Thanks for the ID on that 8191.9 slow dasher -- yep, it's the 2nd harmonic of Coxie. Both were coming in well yesterday and I was able to view them side-by-side on separate waterfall displays (using KPH and KFS SDRs).
Besides the Marin Ditter and Coxie, it makes me wonder if any of the other ~8192 beacons are actually the 2nd harmonic of a 4 MHz beacon.
