From the ARRL Newsletter of April 24:
*Technology: HAARP-Like Ionospheric Research Project Underway at Arecibo Observatory*
"Work is underway to complete the construction of an ionospheric research facility at the?Arecibo Observatory?in Puerto Rico that bears some similarities to the High Frequency Active Auroral Research Program (HAARP) far to the north in Alaska, but on a different scale and with different research goals."
Six arrays will use 5.1 and 8.175 MHz to warm the ionosphere.
