International Amateur Radio ALE Standards In addition to the global standard ALE protocols, the following documents hereby provide the public documented technical characteristics called for in FCC rules � 97.309(a)(4) :

"(4) An amateur station transmitting a RTTY or data emission using a digital code specified in this paragraph may use any technique whose technical characteristics have been documented publicly, such as CLOVER, G-TOR, or PacTOR, for the purpose of facilitating communications." "Documentation should be adequate to (a) recognize the technique or protocol when observed on the air, (b) determine call signs of stations in communication and read the content of the transmissions."
