On all wideband VLF grabbers, activity was visible on unusual frequencies
this afternoon (Jan 24th):
18.6 kHz, 15:55 to 16:08 UT: long dashes
15.7 kHz, 16:15 to 16:30 two dashes
13.0 kHz, 16:37 to 16:40 one dash
18.6 kHz, 17:03 to 17:07 multitone 25 Hz spaced
17.8 kHz, 19:42 to 20:10 two tone and MSK data (up to 1.5 kHz wide !)
Perhaps all of these were Tacamo related? Man how I'd love to have that
airborne antenna ;-)
Best 73,

And on Tuesday morning, an unstable carrier comes on 18.066kHz at around
10:40utc with a short burst of FSK at 10:49 and disappears shortly after;
At 10:40, another rough carrier at 18:791kHz. starts up.
At 10:53 another carrier comes onto 18:135, drifting slowly downward and can
be seen to be tuning up.
At 10:55 the rough carrier on 18:791 disappears.
And so on....
Interesting times.
