Here in my location (mo64rx) I have no DCF39 sigs at day time. It is not
audible and it is not visible by hamview. But at night time it is very
strong, somtimes audible (when there is no noises) and it's level seems
to be more then 30 dB over noise. So vasriations of signal level is more
then 30 dB. Signal is strongest about 30..60 min before sunrise.

Unfortunely my RX can recieve  135 - 139 kHz only. So I can't observe
beacons. But usualy at evening local time I see very strong and
stable carrier on 137.390 kHz (may be (???) it is mirror chanel 132.61 kHz
) wich is on/off iregulary. I do not know what is this. May be it is local
signal only.
