Freeview on the Wenvoe transmitter

You may not be able to receive all the Freeview channels

Some channels on the Wenvoe 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.

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
ABERGWESYN	AD	7 km N Llanwrtyd Wells	20 homes
BARRY	T	10 km SW city centre	300 homes
CELTIC MANOR	T	5 km E Newport	80 homes
PENTREBACH	T	3 km S Merthyr Tydfil	100 homes

Notes

'Out of group' frequencies are marked with a star. Analogue power output 500,000 Watts, post switchover average digital multiplex output will be 56,250 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.

* The Wenvoe transmitter was not an original ITV VHF 405-line transmitter: the historical information shown above includes the details of the company reponsible for the Wenvoe transmitter when it began transmission.

405-line VHF black and white TV

From the Wenvoe transmitter, BBC One was broadcast on VHF C5. In the United Kingdom, 405-line television was used from 1936-39 and 1946 until 1982-85.
