How it Works

This page is a work in progress


All commands are sent via APRS message to ARMDS.


Get current weather conditions for your location, a city, or a grid square.

Get current weather conditions for your location.

Example - @WX

Get current weather conditions for a city.

Example - @WX seattle

Get current weather conditions for specific grid square.

Example - @GRIDWX DN97vt

Maidenhead Grid Square

Give your location as a maidenhead grid square. Find the maidenhead grid square of another APRS station.

Get your last known position as a maidenhead grid square.

Example - GRID

Example - @LOC N0CALL-7

Find name and city of US callsign

Find out the name and city of a licensee via APRS.

Example - @CALL n0call


Anytime a message is received with the post command (@P), a new post is created. Posts are sorted by callsign(without APRS SSID). For example, N0CALL-7 becomes N0CALL. A tag is assigned to each post with the callsign and SSID to allow sorting by specific APRS stations. See tags.

See User Posts for list of posts by callsign.

Each post is assigned an ID. This ID is used for retrieval of post via APRS and for deletion command.

Any user can post and retrieve via APRS message.

Please note that all commands are case sensitive. Also note the spacing is sensitive as well.

When adding a custom ID and Title, @T must come before @I in the APRS message, see below.
