Subject: [PATCH 10/14] V4L/DVB (4419): Turn on the Low Noise Amplifier of the Samsung tuners.
Date: Tue, 08 Aug 2006 18:06:54 -0300 [thread overview]
Message-ID: <20060808210654.PS21465100010@infradead.org> (raw)
In-Reply-To: <20060808210151.PS78629800000@infradead.org>
From: Hans Verkuil <hverkuil@xs4all.nl>
Without the LNA these tuners perform very poorly (read 'unwatchable') when
the signal is weak.
