	The Hindu : Opinion / News Analysis : Small satellites making it big (Site not responding. Last check: 2007-10-26)
		It was Hamsat, a microsatellite built by the Indian Space Research Organisation with the help of amateur radio operators (known as hams) in India and in the Netherlands.
		Hamsat was built in two years at a cost of just Rs.3 crores, according to K. Thyagarajan, who heads the small satellite programme at the ISRO Satellite Centre in Bangalore.
		Hamsat has already become the most popular amateur radio satellite among Indian and foreign hams as it relays voice signals rather than the more sophisticated digital communications, says Pratap Kumar, secretary of AMSAT India.

		The uplink of HAMSAT is in RHCP, opposite of the 2m downlink that is in LHCP.
		When HAMSAT is released for ham use, the ISRO will open a webpage and publish the actual data and keplers.
		I hope HAMSAT will work okay and for long time, so it can be in service for the world-wide ham community.
