Keith Pugh, W5IU and Larry Brown, W7LB, Net Control stations for the AMSAT 20M International net have announced changes to the net operation. Keith wrote, “The AMSAT 20 Meter Net will be changing format effective 9 November 2014. It will start with check-ins at 1900 UTC on 14.282 MHz and proceed with Satellite Q&A and other topics.”
Continuing, he adds, “The weekly AMSAT Bulletin Titles will be read and an offer will be made to read or discuss specific bulletins by request. We encourage check-ins from operators who are very active on the satellites, and especially, operators that are new to the satellites and/or ham radio. The activity will generally be over by 2000 UTC. We realize that not everyone has 20 meter capability but we need more activity to continue running this net. Dust off your HF gear, put up a 20 meter dipole, and join us or let the net die a natural death.”
With heavy heart, I sadly convey, that our little angel ‘HAMSAT VO-52’ would no more be able to offer her services to the ‘Amateur Radio Fraternity. HAMSAT VO-52 succumbed in Space on 11th July 2014, while she was on her 49,675th orbit, due to the failure of on-board lithium ion batteries that have met their end of life.
Although her desires were to be at work with other systems and sub-systems working normal as per the latest telemetry received, the on-board computer recurring to ‘Reset’ mode due to the failure of batteries is preventing her to do so. Hence, it is decided not to expect any more meaningful and reliable services from HAMSAT VO-52.
Since 11th July, every best possible effort has been put in by the spacecraft controllers here in ISTRAC Bangalore to revive her back to life and to help her with work load, so she won’t be swamped when she returns, but with no luck. Though it is hard, the HAMSAT VO-52 designers and controllers insist that the time has come to let the little angel free in space to go drifting on her own from their care and custody.
Thus, today 21st July 2014, ISRO have decommissioned ‘HAMSAT-VO52’
We all here in ISRO do definitely hope that ‘HAMSAT VO-52’ worked tirelessly and was a good friend to the ‘Amateur Radio Fraternity’
around the World. We are sure that HAMSAT was loved by all who worked through her. Though, we are deeply saddened by the loss of HAMSAT VO-52, but she will never be forgotten and far from our hearts, minds and memories.
HAMSAT VO-52 will always be remembered by all of us here in ISRO as one of the greatest satellites of ours.
Dear ‘HAMSAT’, looking at the sky, we all say ‘Good Bye’ to you.
You’ll be greatly missed. Rest in Peace.
Nevertheless, at this point of time, on behalf of the World Amateur Radio Fraternity, we thank each and everyone who contributed to the great success of ‘HAMSAT’.
Particularly, our sincere thanks to the Chairman ISRO, Dr. K.
Radhakrishnan, past chairmen Dr. Kasthurirangan, Dr. G. Madhavan Nair, Director-ISAC Dr. S.K.Shiva Kumar, past ISAC Directors Dr. P.S. Goel, Dr.
Shankara, Dr. T.K. Alex, Director-ISTRAC Shri. B.S. Chandrasekhar, scientific secretary Dr. Koteshwar Rao, Project Director-Shri. J.P. Gupta, Deputy project Directors, Mission Director-Shri. R.Suresh, Operations Director-Shri. Parimalarangan and each and every person directly or in-directly contributed.
At this point of time, we also thank AMSAT-India and in particular, late Shri. Nagesh Upadhyaya-VU2NUD, Shri. B.S. Gajendra Kumar-VU2BGS, Shri.
Prathap Kumar-VU2POP, Air Commodore. Subramanian-VU2UV, Shri. V.P.
Sandlas-VU2VP, Dr.R. Ramesh-VU2RMS, Shri. Nitin-VU3TYG, Mr. Williams Leijenaar PE1RAH and each and every member.
Pasted below is the message from Mr. R. Suresh, Mission Director:
HAMSAT, the first small satellite by ISRO has been Decommissioned after nearly a decade of service to the World Ham community.
A true masterpiece among small satellites, designed for one year mission life, but exceeded all expectations by serving for almost 10 years. A truly autonomous satellite, with “Zero maintenance“ in terms of Mission operations, it provided a springboard to test many new concepts such as BMU. LI-ion based power system, automatic Spin rate control and Auto SAOC for maintaining the Satellite attitude without any ground commanding.
HAMSAT known as “OSCAR-52” among the Amateur HAM operators has been very popular because of its high sensitivity receiver and strong transmitter. Indian Radio Amateurs on many occasions conveyed to us that they have been greatly honored to share the adulations showered on ISRO and INDIA by the International Radio Amateur for gifting this wonderful satellite “HAMSAT”.
I take this opportunity to applaud the HAMSAT teams at ISAC, ISTRAC and other centre for their efforts and support, which has made ISRO proud among the HAM users across the globe.

SPROUT is a 7.1 kg microsatellite set to launch on the JAXA ALOS-2 mission on May 24th at 0305 UTC from Tanegashima Space Center, Japan to a 654km sun synchronous orbit. Watch the launch live athttp://global.jaxa.jp/projects/sat/alos2/index.html
This satellite is a project of Nihon University and will include some interesting amateur radio payloads and experiments, including CW telemetry, an FM digipeater, digitalker and message box, and live and preloaded SSTV pictures! Nihon University enjoyed previous success with SEEDS-II, aka CO-66.
