Talk:Continuously signal on 424.493Mhz
I've been tracking this unknown mode for a few years, it appears during sporadic-e events in the summer mainly. It's also heard in and around Brussels. I have voice recordings taken from the adjacent voice channels which are 12.5khz away from the control channel.
Same in Ghent
In Ghent, Belgium same sound on 424.688. Indeed related to 'De Lijn' buscompany but not sure what it is.
