Yup. That's just what the government wants you to think.
Just kidding a little. I believe that HARP did work but not to
do anything nasty. The idea was to "heat" the ionosphere by
transmitting a carrier in to it at a frequency that had been
calculated to be at the ionosphere's maximum absorption
frequency. This would cause it to ionize and create a man-made
Sporadic E-type opening that the Defence Department could use to
communicate on VHF and maybe even UHF .

	I think I read in QST where some hams took part in the
experiment and were able to communicate as high as 220 MHZ via
SSB with weak fluttery signals that reminded folks of aurora
propagation.

	When the HARP transmitter in Alaska was switched off,
the propagation went away some time later as the ionized cloud
disbursed.

	There have also been experiments to create propagation
by launching a shell full of copper needles which would explode
at some hight and create a temporary reflective layer for radio
signals. I think that also worked but not well. You'd need too
many needles to do much good.
