Hi all, When our Limited License scheme (no CW requirement) was introduced in about 1970 here in Australia, and lots of us were city workers, VHF FM in our cars was a new thing and repeaters helped a lot. It's about being involved.
The ionosphere does bounce signals back to earth but, not to where I want!! Repeaters on VHF require high site locations, not always possible. So if my signal only goes upward at 10 deg at the lowest, I need either a satellite OR a repeater somewhere, at the skip distance away. Oscar 7 can give me perhaps 10 mins per day. My 2c.
