I'm new to radio and I've just found this signal. There are a few similar other signals around this one.


Samples[edit]

Presumably in this frequency range it concerns services of the Hungarian railway. Digital train radio via radio relay system as well as signal control and commands for setting points. I found this "multiple transmissions" only near bigger train-stations.
