Hi Minto, Roelof, Stefan es others, The difference between DCF39 and the noise floor on a quiet day is 92 dB in 1 Hz (JO33DE) Antenna "inv L" 18m V and 34m H 73, Albert
Hello Albert, That's quite good. Today it is just 50 dB in 1 Hz here. I have extended my wideband screen to display DCF39 and HGA22, bottom of http://www.iup.uni-heidelberg.de/schaefer_vlf/DK7FC_LF_D
