Purpose and description
Enable an AI agent to recognise amateur-radio activity, assess an operator and station's readiness, and identify appropriate next actions given technical conditions, operating purpose and applicable authorisation.
Amateur radio is the practice of radio communication, technical investigation and self-training by duly authorized people interested in radio technique for personal purposes and without pecuniary interest.
It can be Classify a proposed radio activity and identify unresolved service-boundary questions.; Compare a proposed transmission with documented operator, station and location-specific permissions.; Prepare a station-readiness assessment for a stated band, mode, antenna and power setting.; Select candidate operating windows and propagation paths while expressing uncertainty about contact success.; Guide contact, net or experimental procedures and record the resulting evidence.; Diagnose unsuccessful contacts or interference reports and propose bounded corrective checks..
Distinguishing features
Classify the activity by its purpose and service context, rather than assuming that any use of a transceiver is amateur radio.
Determine whether the operator is communicating, training or experimenting within an amateur-radio framework; equipment capable of receiving amateur bands is insufficient evidence.
Distinguish amateur-radio contacts from broadcasting intended for a general audience, while recording any locally permitted special transmission activities separately.
Distinguish amateur-radio public-service participation from professional emergency communications by recording the operator's role, authority and relationship to the responsible organisation.
Treat amateur-satellite operation as a related operating context whose applicable service rules must be checked, rather than assuming every terrestrial permission transfers unchanged.
Scope
+ Activity purpose and its fit with amateur-radio practice
+ Operator and station authorisation in the relevant jurisdiction
+ Station configuration, transmission readiness and interference management
+ Band, mode and propagation choices for intended contacts
+ Contact procedures, experimentation, logging and community participation
- Radio equipment design and manufacturing as independent products
- Commercial broadcasting and professional telecommunications service delivery
- Citizens band, personal radio and other separately governed radio services
- Spectrum administration as an institutional process
- Emergency management and incident command beyond the amateur-radio contribution
Characteristics
- Operating purpose
- social contact | self-training | technical investigation | contesting | public-service support | other documented purpose Purpose helps establish the activity boundary and the procedures and evidence needed to evaluate it.
- Applicable operating jurisdiction
- Operating location and date linked to the responsible authority and applicable rules Permissions cannot be inferred from a callsign, nationality or equipment capability alone.
- Operator authorisation
- verified for proposed operation | partially verified | expired | absent | unknown The agent must distinguish evidence of qualification from permission for a particular transmission.
- Station and operator identification
- Operator, station identifier or callsign, responsible person and any supervision arrangement Shared and remotely controlled stations can separate the person operating from the station's accountable identity.
- Operating frequency
- Hz, with occupied frequency range where known The full transmitted signal must be considered when assessing band fit and coexistence.
- Emission mode and occupied bandwidth
- Mode or emission designation, with occupied bandwidth in Hz Voice, Morse, image and data operation create different compatibility and operating requirements.
- Transmit power
- W, specifying measurement point and whether mean, peak-envelope or another defined power measure Unqualified power figures are insufficient for comparing station settings with technical or regulatory constraints.
- Propagation path
- direct terrestrial | ionospheric | repeater-assisted | satellite | Earth-Moon-Earth | other documented path Path choice affects timing, antenna requirements and the feasibility of the intended contact.
- Station readiness
- receive-only ready | transmit-ready for stated configuration | restricted | faulted | unassessed Readiness is specific to a configuration and operating context, rather than a permanent property of a station.
- Contact outcome
- attempted | one-way reception | partial exchange | completed exchange | independently confirmed | disputed Hearing a signal, exchanging information and obtaining confirmation are different outcomes.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 6 bundles · 11 layers · 19 findings · 29 questions.
Purpose and service boundary Establishes what the activity is trying to achieve and why it belongs within amateur radio.
Radio hardware and frequencies alone do not identify the practice or settle whether a proposed use fits it.
Activity purpose
Records the operator's intended communication, learning or investigative outcome.
Purpose evidence
Capture the actual intended exchange or experiment, including beneficiaries and any organisational or financial context.
- What makes this activity amateur-radio communication, self-training or technical investigation? definition
- Does the proposed traffic introduce a professional, commercial or general-audience purpose requiring a separate boundary assessment? boundary
Participation context
Distinguishes transmitting, listening, supervised participation and infrastructure support.
Participant role
Record what each participant actually does without equating listening or club membership with transmitting authority.
- Is the participant listening, transmitting, supervising, experimenting or maintaining shared infrastructure? definition
- Which proposed actions require evidence beyond participation in the amateur-radio community? action
Authorisation and accountability Connects proposed operation to documented permissions and responsible people.
An amateur station may operate under different conditions when moved, shared, remotely controlled or used under supervision.
Operating permissions
Records the jurisdiction, current evidence and scope of authority for the specific operation.
Permission envelope
Assess permission against location, date, operator status, frequency, emission and power rather than a single licensed flag.
- Which authoritative records establish permission for this operator and station at the proposed location and date? provenance
- Which parts of the proposed frequency, mode, power and control arrangement are verified, restricted or unresolved? boundary
Station control
Records identification, supervision and responsibility for starting and stopping transmissions.
Responsible control
Make the relationship between operator, station identity and controlling person explicit, especially for club and remote stations.
- Who is accountable for transmissions, and what evidence connects that person to the station identification being used? provenance
- How can the responsible person supervise operation and stop transmission if control or supervision fails? action
Station and spectrum readiness Assesses whether the configured station can carry out the intended operation with understood technical limits.
Amateur-radio operation depends on the complete transmitter, feed line, antenna and site configuration, including its effects on other spectrum users.
Radio-frequency chain
Connects equipment settings to antenna-system behaviour and usable station performance.
Configured station
Record the actual signal path, band compatibility, power settings and measurements supporting readiness.
- Which transceiver, amplifier, filters, feed line and antenna form the active signal path? definition
- What measurements establish power delivery, antenna match and relevant losses for this configuration? measurement
Emissions and site conditions
Assesses unwanted emissions, interference evidence and site-specific operating constraints.
Transmission readiness evidence
Separate observed problems from suspected causes and record the checks needed before or during transmission.
- What observations or measurements assess occupied bandwidth, unwanted emissions and reported interference? measurement
- What checks or restrictions follow from unresolved RF exposure, electrical, antenna-support or interference concerns at this site? action
Propagation and contact execution Links the intended correspondent and exchange to a feasible path and operating procedure.
A correctly configured station can still fail to make contact because propagation, timing, mode or access procedures do not align.
Path feasibility
Records the proposed path and the evidence supporting a band, antenna direction and operating window.
Contact opportunity
Represent contact feasibility as an evidence-based estimate whose assumptions may change during operation.
- What path is intended, and which observations, forecasts or infrastructure availability support the chosen band and time? provenance
- What received-signal, noise or failed-attempt evidence would justify changing the band, mode, direction or operating window? action
Exchange procedure
Defines how the operator enters an exchange, identifies participants and recognises its completion.
Contact protocol
Record procedures appropriate to a direct contact, repeater, digital exchange or controlled net.
- What calling, identification, access and turn-taking procedures apply to this operating context? action
- What information must be successfully exchanged before this contact counts as complete? definition
Learning, records and coordination Preserves evidence from contacts and experiments and defines participation in organised amateur-radio activity.
Amateur radio includes cumulative technical learning and coordinated operation whose success cannot be judged solely by whether a signal was transmitted.
Operating and experimental records
Distinguishes contact logs, confirmations, operator reports and measured experimental results.
Evidence quality
Keep enough context to interpret contact claims and assess whether an equipment or procedure change improved performance.
- Which time, frequency, mode, station identities and exchange details support the recorded contact outcome? provenance
- For an experimental comparison, what measurements and controls distinguish the tested change from propagation or noise variation? measurement
Organised operation
Records roles and objectives in clubs, contests, nets and public-service exercises or activations.
Participation commitments
Separate event procedures and community expectations from regulatory authority and external incident-management responsibilities.
- Which organiser defines the exchange, assigned role, reporting route and success criteria for this activity? provenance
- When must the operator defer, stop or hand traffic to another participant or responsible organisation? action
