LoTW FAQs

Question 1

Which AI assistants are compatible with LoTW?

Accepted Answer

LoTW seamlessly integrates with a range of popular MCP-compatible AI clients, including Claude, ChatGPT, Cursor, and Gemini, allowing you to ask natural language questions about your LoTW data.

Question 2

What is LoTW (this tool) and how does it work?

Accepted Answer

LoTW is an MCP (Model Context Protocol) server designed to integrate with ARRL Logbook of The World. It allows you to programmatically query valuable amateur radio data like QSO confirmations, DXCC credits, and user activity directly through any MCP-compatible AI assistant.

Question 3

What specific LoTW data can I access with this tool?

Accepted Answer

You can query confirmed QSLs using comprehensive filters (band, mode, call, date), access all uploaded QSOs (both confirmed and unconfirmed), retrieve DXCC award credits, and monitor LoTW user activity, including account usage and last upload dates.

Question 4

Do I need to provide my LoTW credentials to use all features?

Accepted Answer

Most data queries, such as for QSLs, QSOs, and DXCC credits, require your LoTW credentials for secure access. However, the `lotw_user_activity` tool can be used publicly without any login to check if a callsign uses LoTW and their last upload date.

Question 5

Can I upload QSOs to LoTW using this tool?

Accepted Answer

No, the LoTW tool is designed to be read-only. Uploading QSOs to ARRL Logbook of The World requires TQSL digital signatures and is out of scope for this particular integration.
