This would  make a  good  test  for the   Op4H  ( 4 hour)  mode  and  the  correlation   detector ?

 

To date  there  have been  no  'dx' test , with the  addition  of  the  correlation  ,then  that  should give  three   possible detections  ?

 

OP4H decode ,  qrss plot  and  Correlation    ( and  50%  saving on power hihi)

 

OP4H has AFC  as the  shorter  modes and  is  designed for  normal sound card  use. with  sound-card  audio or  CW-comport Tx keying , rx  audio is  direct  in from  sound  card  , in short range  tests  -50 db s/n  has been reached , but  that  is a data  decode , would the  correlation , take the  level  below the  qrss  plot ?
