I've also tested all DVB-S2 QPSK / 8PSK transponders i have on astra 19.2 and HB 13.0 and they all tune fine. I can't really tell which ones weren't working with current multiproto because i don't use most of those channels but i know for sure that ESP HD on HB13 wasn't working, and now it is.. I've simply made quick tests with szap2 so i don't know if it's stable and so on but i do get a lock pretty quickly, same as DVBS transponders... maybe other s2-3200 users can confirm thoses tests.. thx Marc Ales Jurik wrote: > Hi, > > please try attached patch.
