progress but not yet decoding PMT

really hope this can be achieved

editing lamedb is a laborious process when using motor settings,

keep up the good work !!

Sorry about that, looks like a spaces and tabs mixups:

which can cause an error

  char *caPMT = (char *) calloc(1024, 1);
  int length_field;
  int toWrite;
  caPMT[0] = 0x9F;
  caPMT[1] = 0x80;
  caPMT[2] = 0x32;
  caPMT[3] = 0x82; //2 following bytes for size
...

campt in Py3 has zero length 0x00 , while in Py2 it has length 0x1e

[WanWizard]

You're passing a string to bytearray, not a sequence of bytes.

    capmt = bytearray(b'\x9f\x80\x32\x00\x03') # capmt start

In Python 3 there is a difference between string and bytes.

[EnoSat]

zero length/size means that the SID and other data will not be transferred to the campt

I apologise if this question will appear lame and/or very old.
Actually, I have seen right now (I am writing this on top, but as last edit to my post) that I already put this question a couple of years ago, but I received no answer.

 

I am getting Satback OK since the very first moment the remedy was found by doublet&C.. So, no problem in this.

I can also (usually) edit lamedb properly to achieve the result.

 

But if I then edit my channels with DreamBoxEdit (7.2.1.0), some of the extra parameters get stripped.

This is very inconvenient, since reduces a lot my flexibility to update the channel list, other than from the receiver itself.

 

Even in this thread (very many many) pages up (page 4), at the time when the trick had not been discovered robbie says that DreamBoxEdit keeps all extra options.

 

But this does not happen in my case, at least not in the way I am using it (pretty standard: load->edit->save, and then the standard procedure to upload it to the receiver by FTP).
After saving, some extra options are not there any more and lamedb needs some editing (again).

 

Am I missing something? Is there a way/other software to freely edit the channels without damaging BBC entries after the first necessary editing "by hand" in lamedb?

 

Thank you!

However, this is still a user intervention in the lamedb file 
DreamboxEdit is an old program, some c: are causing it problems.

It looks like 27.5W Satback will soon be removed. A new transponder has been opened on 15W carrying an exact copy of the transponder on 27W.

Spending my days scouring the net for the softcam keys etc.

[sleepy]

It seems to be a transponder very difficult to catch outside roughly the area normally served by the original FreeSat service.
It is a no go for East/SE Europe.

It is also interfered with by signals at near frequencies on different beams of the same satellite. So, a 15 m dish might not help if you are in the wrong place.

 

I fear it was good until it (will) last.

 

I seize the occasion to send again many thanks to the people who here helped to have this service available soon after FreeSat transferred in its narrow beam.

 

I still hope that someone can come out with a similar new bright idea, at least for the people in the right places for this new service, but no one can easily fight against physics for the others.

[erojohn]

Hi.

 

I just checked 15W here from Denmark and i have no signa lock on that new TP.

The EU beams have a fine signal.

 

Are we sure this is a normal DVB-S2 signal and not a IP stream or DVB-S2X ?

 

Is anyone getting a lock on that TP ?

 

Cheers

[sleepy]

It should be a normal S2 carrier.

 

People in the right place (not me) like you are able to get a lock on it.

In some moments the TP has briefly been off, so that can be an option.

In Denmark, the NorthSea beam can already be interfered with by the MedCentral beam

Where do I find bbc_pmt_v6.py? I'd like to give it a try as I seem to have a mixed up lamedb probably full of redundant parameters. Should lamedb be different for OpenATV and OpenPli?

Hi EnoSat.

 

Ive done a bit more testing, and i do see a signal on 11044V, and can see its a QPSK at 44110 SR and 9/10.

It is too weak to get a signal lock for channel search. There is a signal right below it with out any guardband, maybe thats a signal from the Medcentral beam.

I will do some more testing, and report back, if im able to get any more useful data.

 

Cheers
