Andy is  running  20  watts  carrier  power to a  short  vertical  antenna  , with  extensive  top loading  and  ground  system  , the effective  power  dissipated  equates to  10  watts   due to  Opera  50% duty  cycle ,  not that the  power is  lost ,  , when the  TX is  OFF , its OFF , there  being  no  waste of power , simply  Opera  uses  manchester  coding to  provide  sync ,  and  single tone ASK , needing  no  additional  time locking .

Internet usage is  limited to  spot  distribution and  population of the   deep  search list , which is maintained via  local decode  and  the  web , 

the non-Ros  designed  correlation  systems  for  spotting  opera op8&op32 , provide  web -based  deep search call  lists , maintained by user's , 

Opera is  listed in ADIF ,  a non  deep search  spot is  a  true  data  decode

Hi all, and HNY:

I would rate last nights results as the best to date using OP -8 on 477 KHz. First time reception from Roelof - PA0RDT
17 receptions from Geof - G0LUJ with 7 full decodes. and 6 receptions from Mike - KB6WFC with 1 full decode.

73 and Best DX to all: 
Andy - KU4XR
