With the capability to call up a specific station, a group of stations, a net... or just CQ, ALE is a versatile system for connecting operators for voice, data, text, instant messaging, CW, or image QSOs. A radio operator can initiate an ALE call on HF or VHF. It is a direct radio calling system, that requires no infrastructure. It uses a digital signal on HF/VHF to connect. Each ham radio ALE station uses the operator's callsign as the calling signal. When not actively in a QSO with another station, each HF SSB transceiver constantly scans through a list of frequencies, listening for its callsign. To reach a specific station, the caller simply enters the callsign.
