About

Beacon is a hand-curated amateur (ham) radio reference. license_class_info covers Technician, General and Amateur Extra privileges — HF/VHF/UHF access, power limits, exam requirements — or lists all three. frequency_band_info gives real allocation data for all 15 amateur bands (160m through 23cm): frequency range, which license class(es) may use it, and notes. phonetic_alphabet_lookup gives the NATO/ICAO phonetic alphabet. q_code_lookup gives the meaning of Q-codes like QRZ, QTH and QSL. db_watts_converter converts between decibels and watts in either direction against a chosen reference power. propagation_basics_guide explains HF skywave/skip, VHF line-of-sight/sporadic-E and UHF line-of-sight/tropo ducting. emergency_comms_info covers ARES vs RACES and ham radio's disaster-communication role. repeater_basics_guide explains offsets and PL/CTCSS tones. radio_glossary defines common terms (73, QSO, DX, simplex, ...). Keyless; fully local; verified as of its stated build date.

Sources: Hand-curated from ARRL and FCC Part 47 CFR 97 sources as of build date; fully local, zero upstream calls

What Beacon is for

The question that comes up whenever someone is studying for a ham radio license, prepping for a Field Day, or just curious what a friend's callsign chatter means — what can a Technician actually operate, what's on 20 meters, what does QRZ mean, how do repeater offsets work — answered from one hand-curated, verified reference instead of a scavenger hunt across forum posts and outdated PDFs.

What it does

Privileges for each of the three US amateur license classes — Technician, General, and Amateur Extra — including HF/VHF/UHF frequency access, power limits, exam question counts and prerequisites (license_class_info); real frequency-band allocations for all 15 amateur bands from 160 meters through 23 centimeters, with which license class(es) may use each and on what segments (frequency_band_info); the complete NATO/ICAO phonetic alphabet (phonetic_alphabet_lookup); common Q-codes like QRZ, QTH, QSL and QRM (q_code_lookup); an exact dB-to-watts and watts-to-dB calculator (db_watts_converter); plain-language propagation basics covering HF ionospheric skip, VHF line-of-sight and sporadic-E, and UHF line-of-sight and tropospheric ducting (propagation_basics_guide); ham radio's role in disaster response, including how ARES and RACES differ (emergency_comms_info); how repeater offsets and PL/CTCSS tones work (repeater_basics_guide); and a glossary of common terms and abbreviations like 73, QSO, DX and simplex (radio_glossary).

What it is not

Not a license-exam question bank, a live regulatory feed, or a substitute for the FCC's actual rules. Beacon is a hand-curated reference, cross-checked against ARRL and FCC Part 97 sources as of the build date stated in its own data (every tool response carries that date). Frequency allocations and license privileges do change from time to time — for anything license-exam-critical or operationally critical, always confirm against arrl.org or the current FCC Part 97 text rather than relying on this alone.

Tools

Licensing

license_class_info — One US amateur license class's privileges — HF/VHF/UHF frequency access, power limits, exam question count and prerequisite — or all three classes if omitted. Use for "what can a Technician do", "what's the difference between General and Extra", "how many questions is the Extra exam". Args: class_name.

Bands & Codes

frequency_band_info — A real amateur frequency band's range, which license class(es) may use it and on what segments, and notes on typical behavior. Use for "what frequencies are on 20 meters", "can a Technician use 6 meters", "what's 70 centimeters used for". Args: band.

phonetic_alphabet_lookup — The NATO/ICAO phonetic alphabet — used worldwide by amateur, aviation, maritime and public-safety radio to spell callsigns clearly — one letter or the complete A-to-Z list. Use for "what's the phonetic for the letter K", "give me the full phonetic alphabet". Args: letter.

q_code_lookup — The meaning of a ham-radio Q-code (QRZ, QTH, QSL, QRM, QSY, QRP, QSO, ...), one code or the full list. Use for "what does QRZ mean", "what's QTH", "list common Q-codes". Args: code.

Calculator

db_watts_converter — Converts between decibels and watts: dB = 10*log10(power / reference), power = reference * 10^(dB/10). Use for "convert 100 watts to dB", "how many watts is +20 dBm", "what's 3 dB in power terms". Args: value, direction, reference_watts.

Operating

propagation_basics_guide — How radio waves travel on HF (ionospheric skywave/skip), VHF (line-of-sight plus sporadic-E), and UHF (line-of-sight plus tropospheric ducting) — general factual physics, not a live space-weather forecast. Use for "how does HF skip work", "why does 6 meters open up sometimes", "what's the ionosphere". Args: band_type.

repeater_basics_guide — How FM repeaters work: input/output frequency offsets, PL/CTCSS sub-audible tones, and simplex versus repeater operation. Use for "how does a repeater offset work", "what's a PL tone", "simplex vs repeater".

emergency_comms_info — Ham radio's role in disaster and emergency communication, and how ARES (the ARRL's volunteer Amateur Radio Emergency Service) differs from RACES (the government-activated Radio Amateur Civil Emergency Service). Use for "what's ARES", "what's the difference between ARES and RACES", "why do hams help in disasters".

Reference

radio_glossary — Definitions of common ham-radio terms and abbreviations (73, QSO, DX, CQ, repeater, simplex, duplex, net, elmer, rig, HT, rag chew, roger, Field Day). Use for "what does 73 mean", "what's a rag chew", "what's an elmer in ham radio". Args: term.

Conventions

  • Read-only. Every tool reads public data or computes; nothing is written anywhere and nothing about the user is stored.
  • Result envelope. ok: true with data, or ok: false with a structured error (bad_input, not_found, upstream_error). degraded lists optional sources that were unreachable.
  • Rate limits. Free tier 60 tool calls/minute and 300/day per user (keyed on the user identifier supplied by the host agent, else client IP); Pro keys raise this. Over-limit calls return HTTP 429 with Retry-After. initialize and tools/list are never counted.

Beacon — Privacy Policy

Effective 24 September 2026. Unify Dynamics LLC ("we", "us"), Menlo Park, California.

What Beacon is. Beacon is a connector (an MCP server and REST API) that AI assistants and personal agents call on your behalf for an amateur (ham) radio reference: license class privileges, frequency band allocations, Q-codes, the phonetic alphabet, a dB/watts calculator, propagation basics, repeater fundamentals, and emergency-communication background. You interact with your assistant; the assistant sends us only the arguments needed for that one lookup or calculation.

What we receive. The arguments of each tool call — a license class name, a band name, a letter, a Q-code, a term, or the numbers for a dB/watts conversion — the technical headers needed to serve the request (an IP address or a client identifier supplied by the assistant, and a Pro API key if you have one), and standard server logs.

Everything is answered from a bundled, hand-curated reference file and nothing is stored. No request is forwarded to any third party — there is no upstream call at all, live or otherwise — and no query is logged in request bodies, recorded, or used to train anything.

What we do not receive or store. We do not receive your conversation with the assistant or your name, and we do not build a profile from your queries: each request is answered independently and nothing carries over between requests. Rate-limit counters (a client identifier and timestamps) are held in memory for at most 24 hours. Hosting-provider access logs, which contain IP addresses and request paths but not request bodies, are retained for up to 30 days for security and abuse prevention.

Sub-processors. None — the entire dataset is bundled with the server and answered locally. Hosting: Vercel (United States regions).

Legal bases and your rights. Our processing is necessary to provide the service you request through your assistant. Because we store no personal data beyond short-lived logs, requests to access, correct or delete personal data are usually satisfied automatically; you can still contact agent@connectorbay.com and we will respond within 30 days. We do not sell or share personal information and do not use your data to train models.

Children. Beacon is a general-audience service operated by the adult using the assistant.

Changes. We will post changes here with a new effective date.

Terms of service

Beacon — Terms of Service

Effective 24 September 2026. These terms govern use of the Beacon connector ("the Service") operated by Unify Dynamics LLC ("we", "us").

  1. The Service. Beacon returns a hand-curated amateur (ham) radio reference — license class privileges, frequency band allocations, Q-codes, the phonetic alphabet, a dB/watts calculator, propagation basics, repeater fundamentals, and emergency-communication background — from data cross-checked against ARRL and FCC Part 97 sources at build time. It is accessed through an AI assistant or directly over MCP or HTTP.
  2. Not a substitute for the FCC's rules, and not an exam prep product. Beacon is an independent reference tool, not affiliated with or endorsed by the FCC, the ARRL, or any examining body. It is not a license-exam question bank and should not be relied on as your sole source when studying for an exam or making an operating decision with regulatory consequences.
  3. Facts change. License privileges and band allocations reflect ARRL/FCC sources as of the build date stated in the Service's own data; always check the current FCC Part 97 text or arrl.org for anything license- or operationally critical.
  4. Acceptable use. Automated use within the published rate limits is welcome.
  5. Availability. The Service is provided "as is" without warranty. We may change, limit or discontinue it at any time.
  6. Data. Our Privacy Policy describes what we process. In short: your query is answered from a bundled reference file, and nothing is stored.
  7. Pro keys. Optional Pro API keys are issued at our discretion, are personal to the holder and may be revoked for abuse.
  8. Liability. To the fullest extent permitted by law, Unify Dynamics LLC is not liable for any loss arising from use of or reliance on the Service. Our total liability is limited to US $100.
