Satellites and the international space station

• The International Space Station contains a digipeater!
• ISS and OSCAR digipeaters operate on 145.825 MHz.
• Trivia: OSCAR stands for Orbiting Satellite Carrying Amateur Radios
• The WIDEn-N path does NOT work on satellites, you must use ARISS or RS0ISS (for the ISS only)
• It is not unusual to have packets heard by stations across the United States in a single hop!
• Astronauts onboard the ISS have been known to reply to messages sent to RS0ISS.
