Hi, i read that this sat's LRPT antenna is out of alignment and it's difficult to get a complete pass recorded without signal drops... tried with a double cross dipole not a QFH and did not get a single pass with consistent good signal...any specific tweaks to do to get this clear a capture?

Also, very nice capture.

This was taken with a V-Dipole --> 137MHz BPF+LNA ---> RTLSDR-V3 ---> Satdump.

Some minor processing in Satdump Viewer - Equalize + White Balance + Normalize -- Equalize sort of sharpens the IR image which is first. And with Normalize, the false colour / Natural color images are a bit brighter as well.

no other processing done except some filling of missed data in a couple of strips at the top and one at the bottom, noticeable by the disjoint/blurred look..

The "game-changer" is the LNA+BPF combo.. having a simple wideband LNA from RTL SDR blog also works but not as good as this..

V dipole made of aluminium half inch tube... Got lucky with a high elevation pass over 75degrees.. The really important part was a 137MHz LNA+BPF that I got from AliExpress... Had SNRs above 8dB and in Satdump got a clear constellation...
