April 18th - retune at Rowridge, Oxford, Stockland Hill and Hannington
Brian Butterworth published on UK Free TV If you use the Rowridge transmitter, you will need to retune today as the commercial multiplexes have changed frequencies today to their final allocation.
SDN is now on C25 (506.0MHz), ArqA on C22+ (482.2MHz) and C28 (530.0MHz).
In addition, the commercial multiplex are now being broadcast at full power (200kW) with vertical polarization (the elements on the receiving aerial going up and down) and at 50kW with horizontal polarization. This means that for some viewers, it may be possible to improve their Freeview signal quality by rotating their aerial.
It is necessary, once again, to perform a "first time install" on your Freeview equipment if you use Rowridge.
At Stockland Hill, the commercial multiplex increase in power from 10kW to 25kW today. If you could not receive the SDN, ArqA and ArqB multiplexes from the transmitter before today, you should retune your Freeview equipment to see if you now can receive the services.
At the Oxford transmitter, the commercial multiplex increase in power from 12.5kW to their final level of 50kW today. Again, if you could not receive the SDN, ArqA and ArqB multiplexes from the transmitter before today, you should retune your Freeview equipment to see if you now can receive the services.
And the same applies for the Hannington transmitter, where the levels increase to 25kW today. So, if you could not receive the SDN, ArqA and ArqB multiplexes from the transmitter before today, you should retune your Freeview equipment to see if you now can receive the services.
Ted: You asked about switching your aerial to vertical. It depends on which transmitter you are using (with the exception of a few that transmit horizontally and vertically).
If you ask the question because everyone else's aerials are vertical, then they may be on a relay transmitter that doesn't carry the Commercial multiplexes.
