Yes you can; I once picked up a police radio with a cheap little toy walkie talkie. But there is no way to tune it, you just have to wait till it picks up a signal, which is very rare.

Why can you hear the radio on wireless speakers when the radio is not on?
You might be picking up radio waves from another source, possibly a neighbor or a different radio. Some powerful radios or walkie-talkies can interfere with speaker systems.
Where do radio waves occur?
They're found everywhere. When you consider that radio waves are sent out by every radio or TV station, every police or fire walkie-talkie, taxicab dispatcher, Bluetooth device, cordless telephone, garage door opener, cellphone, and smartphone in the world, you start to realize that no matter where you are, the room you're sitting in right now is bathed in the radio waves from a million sources or more.
Does mechinal waves have radio waves?
no, mechanical waves are not radio waves
How are electromagnetic waves different to radio waves?
Radio waves ARE electromagnetic waves.
What is a radio wave?
Radio waves are electromagnetic waves. The radio waves have the longest wavelengths in the electromagnetic spectrum. A radio wave has a much longer wavelength than does visible light. We use radio waves extensively for communications.
How does walkie talkie work?
it uses radio waves
Do walkie talkies use radio waves?
Yes. A good rule of thumb is that if the device has an antenna, it uses radio waves. An antenna would not be needed if it didn't use radio waves.
How douse one crystal conponent know how to reach another one like in walky talky you want answer from N2146X Trust 2695 Recommended super Richard?
The components in an device such as a Walkie-Talkie reach each other through radio waves.
How do walkie talkies work?
Each walkie talkie is a radio transceiver (combined transmitter and receiver). Typically there is a rotary switch to select frequency channel for the transceiver and a button that when pressed switches the transceiver into transmit mode (normally it is in receive mode). Set two or more walkie talkies to the same channel and their users can communicate, if they are in range. The details of how radio transceivers work should be found in books on radio design and/or repair as this requires diagrams, figures, etc. that can't be posted here to fully understand.
I have a toy walkie talkie and attached a 4ft antenna so now I can hear cb radios There is also noise that my friend thinks its military code Could this be from the near by military base?
Military code are really hard to come by they are kept tight so you are probably hering something else. You could be hearing cops. How this happens is the nature of radio, and part of the reason you're not likely hearing military transmissions. Radio waves are openly receivable, and a toy walkie talkie is not going to come installed with tightly tune crystals. This being the case, they will pick up strong nearby transmissions and skip.

Did astronauts use wireless sets to communicate on the moon?
They used their spacesuits to leave the Lunar Module and walk on its surface. The Apollo 15, 16 & 17 crews used a Lunar Roving Vehicle (Rover) to drive on the moon. They deployed mirrors on the surface of the moon so scientists could shoot a laser from the earth and measure the exact distance between the earth and the moon. They left probes to take temperature below the surface. They used Hasselblad cameras to take photos. They used numbered plastic bags to document samples. They used hammer to chip off pieces of large rocks for bringing back samples to earth. They used a raking device to collect small pebbles in the lunar soil. They also used TV cameras so show the people on earth what they were doing.
Why do astronauts use radio while talking to each other in outer space?
when they land , so they can communicate with each other. --- The term "Walkie Talkie" is a colloquialism which refers to a hand portable transceiver. Since every spacesuit is fitted with a hands-free transceiver then it is fair to say that they are always using one when suited up.
How do sailfish communicate with one another?
They communicate by sending off mind waves sorta like talking on a cell phone or walkie talkie.
What are uses for radio waves?
Regular household AM radios pick up stations on frequencies between 550 KHz to 1.7 MHz . . . wavelengths between 176 meters and 545 meters. Regular FM radios pick up stations on frequencies between 88 MHz and 108 MHz . . . wavelengths between 2.8 meters and 3.4 meters. 'Short wave' radios, taxi radios, police radios, CB radios, firetruck radios, aircraft radios, weather radios, satellite radios, toy walkie-talkie radios, cellphone radios, computer WiFi radios, cordless telephone radios, garage door opener radios, Bluetooth radios, 4G iPad radios, and microwave oven radio transmitters all have their own separate frequencies/wavelengths that they operate on, so that they don't all interfere with each other.
