The following was received from K.V.Prasad,VU2RRG/ROC, National coordinator, AMSAT-IN.
It is with profound grief and sorrow that we express the accidental demise of our most revered ham technologist shri Nagesh Upadhyaya,VU2NUD. He is a noble soul who remains in our ham technologists minds and hearts. His dedication and valour will forever inspire the young ham technologists and future generations of scientists towards higher glory.
A devoted and dedicated scientific officer/ham technologist from AMSAT-IN left for heavenly abode. Its pride to the National International fraternity of AMSAT ham technologists/scientists to have such a dynamic star. May God (the most beneficient & the merciful in the world) bless his noble soul.

SB SAT @ AMSAT $ANS-203.02 Satellite Demo Leads to Successful First QSOs
AMSAT News Service Bulletin 203.02 From AMSAT HQ SILVER SPRING, MD. July 22, 2007 To All RADIO AMATEURS BID: $ANS-203.02
Since March, Patrick, WD9EWK/VA7EWK has been conducting a series of satellite operating demonstrations at the Thunderbird Amateur Radio Club. W7TBC in Glendale, a suburb of Phoenix, Arizona.
At the club's June meeting, kits for a WA5VJB "Cheap Yagi" for the FM satellites were distributed consisting of 2 elements on 2m, 5 elements on 70cm, plus the 2m/70cm "duplexer" or band splitter. Other Thunderbird club members were ready to try FM satellite operation via AO-51 with the telescoping whip on their HT.
Two Thunderbird club members made their first satellite contacts under Patrick's mentoring. He reported, "Jeff W0NWA worked Bernardo 6I2HWB in southern Baja California (DL44), and Bob K7UNL worked me followed by Jeff, K7WIN in southeastern Arizona." Patrick made a total of 8 contacts on that pass. Other club members were able to hear AO-51 for the first time.
Patrick summarized, "The weather was still 105F/41C outside with a bit of humidity. We had a great time, and for a couple of the club members they now have satellite contacts for their logs. We may do another of these hands-on demonstrations in a few months, when it is not so hot outside."
Thank you to Patrick, and congratulations are in order for the Thunderbird Amateur Radio Club!

SB SAT @ AMSAT $ANS-203.04 OSCAR-11 REPORT - 16 July 2007
AMSAT News Service Bulletin 203.04 From AMSAT HQ SILVER SPRING, MD. July 22, 2007 To All RADIO AMATEURS BID: $ANS-203.04
I have now updated the telemetry archive on my website to include all the telemetry received in 2007. The news archive has also been updated. The URL is www.users.zetnet.co.uk/clivew
During the period 15 June to 15 July 2007, no signals have been received from the satellite's 145.826 MHz. beacon. I have not received any reception reports.
The satellite is currently subject to solar eclipses, which will continue until 20 August. The duration of the eclipses is now decreasing and will reach a time of 10 minutes, around 10 August. At that level the satellite may be able to sustain continuous operation, however it is not possible to predict when the satellite will switch ON. If there was failed attempt to switch ON just before 10 August, then it could be the end of August before the satellite resumed continuous transmissions.
The battery can no longer power the satellite during the eclipse season. When the battery voltage decreases to a preset level, the watchdog timer resets, and the beacon is turned off for approximately 21 days. When the satellite restarts, eclipses could cause the beacon to switch OFF, after a short time, probably less than one orbit. This short transmission could occur any where over the world, and could be repeated at 20.7 day intervals.
Owing to the lack of accurate timings, it is impossible to predict when and where the satellite will be heard during these short transmission periods. It is just possible that someone tuning around 145.826 MHz. may hear the satellite, by chance.
The Beacon frequencies are - VHF 145.826 MHz. AFSK FM ASCII Telemetry UHF 435.025 MHz. OFF S-band 2401.5 MHz. OFF
Listeners to OSCAR-11 may be interested in visiting my website. The current monthly bulletin contains further details of the satellite's status. If you need to know what OSCAR-11 should sound like, there is a short audio clip for you to hear. The website contains an archive of news & telemetry data. It also contains details about using a soundcard or hardware demodulators for data capture. There is software for capturing data, and decoding ASCII telemetry.

1. ARISS Contact with Canadian High School Students
Manitoba high school students attending the Manitoba Space Adventure Camp held at the Canadian Air Force 17 Wing in Winnipeg spoke to Clay Anderson, KD5PLA, on Thursday, July 12. During the Amateur Radio on the International Space Station (ARISS) contact, Anderson answered 18 questions posed to him by twelve students, while other camp attendees and the media looked on. The event received excellent television coverage by the Canadian Broadcasting Corporation (CBC) and Canadian television (CTV). Four repeater nodes were among the 18 connections made to EchoLink by ham operators in Germany, India, Canada, USA, Japan, and the UK.
