- Johnny555 11y agoInterestingly, the article says that the signal was picked up by an amateur in North Cornwall (in the UK?) in 2013, but the video you linked to was posted in 2012 by a ham from Brazil.

- petecooper 11y ago>(in the UK?) Correct. I live near Bude, north Cornwall, UK and can confirm this. Local attractions include GCHQ Bude[1], TAT-3[2], TAT-14[3], CANTAT-1[4], Apollo[5], TAT-8[6], AC-2[7], EIG[8] and GLO-1[9]. Unrelated but relevant: Henry Bottinger, former AT&T big cheese and author of possibly the finest book I've read on getting your point across to an audience[10], lives a few hundred metres up the road from me. Nice guy, too.

- zatkin 11y agoDid you mean "Henry M. Boettinger"? http://techchannel.att.com/play-video.cfm/2011/2/14/AT&T-Archives-1976---To-Communicate-Is-The-Beginning http://techchannel.att.com/play-video.cfm/2011/2/14/AT&T-Arc...
- petecooper 11y agoYes, that's him. We occasionally chat about mundane things at the local store. Alzheimer's disease hasn't been kind, so he needs some friendly help and assistance from time to time.
- zatkin 11y agoThat's so sad, sorry to hear about that. :(
- bpye 11y agoStill seems strange to see somewhere so close to home mentioned here. Always feels like the middle of nowhere when I'm in the area.
- philiphodgen 11y agoBook ordered. Thanks for the suggestion. Out of print, so a second hand copy off Amazon had to suffice.
- petecooper 11y agoHappy to help. There was a period from ~2003-2008 when I was looking for _any_ copy of the book, 'new' copies were absurdly expensive and even the well-used versions were upwards of 40USD. Then I moved to Cornwall, met the guy and he gave me a copy from his stash.
- mstade 11y agoThat's a great combination of visualizations, looks kind of like a waterfall.
