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
