42.0°E Türksat 5B

I tried to use the one on the right with LO 11.8 GHz but got no signal. Instead, I got in / repeated frequencies below.
I wonder if the extension signal is that weak in my area(?), because in Ku-band, I have almost a DTH signal on Turksat at 42.0E.

I have to keep trying.

I think that there are big problems with the BWEI LNBs on Ext KU. They appear to have very poor image rejection which gives the effect you see. It is especially bad on 42E due to the strong signals below 12.75GHz. I don't think they have much RF filtering. There is also the problem of unwanted sampling modes in TBS and other cards.

One way to check if you are 'seeing' an image is to look at the Spectrum box on CS which usually shows 'Inverted' on most signals. If it shows as non-inverted, it's likely to be an image response.

My modified SMW is a 12.25-12.75GHz PLL which had an LO of 11.3GHz. I have changed the LO to 11.75GHz and tried to improve the performance on ext Ku. However although the NF is 2dB, the gain is 20dB down compared to its response at 12GHz. I use a 1.5GHz high pass filter followed by an 18dB gain amplifier in the IF. I still see an increase in noise when pointing at the strongest satellites and this is probably caused by front end overload.

Nothing from 13497 H 13330 on 1.2m from my place - only carreir on 13526 H is visible here...

/edit: Sorry guys... it´s my vertical spectrum here!

Okay... sorry about my last scan above, it was from vertical spectrum... but now, I´ve changed in horizontal spectrum (it seems)...probably a more exactly skew is needed for a better signal... scan with 1.2m KATHREIN Offset antenna...

I optimized LNB skew for horizontal range

Now I reach about 6.0dB over LM on my 1.2m dish from my pace on TC at:
13497 H 13330 3/4 DVB-S

PS: I´m using CS tool for showing correct polarisation here.

Good signal for my 1.2m in the early evening hours... about 7.5dB over LM on:
13497 H 13330 3/4 DVB-S

13497 H and peak on 13526 H have left...

Wenn das Spektrum auch noch dazu passt, ist die Welt für mich wieder in Ordnung

Just a look in year 2025... nothing appeared in horizontal extended range...
