We are a small company of enthusiasts inspired by Space. We have developed a solution for sending online messages into Space using a relatively simple radio equipment. For transmission, Message in Space uses 446 MHz UHF radio frequency (wavelength of about 67.2 cm), which does not require licensing in most countries of Europe. The maximum allowed effective radiated power for this frequency is 0.5 W. The radio signal is transmitted directionally, using 6 element Yagi-Uda antenna with boom length of 1130 mm.
▌ PHILOSOPHY
The Message in Space project explores the topic of METI (Messaging Extraterrestrial Intelligence⤴ ) . While we could create a website with a purely theoretical discussion of this topic, we decided that a practical implementation of radio messaging into Space would be more interesting. For a start, we selected a simple radio transmission setup, which meets basic requirements for sending a radio signal into Space and can be operated without licensing. We propose to call it "Amateur METI" or AMETI .
