SES1 strange channel error

[jrose]

I have a strange problem, maybe someone else has seen it. Quite a while back when SES1 just came into service I did a scan on it. I have two channels on my SV360E one is called J1-1890 and the other J1-1891 both are at 11822H 5699. What is strange is that both of these are in a weird font, not the usual SV type channel lettering. The other problem is that they are a box freezer. I can go to the channel and it has no signal. But as soon as I go to settings and use channel delete the box totally locks up....just on these two channels. Never seen problem like this with any channels. Im sure I could do a factory reset but I have quite the extensive channel scan and wildfeed library and would hate to lose that much invested time. I can't remember at the time if it had any picture or what the story was on the channels??????? anyone else ever seen this?

Give me a moment and I will take a look at it.

There is no TP11822H on SES1, also nothing on Lyngsat or Satbeams for that TP.


No idea why you have one......??

[jrose]

could it be from the old AMC sat? either way why would it cause freezing on just these two channels when I go to erase these, I delete channels all the time...and the weird style of font? Didn't think box could do that, never seen any other time until these two. I will try a transponder delete. I can flip over the channels while on the sat its not causing grief that way.

Satbeams has some the most up to date TP listings right now, but it only shows the one TP at 12120, Lyngsat shows more, this is funny....

The active TP's that I have are...

11860H, 12060H, 12120V.

11860 has TAN TV

12060 has BIO and HISTORY

12120 has CGN TV and others.

try a factory reset, then you will need to redo your antenna settings and rescan, but that should clear those bad channels for you

I think receivers can just sometimes get discomboobulated...I know I sure can. :yes:


I usually think deleting the TP, or editing it manually will solve a lot of those type issues

I totally agree with you Gold. I had many problems with my pansat 3500, it had a mind of its own. It once scanned in rtv with a different tp frequency, then went back to old tp freq. the next day.

There is a lot of old hardware at that location, and a couple of satellites close by, if two or more transponders have a bit of a problem you can get what is called Intermod, intermod is when two or more RF signals combine in some piece of hardware, transistor, mixer or antenna that may have a problem, (trying to be non technical on this) this can cause a second, third, fourth or fifth signal, this new signal can be in the correct bit format to cause a mysterious channel to appear.

This use to happen a lot in the old analog days, the fix was several band pass band reject, hi pass or low pass filters, if one of these filters develops a problem the mysterious signal can be formed.

It can also be a piece of hardware, antennas are resonate to the frequency they are transmitting, if it has been modified or damaged it can resonate at a different frequency and could act as a frequency mixer, this would cause the creation of the second, third, or fifth harmonic to be re-transmitted as a real signal.

The math in this gets complicated but a simple way is to add the two major channels and divide by 2 thus producing the third channel, there could be more frequencies involved but that gets complicated and it doesn’t have to be the same ones as what you’re trying to receive, it can be several lower frequencies or several higher frequencies mixed with a lower, we had computer programs designed to figure out the after products of all frequencies being transmitted to what would be produced and give us a list of all harmonics, then we could add the correct filter to eliminate it.


Oppps too much coffee, sorry my fault.

Also you can try unplugging the antenna cable after properly shut off/unplugging of stb. The turn stb on and delete those channels, you shouldn't have any problem as you will not have any signal coming from sat, then turn off again, plug the coaxial at stb and turn it on, and you still have all your saved data.

You could use Channel Master to delete the offending channels... Use version 1.19.02 as the latest version doesn't save the channel file properly...

hey jrose i seen your post on other forum i'll try to see if i can scan in that tp
------------------
nothing there on those settings and i have a good strong signal from that bird


Im not sure on sv software but is there a way to save your channel list on your computer?
if there is you should be able to manually remove those channels then write it back to sv
