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

Hi Dinesh,
Perhaps some clarifications are in order.
The IARU has frequency coordinated SRMSAT at 437.425MHz for the down link with no mention of coordination of the uplink. The link you provided says the downlink is 434.5 MHz which puts it outside the 435-438 MHz satellite band. Additionally, it mentions an uplink at 145.8 MHz. right at the lower edge of the 145.8 to 146 MHz satellite band.
The referenced web site, www.srmsat.in, is not functional, so recent information is not available there. Do you have any other reference links?
Regards...Bill - N6GHz

Sanjay Srikanth Nekkanti, AB3OE, confirmed that SRMSAT has passed all the required tests and is now at ISRO's spaceport, Sriharikota, ready for the Oct 12th launch. The downlink and ground station details for SRMSAT can be found on AB3OE's page here: http://srmuniv.academia.edu/SSN/Papers/149827/Ground_Station_Design_for_a_Na...
At the moment, I have no information about JUGNU. Will keep you all posted as and when I get more details.
