This is my homepage where I write about my opinion, projects, things I note, things I try and other random stuff. Newsitems have tags for a bit of structure. Trying FT8 on the 2 meter band. The different radio bands also have quite different properties. The HF bands below 30 MHz have ionospheric refraction which lets the signal return to earth in far away places.
