Beginning during 2015's JAMARTIS Summer Programme, a mobile radio broadcast and narrowcast has been developed by Studio 174. The first broadcasts took place in Bloxburgh, a village community on the Blue Mountain who have been campaigning for 15 years to restore running water and  road networks, destroyed by hurricane damage, to their community.

The weekly broadcasts throughout June 2015, facilitated by JAMARTIS participants and Radio Sonar founder Anton Kats, combined performance, documentary, audience interaction and studio phone ins to provide a platform and a framework for the community's activism and organisation. Summer 2016 will see a permanent station established in the disused primary school in Bloxburgh which has stood empty since being closed in 2013 as the population began to leave the village. The school's position, overlooking much of the surrounding region makes it an ideal location for a radio station, allowing many nearby villages and communities to engage and interact with  Bloxburgh and its campaigns.

Back in Kingston, JAMARTIS participants used the weekly radio format as a platform through which they would present their latest work and experiences to an audience within a 5 mile radius. Guests from the communities with which participants were working, including fishermen, musicians, students and divers would be invited onto the show every Thursday to offer their perspectives on the work and the wider issues in Downtown.
