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 ?

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
