Subject: [PATCH] qt1010: Fix tuner frequency selection for 546 to 578 MHz range
Date: Tue, 20 Dec 2011 10:50:34 +0000 [thread overview]
Message-ID: <20111220105034.5150.54234.stgit@localhost> (raw)
The patch fixes frequency selection for some UHF frequencies e.g.
channel 32 (562 MHz) on the qt1010 tuner. For those in the UK,
this now means they can tune to the BBC channels (tested on a Compro
Vista T750F).
One example of problem reports of the bug this fixes can be read at
http://www.freak-search.com/de/thread/330303/linux-dvb_tuning_problem_with_some_frequencies_qt1010,_dvb
Based on an original patch by Jyrki Kuoppala <jkp@iki.fi>
