[TowerTalk] get those HF EME antennas ready...

[Jim Lux]

Right above 40m band (7.405 MHz), and they DID run a bit more power than 
hams are allowed (3.4 MW), but they successfully bounced a signal from 
HAARP in Alaska to the moon and down to a receiving array in NM.

Good thing they were doing this when the sunspots are low, so the 
ionosphere lets it through...October 28, 9UT

Looks like the echo was about 25 dB below the ionosphere reflection.

Interesting pictures of their wideband HF antennas at the bottom.  More 
on the antenna at http://lwa.unm.edu/

The lowest takeoff angle for the LWA isn't that low(15 degrees), but it 
has a pretty good effective aperture (4 million square meters)
