At 90 watts  , RN7T , decoding  into  UK at the  moment  , improved   east-west  over the  last  week ?

On the  s/n front ,  Op or  wspr  is giving  a  path  quality indication  , which  takes into  account  ,rx  conditions , local urban noise unfortunately  can vary  considerably  , at  my  qth  , it can make  over  10 dB difference to the  decode  s/n  , or  stop  it  all  together  
 
In a fixed  system the  audio  level indication  , would be a measurement  of  wide band  noise in the  2.5k pass  band , that  may be a  route ?
