At Hamfest India (HFI) 2011, held in Kochi Dec 10-11, a presentation was given on a new Indian linear transponder and a CubeSat communications system.
This was the largest gathering of radio amateurs in India so far. Radio Amateurs and SWLs from all over the country and invited guests from other countries enjoyed the two-day event.
AMSAT-India gave several presentations at the event, among them was one by Ganesan Namachivayam KJ6LRR in which he described a satellite 435/145 MHz linear transponder with a bandwidth of 50 kHz and capable of 1-3 watts PEP output. AMSAT-India plan to develop a smaller linear transponder for CubeSats.
