Mineo Wakita JE9PEL reports on his website that Beijing may launch satellites carrying amateur radio payloads in July 2015. It is understood the launch would be on a CZ-6 rocket from the Taiyuan Satellite Launch Center.
XW-2 (CAS-2) and LilacSat-2 will be carrying amateur radio payloads but at the time of writing it is not clear if Tiantuo-3 and ZDPS-2 may also have amateur radio payloads.
Additionally it is reported elsewhere there may be up to 20 satellites on the launch.
