Thanks Graham,

Just getting ready to switch on the TX at 0000 utc... a bit late tonight.

Hi Graham and Markus,

It's a relief to learn that the TX has drifted off QRG! Thanks Markus.
Will continue with OP32 tonight.

Graham, to make OP8 from 32, just divide by 4, right?  (8192/4 ms pulses)
And will it be OK to stay on 137.555 as 650 seems a bit congested?

73 to all
Joe

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 ?

73-G,

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.

Best 73,
Markus (DF6NM)

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

73 -G,
