Ok Markus
 
Seems  better  signals earlier  in the  night  over this path  ?
 
The  rf  bands  are listed  in the   windows   software , under the  Frequencies   tab  , the  two  bands  are  a  result  of separating  the  mode  speeds  with  dedicated   dsp  , this  reduces  the  cpu  load  and  minimises  the  false decode's   [ Tokyo  seems  to  be  the  worst qth  for  this  ?]  early  versions where  dual  mode  / auto  detect , but  cpu loading  was  [ for  some ] an  issue
 
For  LF  OP32  + OP8   MF    OP4  and  OP8  are available by  selection  [others  can be used , but  require tx/rx  alignment ]   to  data  OP8  remains  for the  most,   un-tested  on 500    
 
Note OP8  pass  band  is  100Hz   OP4  200Hz  , operation  mid  band  for  fixed  qrg  stations  is  optimal  , spacing  app   3 Hz  is  required 
 
Rf  carrier  for  OP4  and  OP8   on 477  are  :-
 
478-5 > 478-6     and   478-6 > 478-8 
 
Rf  carrier  for  OP4  and  OP8   on  500  are  :-
 
501-5 > 501-6   and  501-6 > 501-8

Thanks Graham, happy to see the decode.
 
Yes pskreporter has still expatriated me from Nuernberg to middle England (wondering if that would be for the better or worse ;-)) According to a wspr spot the other day it's more like 1272 km
 2012-11-08 23:56   DF6NM   0.475631   -5   0   JN59nj   1   SV2DCD   KN00pl   1272   137
 
I was on 478.670 kHz at the time but 'm still not quite clear about the (RF) frequency bands which are being monitored for different Opera speeds. On LF, I gather it's 137.5-137.6 for Op32 and 135.6-137.7 for Op8, but where would the faster modes 4 and 2 go? And which are the respective slots on MF 478.xx kHz?
 
Best 73, and a nice weekend to all,
 
Markus (DF6NM, JN59NJ)
