Overview

AI-generated overview

Remote MCP server for amateur radio: IARU Region 1 band plans, RF and antenna calculations, and Austrian callsign lookups.

What you can do
  • Look up band plans, list all bands and check whether a frequency is allowed
  • Calculate EIRP, cable loss, cable comparisons, SWR loss, wavelength and antenna lengths, battery runtime, and convert power units
  • Look up typical antenna gain values by antenna type
  • Search Austrian callsigns, check suffix availability by district, suggest and validate callsigns, and show database statistics
  • List the OERadio.at web tools with their descriptions
When to use it
Useful for licensed radio amateurs, especially in Austria and IARU Region 1, who want an assistant to answer band-plan questions, run station and antenna calculations, or check callsign availability and validity.
Requirements
A remote streamable HTTP endpoint; no account, API key or environment variable is declared. Clients that only support stdio need a bridge such as mcp-remote. Self-hosting requires Node.js 20 or later, optionally Docker.
Before you install
Callsign lookups query the official Austrian list and fall back to QRZ.com and HamQTH, so queried callsigns are sent to those third parties. Results are informational; verify band limits and RF safety figures against official sources before relying on them.

Installation

In SourceWeft

  1. Open Oeradio Mcp in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.achildrenmile%2Foeradio-mcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

OERadio MCP Server

[Featured on oeradio.at] [Live Demo] [License: MIT]

🎙️ Part of the oeradio.at open source ham radio tool collection. Browse all tools → oeradio.at/werkzeuge

Public MCP (Model Context Protocol) server providing amateur radio tools and calculations for IARU Region 1 operators.

Endpoint: https://oeradio-mcp.oeradio.at/mcp Author: OE8YML License: MIT

What is MCP?

Model Context Protocol (MCP) is an open standard that allows AI assistants to use external tools. Originally developed by Anthropic, MCP is now supported by Claude, ChatGPT, and Gemini. With this server, you can ask your AI assistant questions like "What are the band limits for 20m?" or "How long should my dipol be for 14.2 MHz?" and get instant calculations.

Austrian Callsign Tools

ToolDescription
callsign_lookupSearch Austrian callsigns (fb.gv.at, QRZ.com, HamQTH fallback)
callsign_availableCheck if a suffix is available across Austrian districts
callsign_suggestGenerate callsign suggestions based on name
callsign_validateValidate callsigns against Austrian rules
