Dear VO-52 (HAMSAT) users,

Subsequent to the clearance by the 'Expert committee' the Transponder  
# 2 (The Dutch Transponder made by William Leijenaar PE1RAH) on board  
HAMSAT V0-52 would be switched 'ON' at 13:42 UT on 13.03.2012 during  
orbit # 37080 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, once again all the very best and good luck.

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