DVB-S2 and SR 22500

Postby PA1KW » Sat 29 Dec 2018 18:58

Dear all,

I've got an issue when trying to receive PI6ATV with DVB-S2 and a SR:22500. Minitiouner has a lot of noise and PLL is not locking. With normal DVB-S2 SAT receiver it works ok. DVB-S2 with lower symbol rates is working ok. Is this a known behaviour? I'm using v0.8s.
Thanks

Hello,

yes I have discovered later that with some NIMs that have too much IQ imbalance, we can have difficulties like in your case.
Version 0.8s works with all the different NIMs I own, so someone that had a problem like this send me his Nim with this problem, so
I have made a 0.8t version that fix it.

As I am working on a completely new version (0.8z actually), I have not put version 0.8t for download.
I will send it to you personally.

A new version (0.9) will be available in January 2019.

Dear Jean-Pierre,
Is there a possibility to download the 0.8t version or later?
Thanks!
