Hi Bob,
See my web page at http://kb5wia.blogspot.com for details on a
complete teardown and rebuild of a G5500 azimuth rotator; the G5400
azimuth will be similar but won't have the limit switches. There's
also a link in there for two websites that have info on rebuilds of
the elevation rotator assembly.

Hello all,
This is going to be a busy weekend for Cuba's recently founded "Grupo de

activities had been schedule so far.
* Friday night (20:30 EDT), Hector CO6CBF will be hosting a talk about
amateur radio satellite on Pico San Juan 2m repeater (145.130). The topics
will include:
- The GROS presentation in the province.
- Brief history of amateur radio satellites.
- Current operational satellites.
- Future projects.
- Types of satellites and its transmissions methods.
- Amateur radio recieving stations requirements and homebrew solutions.
- Operating practices.
- Amateur Radio Satellite operations in Cuba.
- Special Guest: Arnaldo Coro, CO2KK, Cuba's second ham in perform a
satellite QSO and Cuba's first in conduct a EME QSO.
* Saturday morning (10:00 EDT) at Camag?ey, Pavel CO7WT will be hosting a
talk at Camag?ey City Amateur Radio Club. The topics will include:
- The GROS presentation in the province.
- Brief history of amateur radio satellites and its operators.
- Basics of orbital mechanics.
- Operation methods.
- Technical requirements for set up a APRS/Beacon Packet station using the
ISS digipeater.
- Amateur Radio Satellite Fleet Status.
- Related examples.
* Saturday morning at Havana (10:00 EDT) in Cuba's National Amateur Radio
Federation (FRC). Raydel CM2ESP will be hosting the Official Presentation of
the recently founded Group. The topics will include:
- Origin and background of the Group.
- Working profile and prospects.
- Brief abstract about the Group's Rules.
- Current Board of Directors.
- Schedule of future activities and meetings.
- Questions and Answers Session.
All three events are jointly coordinated between GROS's members and each
province radio club. The events will be also in commemoration of the first
human manned spaceflight by Yuri Gagarin the April 12, 1961, the inaugural
launch of NASA?s Space Shuttle on the same day of 1981 and the celebration
of the 87th Anniversary of the founding of the International Amateur Radio
Union, IARU, the April 18, 1961.
Unfortunately in both saturday's activities we will not be able to perform a
satellite demostration because ISS and AO-27 passes are too late and SO-50
is too early instead. We are right know working on more activities
coordinations for the next week.
73,
Raydel, CM2ESP

Sorry, in previous e-mail the correct IARU foundation year is 1925 not 1961,
it was a typing mistake...

Hi Mike,
No I haven't solved my desense issue, but it really isn't an issue for me
on the LEO satellites. It was more a pain when we had Phase III birds as
their downlink signals were a lot weaker. Others with mode J desense
issues have tried putting a duplexer between the antenna and preamp and had
success removing the desense. You might try that.
I'm also including this to the Amsat-BB list because there might be others
with some idea's you can explore.

A TV profile on Elon Musk of SpaceX can be seen at
http://www.uk.amsat.org/6381
More recently Elon appeared on the Daily Show and can be seen at
http://www.thedailyshow.com/watch/tue-april-10-2012/elon-musk
Viewers in the United Kingdom will find the Dail Show appears blocked,
however, use of a proxy server can get around this problem.

Amateur Radio Newsline will mention our ARISS project on today's edition ...
HAM RADIO IN SPACE: ISS CONTACT TO HISTORIC FLABOB AIRPORT
A group of students are preparing to talk to an astronaut aboard the
International Space Station, but not from a traditional classroom setting.
According to ARISS Technical Support Volunteer Clint Bradford, K6LCS, the 10
minute live question-and-answer session will take place in hangar 16A at the
historic Flabob Airport which is the seventh oldest surviving airport in
California.
The Flabob Airport to the I-S-S contact opportunity is being coordinated by
The Tom Wathen Center's Kathy Rohm with technical support provided by K6LCS.
The contact is slated to begin at at 10:03 AM Pacific Daylight time on the
morning of April 19th and should last for about the usual 10 minutes.
More is on-line at www.iss-flabob.com

It's good to see members of the artistic community getting involved in
amateur radio.
This ARTSAT project built by students at the Tama Art University features an
FM Digi-Talker and should be launching in 2014.
