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

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.
