Hi Dave
A very minor thing I found. Changing the lime gain is not saved as default. If I change it to 70 say, it always goes back to 90 on next boot. Saved ok with presets.
Many thanks
John

Thanks for reporting this. I have found and corrected the error with Lime Gain. The fix should be in the next release.

New Portsdown Stretch Software Release 201810270

This major new software release includes the following features:
  • Initial implementation of H264 encoding with audio
  • Nightly streamer reboot
  • Reduce "popping" on streamer audio
  • Improve C920 selection logic
  • Correctly load Lime Gain after boot
Enormous thanks to Evariste F5OEO for implementing H264 Audio. Full details here: https://wiki.batc.org.uk/H264_Encoding_with_Audio. The streamer improvements are intended to improve the reliability and quality of the Portsdown repeater streaming system; more details here: viewtopic.php?f=69&t=5703. Thanks also to Mike G0MJW and John G8BXH for bug spotting.

PLEASE NOTE THAT THIS UPDATE TAKES AT LEAST 25 MINUTES TO COMPLETE, AND CAN TAKE UP TO 2 HOURS. Slower SD Cards take longer to compile the new audio software. Please contact me if you have a problem - if the update runs longer than 3 hours or freezes, do not try a second update.

Dave, G8GKQ

Hi Dave,
Just done the update on my (non +) system, it took just over 20 mins and looks ok. Thanks to you and Evariste for amazing work.

Just upgraded to Stretch 201811030 and my animated testcard lacks any animation? It's always worked before. Running on a RPI3B+ on a 16Gb Sansdisk.
Output to ugly, H264 DVB-S.

Have I upset it?

Hi Gareth,

I updated my system over the weekend and found many of the settings had become corrupted, what is more the changes i made to put them right woouldn't stay put.

Normal operation was restored by the restore defaults option.

Kind regards, David.

Hi Gareth

If you check the transmitted signal, you will find that the animated test card is working and much smoother than before. It is just not displayed on the touchscreen. Documented here: https://wiki.batc.org.uk/H264_Encoding_ ... im.29_Mode

Thanks David and Dave for pointing out what I read the other day -sorry!! It spent a lot of time doing the Lime SDR compile and install this time, if it makes my Lime work, great, just how much can a RPi be made to do? Inspirational :-)
