Octagon SF8008 Supreme

It's what it says: You moved to satellite position 177W. I don't know of anything being there. Remove it from your antenna setup if it is unwanted.
 
I wasn't moving to 177w (not even activated in the tuner setting), but 117w.

Another error never displayed before:

81 KU blind scan.webp

Won't manual scan either, says scan error.

Same with signal finder. says scan error.

I guess something got corrupted..... will do a restore and rescan 81ku and 117ku and see if it occurs again.
 
For the command to blindscan, The SF8008 Supreme includes the orbit position. The SF8008 Does Not include the orbit position.I have set the SF8008 Supreme blindscan command to a hard code for the orbit that points to a location that does not exist. This was done because some Ku satellites were being blindscanned as c band satellites. The Ku frequencies that were found were being returned as junk c band frequencies. Hard coding the orbit to something that does not exist seems to have fixed the scan problem without effecting anything else. (This was discussed a bit earlier.)

Orbit location for blindscan used to be important. Some information about it is still embedded in the code. Here is an example of remarks found in one of the scan files:

Code: 
	if (m_flags & scanBlindSearch)
	{
		/*
		 * NOTE: for blindscan, the initial list of transponders does not need to contain valid transponders.
		 * Each of the provided transponders will be iterated (i.e. tuned with blindscan parameter) several times
		 * until a tune failure occurs. Each time a blindscan tune iteration returns ok,
		 * a new transponder has been found and will be scanned.
		 * Each transponder in the initial transponder list causes a full blindscan iteration run.
		 *
		 * Some of the parameters of the initial transponders will be used for the blindscan,
		 * but most will be ignored.
		 *
		 * For DVB-S, you need to provide a list of 4 transponders for each orbital position:
		 * one for each polarity (H/V or L/R), one for each band (hi/lo).
		 * The frequency defines the starting frequency within the desired band.
		 * The symbolrate defines the frequency search range, in MHz (frequency / 1000).
		 * The polarity defines on which polarity the search should run.
		 * All remaining transponder parameters will be ignored.
		 * So for each orbital position, 4 blindscan iteration runs will be done, one for each polarity/band 'quadrant'.
		 *
		 * For DVB-C, only one initial transponder has to be provided.
		 * The frequency defines the start of the blindscan.
		 * The symbolrate defines the frequency search range, in MHz (frequency / 1000000).
		 *
		 * For DVB-T, usually only one initial transponder has to be provided.
		 * The frequency defines the start of the blindscan.
		 * The bandwidth defines both the search step as well as the search bandwidth.
		 */

That stuff applied in 2005 or 2006. But I don't see it applying for us today because of the way the blindscan is more or less put into a binary file for satellite blindscan. Still though, It is interesting as to WHY the Supreme has orbit included in the command. You can't just delete the orbit either: The blindscan will crash if you do. But you can give it a bogus orbit location and "All Is Well..." Go figure.
 
I am a creature of comfort, and enjoy having the files for all four slots available at all times in case I want to do something. A hack has been made that basically goes like this:
if /media/usb/slot4.4 exists, then mount /dev/mmcblk0p16 /media/usb/slot4.

This hack fails if either folder does not exist in the proper location.
To use this hack make two folders on the SSD, named exacdtly slot4 and slot4.4
REBOOT the Supreme, and you will find all four slots mounted in the slot 4 folder, whether they are empty or not.
To end the hack, Delete the slot 4.4 folder and reboot. then delete the slot 4 folder.

Note: If you delete the slot 4 folder while it is mounted, OR if you delete anything in the slot 4 folder, then whatever you deleted is gone! Speaking from experience here, as I deleted the slot 4 folder while it was mounted and lost everything I had. Just be careful if you use this hack. It is optional. Doesn't have to be used. But it is available if wanted.

This hack uses about 1 GigaByte of space on my 1 TB SSD.

A sales video is shown in the link below. This sales video is comical as it shows the SF8008 Supreme scanning a satellite with predefined transponders (Not Blindscan). The video shows a 400 symbol rate transponder being scanned, but then the video is immediately cut so the result of the 400 symbol rate scan cannot be seen. Of course we know the 400 symbol rate scan failed. But it is kinda funny to watch them hide it.


 
A 32 APSK transponder has been active 24/7 for a few days on 89w. This transponder is a golf feed and will disappear soon. Mostly, anything below a 4.5 meter dish will be marginal for 32 APSK feeds. The Supreme is marginal at best on this transponder while the regular SF8008 fails to lock it. So there is a slight advantage with the Supreme on this particular feed.

My dish system doesn't do much better. The 32APSK locks and scans sometimes. Close to 14db is needed for an error free channel on my system. 32APSK could be considered the "Holy Grail" in satellite feed reception. It is good to see the Supreme working on 32APSK.
