First time I can see here something like a feed transmission. TC at scan time. Without PMT.
PS: This is a circular frequency, so ignore my linear signal here. Probably someone else can check polarity...?
3673 R 4000 2/3 DVB-S2 8PSK
/edit: Signal has left a few minutes later again.
/edit2: confirming this signal in circular right by jaes (alias John on satellites.co.uk)
