Hi Bill and Dinesh,

I was a part of the ISRO team that conducted the Thermal Vacuum,  
vibration and other environmental tests for both Jugnu and SRMSat.

I was able to receive the signals from both the satellites, while they  
were here in my cetre during the above mentioned test. I even used  
Funcube Dongle to receive and decode the telemetry CW data.


SRMSat: Payload down link and CW Beacon on the same frequency -  
437.425 (10dbm)
Jugnu:  CW Beacon - 437.275 (17dbm)
         Pay load  - 437.505
