SB SAT @ AMSAT $ANS-095.01 Recap of the Week of AMSAT-DL Earth-Venus-Earth Success

As the outstanding technical achievement attained when an inter- national team lead by AMSAT-DL completed the Earth-Venus-Earth path on March 25 continues to reverberate throughout the Amateur Radio world a recap of the event and links to additional details is in order.
The team consisted of many well known amateurs including Wolfgang Büscher, DL4YHF; Freddy de Guchteneire, ON6UG; Hermann Hagner, DK8CI; Michael Lengrüsser, DD5ER; Karl Meinzer, DJ4ZC; James Miller, G3RUH; Max Münich, DJ1CR; Hartmut Paesler, DL1YDD; and Achim Vollhardt, DH2VA.
AMSAT-DL President Peter Guelzow, DB2OS provided a report of the accomplishment from the 20 meter dish located at the IUZ Sternwarte Observatory in Bochum, Germany. The transmitter used a rubidium locked reference to generate about 6 kW CW on 2.4 GHz. The use of a magnetron for this purpose was possible thanks to a new AMSAT-DL developed modulator that enables a magnetron to be used for narrow band operation.
After traveling almost 100 million kilometers with a round trip delay of about 5 minutes, the transmitted signal was clearly received as echoes from the surface of Venus. FFT analysis software with an inte- gration time of 5 minutes was used. After integrating for only 2 min- utes the reflected signals were clearly visible in the display. Despite the bad weather, signals from Venus could be detected from 1038 UTC on until the planet reached the local horizon.
Receiving planetary echoes is a first in Germany and Europe. This also marks the farthest distance attained by radio amateurs. The dis- tance via the Earth-Venus-Earth path is over 100 times further than the echoes from the moon via EME reflexions.
The official Press Release: "First German Mars Mission makes sidestep to Venus" can be downloaded as .PDF here: http://www.amsat-dl.org/pic/gallery2/main.php?g2_view=core.DownloadItem&... temId=7561 (careful with line wrap!)

Jess, W4MVB expressed the admiration of Amateur Radio operators around the world in his message, "Congratulations to you and your team for this outstanding accomplishment! I simply can't believe how far we have come since I first heard OSCAR 1 & 2 transmitting "HI" from space. I feel privileged to be a witness to the kind of success our hobby has experi- enced thanks to you and all the dedicated amateurs around the world who have brought us to this point."

AMSAT News Service Bulletin 095.03
From AMSAT HQ SILVER SPRING, MD.
April 5, 2009 To All RADIO AMATEURS BID: $ANS-095.03
AMSAT received the sad news this week that satellite operator Mak, SV1BSX became a Silent Key. John, LA2QAA and Al, GM1SXX noted that, "The entire Amateur Satellite fraternity and in particular EU-AMSAT suffered a great loss".
Mak was a founding member of EU-Amsat together with LA2QAA and GM1SXX, a group dedicated to Amateur Radio Satellite enthusiasts. Mak created the AO-7 DX list and was an avid AO-7 operator.
LA2QAA recalls Mak worked very many people on 'The old Girl' (AO-7) giving many operators their first AO-7 contact with Greece. He con- tinued, "It is both appropriate and fitting that so many operators offered their condolences on the AMSAT-BB for the very sad loss of my dear friend Mak SV1BSX. He was an inspiration to many newcomers to the satellite scene and his web pages will remain a source of ins- piration to future potential Amateur satellite operators."
Nader, ST2NH - Rest in peace my Elemer Mak SV1BSX. We well miss you the on air and on the list. My condolences goes to all EU-AMSAT, AMSAT-BB lists members and to his family. God bless your soul.
Terry, G1WPR - I'm very sad to hear the bad news about Mak, it was always a pleasure to say hi to him via the sat's. He will be sadly missed, goodby my friend.
Frank, IW4DVZ - I have no words ... to talk with him was, like ever, a pleasure. My condolences to his family, rest in peace my friend.
Joe, K3SZH - Mak made his last entry in the AO-7 Logger on March 14, 2009 with 2109 QSOs. He will be missed by all of us. The AO-7 group salutes you with our antennas pointed straight up.

+ The status of New Zealand's AMSAT-ZL - KiwiSat - has just been updated. Check out their steady march to a launch at: http://kiwisat.org/index.html
+ Congratulations to Mike Fincke KE5AIT! He now holds the record for the most ARISS contacts on a single expedition as well as the most for multiple missions. Expedition 18 has now set the record for ARISS contacts by an expedition. Total number of ARISS ISS to earth school contacts is 426. Total number of ARISS supported terrestrial contacts is 22.
+ With 660 stations using the AO-7 logger worldwide 24 stations have made the 1000 plus list of QSOs. Five of those stations eclipsed the the 2000 mark: AJ9K Dan - 2001 QSO; N3TE Steve - 2045 QSO; 9A2SB Zlatko - 2103 QSO; OH8MBN Mika - 3000 QSO. Visit the AO-7 log page at http://www.planetemily.com/ao7/ao7log.php (via K3SZH)
+ LU2DPW now holds the first and second place standing for distance via AO-7. A CW contact between W4FDU and LU2DPW attained first place with 7537 KM. A contact between AA4FL and LU2DPW is in second place with 7524 KM. K3SZH and PY4AJ hold third place with 7438 KM.
+ PCSAT-1 (NO-44) orbit was in a full sun period until March 30. Control Station DK3WN notes that despite efforts to activate PCSAT it does not remain on for an entire pass due to unfavor- able illumination angles on the solar cells. PCSAT is only available during daylight passes on 145.825 MHz packet.
+ Iridium announced the company completed the replacement of the operational Iridium satellite lost in the collision three weeks ago with a non-operational Russian satellite on March 4. (via SpaceDaily Express)
+ The American and Russian pair set to take over the International Space Station (ISS) will be the first part of the doubling of its permanent crew. The launch from the Baikonur cosmodrome, Michael Barratt and Gennady Padalka, said their mission marked a new phase in the history of the ISS as the permanent crew is to be enlarged from three to six in May.
