I have noticed that LilacSat-2's FM transponder has been on nearly
continuously for the past four days They may be keeping it active
continuously during the holiday period in China.

It's worth checking out if you haven't worked it yet. It's got a good
signal and can be easier to track than SO-50 because the carrier stays
active for a period when not receiving signals. The downlink antenna
also uses circular polarization, so there is less fading when using
linear antennas than on SO-50.

Uplink: 144.350 MHz FM (No PL)
Downlink: 437.200 MHz FM

Keep in mind that this uplink frequency is not within the normal
145.800 - 146.000 MHz satellite subband on two meters, though this
frequency is within the 144.300 - 144.500 MHz "New OSCAR subband" in
the ARRL band plan and is allocated to the Amateur Satellite Service
(as is the entirety of 144 - 146 MHz). On passes over the United
States, quite a few packet signals can be heard through the

If you use LoTW, the satellite name to use when uploading QSOs is 'CAS-3H.'
