the arecibo message was broadcast into space a single time via frequency modulated radio waves at a ceremony to mark the remodeling of the arecibo radio telescope in puerto rico on 16 november 1974.
arecibo mesajı, frekans modülasyonlu radyo dalgaları yoluyla, arecibo radyo teleskobunun yenilenmesini kutlamak için yapılan 16 kasım 1974 tarihindeki törende, yalnızca bir kez (tekrarlı değil) uzaya gönderilmiştir.

full transponder mode (e.g., 72 mhz)* luma signal is frequency-modulated (fm), but with a 50 hz dithering signal to spread out energy over the transponder* chroma is phase-modulated (pm)* an fm subcarrier of 4.50, 5.50, 6.0, 6.50 or 6.65 mhz is added for mono sound* other fm subcarriers (usually 7.02, 7.20, 7.38, 7.56, 7.74 and 7.92 mhz) are added for a true-stereo service and can also carry multi-lingual sound and radio services.
