I have just released a new version of the Portsdown Buster software 202003140 (the Pi Day build?). Testing has now reached the stage where I can recommend this as the new build for anyone using a LimeSDR Mini. The main new feature in this version is that there are 10 fixed QO-100 uplink frequencies selectable from the frequency menu.
Thanks to all the beta testers for their comments - I have decided to keep it simple!
More details in the forthcoming CQ-TV.
One question, are those 10 frequencies configurable?
Don’t forget some of us are up-converting from UHF so hard coded 2.4GHz frequencies are of no use.
No, not yet. But I'm sure that you can:
Simply edit the 3 lines below https://github.com/BritishAmateurTelevi ... uch.c#L284.
The top line is the actual frequencies, the second and third the button labels. This will work, but menu 1 won't display your uplink frequency unless you also edit https://github.com/BritishAmateurTelevi ... h.c#L16437 and the offset 2 lines below it.
Then run the alias "ugui" from the command line and it will compile, install and run your new version.
I'll look at storing a configurable offset in one of the config files in a future build.
Now we are nearly all sending H265 what's the best way to view it? UDP I assume - but I thought the PI could do some H265 decoding- https://forum.kodi.tv/showthread.php?tid=343068
It would be really useful if you were able to use the info at that link to build a Pi 4 that would decode and display H265 sent to it over UDP (or in due course through a fifo). I could then try and port longmynd on to it so that it at least worked as a receiver.
It's a massive job to port the whole Portsdown on to a Libre-elec based build on a Pi 4. I was going to get Portsdown working on a Pi 4 on Buster first, as Raspberry Pi foundation have promised that H265 display will work on Buster/Pi 4 in the future.
I will give it a try later this week.
Just about to create a card.
Initial testing with the normal firmware seems good. So you can stick with the same as you use for Narrow Band.
Just got it going with the custom firmware today but it looks easy enough to revert, so I'll try that at some point.
In the meantime, next I'll try out the Video stream to Portsdown from vMix script. I'll let you know how I get on
Great job! MUCH appreciated,,,,,
Hopefully next week.
Dave, I recompiled as you suggested to change the preset frequencies. However I didn't change the button text or the display offset code as I found configuring a transverter entry called QO-100 with the necessary offset for my system works fine. Selecting that transverter then displays the correct uplink and downlink frequencies.
