18.633 is also present but very very low.
All the 5 frequencies previously detected by Feedsat_DXer in 2018, were used for data. Info lifted from Satellitescommunity.de thankyou.

.. The low level signal at 18.608 not resolved yet per 's-band' screen grab, so needs checking out - perhaps stronger signal in Europe ?.

Can anyone else confirm the data signals from Thor 7 0.65W from 18.6-19.6GHz? Most are LHCP but there are some on RHCP and they are <3MHz wide. They peak at the same point as the beacon on 20198MHz. In teh 2nd plot, red=LH, green=RH.

Scan on Thor 7 @ 0.6°W on that frequency span produced diddly squat Graham - not even the slightest hint of a signal over the whole 18GHz band. Limited to scan polarities though - could only do a Vertical scan on the Norsat PLL and a LHC scan on the Hughes.
**Edit - i did scan either side of the Thor 7 orbital position and still diddly squat. My analyser display was as flat as a pancake , nothing like your trace.
** Double edit - - iv'e scanned from 19° East from where Newsnet is etc through to 15° West on the 18GHz band on V pol and there is nothing here at all once you leave 19°E, will try on the LHC Hughes.
** Treble edit - same result on LHC scan from 19°E through to 15°W - - nothing.

Here's RHCP and which shows the data in comparison to the GS etc. The data is only 3-4dB over noise maximum and that is with a video BW of 20-30Hz. The sweeps are 4096 points hence the large plots.

I'm wondering if it's a footprint coverage thing with me Graham ?? as i live half way up the UK and seeing nothing - you are down at the bottom of the UK and dreamsat1 is even further south and better covered by the Ka footprint ?.

From my QTH, nothing in Ka band A whatever the polarizatino
and I obtain a different KA Band B scan Result .

This is what Band A looks like. Nothing to do. RHCP
Thanks, it looks like you are seeing something, maybe a little stronger than me. i don't think there's much we can get from those signals, even if they were strong.

CS doesn't see any of the weak signals here. Unless it disappeared between your scan and mine, the only one of yours I can not see is 20110.
Thor 7 0.65W RHCP below:

Here's my scan of Hylas 4 33.5W LHCP

The lower 2 are AOL. There is activity in both polarisations into Band A but nothing resolvable using DVB tools.
