Pure carrier doesn't have to be continuous, eg separate 10min
transmissions.  Non-coherent averaging can use disjoint
periods so long as you note the UT start/finish of each.

Yes, no need to waste time with inter-symbol gaps.  I think
with that you will establish some firm records.  A message
to Henny is a good prospect.

I found global average lightning data on the web, 2.5 deg
gridded data - perfect!

It is tempting to try to reproduce the diurnal noise pattern
from this.  Could be a neat way to test simple propagation
formula at long range.
