What can block radio signals?
Thin amounts of plastic wrap, wax paper, cotton and rubber are not likely to interfere with radio waves.
However, aluminum foil, and other electrically conductive metals such as copper, can reflect and absorb the radio waves and consequently interferes with their transmission..
Can astronauts hear each other in space?
When astronauts are out in space, they can whistle, talk, or even yell inside their own spacesuit, but the other astronauts would not hear the noise. In fact, the middle of space is very quiet. Sound travels in waves, and it moves at different speeds through air or water or other materials.
Are walkie talkies traceable?
No they can not be traced, unless they have a GPS chip in the radio. No they can not be traced, unless they have a GPS chip in the radio. However, any radio signal can be direction found and triangulatied. In the ham radio community We actually make it a game it’s called Fox hunting.
Can a radio signal be traced?
A tracking transmitter broadcasts a radio signal which can be detected by a directional antenna (typically a Radio Direction Finder.) By rotating the antenna one can determine the direction the signal lies in and of course whatever it may be attached to. The EPIRB is an example of a similar device.
Can a phone communicate with a walkie talkie?
Hello there, Technically that would not be possible because both the devices uses different frequency bands all together. that means a android phone cannot tune to frequency of a walkie-talkie and vice-versa.
Can humans pick up radio signals?
Yes, humans, under special circumstances, can hear radio-frequency pulses in the range of 2.4MHz to 10GHz (corresponding to radio frequencies and microwave) as buzzes, clocks, hiss or knocking at apparent auditory frequencies of 5kHz and higher (very high-pitched).
Why can’t Two astronauts hear each other in space?
No, you cannot hear any sounds in near-empty regions of space. Sound travels through the vibration of atoms and molecules in a medium (such as air or water). In space, where there is no air, sound has no way to travel.
Can walkie talkies pick up police?
The police are not on any channel on any ‘walkie – talkie’. They have their own frequencies that vary from place to place, and are on a band that only they are allowed to transmit on.
Do astronauts use walkie talkies?
Yes. Walkie Talkie’s use radio energy which does not need air or an atmosphere to work. This is why Astronauts and Space Probes can communicate back to Earth. It’s also why radio astronomers such as SETI can listen to outer space.
Is the BaoFeng illegal?
It is illegal to transmit using a baofeng without an amateur radio license. Almost all Baofengs ARE NOT type approved for FRS/GMRS frequencies. … Baofengs are technically capable to transmitting on FRS/GMRS frequencies but not legally.
Can you talk to each other in space?
Sound is vibrations of air particles, so any “sound” that is heard in space has to come from other means such as from the electromagnetic spectrum and these waves are not sound. … Light waves are not sound waves. Astronauts can however, talk to each other as if they were on Earth only when they are in their space ship.
Can police tell if you are listening to scanner?
Most police vehicles come with scanners now as well so they can monitor other agencies.. and besides, most places dont mind scanners. now if your commiting a crime and listening, then thats another story.. So basically, they cant do everything without someone noticing..

What does 10 4 mean on a walkie talkie?
10-4 = Message received. 10-5 = Relay message to ___ 10-6 = Busy, please stand by. 10-7 = Out of service, leaving the air. 10-8 = In service, subject to call.
