Today SV8RV did copy my 0.2mW signal in OP05 via QO100. Dish is 2 meter :-) 
It was not possible to become decoded with less power   [21/9/2019]

 

Peter, reports the  200 uW  carrier power  was measured at the  feed point  of his  2 meter  dish,  

[noting , that  in terms of  energy expended ,  power deployed  equates to  100 uW ]

SV8RV , taking  the signal off air  at 10GHz 

 

Quite outstanding  , taking the  frequency and path involved  , not to  mention the  AO100  sat !
In terms of actual power deployed,  due to the  50%  mark/space ratio , this equates to 100uW
- noting that  when the  TX is 'off;' power is no  being  supplied , so. only power  deployed is 
actually  used  . 

Test with  longer  timelines  , op1  are planned  soon,  all the band  decoders , benefited  from the  ea5dom
eme  tests ,  the  main concern ,being  the ability of the  AFC to  track the  signal ,  faster times are 'simpler'
seemingly .  over the  Sat , stability is  good, so , longer times should function ....

Spots in the  EA data base, show  a series  of  -20  /  -21  dB  spots  from  SV8
