Pluto SDR High 4000, KSB

Pluto SDR High KSB rates
Well after much fiddling and mayhem...
We have the Pluto Pumping out the video at 4000 KSB (It’s a VK thing)
Thank To Joe VK3TET and a lot of mucking around its all possible to up the Anty.

I find most of F5OEO excellent firmware will do the job, just some a tad better than others.
Using the Adalm Pluto Real, or AliExpress, and even the Pluto Plus, with the correct FW.
All been Tested and all work pretty well.
A lot has to do with the content you are showing.

Pluto works well at 4000 KSB, Video Bit rates 3500 and up.
If you happen to use a very high bit rate video then you will get the NULL Packet Syndrome to many.
also, the other way around to little Null Packets and well its will also fall in a heap as well.

It’s a balance between what goes in to what comes out.
Most have had good success with USB2 between Pluto and OBS.
Same also using the Amazon Fire Stick, USB2 ethernet adapter. https://www.amazon.com.au/dp/B086WCG4SR?

Settings in OBS need to be adjusted to suit,
Main streaming Link for OBS in our case for VK3RTV
rtmp://192.168.2.1:7272/,1287,DVBS2,QPSK,4000,23,-8,nocalib,800,64,Callsign,

192.168.2.1 is using the USB cable all seems pretty good

These instructions or stream settings can be found in the PLUTO web Info when you log into it.

We now have about 8 to 10 users Putting their Pluto's to good work locally on VK3RTV REPEATER,

It’s all a bit of Fun really.

OBS and a Pluto Only, no other Hardware required except for the Amplifier chain.
