ARLA/CLUSTER: Futuro uso dos 648 kHz (Onda Media) no Reino Unido

[João Gonçalves Costa]

Future use of 648 kHz medium wave

Ofcom has varied the Wireless Telegraphy Act issued to Babcock Communications Ltd, which covers a number of different analogue radio frequencies, to remove Babcock's authorisation to use the 648 kHz frequency previously used to broadcast the BBC World Service

The licence was varied by Ofcom because the authority conferred by the licence to use the 648 kHz frequency was for certain purposes only, which have now fallen away.

Subject to international co-ordination, this frequency will now be available for use by community radio licensing in various parts of the UK, in addition to FM and other AM frequencies that are already potentially available for this purpose. However, we note that the characteristics of 648 kHz, being at the lower end of the AM band and therefore requiring relatively large masts and transmitter sites, may make it less suitable for community radio than other AM frequencies.
