Unlicensed Radio
Radios are now walkie talkies
This is the era of new inventions, technology and science. Every day we hear about new inventions. People are now become more conscious about what to buy and what not to buy. They want everything up-to-date and latest. They look for style as well as their ease.
Living in 21st century, everyone wants to be aware of the new technology present in markets. Walkie talkie radios are one of the best examples latest developments in the field of technology. Walkie talkie radios are very portable because they are hand-held and can easily be fitted in one's hand or pocket.
These radios are commonly used in offices, work places and private sector. These radios are popular among people of every age group. Walkie talkie radios are used to send and receive messages as well. It is very useful for remote activities as it doesn't need any cell sites. This makes it easier for people connect with their friends and family.
Walkie talkie radios are of two types; namely licensed and unlicensed. The licensed type radio walkie talkie is more useful as it has more functions than unlicensed radio. Usually licensed walkie talkie radios are used by business class people whereas unlicensed radio walkie talkies are used by youngsters just for fun purpose.
Walkie talkie radio uses two types of service mainly. They are named as FRS , which is a family radio service and GRMS. The FRS is an unlicensed radio service which is just efficient for fun sake and limited to listening music and such types of activities. On the other hand, GRMS is best for business use. It is expensive than FRS but more efficient with more functions that are not available in FRS.
To make the walkie talkie radio work better, one should take care about many factors. Distance is one of the major factors. FRS and GRMS radio walkie talkie work at a specific distance. It is 2 miles for FRS and GRMS can usually accommodate up to 5 miles. Other factors that can affect the performance of radio walkie talkie include location, height and range. Therefore these factors should be kept in mind while using it.

What job title would a GMDSS maintainer in the Merchant Marine officially hold?
I'm a little confused as to who actually works as a GMDSS radio maintainer. To satisfy the requirement of at-sea maintenance, it's obvious that SOMEONE aboard has to hold the license to perform maintenance on the GMDSS equipment, but I can't figure out who that person would be. Someone from the engineering department? Or maybe one of the deck officers...? Help!
Also, if you know the answer to this one... To operate the GMDSS equipment, you have to have licensing through the FCC. But from what I've been reading, it seems like -anyone- can use it. I know that (except for Military Sealift Command) there isn't a designated radio operator, but would an unlicensed crewmember with no radio operator license be allowed to operate the radio? Or is it ONLY proper for licensed crew to perform radio communications using GMDSS equipment?
Sorry for the barrage, but I'm having a hard time finding answers!
A GMDSS maintainer would be called the Radio Operator. That's the job title- realistically, you have to have a good knowledge of computer networks, electronics installation, and how to change the settings on the captain's TV, because that's what the radio operator mostly does.
Larger shipowning companies have a couple of radio operators in their fleets, and they play musical ships, jumping between vessels on both an as-needed and regularly-scheduled basis.
The only people who operate the GMDSS system are the captain and the officer of the watch (in a limited fashion). As you're aware, no one wants unnecessary traffic, and an extra warm body sitting at the GMDSS station while the captain and the OOW are walking the bridge is annoying. Modern GMDSS sets are almost idiotproof, anyhow, requiring little more than knowledge of how to send and print emails, spoof the Alarm system so that the idiot arabs and their love of false distress calls don't drown out the VHF traffic, and trying to keep the bridge quiet to allow the man on watch to focus on what's out the window vs. 3,000 miles away.
