What is quiet talk on two way radios?
Quiet Talk is achieved through the use of a Continuous Tone-Coded Squelch System or CTCSS. This is a circuit that is used to reduce the annoyance of listening to other users on a shared two-way radio communications channel. It is also sometimes called tone squelch. Where more than one user group is on the same channel (called co-channel users), CTCSS filters out other users if they are using a different CTCSS tone or no CTCSS.Receivers equipped with a CTCSS circuit usually have a switch that selects normal mode or CTCSS mode. When enabled, the CTCSS radio circuit, instead of opening the receive audio for any signal, causes the two-way radio receiver's audio to open only in the presence of the normal RF signal AND the correct sub-audible audio tone (sub-audible meaning that the receiver circuitry can detect it, but is not apparent to the users in the audio output). This is akin to the use of a lock on a door. A carrier squelch or noise squelch receiver not configured with CTCSS has no lock on its door and will let any signal in. A receiver with CTCSS circuitry (and with it enabled) locks out all signals except ones encoded with the correct tone. CTCSS can be regarded as a form of in-band signaling.

Dr. Mahlom Loomis invented the first radio. He was a dentist in Washington D.C. In 1865 he sent 18 kites miles away from each other on the West Vriginia mountain. He rec…ived connection. He did this so that when he was not home he could still here the news. Congress awared him $50,000 research grant. Dr. Mahlom Loomis invented the first radio. He was a dentist in Washington D.C.

Range and that the communication is not private, anyone can listen in.
Two way radios are simple ways of staying connected wirelessly. Though they cover only a limited area, the cost-effective quality of the radios keeps them far above the other …means of communication. The best thing about the radios is that there is no per minute call charge. This means that you will not need to pay any network provider for the time you talk on the radio. Once you a buy a set, it will keep on giving you service.
hey how are you?....etc
You can use them to communicate with other people when you need to. Example: A cellphone is a two-way radio.
Yes, it is possible to use direction finder devices (usually radio receivers with directional Antennas abbreviated to "DF receivers"), the most common and oldest method is tri…angulation of the the two way radio signal by two and ideally three DF receiver stations, these will compare results and they will be able to locate a two way radio device quite accurately as long as it is transmitting reasonably continuously. At VHF & higher frequencies there are direction finders that use a special antenna array on top of vehicle and use methods to detect the Doppler effect by doing timing comparisons of the received two way signal by switching the receiver to different positioned and phased antennas and the results from the receiver detected pass through a signal processor which can process and and indicate the origin of a two way signal with reference to the DF receiver antenna array position and display it on a screen. Cell phones locations are detected in a similar way by using various cell sites and special processing Software to get an accurate fix on the cell phone position.
Not so complicated as that. Your walkie-talkies will work anywhere. However, when you are in port, your use of the particular spectrum (radio bands) that you are using is gove…rned by the rules of that country, not the rules of the ship.
Two way radios can be purchased in any hardware or audio store. You can also find them at stores such as Best Buy, Future Shop, Canadian Tire and Walmart.
Do not use it.
Two way radios have both a transmitter and a receiver so that they may send and receive signals beween units, in both directions. They operate on assigned frequencies within v…arious areas of the radio bands, or spectrum. When a receiver is assigned to operate on a specific frequency, it ideally would just receive that frequency alone. It would be perfectly selective and only receive signals on that assigned frequency, and reject all others. But no device is perfect, therefore it receives 'mostly' on the assigned frequency, and somewhat on the frequencies adjacent to the one assigned. Thus if there is an unwanted signal on a frequency nearby the desired one, it will also be received, but to a lesser extent than the desired signal. (this assumes they are of equal strength). This undesired reception of adjacent signals is one form of interference, and the stronger that undesired signal is, the more it may tend to disrupt reception of the desired signal. There may also be signals on the exact same frequency as your desired signal, and depending on the relative strength of the desired vs the un desired, interference may occur. Best Regards, Bill
It is possible for other people to overhear the message.
It a radio which can both send and receive. You can hear someone else in them, and they can hear you.
Two way radios are used to transmit and receive. What I mean by that is a two way radio allows two people to talk to each with similar devices on the same radio frequency. It'…s rather unique! One (the operator) can talk, and the other listen. This device allows police officers, detectives, and many other jobs easier.
The Motorola Two-Way Radios are new products produced by Motorola company. Motorola Two-Way radios are used to transmit and receive messages allowing the operators to communic…ate with each other.
There are many retailers from where one can purchase two way radios such as Ebay and Argos which offer a wide variety of two way radios at various prices and specifications.
We found a new model two way radio FPCN10A of Samcom , there is abig Group talk button in the middle of key. And it is said thatthere can be usedfor many accasions . Besides I…ndividal Privatetalk, Pressing GROUP button can talk to all Channels simultaneouslyand can work with desktop intercoms directly; A good system fordelivering announcements, or emergency calls.
