The characteristics obtained by using the absorption line of formaldehyde as a background for a transmitted signal are examined and compared with the Water Hole concept. It is shown that much greater distance may be accessed for a given transmitter power level and that the narrow band characteristics of the formaldehyde line are ideally suited to the transmission of low frequency coded 'calling' signals. It is further shown that two unique harmonic overtones lie above and below the 4830 MHz formaldehyde line, and by using these further aids, a clear and unambiguous interstellar communication system could be established without the background maser noise that would be expected from the use of the Water Hole. It is concluded that the Formaldehyde Window is a viable alternative to the Water Hole concept, with an advantage of being an easily distinguished artifact of intelligence.
