How to make a PC program recognize the presence of a radio wave nearby?
It became interesting, but is it possible? There is a mobile application - a walkie-talkie, I don’t remember the name, it works using the Internet, but I wonder what could be done so that the program recognizes the radio wave and translates it into a signal for the program, who can tell?

Answer 1

You bathe in radio waves, which one do you want?
Buy a radio station (walkie-talkie) and don't mess with your brain.

Answer 2

Answer 3

Ready tuner without problems
SDR - cool, versatile, and you can see where what is being transmitted

Answer 4

You need a radio receiver and a radio transmitter (possible in one device). You can probably find it if you search. Perhaps you can make a receiving and transmitting antenna by soldering a large enough wire into a PCI slot (or any other) and applying a sufficiently large voltage to it. How realistic, I have no idea. But there was such a project on the Raspberry Pi, is it possible to repeat it on a regular computer - the question is.

Answer 5

Very simple.
Radio wave receivers and transmitters are now in all laptops and phones, the most suitable radio standard for this task is bluetooth.

Answer 6

I am aware of all this, that there are a huge number of them, etc., but the question was asked for a reason, maybe I didn’t express the idea correctly, but I can’t do otherwise, in fact, I need a good programmer to work together on an interesting idea

Answer 7

If the idea is interesting, then we can discuss joint cooperation.
Experience - microcontrollers, circuitry, embedded programming, development of communication systems.

Answer 8

I use a USB TV Tuner as an RTL-SDR receiver, this is to listen to what is happening on the air nearby, but you can simply listen to amateur radio bands simply via the web, look for websdr
