Dear Mani VU2WMY and Mr.Parimala Rangan with others,

To day 5 May 2012 VO-52 was working very well for me on orbit 37868 at 18:01 UTC.

The drift in frequency of the Beacon seems to be only less than 3 KHz upper than nominal and is reducing gradually because probably the transponder is heating up.

The SSB quality is very good with no distorsion or overloading.Worked four stations without problems.

We appreciate the timely and immediate corrective actions from ISRO and AMSAT-India.
