How do ALE stations establish contact?
- A.ALE constantly scans a list of frequencies, activating the radio when the designated call sign is received (correct answer)
- B.ALE radios monitor an internet site for the frequency they are being paged on
- C.ALE radios send a constant tone code to establish a frequency for future use
- D.ALE radios activate when they hear their signal echoed by back scatter
WhyALE stations establish contact by constantly scanning a list of frequencies and activating when a call addressed to their own designated call sign is received. Automatic Link Establishment (ALE) stations constantly scan a preprogrammed list of frequencies, and the radio activates and locks onto a channel when it detects a call addressed to its own designated call sign, letting the station be reached without an operator manually tuning around, answer A. It doesn't rely on an internet paging site, a constant tone-code broadcast, or listening for a backscattered echo of its own signal, those don't describe how ALE actually works.
