<DIV><FONT face=Arial size=2>Hi Nick, Hartmut,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I read your posts recently on some "interesting"
behaviour of the Compro DVB-T300 with different input signal levels. I suspect I
may be having the same problem that Nick had with his external
antenna.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I have an external antenna that gives good pictures
on my analog TV, with some minor ghosting on a UHF channel around 500MHz.
</FONT><FONT face=Arial size=2>I also had good reception from a Twinhan
(Visionplus, I think) for all local channels, from 177.5 MHz to 226.5 MHz
and 536.5MHz. </FONT><FONT face=Arial size=2>The Compro with its Windows
software also works well on all channels, reporting signal strength of 85% for
some, up to 100% (at 536.5MHz).</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I'm still in the process of getting my Myth box
going properly, but I'm at the stage where I have problems with DTV
reception with the DVB-T300. Under Linux, with scan, the card picks up all
channels but the 536.5MHz. During the scan on 536.5, the "signal
quality" jumps between ~10% to ~90%, going in and out of lock. The
final result is no lock, and the signal at 536.5 is not recognized.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I think I saw this behaviour on one of the ~200MHz
channels as well, and I think it was one that reported 100% signal strength
under the windows app.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>It is making me wonder if there is something wrong
with the AGC settings for the tuner/driver? Or perhaps the signal quality or
signal level indication is being misinterpreted by the driver?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I thought about having a look at it myself, but I
can't find a data sheet for either the TD1316 or TDA10046. I presume
Philips are restricting distribution, with an NDA or similar. Do you have
datasheets Hartmut? Have you tried to get them directly from
Philips?</FONT></DIV>
