Increasing power on Medium wave will not get the station a bigger audience. Expanding other platforms if the way forward. Medium wave is only to give the Anoraks something to talk about on forums like this one. If the station really needs to move on as some are suggesting, ending Medium wave like everybody else is doing would be logical. It's however there to appeal to the life long listeners who remember listening to the station most of their lives from the ship. A stronger signal on 648 won't suddenly get a massive new listener response. Those days ended back in the 1980's. It's just a bit of fun for the so called 'community of interest'.
