Solar and geomagnetic measurements give context for HF reception. They do not confirm a band opening or measure the station’s antenna.
THE STATION
Listening, decoding, sharing
The satellite capture host
Muninn records scheduled satellite passes and processes the received signals into weather images or ISS channel recordings. Reception depends on the antenna, pass, and what is transmitting.
Real received images
The gallery shares processed satellite captures from the station. False-color images combine sensor channels, and partial scans are labeled so gaps remain visible.
