Which Two Way Business Radio is Right for My Restaurant?

!: Which Two Way Business Radio is Right for My Restaurant?

Choosing the wrong 2-way radio for your restaurant, which can include choosing the improper frequency band, the wrong number of channels or insufficient power level can be like throwing money away. Because of the sizable investment involved, you and your employees could be forced to live with a two-way radio error for years. Instead, be certain to select the right radio for the job.

One of the worst moves would be to purchase a VHF radio. The difference between UHF and VHF can be explained with frequency penetration. VHF waves travel about twice the distance of UHF waves on open ground, rolling hills or through foliage. However, VHF waves are very poor at penetrating walls, buildings and rugged terrain. So, if you are working exclusively outdoors with open land, rolling hills or heavy trees, VHF radios are the best. In any other situation, including indoor to outdoor use, UHF radios will be the choice.

Choosing too much power could be a waste of money for the upgrade, as well as choosing too many channels.

Any standard restaurant will have sufficient coverage with a 1-Watt UHF radio. Any wattage beyond that is not useful, unless you plan to go off site as well. In this case, you may want to look into a 2 or 4 watt walkie talkie.

The number of channels is important as well. Try to think 2-5 years in advance and think about the maximum number of channels you will need. If all of your employees will always be on the same channel, no matter what, then a 1 channel radio is right for you. If, however you need multiple channels, be sure to get the proper number. For instance, say you wanted your car valets on one channel and your wait-staff on another (they have no need to communicated with each other). But, you as the manager want to speak to both groups. Then, you will nee a radio with at least two channels. You will need at least 4 channels if you have 4 groups of people speaking at the same time, same for 6, 10 etc.

Fortunately, Motorola designed a 2-way radio from scratch that is specifically meant for the restaurant industry. It is small and lightweight, but durable and powerful. The CLS series radios solve all of the problems of past radios.

For a single channel CLS, you will want the CLS1110. For up to 4 channels, you will want the CLS1410. If, by chance you need more coverage than a typical restaurant. You may want to look at the XTN radios, such as an XU2100 or XU1100.

Ham Radio's Annual National Contest - Field Day!

!: Ham Radio's Annual National Contest - Field Day!

Once each year thousands and thousands of ham radio operators participate in what some consider to be an annual contest - Field Day. Field Day has a more serious side to it than being just a contest however. I call it a contest because the national organization of ham radio, the American Radio Relay League does actually keep scores for each ham radio station that participates in Field Day. While most hams do want to get their score as high as possible during Field Day the objective is to practice and refine communications skills "in the field".

Many ham radio operators have sophisticated home base stations with large antenna towers and high gain beam antennas. The main objective of Field Day is designed for the portable ham radio operator. The objective is to demonstrate and refine the ability to communicate "in the field".

Once each year thousands and thousands of amateur radio operators participate in what some consider to be an annual contest - Field Day. Field Day has a more serious side to it than being just a contest however. I call it a contest because the national organization of amateur radio, the American Radio Relay League does actually keep scores for each ham radio station that participates in Field Day. While most hams do want to get their score as high as possible during Field Day the objective is to practice and refine communications skills "in the field".

Many amateur radio operators have sophisticated home base stations with large antenna towers and high gain beam antennas. For Field Day those hams are not allowed to use that equipment. Field Day is designed for the portable amateur radio operator. The objective is to demonstrate and practice the ability to transport, assemble and operate their equipment in the field. There are strict rules preventing the use of permanent structures.

Field Day's benefit becomes crystal clear when you consider that many ham radio operators freely provide high quality portable radio communications in disaster situations. Hurricane season is prime time for such communications. Tornado outbreaks also are a time when such communications capabilities become very valuable. The ability to transport and quickly assemble a high quality amateur radio stations and operate it under stress for an extended period of time is exactly what is tested at Field Day. The scores that are obtained in the contest are roughly indicative of the performance described above.

Is Field Day all work and no play? Usually not! Hams can do Field Day alone. Large numbers of ham amateur radio operators participate as a group. In Appleton Wisconsin and in Green Bay Wisconsin the local ham radio clubs host group events. In each event there is some form of shelter provided. Different members bring their ham radios of various types, computers for digital mode communications, antennas and of course food and drinks. Events such as these are a great time for amateur radio operators to get to know each other and trade stories of rare radio contacts and operating experiences.

Field Day contest points are scored by contacting other ham radio stations. The person or group that makes the most contacts on the most frequencies typically wins the contest. The results of the contest are published in QST which is the monthly magazine of the national organization for amateur radio operators. Being published in a monthly magazine provides bragging rights for those that win the contest.

While winning the contest is a fun achievement it proves that the amateur radio operator that won the contest is quite skilled at making a large amount of contacts over a 24 hour time period. Information must also be exchanged and then accurately reported by both radio operators for the points to be scored. This represents the ability to exchange large volumes of information in a high stress event like a disaster. Tune your radio to the ham radio bands on Field Day each year and find out just how many people participate in this event. To find the specific day of the event or to find an event near you that is open to the public search Google or other search engine for "field day open to public" without the quotes. I know that the amateur radio clubs in Green Bay Wisconsin and Appleton Wisconsin would love to have visitors!

Uses of Radio Communication

!: Uses of Radio Communication

Radios are one of the first types of communication to be invented that are still used in the modern age. The main reason for this is because of the ease of use and the low cost it takes to use it. They are a very important component of many businesses such as the construction industry.

In the construction industry the person operating the crane is very high up and most defiantly out of reach of and site manager giving the instructions below. Some people might suggest the use of mobile phone for communication but the cost per day would be too high for it to be a viable option. Instead you can use a radio for communication as it would be very cheap, in fact all it would cost is the initial price of the radio sets at the shop. If you do decide to buy a radio set then make sure that it is rechargeable as buying multiple batteries per week for the use of the radio is also very expensive.

When in pursuit of a criminal the police use radio communications in order to coordinate themselves around the suspect in order to increase their chances of catching him. It can also be use for calling for backup and is one of the first things that are used when a dangerous situation occurs. This just goes to show how important these devices are for this type of job, without them many different produces would have to be changed in order to get the job done to the same standard.

How to Use 2 Way Radios

!: How to Use 2 Way Radios

A 2 way radio is basically used for two way communication. These radios are used in various applications mainly for the purpose of communication. These can be used in military organizations, in businesses, in hospitals, in shopping malls and for outdoor adventures.

This type of a radio can be used either in duplex or simplex mode. When a 2 way radio is used in a simplex mode, the communication can take place from only one side. This is very much like a telephone conversation where a user dials a number, waits for the other user to pick up the phone and then starts speaking. Almost the same happens in simplex communication. A radio first locates another one to which the data has to be sent. Once this radio has been located, the message is transferred over a single channel. When the other radio receives the message, it responds to the message by sending some data over the same channel that was used for sending data.

The other mode used for two way communication by a 2 way radio is the duplex mode. In this mode, data is sent and received at the same time over different channels. When one user locates another one, both can transmit data at the same time by using two different channels. This mode of transmission is a better mode as large data can be transferred at any given time.

When these radios are transmitting data, there might be times when they pick up noise or messages from other locations. When this happens, the message is not received clearly. There may also be times when a static frequency is picked up by the radio and the radio cannot transmit for that period of time. These problems have to be overcome so that messages can be sent and received clearly. This can be done by making use of various accessories that eliminate the noise or extra signals that the radio might have picked up. One way is to use hearing aids so that the message can be received clearly. Another option is to use induction loops in which messages can be sent by eliminating the noise. Yet another way of ensuring that these radios can be used for clear transmission is by using assistive listening systems. 2 way radios can also be used more effectively by using sound suppression techniques.

When 2 way radios are used in organizations where there is a lot of noise, it must be ensured that all sound producing elements are either removed or techniques must be used to suppress the noises. Also it must be ensured that the radios operate in a vibration mode when they are used in offices. When these radios are used in factories where noise level is very high, sound absorption panels must be installed so that the transmission of data takes place in a clear manner. Noise filtering can also be used to eliminate the extra noises or signals that have been picked up by the radio. Also one must try and use digital transmission when using the 2 way radios as this ensures that the data that is transmitted is very clear.
