Tim is making the argument that "real radio" is very personal, just like music.
Starting with a mention of echolink, connects repeaters and can be accessed from the pc or your phone too. RF still very much involved.
International Radio Network now, uses teamspeak to connect with RF (requires license) and non-RF (for anyone) which can be a great introduction to the hobby.
Zello. Various users and uses, from the noble to the questionable. Some RF links, eg to Southern Ireland repeaters. Active!
