Hi VLF,

Along with some carrier transmissions i run some good old DFCW-90 on my 900m ground loop. At 1.8 A antenna current i easyly saw the signal in a QRSS/DFCW-60 spectrogram (22 mHz, 10 sec scroll rate), spectrogram attached. Like on LF, the QRN increased at midday. For this frequency it is a distance of > 1 wavelength. A short carrier transmission running earlier showed 28.5 dB S/N in 2.8 mHz.
73, Stefan
