Amateur Radio Repeater on the International Space Station

---

There is an Amateur Radio Repeater on the International Space Station that is open for use by all hams.

You will need to use your computer or smartphone to track the ISS, so you know when it is going to be “overhead”, so that you can use the repeater.
