29. Automatic Link Establishment (ALE)29

30. Operation ALE Fundamentals
Automatic Link Establishment (ALE) is a technique that permits HF radio stations to call and link on the best HF channel automatically without operator assistance.
ALE systems make use of recently measured radio channel characteristics stored in a memory matrix.
The system works much like a telephone in that each radio in a network is assigned an address (ID). When not in use, each radio receiver constantly scans through its assigned frequencies, listening for calls addressed to itself. 30

31. Operation ALE Fundamentals
SELF ADDRESS - identifies a radio. Each radio can have up to 20 self addresses. The AN/PRC-150 requires at least one 1 to 3 character self addresses to form the LQA matrix.
INDIVIDUAL ADDRESSES - identifies other individual stations in the network. ALE allows storage of up to 200 individual addresses.
NET ADDRESSES - identifies a group of individual stations which can be called together. ALE supports up to 20 net addresses. 31

32. Operation ALE Fundamentals
CHANNEL GROUP - listing of channels that were programmed in SSB mode which will be used as part of the ALE configuration. Maximum 50 Channel Groups; 100 channels per Group.
ASSOCIATED SELF - this is the particular self address that this unit will be known as to a specific individual address.
AUTO CALL - this type of call allows the radio to choose the best channel to place the ALE call on, based on the LQA scores for that address.
MANUAL CALL - this type of call allows the operator to choose the channel to place the ALE call on. 32

33. Operation Basic ALE Individual Call B A C D 33 1: 2: A, THIS IS B!
I HEAR YOU
B, THIS IS A!

?? ZZZZZZ
?? ZZZZZZ
Any station may contact another station by placing an INDIVIDUAL Call (point-to-point call)
The local station’s ALE controller selects the best frequency on which to call.
Individual call consists of a three-way message exchange.
Calling Station makes “Individual Call” page
Receiving Station “Response” - Response also includes signal quality information.
Calling Station “Acknowledges” - Acknowledgement includes signal quality information.
After the three-way message exchange or “handshake” the ALE function is completed and the stations are ready to pass traffic using any other available mode: CW, AM, SSB, Voice, Data….
Stations which are not involved in the call ignore the transaction C D
(C & D both hear the individual call, but realize it isn’t for them, so they do nothing.) 33

2.3: RESPONSE
Calling station selects the best frequency for contacting the maximum number of stations in the network.
The best frequency is chosen by reviewing LQA data for all Individual Addresses in the network.
If there isn’t a best frequency in the LQA data, the highest frequency channel is chosen.
Or, the frequency may be manually selected by the operator.
Individual Address stations reply in their designated time slot. The time slot is determined by the order of the station in the network member list (member #1 has time slot #1…..)
Calling station Acknowledges Network.

36. Operation Types of LQAs Exchange (Two-Way) LQA Sounding (One-Way) LQA
Most accurate LQA
Each station sends the other station LQA data
Both stations get LQA data
Both stations must transmit
Most time consuming
Sounding (One-Way) LQA
Not as accurate as Exchange LQA
Receiving station calculates LQA data for itself
Only receiving station gets LQA data
Only calling station transmits
Receiving stations can maintain radio silence
Faster LQA 36

37. Operation Types of LQAs Net Exchange LQA
Receiving stations send response messages in time slotted order.
May be very time-consuming for large nets.
Net call initiator measures signal quality during reception of messages. 37

4.2:
STATION A HEARS
ME WITH A SCORE OF “75” ON THIS CHANNEL. I’LL HAVE TO REMEMBER THAT!
STATION B HEARS
ME WITH A SCORE OF “80” ON THIS CHANNEL. I’LL HAVE TO REMEMBER THAT!
4.1:
During a Exchange or two-way LQA the two stations exchange LQA data.
LQA scoring is done at the receiving station and is passed on to the transmitting station.
Scores above 75 are generally suitable for voice or high speed data
Scores above 40 are generally suitable for data communications (based on data rate…lower rates support poorer channels)
Both stations store the LQA data and use this information for making calling channel decisions. 38

39. LQA Data Table for Station A
Operation
LQA Data Table
Station A
Each station has an LQA Data Table which contains all the Individual Addresses, Channels and corresponding LQA scores.
This table presently contains no LQA scores.
We’ll do an example to show how scores are saved.

B, THIS IS A!
1: SOUNDING CALL B A 2:
I HEAR STATION A SOUNDING LQA WITH ME. I CALCULATE AN LQA SCORE = 75 ON THIS CHANNEL. I’LL HAVE TO REMEMBER THAT!
During a Sounding or one-way LQA there is no exchange of data.
LQA scoring is done at the receiving station and is assumed to represent the LQA score of the reciprocal link.
Scores above 75 are generally suitable for voice or high speed data
Scores above 40 are generally suitable for data communications (based on data rate…lower rates support poorer channels)
Only the receiving station generates and stores the LQA data.
The receiving station maintains radio silence. 40
