Stephan94,with a 1.80 m Channel Master I receive today
only two frequencies (stronger in V than in H)
Just had a look here and the mux on 18669L has gone and some channel changes have occurred in 18774L. 18739L is as shown on Lyngsat.Stephan94,
You may need a piece of PTFE down the mouth of the LNB at 45 degrees to the probes to create circular polarisation. That should improve reception.

Using the linear pol feed so I'm losing 3dB, 18709 is the strongest here. I get a bit of noise from a tree on 42E further degrading the signals. How strong are these TPs with others in UK?

The levels are all over the place here at the moment and are changing rapidly between the three carriers seen on the grabs.
Here's two grabs - the Green plot is with correct LHC pol and the Red plot is with Vert Linear setting - as you can see, they don't make sense.

Here in the West of England the mux on 18709 is definitely circularly polarised and locked with 13dB C/N. The other two muxes no longer lock. They still appear to be circular and the stronger of the two is 18738. I guess they have been moved to a different beam.
