I'm not sure what happened to my tuner could be called transitory. As I <br>
recall,over a few days, recordings on one channel in particular had lots <br>
of errors, getting increasingly worse to the point of total failure (0 <br>
byte recordings). When I used the HDHR config gui, I could see the SS/SQ <br>
numbers were way down, and when I compared a channel scan using:<br>
hdhomerun_config ${device} scan ${tuner} tuner${tuner}-scan.out<br>
to one done months earlier, I could see SS/SQ changes to other channels <br>
as well. So the problems persisted for at least 48 hours until I power <br>
cycled and SS/SQ were restored to the months earlier levels. Not what <br>
I'd call transient. Or am I missing something?<br>
<br>
If it still sounds like LTE interference, what are your thoughts on <br>
brand names for LTE filters? I see channel master has one for $25 and <br>
Philips has one for < $10. Both are 5G LTE filters.<br></blockquote><div><br></div><div class="gmail_default" style="font-family:monospace,monospace">I have a Channel Master amplifier / splitter (cannot speak to an interference reducer), but it is a top quality product - just speaking to the manufacturer's quality.</div><div class="gmail_default" style="font-family:monospace,monospace"><br></div><div class="gmail_default" style="font-family:monospace,monospace">-Greg</div></div></div>
