How to use radio/radio modems to communicate with random people? (lemmy.ml)

You know how sometimes in a show or a movie there is a character that has a "radio friend" that they talk to? Yeah that's what I want to do.

But I do not know how to so I came to ask you! Cheap, preferably.

Out of curiosity, I found this app on IzzyOnDroid, (which gave me the idea in the first place) Codec2Talkie that seems to be what I'm looking for but I'm unsure due to my ignorance.

A radio modem seems to be required as the app description dictates. I can find one somewhere no issue. But is this the correct approach? Is there a better way that I don't know of?

Does it have to be audio? A meshtastic radio like what you get from https://www.lilygo.cc/collections/lora-or-gps will pair to a smartphone app (or browser app) and let you text with people who also have a meshtastic radio nearby. If you're in a reasonably dense area there may be several people chatting.

I can't recommend meshtastic enough. I have 2 radios and I get to chat with other like minded folks over off the grid encrypted p2p 100s of miles away.
