Dear friends, On behalf of the Programme Director, Mission Director, Operations Director and the entire "HAMSAT" project team, I convey their message to the Global Amateur Radio Satellite enthusiasts & users through my mail. It gives us a great pleasure to inform the World Amateur Radio community that, on 4th May 2010, HAMSAT (VO-52) is completing 5 years of successful existence in Space rendering useful and fruitful services to the Amateur radio community. We as well take this opportunity with great pleasure to inform the Global Amateur Radio community, that the overall system health and performance of "Hamsat" - "The gift from INDIA/ISRO to World of Ham Radio" is good and satisfactory. To commemorate this mile stone achievement, we have intended to bring out a 'Comprehensive Performance & Utilization Report' of the payload (Transponder) based on the user feed backs from across the Globe. In this regard, we request all the Amateur Satellite Enthusiasts and users to kindly send us their feed backs about the performance and utilization of the transponder. A detailed report expressing their views, suggestions, comments, ratings and preferably a comparison note made with other linear transponders, those already been flown and currently available one's would be greatly appreciated.

The feed backs may kindly be copied to my mail ID as well.

I have herewith attached the mail received from Operation Director, HAMSAT.

Looking forward to hear from you all.

Thanking you
