Raydel,

look here:
https://www.itu.int/online/snl/satbandold_snl.sh?ntc_id=117545331&fr1=8400&fr2=8500&ie=y&sat_type=&sat_name=LUNAR+CTDRS-1&sel_satname=LUNAR+CTDRS-1&plan_id=

It is one Xband emission and several Sband. 2234.52 MHz seems to be
always on, others intermittently. Never saw anything on Xband.

Cheers
Edgar
