Dear HAMSAT VO-52 users, As you all are aware that HAMSAT VO-52 is completing 8 years of fruitful services in orbit on 5th May 2013. As usual, an 'Annual Performance Report' needs to be prepared and submitted to the HAMSAT Mission Management Board at the earliest.

In this connection, I'm herewith forwarding the mail received from HAMSAT Operations Director requesting for the 'User Reports' on the performance of the transponder.

Hence, on behalf of HAMSAT Operations Director, I request HAMSAT VO-52 users to kindly send us your valuable feed back/comments/suggestions on the performance of the transponder and the same shall be mailed directly to: tprangan@istrac.org and copied to: wmy@isac.gov.in

NOTE: We also look forward for suggestions and proposal for future transponders and orbit preferred for possible next HAMSAT from India.
