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

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

2 Hour  tx period
