an ale radio system enables connection for voice conversation, alerting, data exchange, texting, instant messaging, email, file transfer, image, geo-position tracking, or telemetry. with a radio operator initiating a call, the process normally takes a few minutes for the ale to pick an hf frequency that is optimum for both sides of the communication link. it signals the operators audibly and visually on both ends, so they can begin communicating with each other immediately. in this respect, the longstanding need in hf radio for repetitive calling on pre-determined time schedules or tedious monitoring static is eliminated. it is useful as a tool for finding optimum channels to communicate between stations in real-time. in modern hf communications, ale has largely replaced hf prediction charts, propagation beacons, chirp sounders, propagation prediction software, and traditional radio operator educated guesswork. ale is most commonly used for hooking up operators for voice contacts on ssb (single-sideband modulation), hf internet connectivity for email, sms phone texting or text messaging, real-time chat via hf text, geo position reporting, and file transfer. high frequency internet protocol or hfip may be used with ale for internet access via hf.
