M17 reflectors and modules, free.
Pick an M17 reflector and a module letter, and talk, with no password to set up.
What M17 reflectors are
M17 reflectors are internet servers that link M17 stations. Each one is split into modules named by letters, each a conversation of its own.
The app connects with the callsign on your account. Moving to another module is one tap in the module list.
