I was talking about the coaxial cable between FT818 and transverter. Double check the cable or adapters if there are any. Difficult to damage the internal attenuator with only (maximum) six watts. So it is very likely that the problem is the coaxial cable or any adapters.
a trivial question:
there is a cable between your FT818 and the transverter.
Is the cable ok?
Or, you've probably sent too much power to the input (432 MHz) of the transverter damaging the internal attenuator.
One of the two hypotheses is the right one.
To be clear, this "new transponder" is on ASTRA at 28,8°E and not from Eshail2.
If your antenna is not optimal pointing to 25,5E or has a wide beam (small dish), it may have some influence..
I have an SDR and unmodified PLL-LNB, fortunately not a glimpse of the stripes you are seeing.
In fact, any transponder on Eshail2 could never cause interference in Northern Europe since ALL Eshail transponders transmit on a mena beam. I receive with 100 cm Dish, unmodified Octagon Twin LNB OL 9750, RTL-SDR V3
No interference before or after switching on this phantom transponder.
On the frequency of 11976 V (Badr 4 @ 26 ° E) I receive this transponder without any interference on NB QO-100.
The problem was also discussed on Twitter. I think that the new transponder is not the cause of these interferences but the proximity of an LTE BTS in your vicinity. Note that not everyone has these interferences and this should be a clear indication. Some LNBs already have an LTE filter, others obviously don't have this filter. With a LTE filter of a few euros placed between the output of the LNB and the SDR dongle solves the problem.
I use an Octagon Twin OTLSO without any interference problem
No filters added, no problems.
they are two different aspects. Some commercial satellite TV receivers leave the LNB always powered because even in standby mode they receive from the provider a new channel list, a new firmware etc. In any case, not for reasons of stability. A few kHz drift does not affect the reception of TV channels.
For our use, leaving the LNB always powered is aimed at system stability. Yes, in our case it is certainly useful to leave the LNB always powered.
It appears that a SSTV store and forward system is active on the ISS. I wrote something on Twitter but I didn't get an answer.
A few days ago I left a system to automatically receive SSTV signals from the ISS.
During the Inter-MAI-75 activity the signal was modulated with low index and the image quality was poor.
With the second event dedicated to W5LFL, the transmissions are good again with excellent images received.
Here the surprise; together with the images of the event I also received images that were not related to the commemoration. In doing an Internet search, I discovered this supposed Store and forward system. Has anyone received strange images like this from the ISS?
I would like to add some links to those reported by Peter, DB2OS.

These are my last blocks received yesterday before the impact of DSLWP-B on the moon. A block of JT4G and a GMSK frame. For a number of reasons it was the most complicated day with DSLWP-B. Problems with the preamplifier, problems with the mobile Internet connection, problems with the new SDR dongle. Everything seemed to be going wrong but still happy to have received the satellite before the end. It was a beautiful adventure that I could only follow from the holiday home by the sea. In the city we have so many of those signals, so many of those interconnected repeaters, all over the UHF spectrum. A sewer of RF.
Hi Holger, thanks for the tip.
I have installed the app on all my Android devices.
25.9 or 26 is the same thing for our antennas.
Seeing is believing.
WB beacon passed first at 5000 SR, then at 3500 and then disappeared.
I'm interested but this message appear when I'm trying to browse :

I'm using the same version (B iI suppose but where is the evidence ?), still having issues with Mititioune express HW. I'm fighting a lot to have a best results, I can decode only down to 1 M/s, below it's impossibile. I downloaded the version :
73 vy best
Alessio, rev B does not require HW modifications.
Page 29 manual.
Alessio, which version do you have the A or the B?
I have the B and I have no problem even with weak signals.
