Freeview on the Moel-Y-Parc transmitter

You may not be able to receive all the Freeview channels

Some channels on the Moel-Y-Parc transmitter have lower transmission power so you may receive only some of them.

Your cables, connectors and aerial may need upgrading to get all the Freeview channels.

If you are missing your electronic programme guide (EPG), your channel line-up is wrong or incomplete, you have no subtitles or the 'press red' services do not work, please try this reset procedure first.

Mux is an abbreviation of multiplex. The Effective power level takes into account the transmission mode - and does not indicate a fault condition.

To receive Freeview from the Moel-Y-Parc transmitter you will require an aerial of group W (or wideband) positioned horizontally. This transmitter is 551 metres above sea-level, and transmits at 416 watts.

Self-help relays

Self-help relays are transmitters that are not owned by the broadcasting and transmission companies, but by the local users. An active deflector (AD) re-transmits the analogue broadcasts on the same frequencies as the original broadcasts, while a transposer (T) transmits the received broadcasts on different frequencies.

Relay name	Type	Location	Notes

LLANDEGLA	T	12 km E Wrexham	33 homes

Notes

'Out of group' frequencies are marked with a star. Analogue power output 100,000 Watts, post switchover average digital multiplex output will be 12,857 Watts.

To receive signals from this transmitter, the aerial must be mounted for horizontal polarization - the elements going from left to right.

Before switchover, the public service broadcasting multiplexes were 1, 2 and B; afterwards they were first PSB1, 2 and 3 but now called BBCA, D3+4 and BBCB. The commercial multiplexes A, C and D had initial post-switchover names COM4, 5 and 6; now they are SDN, ArqA and ArqB. At switchover BBCA, ArqA and ArqB will switch from 16QAM to 64QAM mode transmission, so five multiplexes will transmit in the 64QAM (2/3) 8k mode. BBCB is used for Freeview HD (DVB-T2, 256QAM), and has a pre-switchover service on selected main transmitters.

Upgrade to Wideband aerial requried to watch all Freeview channels during dual running of analogue and digital television. After switchover, you will have needed to upgrade to a Wideband aerial to receive some or all digital television services.

405-line VHF black and white TV

From the Moel-Y-Parc transmitter, BBC One was broadcast on VHF C6. ITV was broadcast on VHF C11. In the United Kingdom, 405-line television was used from 1936-39 and 1946 until 1982-85.
