Owen and Richard Garriott
by ka3hdo＠comcast.net 29 Oct '08

29 Oct '08

All, I received the following e-mail today from Owen Garriott, W5LFL and wanted to share this with the Amateur Community. Please post this and pass it to others in the amateur radio community, as appropriate. 73, Frank H. Bauer, KA3HDO AMSAT-NA V.P. for Human Spaceflight Programs ARISS International Chairman --------------------------------------------- Richard, W5KWQ, landed in Kazakhstan on Friday, 24 October 2008 at about 0936 local time and was met there by his father Owen, W5LFL. They became the first American "second generation" father/son combination to have both flown in space and the first cosmonaut/astronaut-trained pair in the world. They returned to Star City near Moscow that afternoon for medical evaluation and this is the first interview provided by Richard the very next day. It is transcribed and delivered by Owen to the ham community. "On my recent flight I had the great opportunity to speak directly with and trade call signs with hundreds of hams around the globe. For me it was a unexpected joy to find so many enthusiastic hams, who were so well informed and interested in my activities in orbit. When I began my transmissions with preplanned SSTV images including "pirate messages", test patterns and family images, I did not know how they would be received. But it seemed that fellow hams really enjoyed seeing this beginning to my time on the International Space Station (ISS). Throughout the bulk of my 10 days on the ISS I tried to be speaking by voice or transmitting SSTV images whenever possible. After my first 100 or so QSOs, I understood how well "networked" the global ham community really is. I received specific reports back through Mission Control-Moscow about technical aspects of my work and how the community was enjoying the transmissions. This redoubled my enthusiasm to do quality work for the amateur radio legions around the world as I realized how much it meant to those with whom I had the chance to talk. By late in my flight I had contacted many hundreds of hams by voice and I have good records of these contacts. Finally I sent some "Goodbye" images on my last day in space. I also contacted many hams that had listened to or contacted my father from space 25 years ago. Some hams I contacted 2 to 4 times on my flight. On those last days I was very moved when sent many "soft landing" messages from individuals and classrooms full of children as I passed by. The ham community has added greatly to my personal feelings of success on my flight. I can only hope that you enjoyed it as much as I did. Thanks so much and 73, Richard, W5KWQ"

ic 970 (Dimitrios Pallis)
by RFI-EMI-GUY 28 Oct '08

28 Oct '08

Dimitrios; I own two of them. I have the UX97 and UX98 1.2 and 2.4 GHz modules (very hard to locate in US). Although I have not been active since moving a few years ago, I have been very happy with the IC970. Very easy to operate, excellent LCD panel to look at and great performance. One troublesome area is the UHF VCO. One of mine went out of lock and it was necessary to disassemble the sheild and replace the tuning capacitor, Getting it retuned was a snap. Hardest part was the small bottom shield to remove and replace. I think the only drawback is lack of availability of the microwave band modules. Otherwise they have continued to hold value on the resale market. -- Joe Leikhim K4SAT "The RFI-EMI-GUY"© "Treason doth never prosper: what's the reason?

Printed copies of Brit publicity of Garriott flight
by andy thomas 28 Oct '08

28 Oct '08

After sending one to Richard Garriot himself c/o Space Adventures, one to ariss-eu and some to friends in the UK, I have 3 copies left of the newspaper "Market Harborough Herald and Post" that printed 3 of Richard Garriott's ARISS SSTV pictures. The text is on a previous posting - this has 3 smallish photos I received off air. If anyone wants a copy - worldwide - please email me off line. Personally I always like the complete edition of a newspaper so that you can see what else was thought to be important in that community at that time. I'll cover postage costs. Any more than 3 and I'll email a scan of the article with photos. 73 de andy G0SFJ

AO-51 Mode
by John Marranca, Jr 28 Oct '08

28 Oct '08

Hey Everybody! OK, Drew....is it possible to put AO-51 into the same unique mode that AO-16 is in (145 FM UP/435 SSB DOWN)??? I would be interested in trying it on AO-51. How about more QRP on the 2nd Channel? OR...Can the Up and Down links be reversed...as in 435 up and 145 down???

AMSAT symposium - what happened?
by David Giles 27 Oct '08

27 Oct '08

Hello to all those who attended Atlanta, Apart from a new vision statement and a BOD meeting, did anything actually happen at Atlanta? I haven't seen the usual "What a great symposium.", "It was great to catch up with ...", "I was inspired by the ...", "Demonstrations of... were held", "Hundreds of new members", or "Well done to the organisers" type messages. I haven't even seen the usual announcement for the 2009 event. Perhaps there won't be one - that would be newsworthy in itself. Don't get me wrong - I'm not knocking the event. It just seems unusually quiet. 73 de David VK5DG

Jan and others, the article is available on PDF at the ARRL website for download.
