[2] A number of former Wave 105 presenters including Steve Power, Mark Collins, Tony Shepherd, Andy Jackson, Stuart McGinley, Gary Parker, Tim Allen, Selina Ross and Kate Weston can be heard on Nation Radio South.

[3] It was replaced by The Coast 106 on 30 October 2008, and while initial RAJAR results were encouraging with a healthy increase over those posted by Original, the weekly reach stagnated at around 115,000 by early 2011.

All prior presenters except Robin Caddy were removed from the station, which switched to a format also used by Celador's other Jack stations - a presenter-led breakfast show (hosted by Bam Bam),[5] a Saturday morning "World Of Sport" show presented by Robin Caddy and automated music interspersed with topical one-liners in between songs voiced by actor Paul Darrow at other times.

On 1 December 2019, Sam FM no longer shared programming with its sister stations in Bristol and Swindon and took the tagline The South's Greatest Hits.

The rest of the time it takes networked programming from Nation Radio UK with opt-outs for news, sport, travel and weather updates.
