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

Quoting Bill Ress <[email protected]>:
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:

At the moment, I have no information about JUGNU. Will keep you all posted
as and when I get more details.
