oh look - Opera has picked up Deep Search!
 
I'm a bit surprised, and also a bit amused...

Some points Mike

200%F  is  a  bodge to get the  text  beacon via   the  server , not
showing  in my  latest  spot listing ?

There  are now  two  entirely  different  systems  packaged  in the  one
application ,  the  original Opera  data  mode , which is   capable  of
presenting  the  fade pattern  and  the  s/n ,  the  other  relies  on  call
matching  and  presents  s/n only  , hence  the  'odd' 200%F  , the  dynamic
search has been trailed  on  normal  'ham' kit and  provides an extension to
the  existing  system .

Before  any  variations  are  attempted ,  off  air  stats  are needed ,
there  was  close  to  100  instances  of  V155  in use  since  its  launch
,  with  only  1 error  that  would be   1% . Occurrences  will  be
statistically  related to  user  numbers

Where  it  is  unfortunate   'real'  calls  are  produced  , the  time
delay  presents a  simple , at a glance spot-check , the integrity of the
original  system has not  been  compromised, at the  moment  the list
has a  8 day  life , this  could be  reduced , but  with the  7 day
operating
cycle ,  8  provides overlap
