Hi Markus=2C

Thanks for the se= rvice.
Last =0A= night i tried again but there is no chance. It appears that the DCF39 SNR i= s =0A= much lower than expected over that distance. Are you sure this is due to th= e =0A= hill on the path to DCF?
Do you think you can see the band noise / have = the =0A= maximum sensitivity? I assume there could be at least 10 dB=2C rather 20 dB= to =0A= gain. How does the diurnal wideband spectrum look there? Periodic QRM?
