Waltham retune - 12 October 2011
Waltham transmitter – retune required on or after 12 October 2011
On 12 October 2011 the SDN multiplex from the Waltham transmitter is changing transmission mode from 2K COFDM to 8K COFDM and increasing in power. To continue to receive these services, some DTT viewers (depending on the receiving equipment) may need to retune on or after completion of the work, scheduled to be finished by 6am.
Freeview TVs, Freeview boxes and recorders will need to be retuned. BT Vision and Top Up TV boxes (which use the Freeview signal) will also need retuning.
Viewers should perform a full retune (sometimes called “Factory settings”, “Default settings” or “Shipping conditions”) rather than “Add channels”.
Analogue TVs, satellite and cable services do not need to be retuned.
Note: Switchover at these transmitters completed in August 2011.
