Phase 2 of the Hannington transmitter switchover has been done, and there are no longer any analogue TV signals transmitted, so except for one MUX, all the others have changed frequencies and where I live I can now watch Freeview HD. I have had a previous post about the changes that need to be made if, like me, you get some of your TV services via a Linux computer using TVHeadend, MythTV or similar.
The following is what should be in an updated /usr/share/dvb/dvb-t/uk-Hannington file:
# UK, Hannington # T freq bw fec_hi fec_lo mod transmission-mode guard-interval hierarchy T 666000000 8MHz 2/3 NONE QAM64 8k 1/32 NONE # BBCA MUX T 642000000 8MHz 2/3 NONE QAM64 8k 1/32 NONE # D3+4 MUX T 618167000 8MHz 2/3 NONE QAM256 32k 1/128 NONE # BBCB MUX (DVB-T2, HD channels) T 634000000 8MHz 3/4 NONE QAM64 8k 1/32 NONE # SDN MUX, not sure if fec_hi should be 2/3 T 658000000 8MHz 3/4 NONE QAM64 8k 1/32 NONE # ArqA MUX, not sure if fec_hi should be 2/3 T 682000000 8MHz 3/4 NONE QAM64 8k 1/32 NONE # ArqB MUX
If, like me, you use tvheadend, you will need to create all the Multiplexes manually. Using the data above, this is what you will need to enter:
Frequency (kHz): <field 2 if you count the first ‘T’ as field 1, remove the last three zero’s>
Bandwidth: 8 MHz
Constellation: <field 6>
Transmission mode: <field 7>
Guard interval: <field 8>
Hierarchy: None
FEC Hi: <field 4>
FEC Lo: <AUTO or NONE, not quite sure, I entered AUTO and it works here>
These data have been valid since February 22, and I have no information about when or if they might change. In April some of the multiplexes will have their transmitting power increased, but this will not require any changes to the above.
