Ok  Pete
 
I think  you  can  extract more  data , but  last  time  I  tried  , just  got a  empty  exel   sheet ..........  hopefully  when Op   mode  is  running  on the   new   fixed   VHF beacons , someone  will  take a look  , but  to  date  , nothing 
 
73-G..
 
PS...This  will  interest  you , there  is another   driver  etc  for the  dongle   .may  be  better  than the  one we are  using   .....

May be  only   2  stations   have  decodes  ,  ROS  activity  showing  over  EU area , so  band  was  open

Ok Stefan,
 
QRT  , next to  look at the  reports  , I think  tonight  , minimum   decode  levels  are very  close ,  the  longer  OP modes are much lower , but the  qsb on 500 tends to  prevent  gain being  made by  extended  times
 
Opera   was  designed to  be  sent  by a  normal   CW  Tx   , psk/fsk    has a  dB  advantage , but  not  all  stations  can send   fsk or  psk, , especially  on  136  .. Without the  racal  ma1723 , it  would  be  difficult to  use fsk or  psk  on  500  , ( not that  psk  is  any  use on 500  .. too  much  phase  shifting ) 
 
Not  sure on the  wspr  settings , I dont  think the  software  can  produce   12 Khz  ,   stations  use  ,pic-dds  , that  may  be a  way  ahead ?
 
But tonight , using the  m-delt4    sound  card , I found the    mixer  monitor  could  be  used to  combine  2  channels  , so  the  audio  quality  was much better  than  in the  past, with  no  IMP  showing  ...

Hi Graham, LF/MF,Nice setup to see which mode is "better". Rik/ON7YD has done some tests a few months ago i remember. Now you need many receiving stations who monitor these 2 modes to the same time as well.Compared to WSPR i clearly find Opera an advantage regarding the ease of keying the PA without the need of FSK.On LF i could run both modes since i have the IQ upconverter (can WSPR set to an output frequency of 12.5 kHz?? (to be mixed with 125 kHz)) but on MF i would need to extend my setup...I really would like to join in tonite but i can't :-(((73, GL, Stefan/DK7FCAm 13.07.2012 20:20, schrieb Graham:
