The existing Scottish AM stations (Clyde 2, Forth 2, Tay 2 etc) are being replaced with Greatest Hits Radio which already exists in England and Wales.
There has been no mention of any AM TX closures in Scotland as yet.
The local ex ILR MW stations, eg 1170 1170 1278 1530 (which used to carry GHR) are now running re-tune loops.
