Hi Marcin,
At the very moment on VLF..LF :

22.1 kHz GQD (Anthorn), strong,
23.4 kHz DHO, extremely strong (my "VLF neighbour", hi)
24.0 NAA Cutler, USA, about 40 dB weaker than DHO but very cleary visible,
25.2 NML La Moure, USA, about 10 dB weaker than NAA but still visible
around 30 kHz : hell of a noise from energy saving QRM generators,
37.5 kHz TFK from Iceland,  strong,
around 40 kHz : lots of noise again, almost masking NAU on 40.75 kHz,
45.9 NSY (US navy from Italy), very strong also,
51.95 GYW from Scotland,
53.4 TBG from Turkey with a RTTY-like sound (no MSK)

plus a few 'unidentified' signals which don't look like MSK .
73, Wolf .
