this is how it sounds like (ASCII-200 Bd) (rb, 2008)
look at the 3 EFR station
signals with their data telegrams on a spectrum receiver (rb,
2009)
here tuned to the hungarian signal from Lakihegy on nominal 135,6
kHz, with Mainflingen 129,1 to
the left and Burg 139 kHz to the
right
nice QSL-card from this station
