The unknown ..
 
The  stand alone  Opera  APP  is   responsible   for the  off  air  detection  ,  the  web linking   distributes  the  spots  to  other  users  and  the  psk-map 
 
With the  introduction  of the  dynamic  option ,  web data  is  used  to  populate  the  search  lists  from Tx beacons  and   x 2   same call  decodes  the  detection/decode  time  stamps ,  originated  by  the   Tx/Rx  stations , which  all ways   existed , are now  being  utilised  to  test  for  time  windows 
 
Worst  case  are  loan wolf  Tx  and  Rx  , then its  down to   time  alone to  validate  the  deep-search  ,  
 opera  normal  is a  data  Tx  so  extracts  the  call  from the  Tx  ,  false  decodes    have  real  call  formats  with  random  values  , false  detections  have  real calls  but  random   time  stamps  ,
 
eg  vo1na  > ku4xr last night ,  from the  data  base 1 spot  can be  seen  to  be  false ,  others  are  validated  by  UK   decodes  , the  later  G8HUH   spots  would  need  access  to the  TX end  times  to  evaluate ,  qsb  bringing  opera  into  range  at  times  ,  handy  as  a time  stamp  for  no  web linked  Tx stations

Hi Graham,

Thanks for clarification.

Well  Wolf ,  there  is a good  paper trail  in the  system  for  this  one ..  
 
The  system  history  shows  ,  GM4 and  VK spots are  time  stamped   less than 8 seconds difference, so  validated  the  spot
also  VK shows  no decodes  or  detections  in the  previous  24 Hours  or  since , opera has a  very low  false  detection  level  
Ok, I would be convinced if Opera didn't exchange so much information about who actually transmits, and where, and when, over the internet.. I wouldn't say it's impossible to that this """decode""" is real, but I wouldn't call these  """decodes""" from this "closed source black box named Opera" too reliable.
