verses USB which came back to me garbled. Take care & 73 doug kc2pcr Message: 5 Date: Tue, 3 Mar 2009 15:33:39 -0800 (PST) From: Gary Lockhart <gary_lockhart33(a)yahoo.com> Subject: [amsat-bb] AO-51 V/u usb To: amsat-bb(a)amsat.org Message-ID: <779929.12530.qm(a)web65614.mail.ac4.yahoo.com> Content-Type: text/plain; charset=us-ascii 435.150 FM 145.880 USB What did I get wrong?
