I think the signals in high band are ChinaSat 11, or maybe ShenTong-2E testing (see below).
Although there is no public frequency plan, ChinaSat-11 has transponders in both 11.45...11.7 and 12.25...12.75 GHz bands.
See for example here (Indonesian): https://www.facebook.com/group…mment_id=1194728690894571
"The Old transponder on ChinaSat 11 at 98.0°E to one is 12600 v 43200 total channel 45 and the second transponder is 12650 v 43200 as well as 45 channels. In June 2020 the second TP was off due to a disruption to my band's network."
Probably as so often there are pairs of transponders available of opposite polarisation, so 12600 both in H and V.
Since August, ChinaSat 11 has moved a bit from 98.0°E to 97.9°E.
This was to give room for the new ShenTong-2E (ChinaSat-2E), that arrived at 98.0°E (or 98.05°E) also in August.
Inclination is just 0.2°, probably In-Orbit Testing is still going on.
At 98.25°E there was already ShenTong-2A (ChinaSat-2A).
ShenTong are military satellites, presumably using Ku-band but I've never seen any signals reported from this satellite series.
It's a bit unfortunate that ShenTong satellites are also simply called ChinaSat, suggesting they are from China Satcom with commercial use, but they really are of the PLA (People's Liberation Army).
