in vdr-1.7.28 without patches

while browsing the log I found

Jun  9 05:28:08 server vdr: [13569] frontend 1/0 timed out while tuning to
channel 1877, tp 212713
Jun  9 05:28:40 server vdr: [13569] frontend 1/0 regained lock on channel 14,
tp 110743

so frontend 1 regained a lock it never had. That seems like a consequence
of the fact that LostLock is only a local variable in cDvbTuner::Action, so it
cannot be reset when the channel changes


Looks like LostLock should also be reset in case tsSet.


also, I wonder about this code sequence in dvbdevice.c:

 switch (tunerStatus) {
...
   case tsLocked:
if (Status  FE_REINIT) {
...
else if (tunerStatus == tsLocked) {

at the else if, how could tunerStatus not be tsLocked?


In the case when the switch falls through from case tsTuned.

Bye.

 I guess that's a matter of philosophy.

fine with me - I was just wondering.

I was looking at those things because I had some trouble with my
3 USB TT S2-3600 receivers. They very often lost lock. Putting them
in a cooler place helped a bit. Better cabling helped a bit. Updating
the receiver firmware (bought in 2012, update from 2008 was not
applied!) helped a bit. Optimizing my Quad Monoblock for Astra
helped a bit. At that stage, often all 3 receivers lost lock at the
same time. And all that only with DVB-S2 channels. And mostly
in early evening (which still puzzles me)

At the end it seems the LNB had a problem.  I now have another one
and no lost locks since 12 hours.
