Thanks  for  that  Markus
 
That  info  could be  gathered at the  RX   stations  and  shared  via the  web  beacon , but  would  only  be of  use  is the  'audio'   tx  drive  was  used  ..
 
For  such a short  tx time   , 4 mins  of  'carrier'  and  anything  over  2  mins  needed  for  a  decode  , OP8  seems  to  be  producing  some  very  good  results , unless  there  is  some  'flutter'   , which the  shorter  cycle  is able  to  make  use of ?  if nothing  else  , the  power bill  is  25% of  op32  !
 
W1VD is  also  showing  on the  PSK map  ,   Gus is  running  higher  power  than  at the  start , so  may be  W1VD is  in range  ?

Yes op-8 would have been in easy reach. This morning, Joe's dashes were well discernible even in the 0.7 Hz grabber window.
 
Having said that, my personal preference regarding overnight beaconing is more towards "the slower the better" ;-) In the morning I'd rather be greeted by 10 really deep detections than by a long list of spots with intermediate sensitivity.
 
As for frequency, using 137650 exactly might not be ideal, as observers in East Europe would likely be affected by the Russian Loran / Chayka chain. Actually here in Central Europe the 6.25 Hz multiples reappeared today when Slonim (the most westerly station in the chain) came back on air after several weeks outage. Staying away from the Loran lines by a Hz or so will avoid that problem.

Joe,

Looking  at the  psk-map  , Its  quite possible  , all the  monitors  where
looking  for  OP8   signals   ve7bdq  <> we2xpq   is also  showing as  OP8
as well

No reason  why OP8 should not  decode  from  you  ,  just  need  to   qsy
to  the  OP8 centre   qrg   137.650 KHz
