Uwe,

sorry, nothin= g was seen or detected here from your transmission today=2E Not a trace=2E Der erste Versuch ist meist nicht genuch (Didi Drahtlos)=2E

Yes I noticed= the good trace on Paul Nicholson's spectrogram http://abelian=2Eorg/vlf= /fbins=2Eshtml#p=3D1388246400&b=3D080&s=3Dsp=2E Just look a= t it the other way round: You did send a long carrier, only with some short interruptions=2E But the gaps= were so short that the spectrum didn't notice them ;-) 
 =
More seriousl= y: Compared= to a continuous carrier, with 50% duty cycle the carrier component is still there but 6 db down (half= average voltage)=2E In terms of power, on average you are spending 50% of the power=2E 25% (-6 dB) goes to the central carrier, and th= e other 25% into the AM sidebands carrying the message=2E   &= nbsp;
 =
What I find&n= bsp;strange is that the spectrogram trace seems to have jumped 28 mHz low, once near the beginning and again for an hour around 14:30=2E Are = you sure that your samplerate correction had been engaged without interruption?
