Hi All,
Something came up on one of my radio monitors today, not the usual kind of signal I receive, but I thought I'd post anyway and hope it doesn't drop me on my a... like the last one. It was recorded on a 24/7 system, and I've changed my usual monitoring range in favour of the lower frequency scale, this does tend to pick up more man made disruption, but has the advantage of identifying weaker signals of the nature required.
I've also opted to post images rather than descriptive text, and hopefully you'll find them a little more ledgeble.
The image here shows a disruption in the noise line starting at 12:30 UT (21/8/15), so I guess my 48 hour prediction starts here. The noise line covers all frequencies between 8,000 Hz and 20,000 Hz, any significant EM disruption will encroach into this region.
This is the same image as before, but I've overlayed the 300 Hz (Fawn) and 26,000 Hz (White) traces to show the signal came in at 0, and after a short warning, increased in intensity beyond the white trace.
This final image is the unprocessed version, and gives you the true scale of what appears to be a short, sharp electromagnetic surge. As always, I've checked the usual variables and come up short, unfarmiliarity makes it hard to predict magnitude (assuming this is a quake!), but a close 5.5+ or a distant 6 would be an interesting outcome.
Duffy,
