The service began in 2007 as 'Nowodhow an Seythun' (News of the Week). This was a short 4 minute podcast, distributed each week through a collection of Cornish cultural websites. This service was increased to half an hour each week in 2008, meanwhile adopting the new name. The format changed at this point to become a magazine programme, incorporating music, discussion and news. In 2010, Radyo an Gernewegva incorporated the original 'Nowodhow an Seythun' back into the service. In 2013 it was shortlisted for Radio Station of the Year at the Celtic Media Festival. In the same year a crowdfunding campaign was launched to raise funds for a new website. The campaign was successful raising over £5,000. Listening to Radyo an Gernewegva is suggested as an aid to learning Cornish for the Say Something in Cornish course. It attracts more than 500 listeners every week.
