General Dynamics upgrading Navy shipboard radio with longrange HF
This paper examines existing automatic link establishment (ALE) techniques for high frequency (HF) radio systems, identifying areas of improvement in calling techniques and protocols for ALE. Automated HF radio systems improved in these areas have been implemented, and results of these implementations are presented. Compromises between link establishment time and reliability are also considered.
ALEAutomatic Link Establishment(2G)
AUTOMATIC LINK ESTABLISHMENT Third-generation ALE (3G-ALE) is designed to quickly and efficiently establish one-to-one and one-to-many (both broadcast and multicast) links. It uses a specialized carrier-sense-multiple-access (CSMA) scheme to share calling channels, and monitors traffic channels prior to using them to avoid interference. Scanning
TX and RX condition assessment for proposed FH automatic link
Automatic Link Establishment (ALE) was developed to provide for establishing best quality high frequency communications without the need for consulting propagation forecast information, or the need of having training to interpret propagation forecast information.

AUTOMATIC LINK ESTABLISHMENT 3.1 Introduction and overview of automatic link establishment systems The United States has developed a series of HF radio standards that characterize and specify protocols and parameters for automatic link establishment (ALE), networking, linking protection, high-speed data modems, and basic HF radio parameters.
Automatic Link Establishment The Key to Reliable Helicopter NOE
One of the important developments in the HF communication is Automatic Link Establishment. ALE method is widely used by the military and other organizations. In this paper we have tried to describe the implementation of ALE military standard (188-141A). This standard defines a 2G HF ALE standard.

The focus of operation during this exercise is ALE (Automatic Link Establishment) and SELCALL (HF Selective Calling). Ham operators are invited to participate at any time during the 10 days of this free and open informal event.
PPT Automatic Link Establishment for Amateur Radio Status Report
Automatic Link Establishment (ALE) is a technology that takes the guesswork out of choosing the best frequency to use to contact a specific station. Stations on an ALE network periodically send out a signal that identifies the station. This is called sounding.
(PDF) Automatic link establishment for HF radios
ALE (Automatic Link Establishment) is based on government standards for automatically connecting HF radios. The protocol searches through available frequency bands and creates a channel that is appropriate for current band conditions.
Automatic Link Establishment
Automatic link establishment (ALE) is one of the important technologies in HF communication. One of the indicators to measure the performance of an ALE system is the linking time, which includes channel switching, spectrum sensing, and trying to call three periods. Asynchronous mode has been widely used for its simple operation. When establishing an link, the station sorts all the channels and.
