Italy LRC Marine Radio common mistakes
Italy LRC Marine Radio · Understand the traps and how to avoid them.
When asked which equipment a vessel must carry, the candidate answers from the vessel's size or type alone, without first stating the sea area (A1/A2/A3/A4) in which it will operate, and so selects the wrong GMDSS package.
Carriage requirements in the GMDSS are built as a two-step logic: sea area first, then equipment. Candidates memorise equipment lists as if they were fixed for a category of ship, and under time pressure they skip the sea-area step. The Italian exam often describes a vessel by its navigation limits rather than naming the area explicitly, so the candidate must derive A1–A4 from the described distance from a coast station or shore.
What to do instead
Practise a fixed two-line routine before answering any carriage question: (1) write the sea area implied by the scenario, quoting the definition (A1 within VHF DSC coverage of at least one coast station, A2 beyond A1 but within MF DSC coverage, A3 beyond A2 within an Inmarsat/recognised satellite coverage, A4 outside A1–A3); (2) only then list the mandatory items for that area. Do ten scenarios where the area is described indirectly (e.g. 'operates up to 150 nautical miles offshore in the Mediterranean') and check your derived area against the definitions.
The candidate treats a DSC distress alert as the whole distress call and thinks voice procedures on channel 16 are optional or can be skipped once the alert is sent.
DSC and radiotelephony are taught as separate chapters, so candidates learn the alert format and the MAYDAY format in isolation and never internalise the combined sequence. They also confuse the automatic acknowledgement from a coast station with the completion of the distress procedure.
What to do instead
Learn the sequence as one script: distress alert on DSC (or Inmarsat) → wait briefly for DSC acknowledgement → transmit the MAYDAY distress call and message by radiotelephony on the distress traffic channel (VHF channel 16, then usually move to a working channel as directed) → maintain watch and follow the coast station's control of the distress traffic. Rehearse it aloud as a single continuous flow, including the case where no DSC acknowledgement arrives and the alert must be repeated or escalated.
On VHF the candidate cannot keep the channel functions straight: using channel 16 for routine working traffic, transmitting on channel 70 by voice, or forgetting that channel 13 is the bridge-to-bridge channel and channel 06 is the inter-ship channel.
Channel numbers are memorised as a list without the underlying logic (16 = distress/safety/calling, 70 = DSC only, 13 = bridge-to-bridge, 06 = inter-ship, plus the marina and port operation channels), and the candidate has rarely operated a real set where the channel selector and the DSC controller are separate.
What to do instead
Build a small channel table with three columns: channel number, purpose, and 'voice allowed yes/no'. Drill the forbidden cases explicitly (no voice on 70, no routine chat on 16, no long calls on 16 before moving to a working channel). Then practise on a simulator or training set: place a routine call, move to a working channel, and send a DSC test call, so the physical separation of DSC and voice becomes familiar.
When describing MF/HF distress procedures, the candidate gives a VHF-style answer: one frequency, immediate voice, and no mention of the DSC alert on 2187.5 kHz, the radiotelephony distress frequency 2182 kHz, or the NBDP/DSC follow-on.
Most candidates train primarily on VHF and transfer that mental model to MF/HF. The MF/HF band adds a layer (dedicated DSC frequencies, the 2182 kHz voice frequency, NBDP for telex distress traffic, and the need to select the right band for the distance and time of day) that is easily lost if it is only read, not practised.
What to do instead
Write out the MF/HF distress chain once by hand: DSC alert on 2187.5 kHz (MF) or the appropriate HF DSC frequency → voice distress traffic on 2182 kHz (MF) or the paired HF radiotelephony frequency → NBDP where telex is used. Then answer five scenario questions where you must choose MF versus HF versus VHF based on distance, and justify the choice. Include the propagation reason (ground wave versus skywave) in each answer.
The candidate confuses the roles of NAVTEX, SafetyNET/SafetyCAST and EGC: stating that NAVTEX carries all GMDSS safety information worldwide, or that SafetyNET is received on the NAVTEX receiver.
All three deliver maritime safety information, so the names blur together. Candidates remember 'safety information comes by radio' without the delivery path: NAVTEX is a terrestrial MF service on 518 kHz (international) with limited range, while SafetyNET/SafetyCAST are satellite-based EGC services with near-global coverage, and SafetyCAST is the Iridium-based system.
What to do instead
Make a three-row comparison table (service, bearer/frequency, coverage, typical message types, receiver). Then answer questions by first asking 'terrestrial or satellite?' and 'what is the coverage area?'. Add the practical detail that NAVTEX uses specific message categories and that the receiver should be configured for the correct transmitter groups and message types rather than left on 'all'.
The candidate treats the EPIRB and the SART as interchangeable emergency devices, or cannot say what each one does after activation: which frequency, which satellite system, and what a rescuer actually sees.
Both are 'emergency beacons' in the candidate's mind, and both are covered in one chapter. The distinction (EPIRB transmits to the COSPAS-SARSAT system on 406 MHz with a 121.5 MHz homing signal and identifies the vessel; SART is a radar transponder on 9 GHz that paints a series of dots on a nearby radar screen) is understood in principle but not fixed in memory.
What to do instead
Learn one sentence per device: 'EPIRB = 406 MHz to the satellite system, identifies the ship, 121.5 MHz for homing'; 'SART = 9 GHz radar transponder, shows as a line of dots on a rescuer's radar, range roughly a few nautical miles, mounted high and switched on only when abandoning ship'. Then practise the operational questions: where it is stowed, how it is activated, how it is tested, and what the battery and registration requirements are.
The candidate answers licensing and identification questions loosely: giving the ship's name instead of the call sign or MMSI, confusing the ship station licence with the operator's certificate, or misstating who is responsible for the radio installation.
Regulatory topics feel like administrative background rather than examinable content, so they are skimmed. The identifiers (call sign, MMSI, DSC group and coast station identities) are also easy to mix up because they all appear in the same DSC menus.
What to do instead
Separate the three identities explicitly: call sign (letters/numbers assigned to the station), MMSI (nine digits, with the leading digits identifying ship, group or coast station), and the operator certificate (personal qualification). Then learn the responsibility chain: the licensee is responsible for the station, and the person holding the certificate operates it. Test yourself by writing the correct identifier for a given scenario rather than recognising one from a list.
The candidate explains propagation only in slogans ('HF goes further at night') and cannot link frequency choice to distance, time of day, or the antenna in use.
Propagation is abstract and candidates memorise a few phrases without a model. They also do not connect the antenna (its length, height, and grounding) to the practical result, so they cannot explain why a particular band works or fails on a given vessel.
What to do instead
Build a simple mental model: VHF is essentially line-of-sight, so range depends on antenna height; MF uses ground wave by day and is limited at night; HF uses skywave via the ionosphere, with lower frequencies better at night and longer distances, higher frequencies better by day. Then practise choosing a band for three scenarios (short-range VHF, medium-range MF, long-range HF at night) and state the antenna and grounding implications for each.
The candidate ignores EMC and interference in operational answers: not recognising that a nearby transmitter, a poorly routed cable, or a shared power supply can cause interference, and not knowing the first steps to take.
EMC is treated as an engineering topic outside the operator's role, so candidates answer 'call the technician' without the diagnostic steps. In practice the exam expects the operator to recognise interference, isolate its likely source, and apply basic remedies before escalating.
What to do instead
Learn a short interference routine: identify the symptom (breakthrough, noise, desensitisation), check whether it correlates with another transmitter or a device on board, check antenna and cable routing and grounding, check the power supply and bonding, and only then escalate. Practise with three scenarios (interference to the VHF from a nearby transmitter, noise from a faulty power supply, interference to a navigation receiver) and write the first three actions for each.
The candidate mishandles the power supply and basic maintenance questions: assuming the radio can run from the main battery without regard to the dedicated reserve source, or not knowing what to check when the set will not transmit.
Power and maintenance are seen as background, so the reserve power source requirement and simple fault-finding steps are not learned. Candidates also confuse a battery's state of charge with its capacity and do not know the routine checks (fuses, antenna continuity, connections, battery voltage).
What to do instead
Learn the reserve power requirement as a fact with its purpose (the radio must keep working when the main supply fails), and learn a five-step 'will not transmit' checklist: power supply and fuses, antenna connection and continuity, correct channel and mode selected, DSC controller status, and battery voltage under load. Rehearse the checklist on a training set so the order becomes automatic.
