gibgib Posted March 8, 2007 Share Posted March 8, 2007 Can someone please take a look at this file & let me know if the parameters are correct. I am using the Bald Knob transmitter. The set top box is a hybrid terrestrial/ satellite type (Dreambox 7025s) <?xml version="1.0" encoding="iso-8859-1"?> <!-- useable flags are 1 -> Network Scan 2 -> use BAT 4 -> use ONIT 8 -> skip NITs of known networks and combinations of this.--> <locations> <terrestrial name="Sunshine Coast" flags="5"> <transponder centre_frequency="767625000" bandwidth="1" constellation="2" code_rate_hp="2" code_rate_lp="6" guard_interval="1" transmission_mode="1" hierarchy_information="0" inversion="2" /> <transponder centre_frequency="704500000" bandwidth="1" constellation="2" code_rate_hp="2" code_rate_lp="6" guard_interval="1" transmission_mode="1" hierarchy_information="0" inversion="2" /> <transponder centre_frequency="788500000" bandwidth="1" constellation="2" code_rate_hp="2" code_rate_lp="6" guard_interval="1" transmission_mode="1" hierarchy_information="0" inversion="2" /> <transponder centre_frequency="746500000" bandwidth="1" constellation="2" code_rate_hp="2" code_rate_lp="6" guard_interval="1" transmission_mode="1" hierarchy_information="0" inversion="2" /> <transponder centre_frequency="809500000" bandwidth="1" constellation="2" code_rate_hp="2" code_rate_lp="6" guard_interval="1" transmission_mode="1" hierarchy_information="0" inversion="2" /> <transponder centre_frequency="725500000" bandwidth="1" constellation="2" code_rate_hp="2" code_rate_lp="6" guard_interval="1" transmission_mode="1" hierarchy_information="0" inversion="2" /> <transponder centre_frequency="662500000" bandwidth="1" constellation="2" code_rate_hp="2" code_rate_lp="6" guard_interval="1" transmission_mode="1" hierarchy_information="0" inversion="2" /> <transponder centre_frequency="585625000" bandwidth="1" constellation="2" code_rate_hp="1" code_rate_lp="6" guard_interval="2" transmission_mode="1" hierarchy_information="0" inversion="2" /> </terrestrial> </locations> Results doing an auto scan off this script : 767.625MHz ABC (local) missing 7 Brisbane missing 7 Sunshine Coast 746.5MHz Nine (Brisbane repeated) 809.5MHz Win (Local) 725.5MHz Ten (Brisbane repeated) missing Ten southern cross local 585.625MHz SBS (local) I know about the guard interval change on ch7 which has been taken care of with a "1" selected. Having no channel 7 at all is a pain. I would be happy to just get the local version only. Signal strength is good. Link to comment Share on other sites More sharing options...
gibgib Posted March 11, 2007 Author Share Posted March 11, 2007 Ok then. Here are the possible settings for the dreambox script: centre_frequency="value" (frequency ie. "530000000") bandwidth="value" (0=8Mhz, 1=7Mhz, 2=6Mhz) constellation="value" (0=QPSK, 1=QAM16, 2=QAM64/Auto?) code_rate_hp="value" (0=1/2, 1=2/3, 2=3/4, 3=5/6, 4=7/8, 6=auto) code_rate_lp="value" (0=1/2, 1=2/3, 2=3/4, 3=5/6, 4=7/8, 6=auto) guard_interval="value" (0=1/32, 1=1/16, 2=1/8, 3=1/4) transmission_mode="value" (0=2K, 1=8K) hierarchy_information="value" (0=none, 1=1, 2=2, 3=4 ) inversion="value"2 (0=none, 1=on, 2=auto) If anyone can give the following from a working Digital STU on the Sunshine Coast I may be able to manually add the channels in the channel list: Transponder ID Network ID Namespace >For channel 7 brisbane, 7 sunshine coast, & southern cross 10 sunshine coast.

digitalj Posted March 11, 2007 Share Posted March 11, 2007 The code rate for 7, should be 2/3, try changing the code_rate_hp for 7 from 2 to 1. Link to comment Share on other sites More sharing options...
alanh Posted March 11, 2007 Share Posted March 11, 2007 gibgib, Most people who need to do this find in the end that the signal is not good enough. Most searching in the installation menu will find the stations. Read Get the Best Reception, Sunshine Coast and read the links. So be sure that signal is adequate.

gibgib Posted March 11, 2007 Author Share Posted March 11, 2007 The code rate for 7, should be 2/3, try changing the code_rate_hp for 7 from 2 to 1. Yes I had tried that. Funny thing when the box scans in auto it seems to forget the script settings, eg for WIN it has 1:2:5:2:1:1:0:2 in the channel plan yet the script has 1:2:2:6:1:1:0:2 gibgib,Most people who need to do this find in the end that the signal is not good enough.

AlanH I have a masthead amp with new UHF antenna quad shield RG6 & f connectors. I turned the gain down to minimun, same result scanning & at the moment, the masthead amp is bypassed completely with the same result. All channels accept 7 & local 10 are there reliably.

gibgib Posted October 21, 2007 Author Share Posted October 21, 2007 This script will save somebody living on the Sunshine coast a lot of time if they own a Dreambox with DVB/T (terrestrial) tuner. The basic correction ended up being the edit of the centre frequency for the local channels. This may also be a requirement for other regional areas. Simply add 100khz for the centre frequency in the script. What's a Dreambox? I've got the DM7025 which has 2 tuner capability, allowing Satellite, Terrestrial, & Cable in any combination. As it runs on Linux o/s it offers IDE interfacing, so a hard drive & DVD burner is also installed (option). It's also LAN connection so has the ability to stream to & from a PC! http://en.wikipedia.org/wiki/Dreambox <?xml version="1.0" encoding="iso-8859-1"?> <!-- useable flags are 1 -> Network Scan 2 -> use BAT 4 -> use ONIT 8 -> skip NITs of known networks and combinations of this.--> <locations> <terrestrial name="Sunshine Coast AU" flags="5"> <transponder centre_frequency="767625000" bandwidth="1" constellation="2" code_rate_hp="2" code_rate_lp="6" guard_interval="1" transmission_mode="1" hierarchy_information="0" inversion="2" /> <transponder centre_frequency="704600000" bandwidth="1" constellation="2" code_rate_hp="2" code_rate_lp="6" guard_interval="1" transmission_mode="1" hierarchy_information="0" inversion="2" /> <transponder centre_frequency="788600000" bandwidth="1" constellation="2" code_rate_hp="2" code_rate_lp="6" guard_interval="1" transmission_mode="1" hierarchy_information="0" inversion="2" /> <transponder centre_frequency="746500000" bandwidth="1" constellation="2" code_rate_hp="2" code_rate_lp="6" guard_interval="1" transmission_mode="1" hierarchy_information="0" inversion="2" /> <transponder centre_frequency="809500000" bandwidth="1" constellation="2" code_rate_hp="2" code_rate_lp="6" guard_interval="1" transmission_mode="1" hierarchy_information="0" inversion="2" /> <transponder centre_frequency="725500000" bandwidth="1" constellation="2" code_rate_hp="2" code_rate_lp="6" guard_interval="1" transmission_mode="1" hierarchy_information="0" inversion="2" /> <transponder centre_frequency="662600000" bandwidth="1" constellation="2" code_rate_hp="2" code_rate_lp="6" guard_interval="1" transmission_mode="1" hierarchy_information="0" inversion="2" /> <transponder centre_frequency="585625000" bandwidth="1" constellation="2" code_rate_hp="1" code_rate_lp="6" guard_interval="2" transmission_mode="1" hierarchy_information="0" inversion="2" /> </terrestrial> </locations> Link to comment Share on other sites More sharing options...
