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?

like ham radio? i think you can find affordable radios to listen, but in order communicate i recall you need like a radio communication license. at least in the USA

You need a ham operators licence and it requires a test and a whole bunch of knowledge

It's mostly stuff you definitely need to know, though, at least in Canada. There's a bit more to it than sending a text.

I think you misread test as text

[–] CanadaPlus@lemmy.sdf.org 2 points 1 month ago (1 children)

No, I wasn't quoting anything there. People are used to choosing who they want to communicate with, sending a message, and everything either working or (rarely) not working. Power, noise, space weather, multipathing, interference and the vagaries of antenna performance all make it a bit more involved when manually operating a radio. And that's not even getting into whatever you need to make your own setup work.

Oh I see, you were comparing the two rather than quoting me, my mistake
