My Satellite Setup
1.5m IRTE PF, Octagon OSLO external Ref., TBS6983,
Various L, S, C, X & Ka bits. 1.2m S/X/Ku/Ka Prodelin on Az-El
My Location
SE UK
My kit only goes down to about 17.6GHz and is linear polarised. I use Norsat 9000HX-03b-BN and modified Gilat band B LNBs on a 1.2m Prodelin. So far the only things I have found are the beacons on Mentor 4 (44.1E incl)

124963

& Mentor 6 (52.8E incl).

124964

Both the above are very strong and can easily be seen using Crazyscan. The transponders on these satellites seem to have very wide band spread spectrum and cover about 18.1-19.9GHz.

There are data TPs on the Band E MENA transponder on Es'hail 1 (25.5E) centred on about 17.765GHz. They are about 200MHz wide. Since I was using a linear feed, I'm not sure if there are one or 2 signals (one on each pol?). They can't be seen at all on Crazyscan and are way below the level needed to lock. (Thanks @hvdh for identifying the source)

They are very nice sharp spectra in the first two pictures.
If they are software generated can you share what software it is, the style looks familiar?

Looks like SDR Sharp to me.

Yes, SDR# and an Airspy R2. All the above plots were captured whilst using the modified Gilat band B LNB. Here's the full GUI
