Ah yes, now I remember hearing that name. Thank you, Simon Those are
the sweeping beacons I mentioned.

Google on 'chirpsounder' and you'll find a strange world of
propagation analysis stuff you may not have known about or imagined.
Peter Martinez G3PLX, one of ham radio's resident geniuses (inventor
of PSK), seems to have started the ball rolling with a software app
and analytical framework. Others have built on it to create a number
of esoteric tools to figure out what's going on up there in the sky.

Of course, what Jim was hearing that prompted all this may be
something different, like a faulty cable repeater, and may have
nothing to do with chirpsounders. But some of the ones I hear
definitely are.
