2 Way Radios and the Information You Need to Know
Anyhow ladies and gentlemen, i’ve another excellent radio earpiece piece of writing to read, i know, you do not have to thank me all, just click a social like to the piece to prove your appreciation.
A 2 way radio differs from a broadcast radio in the sense that it can receive as well as send messages and can be used for communication between two people. These types of radios are available in several different configurations. These include the hand held radios, mobile radios and stationary base radios. These radios can either operate in a full duplex mode or a half duplex mode. In the full duplex mode, these radios can be used for both sending and receiving data at the same time over different channels.
In the half duplex mode, these radios can be used for either sending or receiving data over a single channel. There are various things that one needs to know about the 2 way radios . These radios are very compact, are light weight and are available at a very affordable cost. These radios are available in different styles and are used for a large number of applications.
These radios generally have a push to talk button that make it very convenient to use and easy to handle. These radios are available with either rechargeable batteries or replaceable batteries. These batteries can either be made of nickel and cadmium or of lithium ion.
The 2 way radios operate in different ranges. The range specifies the distance that can be covered by these radios for communication. These radios can operate over short ranges or long ranges. This depends upon various factors like the frequency, the type of terrain etc.
Most of these types of radios operate in line of sight frequencies. This means that they cannot work well in hilly areas and in places where there are obstructions. These radios come with a large number of features. These radios are even made compatible with computers so that they can be used for sending data from one computer to another computer.
Another thing that users must know about 2 way radios is that these can even be used for hands free communication as these are available with handsets. These radios may or may not require licenses for their use. When these radios are used for personal purposes, the need of licenses does not arise.
If these radios are used for the purpose of business or in organizations, then the users need to obtain licenses for their use.
The 2 way radios operate on different channels. Since these channels are open, anyone can listen to the communication or intercept the messages being sent. To prevent this, these radios come with a privacy code. Also most of these radios are provided with scanning functions so that the channels can be automatically scanned for and manual setting of channels is not required.
These radios can be purchased from stores that deal in electric gadgets or can be bought online. The internet is the best place to buy these radios as a user can compare the various types of radios available and then choose the best one. This ensures that the user gets the best deal and does not end up purchasing a radio that does not satisfy the requirements of a user.

How does bone conduction work? Asked by Mike from Nebraska, USA
I don’t know if you came here because you read it on social media, twitter, facebook, google +, stumble upon or somewhere else. But thank you for visiting and I trust you enjoy reading this as much as I did.
Hi Mike,
Bone conduction headphones (commonly referred to as ‘Bonephones’) are actually really clever. In order to best explain how they work, I’ll need to take you on a journey into the Human ear…
No, not literally. That would be disgusting.
OK, so you know how sound travels through the air? Surely you must have done that science experiment at school where you hear sound disappearing into an airless vacuum? Yup, it’s just like that.
Anyway, the sound waves come into contact with your outer ear structure, or pinna. Then, the sounds pass into your middle ear, which is filled with air (obviously). The sound travels through your auditory canal and then your eardrum. Your eardrum then vibrates, an action that passes the sound to your ossicles.
Now, the ossicles are three tiny little inner-ear bones and their job is to translate the sound to the cochlea, a fluid-filled structure that in turn ‘encodes’ the sounds in order for our brains to ‘decode’ and process them.
It’s actually quite a ride, when you think about it.
So, bone conduction headphones bypass the pinna, the auditory canal and the eardrum and take the vibrations directly to your ossicles, quite literally rattling your bones. From there, the ossicles transmit to the cochlea and the process carries on as usual.
That’s basically it.
It is actually a good way to listen to music if you have hearing problems and it has the added bonus of being effective whilst the listener has earplugs in, or even when he/she is underwater.
I had my doubts about the safety of this technology when it was first announced, but it has been out a while now and has been pronounced as safe by medical experts. In all probability, bone conduction is actually better for your ears than regular headphones are.
To quote, um, myself, in an article I published a few months ago:
“According to recent studies, exposure to any noise over 100 decibels wears away a membrane known as the myelin sheath and leaves your inner ear susceptible to problems like tinnitus and temporary deafness, which can be the beginning of even more serious problems. Bone conduction technology has been designed to bypass the most sensitive portions of your ear and reduce the risk of inner-ear damage”.
