Part 2:
Analog and DC2 channels.

Here is an example of an Analog channel G7-12 and G7-13 is a DC2 channel.
The blue highlighted text is analog
The red highlighted text is DC2 for SR rate of 29.27
The orange highlighted text is also DC2 but a different SR rate of 19.51
The Green highlighted text is DC2 on low SR channels less then 19.51 so it is the same for 11.71, 7.32, 4.88 or any SR lower then 19.51
Notice how the first area next to the channel number for DC2 is the same but after the Frequency it can change.
For DC2 channels this is where it gets real interesting.
1) you have what is called the "BIT-STREAM" This can be bit-stream 1 or bit-stream-0 and in some cases it can be Bit-Stream-Both.
This is where a commercial receiver comes in handy to determine what it is.
Here are 2 channels from G7. Channel 117 is bit-stream-0 and Channel 118 in the same mux (set of channels) is using bit-stream-1.
015-G7,00117,0,0,0,0,03238,013,00001,0,80,H,1190000,1,1,0,29.27,7/8,10,015,10,015
015-G7,00118,0,1,0,0,00000,013,00002,0,80,H,1190000,1,1,0,29.27,7/8,10,015,10,015
notice the set of numbers highlighted in RED.
This is where the numbers after the channel number can be different according to the bit-stream.. However since it is the same SR of 29.27 after the frequency that section remains the same.
OK so what have we got here?
G7-12 is the first one posted here and that is analog, see the NTCS at the end of the line...
G7-13 is showing a DC2 setting in the analog section of the file. So that means there may be a DC2 channel below channel 24 someplace if there is actually a signal to be seen or locked.
In this case G7-13 shows a DC2 mux with a SR of 29.27 and FEC of 7/8.
Remember where the guide info goes? well the number to the right of it is also reflecting the transponder number here also. Look at G7-117 above... There is guide data there showing 03238 and directly after that guide data it shows 013 and the 013 points it to G7-13 in the analog section.
If you do not have this number correct here you will have problems.
Once you realize that the above highlighted areas are the only ones you really need to know it goes very quick.
After some time you can do it in your sleep.
Now your going to ask if you noticed it.... What is going on with G7-902?
I only mentioned corresponding DC2 channels to analog channels 1-24 but this is not the case here....
Well, this is because some receivers like the 920's and 921 receivers can not lock these lower SR channels and some satellites will create a channel roll-over or channels locking up and not going properly so the low SR channels reflect an undetermined analog channel in this case 25.
This was a real stumper for a long time to figure out a way around so all the channels could be put in one set of maps and all the receivers would work properly.
Earlier we had 2 sets of maps one for a 922 and another for the 920 & 921 receivers.
Now the newest maps have everything in there on the proper satellites like it should be for all receivers and the tests so far are working good as it was just done in the past week.
**This is not the case on all the satellites** some are fine and only a few have this problem with the low SR channels**
Lets go over a bit here:
004-X4,00318,0,1,0,0,02001,017,00001,0,80,H,1250000,1,0,0,19.51,3/4,10,004
This is from X4 digital channel 318
The bit-stream is 1 here (0,1,0,0,) if it was 0 then those 4 digits would all be 0's.
Guide info is 02001 and it corresponds to Channel 17 and the set of numbers after the 17 represents the SN (service number 1 here) it is Horizontal polarity frequency of 1250.000 and a SR of 19.51 and FEC of 3/4.
Locate this above on the X4-17 example provided, as all DC2 channels info is consistent with regards to Service numbers (which is needed to lock a DC2 channel)... etc....
Have you caught on yet?
If there is something I missed so far or something you don't understand ? ask....
You have the #9 maps from the website so use it as a guide.
Now lets look at an entire set of channels on sat tile G7:

See the commented line directly above here... this is in-between each different satellite.
Using all the above info see if you now begin to understand what is needed to rewrite the maps.
Don't be intimidated by the large file of text. Work on one sat at a time.
Now if something changes you can basically write your own maps and send it to your receiver to see if it works or not.
If it is right then on diagnostic screen C ... Options > 6>0>5 right arrow over 2 times.
You will see a 7 on the top left of the screen... This is on a DC2 channel and that means that you have a DC2 lock. Now use the left arrow one time to diagnostic B screen and if you see MP at the very bottom 2 lines, if so then the channel is encrypted. US there means that either your SN is incorrect or there is nothing there.
Of course if you find something in FP or ZK you will see a picture unless as is the case on a couple channels up there on some satellites they are in FP but the screen is blank as there is no programming at that time playing. Check those out later....
If there are any questions feel free to ask as doing this for a year some things are like second nature to me so I may have missed something.....
