Radio Bronglais applied to the National Lottery Charity Board of Wales, and in the spring of 1999 were awarded £117,455.

2012 saw the station increase its power output after a successful application to Ofcom, and now broadcasts to a wider audience.

In 2013 Radio Bronglais changed its name to RB FM and launched webcams from the studio during live shows.

The station is run by a dedicated committee, volunteer presenters, librarians, administrators, fundraisers and technical staff.

On 11 April 2014, Radio Bronglais's volunteers completed a 24-hour broadcast, with guests including Walter Coenig and Wincey Willis.
