Dear LF Group,

After some months of exile from amateur radio in order to finish some
work-related projects, I monitored the transatlantic segment of 136k last
night, and saw XES, XKO and NA at fluctuating levels throughout the night,
with best signals around dawn (see attachment). Whose is the "sawtooth"
faintly visible at the bottom of the screen?

Cheers, Jim Moritz
