Octagon SF8008 OR VU+ Duo 4K SE?

[victor64]

Good Morning,
I must admit that I checked only in the TV list since some times a new channel appear in this list. Later I will check. Thank you very much for all your help.

Just one question more. With the same system do you receive Sky Radio on 16 East ?

Hola 'victor64'

Sorry, not much time, again!
Just scanned.
The 'Service Information' screen should help identify with all the PID data.

Best wishes.

I have received the supreme and comparing with old model this new has more gain in this tuner. I notice a little bit speed in the net and the box in generally. I´ll check more about the SR that should already works. The first view it´s very good I likes the picture quality and how it works.

Hope you are well yourself.
Would be great for us here, when you have 5mins, to let us read of your findings up to now re: the 'SUPREME'.

Just about to post my own update with the 'SUPREME' low SR capabilities.

Thanks.

Probably the wrong thread, but has anyone taken the lid off the Supreme and compared the board/chipset to that of the earlier box ?

Would like to see what others say about the SF8008 Supreme symbol rate. Here is what I have found about it:

Octagon Lies about the symbol rate capability of the Sf8008. They advertise symbol rates from 100 to 80,000 (.1 to 80 Or 100,000 to 80,000, 000). The real symbol rate capability is 1,000 to 60,000 (1 to 60 Or 1,000,000 to 60,000,000). The maximum symbol rate does not apply to every modulation type!

Octagon has AVL8281C demodulator, which is shown as AVL62X1 in the receiver menus. Here is what Avalink, the company that makes the AVL6261C says:

For AVL6261C, we support the symbol rate down to 1MSps with performance guaranteed. For low symbol rate, AVL6161C can work till 0.3Msps with performance degraded and long acquisition time.

So any symbol rate below 1,000 or below 1MSps may or may not work. It's that simple. Edison 4k receivers also have the exact same AVL6261C demodulator and the best we have been able to do with it is a somewhat usable symbol rate around 500.

Some test drivers Octagon has provided also open radio channels in the 500 range, but these test drivers broke other things in the process. Ghidra shows an open-source license so Octagon should release the source code for these drivers like Edision has done. In reality though, I don't think Octagon is doing anything. Probably someone in China is coding the driver.

Anyway, the real symbol rate capability for the SF8008 Supreme is 1 to 60, 1,000 to 60,000, Or 1,000,000 to 60,000,000. Any transponder with a symbol rate less than this may/may not work. And most likely, a symbol rate around 500 will be the absolute lowest usable, which is the same as the Edision 4K receivers. Best of Luck!

Since I once started this thread I now must say I now have tried both the Octagon SF 8008 and the VU+ DUO 4K SE for quite some time and my conclusion is the VU+ is the better one of the two technically.
BUT the VU+ costs almost twice as much as the Octagon so when it comes to value for money the conclusion is not that obvious.
