The Hungarian "DCF" station has been putting audible sidebands into the lower end of the band for some time, but this is the first time I have noticed audible sidebands of the data bursts at the upper end of the band as well! Cheers, Jim Moritz 73 de M0BMU ...My unconfirmed assumption is that the modulation parameters of DCF39 have been changed towards even less pulse shaping. But an occupied bandwidth of 3.8 kHz for a 200 bd FSK signal would seem rather ridiculous! I would be keen to know whether others are also seeing the annoying sidebands, and if anyone in the group has contact information to the DCF transmitter operators on site. 73 and Happy Easter, Markus, DF6NM
