Graham;
Temps here went from 8F to 40 yesterday and last night.  No doubt had something to do with poor condx.  Soil conductivity in this region of NY state is sensitive to temp.  Soil conductivity drops drastically with warmer above freezing temps-Bob

Bob,all

 

Results from the  psk-map

 

73,G,

 

Only decode   one showing ?  but  there  is a data  set , unless  the  Tx  power increased by   8 dB and  fell  back  , that looks like  the  path  is  variable  ?

 

What  was the  Fade % ?

 

If  the   software / audio  drive  is not  being  used  , may be keep with carrier frequency and let the  Rx stations make the 

calculations ! noting . narrow filtering  will  'degrade' the  min recoverable   s/n 

 

 

WH1XBA

AC4IU

OPERA

Fade over the  300 mile path ? the  s/n  levels  are the  average  over the

2 Hour  tx period
