Interleaved Frequencies maps (old ones)
These are the maps, supplied by Ofcom, showing the coverage areas for the "Interleaved Frequencies" than can be used for the Freeview Local TV service.
The green areas have good predicted coverage for the "Interleaved Frequencies", yellow is possible coverage.
Note: these areas are considerably different from the normal Freeview coverage for each transmitter.
Update: Ofcom introductory comments
The study considered frequency channels -5 below and +2 above the receive aerial group for the station. Though for the 10 largest stations all channels were considered.
The ERP of main stations has been set at 10kW and relay stations at 1kW. It should be noted that in several cases these powers result in a higher ERP than allocated to the main multiplexes.
Coverage of the chosen channel has been assessed on the basis of the derived template and the use of a 64QAM 2/3 modulation scheme. Availability of mast aperture, mast loading and building space to support the required antennas and house transmitters was not investigated.
Coverage calculations are based on existing broadcast stations and reception via fixed roof top aerials.
The derived UK median templates are designed to protect populated coverage derived by the median method. The derived UK continental templates include Irish and Continental restrictions based on 23dB?V/m at the border.
The exercise has been based on version 5.51 of the UK digital plan and an interpretation of the GE-06 frequency plan for Europe. Coverage of each interleaved channel is quoted in isolation, i.e. only that channel and the v5.5 plan have been considered.
As coverage is based on the template at the planned height and at the maximum ERP, coverage using implemented antennas, heights and actual ERP will be lower.
The Interleaved Map for the transmitter is created from three elements. The left circular image shows the UK post-switchover use of the same frequency, the central circular image is the Continental use of the same frequency. These are subtracted from the "normal" coverage area for the transmitter, the right hand image, to create the "Interleaved Frequency" coverage area.

thanks for prompt reply.
i'm trying to pre-config Kaffeine Player in PCLinuxOS - for the two muxes that have too weak a signal here to locate automatically.
They're Hauppage cards that get an initial config file from Germany - but its not fully up to date.
I'll keep trying and maybe install XBMC or MythTV.
Still curious to where that ID info could be found.
