MICOM-3F/3T/3R HF-SSB Owner’s Guide Using Automatic Link Establishment (ALE) The MICOM-3 unit supports the Automatic Link Establishment (ALE) function, a method that enables automatically selecting the best working channel from a group of preprogrammed channels without any user intervention, thereby facilitating communication among HF radio stations and improving the communications quality and reliability.
Using Automatic Link Establishment (ALE) Identification of a sounding signal sent from a station indicates a high probability of bidirectional communication. The length of the sounding cycles can be set to short or long cycles, depending on propagation conditions. When propagation changes are slow, long intervals of about 1 or 2 hours may be sufficient.
MICOM-3F/3T/3R HF-SSB Owner’s Guide • In a network of nine channels used by eight members, a 30-minute sounding cycle would result in 80% occupancy; a 60-minute cycle would result in 40% occupancy; a 90-minute cycle would result in 27% occupancy and a 120-minute cycle would result in 20% occupancy. • If there are only two or three channels in the network, a sounding cycle of 30 minutes allows enough channel-free time, even for as many as ten users.
Using Automatic Link Establishment (ALE) After a bidirectional handshake with a single station, the LQA matrices of both radios are updated. The operator can then initiate a call to that station and obtain the best channel automatically. When the bidirectional handshake procedure is performed with a net, all the stations in the net update their LQA tables.
MICOM-3F/3T/3R HF-SSB Owner’s Guide Individual Station Address The individual station address may contain 1, 2, 3, 4, or 5 words. To enable using addresses that are not an integer multiple of 3 characters (for example, an address consisting of 1, 2, 7, 8, 10, …, etc. characters), stuffing can be used: with stuffing, the last address word includes one or two stuffing symbols in the last position(s) (see the “stuff-1” and “stuff-2” patterns in Table 1).
Using Automatic Link Establishment (ALE) Group Addresses The purpose of a group call is to rapidly and efficiently establish contact with multiple nonprearranged (group) stations. To make a group call, a calling ALE station uses a sequence of the actual individual station addresses of the called stations. Special Addressing Modes – Use of Wildcards A “wildcard” is a special character,“?”, that a calling station can use to address multiple stations with a single call address.
MICOM-3F/3T/3R HF-SSB Owner’s Guide Table 2. Use of “?” Wildcard Symbol (Cont.) Pattern Interpretation @AB “Double selective AnyCall” address word, shown here for reference: only the last two characters in this word must be evaluated @A? “Double selective AnyCall” “wild-1” address word: only the middle character “A” in this word must be evaluated @?B Not permitted. Use “selective AnyCall” @?? Not permitted.
Using Automatic Link Establishment (ALE) the addresses of the desired subset of receiving stations (that is, it replaces the ? with an alphanumeric – see more details in Table 1). If even narrower acceptance and response criteria are required, double selective AnyCall may be used: this is identical to selective AnyCall, except that its special address (@AB) specifies the last two characters that the desired subset of receiving stations.
MICOM-3F/3T/3R HF-SSB Owner’s Guide During operation, the MICOM radio scans all the frequencies included in the defined nets: • When the radio receives a call, it responds with the self-address that is programmed in the radio for that net. • When initiating a call, you select the net you want to transmit to, and then select an address (a specific station, or any other type of address you wish to use).
Using Automatic Link Establishment (ALE) Using ALE Functions in the Channel Mode When the ALE mode is enabled, your radio can receive and transmit ALE calls even when you are using the Channel mode. For this purpose, the CALL (F1) key is displayed even in the Channel mode. The only restriction is that in the Channel mode, MICOM-3 uses only the ALE parameters of net 1. Therefore, if net 1 is not programmed, no ALE functionality is available in the Channel mode, even when the ALE mode is enabled.
MICOM-3F/3T/3R HF-SSB Owner’s Guide ALE Programming ALE supports many features, including: • Various type of calls • Up to 20 nets, each with its own set of members and associated frequencies (channels) • Up to 100 ALE addresses in the directory • Up to 100 scan channels • Up to 12 AMD (paging) messages. All the ALE features you can use on your radio can be programmed: to program or modify features, you can use the front panel of the radio, as described in the ALE Programming section.
Using Automatic Link Establishment (ALE) Receiving and Transmitting Calls in ALE Mode The MICOM-3 supports the following types of ALE calls: • Individual call – call directed to a specific station. • Net call – call directed to a net (a net is a preprogrammed group of stations). • Group call – call directed to a group of stations. • AllCall – call directed to all other stations simultaneously (broadcast call); can also be used as a distress call.
MICOM-3F/3T/3R HF-SSB Owner’s Guide ➤ Receiving a net call: MICOM-3 FROM NET CALL When your radio receives a net call (i.e., a call addressed to all the stations in your net), the display flashes a net call alert that alternates the words NET CALL with the calling station name. ➤ MICOM-3 FROM ABC Receiving an AllCall: Note You can program your radio to ignore incoming AllCalls.
Using Automatic Link Establishment (ALE) ➤ Receiving a sounding call: When the radio is in the ALE mode and it receives a sounding call from another station, the calling station name appears in the display, preceded by the letter S to identify that the call is a sounding call. MICOM-3 S ABCDE Within a few seconds, the radio automatically returns to the mode used before the call was received.
MICOM-3F/3T/3R HF-SSB Owner’s Guide Link State After the radio successfully receives or transmits a call, it is in the link state. MICOM-3 FROM ABC If the call was received from another radio, the display includes the word FROM in the first line, as well as the name of the station which initiated the call (if a message has been received, it is also displayed).
Using Automatic Link Establishment (ALE) Notes • If the name of the station you are linked to is not in your directory, this function will not be available. • The LQA (F3) key is displayed only if you established the link in the ALE mode (in the Channel mode, this function is not available, because the call is received/transmitted on the current channel). MICOM-3 MON (F4) turns on and off monitoring by means of the speaker.
