Dang, was trolling through the Auroral Chorus site again and saw that I had overlooked the beacon called Haystack:
"HAYSTACK bcn runs 3 sec dash on 4096.35 kHz 24/7 late 2015".
http://www.auroralchorus.com/4096khz3.htmThat must be what I thought was Hexie (which is a shorter dash).
So a summary from their web site:
4095.900 KHz Coxie, 4 sec dash, day only
4095.940 KHz Viking, 3.3 sec dash, 24/7
4096.240 KHz Hexie, 1 sec dash, 24/7
4096.350 KHz Haystack, 3 sec dash, 24/7
4097.250 KHz Inyo Whooper, day only
Right now on my waterfall display I can see both Viking and Haystack. It is just possible that Hexie is coming up out of the noise every so often but I think I see a good trace on the Waterfall display.
