From the real findings of the TNAP image developer on legitfta.com.
The advertised capabilities of the 8008 supreme fall short of real world performance.
SR claims of the 8008 are exaggerated. And a direct quote from El Bandido.
From EB: "Octagon is advertising a high symbol rate of 80, which is ridiculous as this is 33% more than the specs of Avalink."
Although it does seem to be a nice receiver. And is pretty much the new kid in town. If you're interested in blindscanning with good results,
It would be wise to look at satellite charts and compare the results.
The findings come from a guy who actually buys many receivers and gives them the torture test. Octagon making performance statements to sell receivers is kind of fishy. I'm holding out on buying one myself. The Supreme, for its identical tuners. Until either the drivers are perfected.
Which is what Edision did with the Os Mio4k series receivers. Instead of going stagnant as is too often found with others.
Unless an even better receiver is released that can blow the SF8008 in the dust comes out. I'll hold out for the time being.
And another from him:
"Attempts to fix the low symbol rate in the SF8008 Supreme are being made. There have been three hi-dvb.ko test drivers as of today, and none of them come close to the advertised symbol rate of 100. As previously mentioned, it has been shown the SF8008 Supreme has Avalink AVL6261C demodulator which is identical to the Edision MIO 4k demodulators. Personally, I think this is a wasted effort, but the SF8008 Supreme should work as advertised."
An example of what I tried. And worked very well. Is taking the TNAP tuner drivers for my Os Mio4k receiver and putting them into an OpenViX image.
Quite an improvement when performing blindscans. Transponders and channels that were previously missed suddenly were there.
