Is it just me, or is the new modulation on DCF39 and its companion 
just below the 136kHz amateur band much too wide?

Not only is the band wiped out during the data bursts but I can see 
traces of them above 200kHz! I have attenuated my input and see no 
reduction, so I am assuming my receiver is OK? Of course, I could 
have a bad joint on the antenna. Does anyone else see this very wide 
splatter?
