On July 10, 2016 the amateur radio SSB/CW linear transponder on the student built satellite LilacSat-2 was successfully tested.
LilacSat-2, call sign BJ1SI, was built by students at the Harbin Institute of Technology and launched on September 19, 2015.
The 40 kHz wide SSB/CW transponder is Non-Inverting which means the Doppler shift of a signal going through the transponder will be twice that usually seen on Low Earth Orbit inverting linear transponder satellites.
Clayton Coleman W5PFG reported that he and Glenn Miller AA5PK had a contact through the transponder, a recording can be heard at

The transponder frequencies are:
• 144.3425-144.3825 MHz Uplink
• 437.180-437.220 MHz Downlink
It is not yet known when the transponder will be activated again.
