Been told tonight the terrible audio is finally resolved and apparently they sound a thousand times better. ....And that the signal is stronger and they are broadcasting in Stereo now.
Yup, scrolling RDS: http://www.g33ky.xyz/basefm_rds.mp4. They weren't playing anything at the time so I can't comment on the audio quality. The Radiotext said "Base FM UK 87.7" (or something like that, I forgot to record it).
Good vid Lewis. Hopefully the guys behind the station stay on the air without much issue, good to have some actual variety of music up in Manchester rather than the standard CHR/AC garbage.
