Arecibo Uncut: First Visit to the Platform & Dome with Dana Whitlow
@spenchdotnet | During my time at the Arecibo Radio Observatory being part of the Away Team for the ISEE-3 Reboot Project:

In August 2001 two new crop formations were reported near Chilbolton radio telescope in Hampshire, UK. Both were very impressive looking and consisted of a large number of small 'pixels', which when viewed from the air formed a recognisable shape - unlike many other crop formations. One represented a "human face" and the other resembled AN ANSWER to the Arecibo message. A radio transmission that SETI (the Search for Extra-Terrestrial Intelligence), sent from the Arecibo radio telescope in 1974 Then one year later, in August 2002, another impressive formation was discovered just to the west of Winchester (only about 8½ miles to the southeast of the Chilbolton formations). An "alien face" with a circular grid containing a coded message. When the code is broken, it reads: "Beware the bearers of false gifts & their broken promises. Much pain but still time. There is good out there. We oppose deception. Conduit closing." Are these circles genuine? We cant know for sure, since no one investigated them to see if there were significant crop/soil anomalies. But they do seem very sophisticated.

The Arecibo Message is Answered
The Arecibo message was beamed into space a single time (not repeated) via frequency modulated radio waves at a ceremony to mark the remodeling of the Arecibo radio telescope on 16 November 1974.[1] It was aimed at the globular star cluster M13 some 25,000 light years away because M13 was a large and close collection of stars that was available in the sky at the time and place of the ceremony.[2] The message consisted of 1679 binary digits, approximately 210 bytes, transmitted at a frequency of 2380 MHz and modulated by shifting the frequency by 10 Hz, with a power of 1000 kW. The "ones" and "zeroes" were transmitted by frequency shifting at the rate of 10 bits per second. The total broadcast was less than three minutes. (
