ISS listening

Novelty sidecar — not the Kiwi

The KiwiSDR covers HF only (up to 30 MHz). Amateur radio on the International Space Station uses VHF/UHF.

Crew voice and SSTV downlink: 145.800 MHz FM (receive only — do not transmit here)
FM repeater downlink is often on 70 cm (verify current ARISS frequencies before a pass)

A dedicated 2 m antenna and a small SDR will feed this page later. Pass times will be computed from daily TLE data for the Eureka horizon.

Next-pass widget: not installed yet. Audio: not installed yet. This page is the placeholder so the menu is stable.

When it is live

Expect short passes (several minutes), not a 24-hour ISS channel. The site will say when a pass is due and when the downlink is actually being streamed.

EurekaSDR is not an ARISS or NASA station.
