Mani VU2WMY provides this update:

Dear HAMSAT VO-52 users,

With regrets, we confirm the non-availability of the transponder on HAMSAT VO-52 since 28th February 2012. This is the first ever interruption in the services of HAMSAT since 5th May 2005.

The timely feed back from John K8YSE, Domenico I8CVS, Eugenio IZ8JHD, Jan PE0SAT and Nitin VU3TYG were highly appreciated and acknowledged by the ISRO’s HAMSAT Mission Management Board.

I’m herewith enclosing the mail received from Mr. T.Parimalarangan, Operations Director-HAMSAT VO-52 regarding the ‘Temporary Non-availability’ of VO-52 transponder and beacon.
Mr. Subramani VU2WMY:

Thanks for obtaining the user feedback. You may please post the following message in the Users website. If possible, try to find out who has last operated HAMSAT payload transponder on 28th and at what time

“HAMSAT Transponder services not available temporarily due to operational reasons. Inconvenience regretted”
