Yes  only  go's to  show  ,

One  Guy's  ''Pixel''  is  another's  ''Nibble''

- have to keep  in mid, Op is a  one-pass  data  mode , the decode over 
heads are significant compared to 'carrier detection' -

But as Stefan has commented , the  number  of  stations  active  on 136 
tx/rx  is  definitely  on the  increase, where  as the  PSK      map  used 
to  show the odd  red  spot , now its  quite  packed !
