The *SPACE* Amateur Radio over Internet Protocol (RoIP) systems stream public audio transmissions from Mission Control and Astronauts for educational purposes. Connect via EchoLink to the *SPACE* conference, via IRLP to the 0100 experimental reflector or via Allstar to node 516221.
Transmissions primarily originate from NASA public media sources. The ISS public audio channel 2 feed is usually enabled, which is mostly english communications. ISS transmissions seem to occur mostly during early mornings USA time, since the ISS mostly operates on the UTC timezone. Other special events, such as launches or space walks, may also be included. Refer to www.nasa.gov/nasalive or www.spacex.com/launches/ for schedules.
- Expect long periods of silence. As noted, most ISS communications occur during early morning USA time. Also look for activity during special events scheduled by NASA, SpaceX and others.
- NASA and other audio sources are sometimes unavailable, unreliable, noisy or their content changes. That may result in audio being unavilable to this service periodcially.
- IRLP node owners must enable experimental node access by editing the custom/environment file to include the line:
export ALLOW_EXPERIMENTAL_NODES=YES
- Allstar nodes should connect to node 516221 using MONITOR mode. Allstar nodes that transmit will be disconnected automatically.
- No conferencing or communication is provided between connected nodes. Transmissions from EchoLink and IRLP nodes are automatically muted.
- Echolink connections utilize the GSM CODEC. IRLP and other connections default to the uncompressed or u-law CODEC, which "may" provide somewhat better audio fidelity or quality compared to EchoLink.
- Some musical tones may be included on NASA and other transmissions. We attempt to only use public mission control audio sources which minimizes music and media content.
- The transmissions are activated by a VOX interface. The system attempts to interrupt excessively long transmissions. However, some transmissions may exceed your transmit time out timer.
- Recordings of transmissions are published at spacerecordings.rfnet.link.
- This is what the ARRL references from the FCC and NASA about Can I re-transmit communications on the ham frequencies? Rules and guidelines may differ for other countries.

Change Log
- February 5, 2023 - NASA ISS Mission Control audio volume has been very low and noisy for several days. I have attempted to filter and compensate.
- September 1, 2022 - Initial release of space.rfnet.link
