Topband: Possible 160m propagation indicator: lightningmaps.org?

[DXer]

Mike,

Thank you for the post, very timely for me.

I have been exploring the VLF and LF spectrum (RX only) for a few weeks 
now, after spending some time and money acquiring the capability.

As far as hamradio goes, there is life in the 2200 and 600M bands.

Regarding lightning strikes and their effects, yesterday was an 
interesting day. Keeping in mind this is all news to me, I was surprised 
to see the number of 'hits' on my SDR waterfall. It was like every 10-15 
seconds or so. The SDR would go into clipping for the duration.

This went on for a few hours, nothing was being decoded, and then quiet. 
G0MRF in the UK, and other NA stations, showed up again on the monitor a 
few minutes later on 600M. I did not check 160M, will do next time.

I did not see any mention of yesterday's condition on the VLF list 
though. There are ongoing attempts on 8.270 kHz and less frequently on 
1.65 kHz. Fascinating stuff.

Thank you for the links.
