Hi Graham
 
The answer is ... QRO :)
 
I'm running the 100w PA made by Fausto IK4NMF. Not big signal increase in local (7km) decodes but
clear difference at 300Km as seen by EB3FRN
 
After improving loop matching, PA works at full power. Fortunately Opera8 keeps the PA almost cold
while a single WSPR-2 period is a real stress test. Loop match is still far from perfect and stressing
full power modes are not wellcome with this setup 
 
As Stefan told, keeping the loop tuned is an endless task and not the way to go for QRO/Dx
Even worse for a flat horizontal loop like mine
 
Next in the list is going vertical. Coil and variometer on the way. Keep tuned ;-)

 Audacity  of it , in board daylight   as well
 
These are all  well  above the  Dynamic switch over level , Q question  for the  propagation dep't  , what's  changed ?
local decode  levels  still  -5/-6 dB  , but that  path is  upto  6 dB  less attenuation [ opera > dynamic  s/n still  average  and  same calibration]

Hi, Graham

copying to G6AVK too, with nice signals

23:05    477 G6AVK Op8 1503.9 Hz -25 dB Fade: 2%

I attach a pict from my grabber where can see EA5DOM and G6AVK at the same time

You catched me Graham ! ;-)

Running the horizontal loop again. Better matching to the PA than before, but only 8W now

I have continued Txing WSPR and Opera8 during daylight hours. Nothing on WSPR-2 at EB3FRN
but Opera is decodable at Deep Search. Turned on my monitor to confirm the spots and then
the Deep Search spots marked as "??" go without question marks

11:59    477 EA5DOM de EB3FRN Op8 Deep Search ?? -35 dB in MONTBRIO 1488.8 Hz

Big difference over WSPR-2 and even taking in consideration the higer QRM at EB3FRN
during daylight hours

Jump in Opera activity to  day ,  with excellent conditions on   14 MHz  UK/EU<>VK  


LF/MF - Note the  PSK map  ONLY shows  opera  data  decodes , Dynamic spots are  routed via the  Opera APP 


Good demonstration of running a local ' Rx  on LF and MF  by EA5DOM , only reaching EB3FRN in Dynamic , but validated by the local off air time stamp and recovered average frequency , within 200 mHz , -36 dB is about the  lower limit for  op8D
