Call it Birthday Luck???????
on 5th May, 2010 - the 5th Birthday of our beloved satellite - HAMSAT - VO52, we were lucky to have an overhead pass @ 2113 IST - 85 deg peak elevation.
My VHF Moxon has become a inverted vee MOXON :( Birds sitting on the horizontal elements have bent the elements downwards when the fly off. I have not been able to bring down the antenna and rectify it. In this situation, the only hope of working the satellite was with rubberducky from the roof. Luckily, it was a clear - non rainy - evening .
Up on the terrace, (I am lucky to have a near - clear visibility allround) I gave it a shout - and I had a 59+ report QSO with VU2GUR and later on I got reports that I was going through 59 to VU2DPE and VU3STJ.
Thank you HAMSAT - for giving me a real memorable experience on your BIRTHDAY - goes to show no sophesticated setup is really required to work the BIRDS.

HAPPY BIRTHDAY - HAMSAT - VO-52
HAMSAT- VO-52 Celebrates 5th Successful year in Space - AND GOING STRONG
Heres Wishing one of the Most Popular and Successful of the OSCARs - HAMSAT - VO-52 - The PRIDE of INDIAN HAMS - A VERY HAPPY BIRTHDAY - In Space.
During the last one year, since I started working the OSCARs - I have had many successful QSO through the HAMSAT and found that the signals are more stable and accessible compared to other Sats at the same angle of elevation.
I am sure that this Bird will have many more years of successful and active passes.
KEEP FLYING - HAMSAT
I thank all those who were part of the planning, testing, integration, launch and operation of the HAMSAT. Special thanks to AMSAT-INDIA and ISRO for taking up this cause that has put INDIA on the OSCAR Map.
Eagerly awaitng the HAMSAT - II

HAMSAT Transponder Performance and Utilization
May 5th 2010 is a red letter day for Indian Ham Radio Operators, especially those who are working through OSCARs - the 5th Anniversay of the Indian OSCAR - HAMSAT - VO52.
In this regard the Operations Director of HAMSAT is seeking details on the useage, utility and experiences of HAMS using the HAMSAT. The email request is reproduced below. Please share your experiences with all of us - so that we can compile a database of the users of VO-52 and their personal experiences. This should go a long way in an early launch of HAMSAT-II.
Respond directly to VU2WMY or to this blog so that we can compile the responses at an early date and forward to the HAMSAT team.

Dear friends,
On behalf of the Programme Director, Mission Director, Operations Director and the entire "HAMSAT" project team, I convey their message to the Global Amateur Radio Satellite enthusiasts & users through my mail.
It gives us a great pleasure to inform the World Amateur Radio community that, on 4th May 2010, HAMSAT (VO-52) is completing 5 years of successful existence in Space rendering useful and fruitful services to the Amateur radio community.
We as well take this opportunity with great pleasure to inform the Global Amateur Radio community, that the overall system health and performance of "Hamsat" - "The gift from INDIA/ISRO to World of Ham Radio" is good and satisfactory.
To commemorate this mile stone achievement, we have intended to bring out a 'Comprehensive Performance & Utilization Report' of the payload (Transponder) based on the user feed backs from across the Globe. In this regard, we request all the Amateur Satellite Enthusiasts and users to kindly send us their feed backs about the performance and utilization of the transponder. A detailed report expressing their views, suggestions, comments, ratings and preferably a comparison note made with other linear transponders, those already been flown and currently available one's would be greatly appreciated.
The feed backs may kindly be copied to my mail ID as well.
I have herewith attached the mail received from Operation Director, HAMSAT.
Looking forward to hear from you all.
Thanking you

DEAR MR. SUBRAMANAI,
This is to bring to your kind attention that HAMSAT is COMPLETING 5 YEARS of successful existence in space. I am sure, HAMSAT continues to be the DARLING of the HAM Community.
To commemorate this event, ISTRAC is bringing out a "5-YEARS OF HAMSAT PERFORMANCE" Report. To make the report a comprehensive one, we would like to add the FOLLOWING INFORMATION.
1 PERFORMANCE of the HAMSAT TRANSPONDER as _perceived by the users_
2 COMPARISON of the HAMSAT Transponder with her CONTEMPORARIES
3 Details of SATELLITES providing SIMILAR SERVICES
4 Approximate NUMBER OF USERS of HAMSAT in _India / over the globe_
5 GROWTH of HAMSAT USERS, since launch
6 Approximate HAMSAT TRANSPONDER UTILISATION (transponder interaction period) over the globe (transponder is ON always)
7 Any more INTERESTING INFORMATION on HAMSAT
KINDLY _DO THE NEEDFUL_ BY CIRCULATING THIS REQUEST TO OUR HAM FRIENDS.
With Best Regards,
T.PARIMALARANGAN

Satellite Activity - VO-52 - 28nd Feb, 10 - evening
VO-52 evening Pass @ 2145 IST was a rather unsuccessful experience as generally it was found that the downlink side was rather noisy today.
In-spite of this, the other stations heard on the VO-52 today were VU2GUR, VU2GZ, VU2ZUB, VU2SWG were heard independent of each station i.e, most stations heard most of the other stations - BUT NO 2-WAY QSO REPORTED. I heard VU2GPS for only one call and then nothing heard.
Surprising phenomenon. Better luck tomorrow.

Welcome to the OSCARs - Amateur Satellites
Based on the advice of a few Hams, I decided to start this Blog so that I can share my experiences along with some backgroud of the Amateur Satellites - OSCARs - Orbitting Satellite Carrying Amateur Radio.
For Basic information, I decided to check up on the history of OSCAR. To my surprise, I discovered, that the first OSCAR was launched as early as 1961 - December 21st to be exact. That is just over 48 Years ago. We should be celebrating 50 years of OSCARs next year !!!!!
The first OSCAR was put into an elliptical orbit just about 150Kms going up to about 300 Kms (due to the elliptical Orbit) from the Earth's surface, just above the Earth's atmospheric layer. - This was OSCAR-1. It had a beacon on 144.983 MHz transmitting HI on Morse Code. The Tx power was 140mW from the satellite measuring 9in.x12in.x6in Tall. It lasted for all of 22 days on the air and 50 days in space before it lost altitude and burned up on entry into the atmosphere on Jan 31st 1962.

OSCAR - 1This was/is just the beginning.
I will also post details on the basic necessitites, equipment requirements, operating procedures, etc. I also welcome questions either as comments on the blog or via direct email to vu2mud@gmail.com. Let us learn more about this interesting operation as we go along.
