INFORMATION NOTES ABOUT
AMATEUR RADIO ALE CHANNELS
Note 1
 
All Amateur Radio ALE channels use "USB" Upper SideBand (including frequencies below 9MHz). USB conforms to International Standards for Automatic Link Establishment, and enables interoperability. 
Note 2
 
This ALE channel list is in everyday use in the Amateur Radio service, for normal communication internationally, regionally, and locally. ALE channels are frequency coordinated internationally, and operators may be subject to the different rules, regulations, and bandplans of their region and local country of operation.

There is commonly an amateur radio ALE signal active on the air, every minute of every day on the primary ALE frequencies, somewhere in the world. It is the responsibility of every ALE operator to maintain the highest standards for all transmissions. Some channels or modes in the list may not be available in every country. The HF spectrum is a shared resource, so there is no guarantee that a channel is clear in a local area or region. ALE uses active LBT (Listen Before Transmit) technology. If a channel is occupied at any given moment, ALE waits or selects another channel instead.
Note 3
 
Amateur Radio ALE standards:
1. 2G-ALE System= MIL-STD 188-141 ; FED-1045 (8FSK - 2kHz Bandwidth)
2. If repetitive sounding, transmit soundings only on the Primary Data Channels for your IARU Region, otherwise use Manual/Attended sounding.
3. Duration of calling or sounding transmission: Optimum 16 seconds; Maximum = 22 seconds.
4. Sounding Interval= 60 Minutes (or more) for same channel.
5. Use of "This Was Sound" (TWS) is preferred.
6. Scan rate: 1 channel per second when scanning 10 channels or less.
7. Scan rate: 2 channels per second when scanning 11 channels or more.
8. Digital Modes Centre Audio Frequency = 1625Hz
9. Short text messaging standard = AMD .
10. Always transmit "CLEAR LINK" after ALL CALLS, QSOs, and LINKS!
11. Nets have 3 total member slots, with self address in SLOT #1.
Note 4 Amateur ALE Net Calls (Net Address)
1. HFN = Open calling of any Data/Text ALE Station
2. HFL = Open calling of any Voice SSB ALE Station
Note 5*
 
The 5MHz channels and band frequency segments vary in each country. 
USA: Operators on the 5MHz channels may use NALE (Non-Automatic Link Establishment) with Manual/Attended sounding or no sounding.
Note 6
 
HFLINK is an international resource: for radio operators using ALE Automatic Link Establishment and Selcall Selective Calling; for the  development of communications for organisations, Emergency / Disaster Humanitarian Relief networks; and for the development of ALE operating methods applicable to Amateur Radio Service. HFLINK is the Frequency and Address Coordination group for International Amateur Radio ALE and Selective Calling. 
Note 7

Date
 
Effective on 08 JANUARY 2018, this list supersedes all previous channel lists.
