I have both of them, and i prefer the sf8008

I sent back my Edision, was disappointed about the lack of low SR support.

The Octagon can go VERY low SR

Shame the blind scan on it, doesnt scan below 1000 either with E2, or the DEFINE (sx88 emulator) software.

not sure why the SX88's are being touted as being good blind scan receivers, when they cannot get TP's lower that 1400 SR

What is the fascination with picking up low SRs anyway? Anything using that low SR will be poor quality video, if video.
Can never understand people obsessing over the china radio channels on 45w, handy for locating the sat, but bugger all else LOL

Totally agree most of the high quality sports feeds use S/R 3,000 to 34,000 with the vast majority using 3,400 to 10,000 Symbol Rate,

This obsession with very low symbol rates is of little use to the serious feed hunter. :D

Those who fuss about low SR are DX enthusiasts rather than fans of sports feeds.

Only noticed this week that the Octagon SF8008's blind scan closed source binary blob got an upgrade sometime in 2020, and like the Edision OS nino etc Enigma2 boxes now reports found modulation scheme and FEC. The previous version had reported AUTO for everything. Sorry if already posted, but couldn't find mention of this on any forums, even Octagon themselves didn't seem to notice/announce the change.

Here's 7E from earlier today:

You don't have to use the cmd line to make use of this... simply turn off "Sync with known TPs" in the huevo's Enigma2 blindscan plugin and the values you see will be the found ones.

It's a bit of a faff on the command line as you have to zap to a channel to set the H/V 18/12V and lo/hi 22kHz LNB control before each quarter is scanned. I've no idea why it needs the sat's orbital position as last parameter: doesn't seem to make any difference if you set that to 0. Scan is plodding slow at 9 mins total cf my SX88 3-4mins, but unlike the SX88 doesn't have blind spots eg my SX88 never finds the Turkish football feeds.

Sadly, the frequency is rounded there to whole MHz, but in the kernel ring buffer log (viewed with dmesg) you can see the actual raw found frequency at kHz level resolution.

Best for Feed Hunting in my opinion

After testing several combinations I have found that this one works very well,

TM5302 HD + OP Gibertini 100 XP + Inverto Premium PLL Lnb set up is best for Feed Hunting,

My favourite receiver for feed hunting the TM5502HD has developed electrical problems & may have to be scrapped :eek:

So I have set up the TM5302HD now I knew that this receiver does not work well with the Inverto Black Ultra Lnb so I looked for an alternative Lnb with high performance,

I have set up the OP Gibertini 100 XP with a TM5302HD,
I tried several Lnb's & the best results came with the Inverto Premium PLL Lnb

Sadly the Inverto Black Ultra & Golden Media 201+ worked well on most feeds but Direct to Home transponders on 28.2°E,19.2°E & 13°E overloaded signals with the TM5302HD = no signal,

The Inverto Premium PLL Lnb with the OP Gibertini 100 XP & modified Lnb Arm (I cut off 22mm at the end of the arm) :eek:

Now this set up copes much better with low feed signals & high DTH transmissions with the TM5302HD is a perfect match :thum:

For me, AB Cryptobox 750HD does a good job. It's blindscan is a bit slow, but it's able to find BISS keys automatically

I use my Octagon SF8008 with Multifeed and with the Blind Scan I easily hook the Feeds. Then with OScam and SoftCam.Key I configure the CW in Biss.
