Mountain rescue teams have welcomed an investment of about £300,000 in updating their radio equipment.
The cost of replacing equipment is being examined
The Mountain Rescue Committee of Scotland has already raised about £200,000 towards the cost.
Now the Scottish Executive has said it will provide about £300,000 towards the scheme.
First Minister Jack McConnell said: "These men and women are prepared to risk their own lives to rescue walkers and climbers who are lost or injured.
"It's vital that these teams have access to modern equipment and that's why we have committed to providing funding to help ensure that this modernisation project can go ahead."
A study examining the cost of replacing the radio equipment, which is nearing the end of its usable life, is expected to be completed this summer.
There are more pressures on mountain rescue teams because of changes in legislation and getting funds is more of a struggle

The precise amount of the executive's funding will be decided once the full costs become clear.
Miller Harris, secretary of Lochaber Mountain Rescue Team, said: "This funding is a welcome step and welcome recognition from the Scottish Executive about the importance of mountain rescue.
"There are more pressures on mountain rescue teams because of changes in legislation and getting funds is more of a struggle."
Mr McConnell made the announcement during a visit to the Cairngorms Ski Centre near Aviemore.
He also reminded people to take simple precautions on the hills, making sure that they take into account weather conditions and dress properly.
"While it may feel like spring is in the air, Scotland's hills and mountains are still in full winter condition at present and likely to
remain so throughout March and April," he said.
