Amsat India members were invited for the User Meet on 9 April 2005 organised by ISRO.

The meet was presided by the top management of ISRO, Chairman Mr Madhavan Nair, Director Mr Goel, Program Director Mr Thygarajan, Project Director Mr J P Gupta , along with most Divn heads with respective scientists and hams of ISRO were present.

[use LESS than 100w ERP - ERP is TX power times Antenna Gain - M5AKA]
AMSAT INDIA will keep you the updated of orbit data after the launch once a week or as and when major changes are effected.

About 20 of ham sat user community here attended the meet which was very interesting, interactive and got to visit the clean room to have a good look at the Sat just before being packed to the launch site.

VU2UV Air Cmde Subramaniam, President of Amsat India presided on behalf the Sat users ( himself being a very old timer since the early OSCAR operations ) A power point present highlighted the Sat users from early Oscar days till
the present day Sat commuincations.
ISRO wished to see the complete ham built transponder for the future series of HAMSAT, from where we left last time and for which work is in progress by Amsat India regd.

Another User meet is scheduled for May 2005 and those having any inputs for the same, maybe sent to VU2RMS, VU2POP, VU2UV, VU2WMY.

Wishing HAMSAT all the success and hoping to work a lot of DX.
