That's strange, for me it doesn't work in SF8008(si2166). Or any silabs.

But it most likely works in every box with avl6261. SF8008 Supreme and Gigablue Trio PRO tested and working.

Edision 4K (mio, mio+ and mini) needs driver mod also.

Also working in VU+ Uno 4K (likely all VU+ 4K models except Zero). But different enigma2 patch is needed.
 
I need to verify my enigma2, but No Signal below lock so far with my SF8008 Supreme. I need to double-check the enigma2 though and make sure your changes are in it.

I did the tests on SF8008 with a test image that Captain from OpenATV provided me with.

Is there new drivers in that image? Or value just converted from signal strength? Signal strength is available in silabs, but it's useless, you need real SNR
 
Captain only built the OpenATV7.4 with your patches, once for the Mio4k and for the old SF8008.
 
Btw here are enigma2 changes I have been using for Supreme and GBtrio Pro. There is one change more compared to os mio patch.

Also it should be improved little, read_snr function returns very high/negative value "555.4" if there is no signal, this value should be ignored.

I cannot get signal below lock to show on my Supreme. Enigma2 distros are different. Can you attach the modified enigma2 files (frontend.cpp & frontendparms.cpp)?

Thanks.
 
Attached these files, but they are only for OpenVix image.

You can also use simple python script to show snr in terminal. See attached snr.py. Copy file to tmp folder. Open signalfinder and some frequency. Open terminal and run "python /tmp/snr.py"

@suedschwede were these private images? I would love to get the Osmio 4K one. Perhaps I should ask him myself about HD51 as well.
 
Fixed my mistake in applying the enigma2 patch for OpenPLi build. Now my SF8008 Supreme shows signal below lock. Thanks ocean04!

Is AGC same as signal strength? Signal strength is also available, but I'm not sure how useful that is. Seems that signal strength always has some value even when there is no real signal.
 
you are right but with motorised mount AGC(signal strenght) is useful .
between 0% and 50% AGC is not useful but between 60% and 100% it s become good.
do you know how to send every second these informations ?

I am not talking about a driver change, but an Enigma2 code change in their .bb that will allow any tuner that supports SNR below lock can benefit from. Other drivers/tuners that do not support it will simply not show it. I find it high unlikely that such a change can break any receiver, since it doesn't affect the drivers at all.
Anyway we have nothing to lose proposing a change.

A case has been made for it. The SF8008 Supreme shows signal below lock with only enigma2 modifications. Let's see what OpenPLi says.

Octagon SF8008 Supreme Show Signal Below Lock - [EN] Third-Party Development

Octagon SF8008 Supreme Show Signal Below Lock - posted in [EN] Third-Party Development: A way to display signal below lock has been found by ocean04. All that is needed to display signal below lock in the Octagon SF8008 Supreme are a couple of file changes. The problem is the files that need to...

The responses were exactly as expected, but let's hope they will get to try at least...
 
Listen to what they say, they being PLi contributors and devs. Some of these people have been coding enigma2 receivers for about 20 years. They are not trying to be mean. As I have already tried to say, It usually aint easy getting something added to OpenPLi.

So they need a video showing it working. I will see if I can do that. IMO, Now is a good time to ask for additions or modifications to the image because there is not a lot being worked on right now.
 
We also need to show them the comparisons between PC cards and the receivers. Is it @stephan94 who made these tests, if I'm not mistaken?
 
I don't think a video is needed now because they know it works.

Here is what littlesat was talking about with the erroneous signal:

I made a separate setting for the feature in Antenna setup. This way you have the option to turn signal below lock On or Off.

Fix for that was already in frontend.cpp, post #909
Just return snr only when it's smaller than that.
C: 
if (snr < 55536)
   return snr;
