We hope that 1287 will give you better reception than you had before.

Largest Network of Commercial Radios Launched.
From September 2020, 49 of the 56 stations acquired in 2019 by the Bauer Group will change their name to Greatest Hits Radio, making the network the most important in the UK. Only four stations will retain their names under the Hits Radio brand: Pulse 1 in Bradford, Signal 1 in Stoke, The Wave 96.4 in Swansea and Fire Radio in Bournemouth. Three others will remain autonomous (Lincs FM in Lincoln, Pirate FM in Cornwall and Sam FM in Bristol). All the digital-only radio stations acquired last year (from UKRD, Lincs, Wireless and Celador) will be closed down. The closure of the local offices has resulted in staff cuts and protests from listeners as they had to say goodbye to their favourite presenters. 
Here are the details of the operation.
