DK8KW Longwave Information
Stations I heard or worked on LF (in JO52BH)
and Stations that heard or saw me

Here is a list of stations I heard, saw on Spectrogram or worked so far on the European long-wave band between 135.7 and 137.8 kHz (click on the callsign to see the corresponding Spectrogram) or of those stations, that heard or saw my signal. Here is a map of squares worked:

Footnotes:
 

(*1): I started the measurements with my new antenna configuration. As a reference: the signal stregnth of DCF39 is -23 dBu (85 dBµV/m) here (0 dBu=0.775 V at 75 Ohm). For conversion of dBu to dBµV/m for my receiving setup, have a look here. With my current umbrella antenna, 0 dBu on 136 kHz equals to 108 dBµV/m, 0 dBu on 73 kHz equals to 125 dBµV/m.

(*2) Slow CW can be very relaxing:
