Aussie "woodpecker". ?

Drifter...

Dunno, but something has been making a racket across the bottom edge of
40m
for a couple of months now. It runs at random times and I have heard it
from
several locations separated by several hundred kilometres.
Damn nuisance if it is the OTHR, but then, it's only the CW segment of
40m.
Who will miss it? ;-)

I remember the Russian Woodpecker all too well. It would clobber a lump of
spectrum several hundred kHz wide and be S9 or greater for hours. It also
followed the propagation and was a nuisance from 40m to 10m. The Jindalee
OTHR has a different signature and keeps away from the various ham and
commercial frequencies, which is very considerate of them. I think the new
one has a much faster pulse rate than the old Russian one.
