How to use the feed

mqtt.pskreporter.info redistributes the live feed of spots from pskreporter.info over MQTT, so you can stream amateur-radio reception reports straight into any client, script, or app. Subscribe to a topic, narrow it to exactly the spots you care about with wildcards, and read each one as JSON. No account and no polling — just connect and listen. The live dashboard further down this page is built entirely from this same feed.

1 Connect

Point any MQTT client at mqtt.pskreporter.info on one of four ports:

:1883 plain TCP  ·  :1884 TLS  ·  :1885 WebSockets  ·  :1886 WebSockets + TLS

All four endpoints →

2 Subscribe

Stream every spot for one station — paste this into a terminal to try it now:

$ mosquitto_sub -h mqtt.pskreporter.info -t "pskr/filter/v2/+/+/Q0PSK/#"

Build any filter →

3 Understand

The spot is encoded in the topic path; + matches one segment, # the rest:

pskr/filter/v2/{band}/{mode}/{tx}/{rx}/{tx_grid}/{rx_grid}/{tx_dxcc}/{rx_dxcc}

Each message payload is one spot as JSON.
