Douglas (IoM) digital switchover schedule

Note: This is the only schedule for digital switchover. Digital services cannot be introduced before the dates listed for "testing purposes" as they will generally use the same transmission frequencies as the services they replace. Another alternative, available today, is Freesat.

Notes

'Out of group' frequencies are marked with a star. Analogue power output 4 Watts, post switchover average digital multiplex output will be 1,000 Watts.

To receive signals from this transmitter, the aerial must be mounted for vertical polarization - the elements going from top to bottom.

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.

After switchover an existing group C/D aerial will provide all digital TV services.

405-line VHF black and white TV

From the Douglas (IoM) 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.
