technotrend S2-3200 symbol rates below 5Msymbol/s not supported/working - vdr

7 Jan 2018


      hey folks, i'm having some trouble with technotrend s2-3200 dvb-s card [ https://www.linuxtv.org/wiki/index.php/TechnoTrend_TT-budget_S2-3200%C2%A0%5... is being recognized:05:04.0 Multimedia controller: Philips Semiconductors SAA7146 (rev 01)
        Subsystem: Technotrend Systemtechnik GmbH S2-3200
        Flags: bus master, medium devsel, latency 32, IRQ 20
        Memory at fdcfe000 (32-bit, non-prefetchable) [size=512]
        Kernel driver in use: budget_ci dvb
        Kernel modules: budget_ciMy Kernel: 4.14.11-1-ARCH.It works fine with w_scan or tvheadend I can watch many stations on multiple satelites without any problems, however when trying to tune anything with a symbol rate lower then 5000 (5 Msymbols/s) the driver does not seem to support it, see below messages from w_scan when trying. This makes me miss many stations I'd like to receive.
However, the manufacturer clearly indicates the card supports symbol rates starting as low as 2000 (2 Msymbols/s), [ http://www.tt-downloads.de/Update/engl/techspec_tt-budget_s2-3200_en.pdf%C2%... the driver needs to be adjusted I guess? How can I make it work or adjust the driver for this?trying 'S2 f = 12138 kHz H SR = 14580  2/3 0,AUTO  8PSK  (0:0:0)'
