Re: LF: DCF39 break

Hi Markus,

Oh, DCF39 even has a 100 kW transmitter. I thought it is 50 kW, as stated at http://www.qru.de/dcf39-beacon.html. Seems they have QROed. We should do the same! :-)

73, Stefan

Hi Mauro,

 

yes keep praying, we are all suffering...

 

The "brothers" of 138.83 are 135.43 and 128.93 kHz (idle mark carrier frequencies, nominal center 170 Hz up). Their purpose is described on the operator's hompage

 http://www.efr.de/en/CMS/Home.aspx

 

Unfortunately the density of data bursts has been increased again lately. In addition to the usual timestamps every 11 seconds, there are now often continuous blocks of telegrams lasting for an hour or more.

 

The FSK transmitter on 135.8 kHz is SXV (Greek Navy), not related to the EFR network.

 
Best 73,

Markus (DF6NM)

Finally my prayers were answered!
Thanks to the God of the RF!

73 de Mauro IK1WVQ, with his rx continuously intermodulated ...

P.S.: what kind of information carries this terrible transmitter (he 
and his brothers at 135.400 and 135.700) ????
