Hello Domenico, Not attempted during 01:44 UT pass. Probably the command station may give a try during the next pass at 03:20 UT. Not received any updates from them yet. Will keep you all informed with the ongoing developments. 73 de Mani VU2WMY ------------------------------------------------------------------------------ Hi Mani, VU2WMY I would like to know from you if the attempt to switch ON the Dutch transponder on VO-52 at 01:44 UTC, March 14 2012 was succesfull or not.

G5500 Azimuth Rotator Update
by David Palmer KB5WIA 13 Mar '12

13 Mar '12

Hi Everyone, Here's a quick update on my G5500 Azimuth rotator story. (Recall that three weeks ago I stalled the rotator after switching antennas.) Yaesu Parts USA is still backordered on the replacement motors, possibly some will arrive from Japan in a few more weeks (or possibly not). The company that I sent the motor to in LA (Eurton Electric) just gave me a quote today for the rewinding cost: $365. That's close to $3X what the motors go for new (if you can find one!), so at least with them it's not cost-effective to repair the motor. I'm having the motor shipped back, and I'll either try to rewind it myself, maybe someone else who can rewind it, or buy a replacement sometime in the future. To get the antennas back on the air, I decided last week that it would be good to have a spare -- so I ended up purchasing a replacement G5500 system and installing the azimuth rotator this last weekend. Everything's working great so far! I also added a thermal cut-out switch to the motor to prevent a similar stall-induced-motor-burnout in the future. If anyone is interested in how I installed the switch (or what a G5500 azimuth rotator looks like inside), I've added pictures to my blog at: http://kb5wia.blogspot.com/2012/03/az-el-antenna-system-new-70cm-yagi-and.h… 73!

VO52 not heard @ 0245 UTC pass
by Patrick STODDARD (WD9EWK/VA7EWK) 13 Mar '12

13 Mar '12

Hi! I was outside for the 0245 UTC VO52 pass here in central Arizona (DM43), and heard nothing from the transponder or the CW beacon. That was a 74-degree pass here, which should have been easy to copy. 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/

Due to 'Operational Constraints' the commands to turn on the transponder were not been able to send. In-convenience caused is regretted. The next attempt would be made during 01:44 UT pass over India.

UPDATED AMATEUR SATELLITE FREQUENCY COORDINATION REQUEST
by Hans 13 Mar '12

13 Mar '12

Frequency coordination for amateur radio satellites is provided by the IARU through its Satellite Advisor, an official appointed by the IARU Administrative Council, its top policymaking body. The IARU Satellite Advisor is assisted by an Advisory Panel of qualified amateurs from all three IARU Regions. The panel meets regularly via Skype to consider amateur satellite frequency coordination requests for satellites planned for operation on frequencies in the amateur service. The panel members often provide advice and assist satellite builders with the selection of the best possible frequencies to meet the objectives of their mission. The Amateur Satellite Frequency Coordination request form has been updated (Version 27) and is available for download from www.iaru.org/satellite. On the IARU web satellite page there are also available a number of guideline documents which will assist satellite builders, including a document on the ITU requirements for Amateur Radio Satellites. . 73 Hans ZS6AKV Hans van de Groenendaal IARU Satellite Advisor

by Mark L. Hammond 13 Mar '12

13 Mar '12

Hi All, I am going to host an AMSAT table at the RARSFEST in Raleigh, NC on Saturday, April 7th (yes, Easter weekend). Anybody care to assist? We usually can't pull off demos, but hosting a table with toys+tracking programs usually draws some good attention and publicity. The RARS folks always make us feel welcome. Please contact me directly if you're willing and able to help. Thanks! -- Mark L. Hammond [N8MH]
