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 The URL is www users zetnet co uk/clivew/
