Dear VO-52 (HAMSAT) users,

On behalf of HAMSAT VO-52 Mission Director, Operations Director and  
the entire HAMSAT Team, I take pleasure to inform the user community  

After the 'In-Orbit Maintenance Operations' the decision to turn 'ON'  
the payload transponder was taken and accordingly;

The Transponder No 2 i.e. The Dutch Transponder made by William  
Leijenaar PE1RAH would be switched 'ON' at 13:51 UT on 08.03.2012  
during orbit # 37006 over India.

A 'Critical Comparative Signal Report' between the Indian and Dutch  
transponder would be of great help for further evaluations and  
necessary actions for the maintenance the transponder in good and  
healthy condition for better services and also, the inputs would be  
very valuable to the respective transponder designers.

We all hope, Williams PE1RAH would be very happy with our decision and  
behalf of every one here in India involved with project, wish Williams  
and his transponder all the very best and good luck.

Thanks to AMSAT-India (Nitin VU3TYG) for the all the help and  
co-ordination provided.
