The band 4400...4500 MHz is for fixed & mobile (military) only.
A satellite using this band would be, at least, very sercretive...
Extended C-band for satellite is 4500...4800 MHz.
(Fixed & mobile military also uses this band)
So I think you get these signals from a sidelobe...
If your dish farm has a few spares, you could scan the horizon for the direction of such earthly signals.
Edit: And the spikey stuff in the band 4200...4400 MHz, could be radio altimeters aboard aircraft.

Thanks hvdh for your help.
I thought first, about Spainsat but no Cband .
Sorry Feedsat, I can´t find this spectrum here.
OK, this report confirm hvdh's informations.
danke
finally this signal is still there, I will never know what is it exactly.
Tried again, but nothing to find in spectrum here...
A quick look at this position and the signal is stilll there and strong
probably a local signal.
My circular left spectrum.
Just my (circular) spectrum.
