Dear Fellow Hams,

We are very thankful for the continuous support from you, by sending us the
beacon data. We are right now trying to estimate the performance of the
satellite and will be planning to perform the operation of the payload in
the next couple of days. Before the operation of the payload is begun, we
would like to do a small performance test with respect to the RF link. We,
therefore request you to kindly keep sending the beacon signal and also try
to send the details of the RF signal performance over the entire length of
the pass.


I would like to quote some of the words from the SRMSAT project Students and
Mentors

IT IS A GREAT MORAL BOOSTING CONTINUING INFO FLOW FROM YOU FOR THE SRMSAT
GROUP. iT MAKE US PROUD TO CONFIRM FREQUENTLY THAT OUR SAT IS WORKING. gRAET
SUPPORT.tO BE TAGGED 

We would also like to thank Mr. Nader Omer for his support by developing the
SRMVU Decoder.

 This is great. Thanks to the team for taking such efforts for developing
the decoder...its just amazing to see the response of the HAM people out
there 

Looking forward for the support.

Dear Folks,

SRMSAT a Nano Satellite from SRM University and Jugnu from IIT kanpur,
India have been successfully placed in orbit at 11:32 Am IST. I would
request the Hams all over the world to track the satellites and send in the
beacon data to the following address.

kc2...@arrl.net   and
sanjaynekka...@gmail.com

SRMSAT beacon is at  437.425 MHz
Jugnu beacon is at 437.275 MHz
 Thanking you,

Hi Bill,

The ground station paper was written before the frequencies were
coordinated by IARU. As mentioned by Mr. Mani the downlink frequency
is 437.425 Mhz.

Apparently the srmsat website is down for the past couple of months.
The web-team is trying to get the website operational.

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?
