The symbol rate thing is a limitation of the LNB. Did you manage to scan in the multistream channels on 5w?

Which transponders are being missed by the blind scan? On the Primo it never blind scans 11053H 23000 on 28.2e despite being blazingly strong.

Not sure its entirely an lnb thing ?
On 45' West 11.605H there are five radio channels with a symbol rate of about 980.
The TM7102HD & TM F3/5 can download & play these but the SX88+ can't even though it shows the signal.
On 5' West there are radio channels with a symbol rate of between 540 & 670.
None of my three receivers can download these.

I asked on the Octagon support forum what was the lowest symbol rate that the SX88+ could download & was told by Octagon support 1500 to 2000 which I believe is not quite accurate as I believe it can go lower.
I understand that the Octagon SF8008 can go as low as 200 but I don't have that receiver.

I also asked Octagon support if in a future firmware update would it be possible to be able to enter a set of frequencies on the Sx88+ between which the receiver would search?
They said they would check ?

I meant to add as well that I didn't make a note of the transponders the SX88+ missed in its blind scan.
All I can say is that it happened on two separate satellites.

I tried 5w on the Primo with a PLL LNB and no joy with the low symbol rate radio channels either.

On 45w if you change the symbol rate to 1000 does that make a difference? That works on some receivers which have an artificial 1000sr lower limit. I can't see 45w so can't try.

If you make a note of which transponders are missed and we can discover a trend, perhaps Octagon my try to fix it.

If I come across any more missed transponders I will make a note.
I'll try the 1000 symbol rate at 45' West when I have a chance.

I had a few minutes there to have a look.
The dish happened to be on 21.5' East so I did a blind scan.

When the scan had finished I went through the transponders & by changing some of the symbol rates & putting in some transponders I was able to get extra channels which the blind scan had missed.
11516 H 3991 BWTV
11520 H 2220 Iran Press
11558V 1500 & 11559 V 5000. Both MBC Test
11683 V 1480 CH1
11690 V 1300 & 11691 V 1447. Both Yemen Today.
11537 V 2963 Service 1
11186 V 3189 BWTV
11564 V 3333. Feed HD

You switch to some of the channels & it takes about 10 seconds to show the channel.
Strength on the channels in question is 70% & Quality is 40%.
Now the Sx88+ obviously takes a little while to lock onto these channels.

Now I bought the Sx88+ as a more modern receiver to move my dish over the old TM7102HD.
It is nice it has a blind scan but I wouldn't trust it.
This is the 3rd satellite now that I have found it missed channels on a blind scan.

I was tempted to get an SF8008 as a test especially since it can go as low as 200 symbol rate & it can blind search between a set of frequencies but after my blind search experience with the Sx88+ I'm not so sure.

Give me a couple of hours and I'll try same on an 80cm dish, olde LNB and the SF8008. It's cloudy here with constant drizzle, so the results could be similar.

Will let you know if anything is missing.

 

[Channel Hopper]

Database on the sf8008 suggests the satellite slot is 21.6East. Will scan there first

Blind scan down to 1MS/s

 

[Channel Hopper]

Resullts (scan for clear channels only)

 

[Channel Hopper]

Correct slot in a moment (all channels, symbol rate extended to 55MS/s, just in case )

 

[Channel Hopper]

Scanning stopped at 67% then the iPod battery went flat.

A number of additional German channels though (WDR//Die Maus/Cosmo/1live diGGi) etc.

I can't take pictures of the results until I find the charger lead.

I do not think it is a valid comparison between the SX88+ and the SF8008 re blind scan functionality as the SF8008 uses a different firmware (Enigma 2). However, if you are not happy with the SX88+ made by Octagon then perhaps a receiver from another manufacturer might be appropriate?

 

[Channel Hopper]

Ignore the German entries, breakthrough from 19E.

Will try scanning with a 1 degree force field this time.

I know the SF8008 uses enigma 2 firmware.
Just wanted to compare the blind scans of both receivers ?

If using a small dish, the best option for this type of comparison may possibly be to use a satellite that has no close neighbours otherwise you will get bleed over from the neighbours. 16E might be a suitable satellite as there is nowt either side for 3 degrees that is generally available in Ku-Band for a UK location. The other satellite with a similar neighbourly profile would be 36E.

Ideally, a test using the same dish at the same location would give a true picture. However, slightly different size dishes at different locations should highlight any obvious differences.

Thanks for that Moonbase.
I'm using a 1.2mt dish & the comparisons I took using the two TM receivers I have & the SX88+ were all taken from the same satellites.
The disappointment for me was that the two older TM receivers constantly brought in the transponders / channels that were available while the Sx88+ missed transponders / channels that were clearly there to be seen. Once I entered the transponder information or in some cases edited transponder information the SX88+ brought them in no problem. There were of course transponders that none of the receivers could read because of their low symbol rates. I wasn't to worried about spurious signals brought in from nearby satellites as these are easily discounted with reference to the satellite charts available.
As I said previously I got the SX88+ as a modern replacement for moving the dish & not for its blind scan ability. Its just a pity that the SX88+ blind scan doesn't function correctly. It may be down to the firmware which can be improved over time with regard to the mechanical limitations of the receiver itself of course.
I was intrigued to learn that the SF8008 was capable of going down to a very low symbol rate & was just wondering if its blind scan function was very near to perfect or just average.
I understand of course that its an Enigma2 firmware receiver & very different to the SX88+ in that respect.

If I purchase an Octagon SF8008 from WOS I get the option of having OpenVix flashed to the box.
Will it still have the default Octagon firmware in the receiver as well or is that overwritten by the OpenVix firmware ?

It depends if WoS flash OpenViX into one of the vacant multiboot slots or if they overwrite the default factory image which is probably OpenATV.
There are four slots available in the SF8008, each slot can accept an image. The multiboot function allows the user to boot the receiver from a choice of four different images, subject to all four slots being populated.
