FB, Stef,
 
Will  tune to 477k   now ,only  a  few  hours of  day light  , signals should  start to  show  qsb  soon  as the  skip  starts , will  leave the  Rx on  477  to  may be  2300 gmt     2400 local  time ..
 
Still   same  s/n  from  >> 18:44 500 DK8KW Op4 -29 dB

OK. Give me some time, i will consider...
Still no signal in Delft. Seems they use a band filter centered arround 505 kHz. Maybe i'm some dB down there...

OK  Stefan,
 
well   all  you  need  is to   send  carrier  on   ( 477KHz  + 1700 Hz)  =    478.700 KHz  , use  Opera  set to  500KHz   OP4  mode Tx   and  after  4 mins ,  you will  have  a  s/n report  from  all  tuned to  477 KHz  : )
 

17:53 500 DK8KW Op4 -29 dB

Well, these are my very first tests. The PA has a CW key input now, works excellent. I think i will start with some carriers and a bit CW.
Last night i've finished to build my MF RX and a active antenna. First tests look promising but i still haven't heared or seen amateur signals. It's slowly starting here now.
I've just sent a carrier on 478 kHz but saw/heared nothing in Delft... I still have no idea about MF propagation...
Exciting! :-)

Ok Stefan ,
 
What mode  are  sending  ? opera ?  If  so  then   I will   set the  RX to  477  as  well  , Im sure  some  signal  will  leak   directly into  io83lk  hihi

Thank you Graham, eh i mean G..,

Most useful link! I forgot about it. Maybe its worth to ask the OM to extend the range...

Expect to hear my signal there in an hour or so.

Something just  noticed , 477 is  inside the  Delft-web-sdr range .... !
 
Monitoring   500K  off  air  and  477  via  Delft
 
can  run x2 sdr  and  monitor  500/477  , but  with  x 2 noise .should  work  ?
