This signal at the lower band edge can be used as a propagation indicator for longwave propagation into Southern Europe.
Mark: 135.870 kHz
Space: 135.775 kHz
Shift: 95 Hz
Baudrate: 75 baud (?) FSK
Signal strength: normally up to approx. -104 dBu (at 75 Ohm), raises up to -88 dBu (75) when conditions are good to Southern Europe (correlation with stations from IK5)
