Hi! Write a list of your ideas and errors of Octagon SX88 and send it direct to Octagon e-mail - here in forum not all ideas goes direct to Octagon. They communicate very well on facebook, also e-mail work with reply. I send 5 points DX relevants notes. When more people send this request, they maybe will programming it! So please. Send it:) My requests were: Low Symbol Rates blindscan (the absolutly PRIORITY for me:)), some problems with DiseqC and Dreambox Edit etc...

Now that I've switched to deleting TPs in place of channels, I'm missing the nice touch in the Channels Editor where the cursor would automatically step down to the next item after pressing OK to select. Now it's OK-DOWN, OK-DOWN... whereas in the other menu it's OK, OK, OK...

But if they fix this rather wide +/- 200ksps tolerance for a transponder match (surely a typo... +/- 20 maybe?), then I don't really mind about the former ;)

Select '0' 'operation' when in the transpnder list, and you can delete a whole satellites transponder in one go by pressing the yellow button.

Recent changes in the Octagon SF4008 firmware or image makes it possible for the SX88 to blindscan for it.

The Octagon SF4008 now only needs the frequency, symbol rate, and polarization in order to lock a DVB-S or DVB-S2 transponder. These are the same 3 items that the SX88 logs in a blindscan, so I can take the satellites. xml file from the SX88 and install it in the SF4008.

Yeah, that's fine for a completely fresh start... but I want to delete only those feeds which have accumulated at the end of the list... that way, after a new BS, they'll again be clustered at the end of the lists (after the always-on cruft), making them easier to spot.

Understood. I prefer the fresh start personally. I had Fortec Star receiver many years ago which you could select the SR range, that filtered out many of the broadcast channels, perhaps another idea for the Octagon developers??

Some more observations:
1. On a transponder of known SR 7120, the tuner will lock when instructed the SR is in the range +/- 100 of that centre value - much more tolerant of an off-spec SR than my Sf4008. A good thing in some ways, but...
2. If the tuner itself has a tolerance of +/- 100ksps, then why the hell this +/- 200 ksps on a transponder? It will store channels in the list it itself cannot lock (& I have witnessed that). It's either got 6 legs, or is just plain stupid.

Hello
I replied in another forum to the same question:


What is the advantage for a receiver with blindscan to be able to do that?
The engineers assume that on the same frequency there can not be two different transponders; if the characteristics of the transponder change, it becomes a new transponder, for feeds, the advantage of Blindscan (unlike xml lists for E2 receiver without blindscan) is that it is enough to make a new blindscan and we have the latest news. So no need to remember a list with different frequencies and 5 or 6 sr.

On the other hand what is very good with the SX88, it is the possibility to be able to return frequencies with only 1 Mhz of interval and it works (all the receivers are not able)
here an example ( screenshoot) in KA Band:

351981A1vert.jpg


Another example of the SX88's ability to differentiate between frequencies that are very close to each other with the same SR
Not all receivers can do it.

I just wanted to see how different receivers can handle it or not.
These four receivers are in fact not the same, one has no blindscan, the other he finds only from sr 1600 (that is too high) only two are reasonably the same.
The first is the Octagon SF4008 E2 UHD with no blindscan but sensitive, the second is the Octagon SX88, would not be bad if one day the blindscan could find 1600 below, and the last two are the very popular Openbox SX6 and the Openbox S3 Mini HD ,
The 4008 if you enter the parameters, no problem to see everything.
The SX88 "the same procedure" and everything can be seen.
With the SX6 unfortunately one must find out that without PC and an editor one can see only two of three frequency also with the Blindscan it does not work.
Only the S3 HD Mini can use the blind scan to find all three frequencies (one of them is wrong with the SR but not with the program) and can also display all programs.

@stephan94 Turn your dish to 7E.

Now let's simulate some day's feedhunting... You probably already have IMG3 EU stored. Delete that transponder, 11020V 7200. The channel will be removed too.

In the morning, let's imagine the SX88 blind scan finds a feed on 11020V 7050. Simulate that by adding a new TP (blue button) with those parameters. Later that day, we do another blind scan... IMG3 EU channel will be found (hurrah, great rx), but is stored as 11020V 7050, and will not lock (wtf? bullshit rx). This +/-200ksps tolerance on a TP match is to blame for that.

I'd like to incrementally add feeds, deleting feed channels as i go, but retaining the TP details... eventually that TP list will contain the history of all recent feed TPs on that sat. This +/- 200ksps tolerance renders that impossible.

Hello campag5242
I understand what you want to do, but I don't work like that with a blindscan receiver, before doing a new blindscan, I erase the old one.
there is another method you can do with the Sx88.
if you do a search "auto" it scan all the transponders that are in memory and erase those that are empty.
in this way after you can do a blindscan, and he will add at the end of the list the new transponders.

what you want is for receivers that have no blindscan (SF4008) and whose transponder memory is infinite, with your method you will quickly reach the upper limit of the Sx88 for the frequency number.
You already have a 4008, so you can do it.

have a good day

@stephan94 Thanks, I hadn't realised the "Auto" mode did that.

It seems crazy to me that the tolerance for a TP match is wider than the tuner's lock range... surely it should be the same, or (so as to have some margin), slightly narrower.

You have your way of working, I have mine. I'd like it even narrower - that won't affect your way of working, but will improve mine. I can deal with the TP limit being reached by archiving the list if needs be.

What is the make/model of lnb that you are using?

Hi @el bandido ... LNB is Technomate TM-4 universal quad.

I am not wanting to cover-up for the SX88, but the lnb you are using seems to be a £15 item. Inexpensive lnbs can drift and cause issues as you have described. If you get a good, professional lnb that costs 10 - 15 times more then your blindscans may improve on the symbol rates using the SX88.
Having worked on some blindscan code in the past, I can tell you that it is real difficult to fix one problem without starting another. It would probably help us most if there were more user selectable features available for the SX88 blindscan.

In enigma2, I have modified the blindscan plugin so I can ignore the transponders that are in the channel or lamedb file. The receiver looks for all the transponders it can find, then throws out the ones that are in or are similar to the ones in the channel or lamedb file, then it scans whatever transponders are left. (This is what you need for your SX88!)



One problem is if you set your transponder comparisons too tight, then you miss transponders. If you set the comparisons too loose, then you get duplicates. I doubt much if anything gets changed in the SX88 blindscan. It is what it is... If they changed the blindscan much from what it is now without adding additional user features, then you would probably start getting duplicate channels.

Sure, an LNB's LOF drifting can influence the frequency reported by the rx, but I fail to see how it can mangle the symbol rate. Replicate what I outlined in post #523 above with your expensive LNB & you'll see exactly the same.

Not sure if I have a problem with the SX88 or not. Put the dish on for example 5west and all the multistream channels show 'NO SIGNAL'. With the 1.2CM the signal is of course 100%. Do a rescan and up they all pop again all added once more!. So they are there twice now.

Am I doing something wrong.???? Even if the dish isn't moved they still show No Signal when put on Standby....and need a rescan! Is it a fault? Or does it need a factory reset and the software re loading? Either way a pain!
Thank you in advance for any advice.
