Three new transmitters will give BBC Radio Scotland extra coverage on the A9 between Inverness and Perth.
Until now, the area has been a radio blackspot, but that is set to change with new sites at Crubenmore, Dalnacardoch Wood and Blair Atholl.
The 60 miles of radio silence had been raised with the BBC by the Audience Council for Scotland, whose members were contacted by licence fee payers concerned about failure to get up-to-the-minute travel and weather bulletins, in particular, on a road regularly hit by snow and ice.
Over the years, several solutions have been explored but the topography and isolated nature of the area has made it difficult to find any plans which were viable.
Now the BBC's transmission provider will carry out work at three towers over the next few months to bring the transmitters on-air. That should ensure that BBC Radio Scotland will be available by the end of the summer via a combination of MW and FM between Perth and Inverness.
Jeff Zycinski, Head of Radio, BBC Scotland, welcomed the development: "These transmission blackspots have been of great concern to our listeners for many years and I know they will welcome this solution.
"The route through Highland Perthshire and into Inverness is one of the busiest in Scotland and the severe conditions this past winter remind us how important is that travellers have access to the latest news and information from BBC Radio Scotland.
"As someone who now lives and work in Inverness, I know how frustrating it can be to encounter those patches of radio silence or poor reception and I'm so pleased that my colleagues have come up with a way to sort that – despite some of the technical problems presented by the geography and the terrain."
