418SELCALL/ALE OPERATION■ Selcall or ALESelcall uses a 4 or 6-digit ID address and allows youto make individual or group calls. The ALE (automaticlink establishment) is a system which automatically se-lects the best frequency for the time of day, destinationand propagation, and establishes a communicationlink. The IC-F8101 ALE system compiles with basicrequirements of FED-STD-1045A.D Available calls• Selective callSelective call allows you to make individual or groupcalls using an individual ID (identification) assigned toeach transceiver.• Phone callAllows you to make a Phone call through a telephoneinterconnect service provider.• Message callAllows you to exchange text messages of up to 64characters* with the intended ID station.* Icom Selcall: 64 characters (upper case/Lower caseletters)Open Selcall: 32 characters (Only upper case let-ter)• Send Position callAllows you to send your own position information tothe intended ID station.• Get Position callThe Get Position call allows you to request the intend-ed ID station to send its position information.• Get Status callRequests an ID station to send radio status informa-tion including power supply voltage, signal strength,output power, VSWR, and so on.• Stun call (Only Open Selcall)The Stun call disables the specified station from eithertransmitting and receiving.• RFDS emergency call (Only Australian versions)The RFDS (Royal Flying Doctor Service) emergencycall uses a 2-Tone signal for an emergency call.• Emergency callAllows you to send an emergency signal along withyour own position information.• The Icom Selcall uses Icom’s original commands,and may not be compatible with other brands.• Depending on the presetting, you can select theOpen Selcall*.* The Open Selcall is compatible with other trans-ceiver brands. Ask your dealer for details.• Channel Test callThe Channel Test call allows the user to determine thesignal quality between their transceiver and a specifictransceiver, before making individual or group calls.• ALE individual or net callAutomatically establishes a communication link by us-ing the ALE table.• ALE AMD (Automatic Message Display)Automatically sends and receives text messages ofup to 90 characters. Unlink AMD call can also be se-lected.• ALE soundingAutomatically sends a sounding signal at a selectableinterval (0.5–11 hours) to check the propagation, andsaves the data in a table. Manual soundings can alsobe sent.• Update LQA (Link Quality Analysis)Automatically sends and receives the signal qualitybetween the transceiver and other stations.
