Add the MCP server above, then paste one of these. Each one runs on our free live tools today. You get real recordings and daily data from volunteer networks, not live control of a telescope or an antenna.

01What is the ISS transmitting?

Look up the ISS (NORAD 25544) in SatNOGS. Which of its radio transmitters are still alive? List each one's downlink frequency in MHz and its mode.
