[linux-dvb] TT S2-3200 driver

[ChaosMedia > WebDev]

Hi,

just tried your patch and it seems to have its effect, i was able to 
tune to HB 13.0 11278.36 V DVB-S2 (8PSK) - 27500 2/3 - Eurosport HD 
which i wasn't able to tune before.

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
