Back in October I quietly changed the SIT numbers on the #9 maps at the web site.
for instance this was an old SIT number
OLD >> SIT 005-58,058.0,3633,P6,C
NEW>> SIT 118-58,058.0,3633,P6,C
I have purposely left off the rest of the info from the sit lines here just to show you what needs to be changed if you want to keep your current sat position settings if you use your 4d as a dish mover.
You can copy and paste all the channel info under the current SIT line you have in your receiver and remember to change the SIT number on that SIT line though.
In the case above you would change the 005 to 118 and then under that line all the new channels from the #9 maps on the web site.
In the case here 3633 would be the dish position number, on the web site it is all listed at 5000 and un-programmed in.
So if you wanted to keep the dish position number you would in the case in red change the 5000 to 3633 or whatever your dish position number is.
Now, 2 new individual sets of maps have been posted on the website
9_zzz for a 922/905 receiver only!
and
9_xx for the 920/921 receiver.
The difference is in the low SR channels ,(that the 920/921 receivers can not pick up anyway), taken out of the 9_xx maps.
All the low SR channels are in the 9_zzz maps for the 922/905 receivers. but the 920 receivers will experience channel rollover problems due to the changes in the frequency on certain mux's if you use the 9_zzz in a 920/921 receiver.
The reason this will happen is so that the 920/921 receivers will not have any problems with channels locking up or what I call a roll-over problem. This is due to certain low SR channels that those receivers can not handle or lock anyway.
This will allow the maps to be more precise for the 922 receivers on certain channels on Galaxy 15 to come in very fast unlike what a couple of them do right now, and for future changes that can occur with these low SR channels.
Also there is was another channel lineup upheaval with the way some channels are currently numbered in the maps.
ALL of the low SR channels were placed in the 900 channel range.
The MC channels on Galaxy 14 were also placed in the 900 channel range with a different line up to try to keep the different types of music placed together in a better order.
Other channel changes included the W5 lineup so that the movie channels now begin at channel 62 and those were placed together differently then before.
Now, Encore is all together, as is Starz!, HBO, Cinemax, Showtime etc...
Added M3 sat tile to the maps since it is to be launched in December.
Anik F1 was reduced down from 24 channels to just 2 (a Horizontal and Vertical Channel only)
to prevent Shaw from downloading their signals into the receivers and corrupting the maps by overloading the TDT. This would occur on F1/05 with a new signal they were testing out and some who had gone there overloaded their TDT on that c-band sat.
(Thanks to those who reported this so we could fix the problem for others)
So if you loaded in maps before October 21, 2012, the new maps are very much different now.
If anyone did not understand what was said here post your questions below and I'll try to give an answer.
The only problems I can see for those who loaded in maps before October 21 are for those who use the receiver as a dish mover. If the 4d you have is slaved then you have no problem. If used as a dish mover then 20 minutes tops of work to rename the SIT number on each SIT line and saving the text file and creating it into a new bin is all you need to do.
You can always load in these new maps and just re-program in all your settings if you wish
One thing to remember is this.
Sat tile M1, A1 and Ai can be used at any location you wish but those sat tiles are active in the mappings and can change by you going to various places. They were never taken out or off certain satellite maps that are still being broadcast up there. If you delete them they will only return as a phantom sat tile you will not be able to access or program them in.
As they are currently they can be used for different sat place-holders you may want them for.
On a 920and a 921 receiver NEVER un-program any sat tile you had programmed in.
It can disappear on you permanently until you reload a new map set in the receiver.
This is due to the maps not being broadcast any longer via satellite.
If you have redone the maps earlier and want the newer ones I personally recommend that you dump the your nvram out on the X4 sat tile and resend the new maps back to the receiver at the X4 position.
If your 4d is just a slave then that does not matter but it makes a difference if it is a dish mover and you did not want to spend an hour re-programming in all the sat positions again.
