The best way to learn (or re-learn) Morse code is to assign yourself several time periods a week and just sit down and listen to c.w. broadcasts or tapes while you write down the characters you can understand.(2 way radios range)

If you are starting from scratch, there are many free computer programs you can get that will teach you Morse code, a few characters at a time. It is normal to start with the alpha characters (A B C etc) and then learn the numerals ( 1 2 3 etc) and finally the prosigns and punctuation characters.

If you already know them, but just wish to increase your speed, all you have to do is listen and write down, again and again and again. The skill comes from reading the morse code.

Sending ‘charley whiskey’ (c.w. – ‘continuous wave’ signals = Morse Code) is much easier than reading it, and can be learned after you can read c.w.(2 way radios range}

You start at START and hear a DAH then move down and left to the T and then you hear a DIT so you move down and RIGHT to the N and then you hear another DIT so you move DOWN and RIGHT again and land on the D
You then write down the letter D on your code copy paper and jump back to START waiting for your next letter.
The key to learning the code is hearing it and comprehending it while you hear it.
The only way to get there is to practice 10 minutes a day.
Listen to code tapes or computer practice code while tracing out this chart and you will find yourself writing down the letters in no time at all without the aid of the chart.
The chart brings repetition together with recognition, which you don't get from any other type of code practice aid.

In what conditions can a two-way radio deliver its maximum range rating?

A. From a high vantage point looking down into a flat valley or lowland area with minimal tree cover. Flat, obstruction-free settings are also good for transmitting radio signals, but the addition of height greatly boosts your range potential.

2 way radios range

One example: a large lake with nearby hills — a setting where two-way radios are often tested. During such tests, three or more radio users may be deployed around a lake:

On a boat
On the lakeshore
On a hilltop several hundred feet high

Depending on what type of radio is being used, the boat and lakeshore users can typically communicate at distances of 4 to 6 miles. The hilltop user and the boat use can potentially hit the top of a radio's range (if the lake is large enough and distant topography does not interfere).

From high vantage points — say, a 1000' hill in the vicinity of a population center located below in an open valley — you may find a radio has too much range. It's possible you'll hear people talking on every channel. In such an ideal situation, even a half-watt radio could send its signal 25 miles or more.

Ultimately, a key rule for optimizing coverage is achieving good line of sight. You will increase your ability to increase your range as you increase the elevation of your position. Attaining a high point above an otherwise flat area can be a huge benefit toward optimizing your radio's maximum range.

Radio waves travel longer distances when emitted from higher elevations, which is why high points near major metropolitan areas (such as Mt. Wilson near Los Angeles) are popular places to erect radio and television transmission towers. High-elevation transmission locations help radio signals overcome impediments and even the curvature of the earth.

What types of 2-way radios are available?(2 way radios range)

Want to stay in touch with your skiing pals dispersed all over a mountain? Need to check in with hiking partners traveling at a different pace? 2-way radios range — rugged, lightweight, compact — are designed for such tasks.

How well do they work? Here are some tips to help you set realistic expectations and decide which model is right for you.

Q: What types of 2 way radios are available?(2 way radios range)

A: You can choose from two configurations:

1. FRS (Family Radio Service) models — lower-power units that operate with a half-watt of power. They can transmit on 7 FRS channels and 7 shared FRS/GMRS channels (channels 1-7) — a total of 14 channels.

2. GMRS (General Mobile Radio Service) — higher-power radios that, for models used in outdoor recreation, typically offer 1 or 2 watts of power. GMRS signals can travel on any GMRS or FRS bands — a total of 22 channels.

Most radios now have all 22 FRS and GMRS channels available. The Federal Communications Commission (FCC) requires a five-year license to use GMRS bands. More details about these two types of radios can be found later in this article in the "Channels and Privacy Codes" section.

Q: Range claims ("Up to 25 miles") are often prominently displayed on packaging. How realistic are such claims, and how important are they?

A: High range claims are based on transmissions in optimal conditions. This means having an unobstructed line of sight between you and another radio operator, preferably from a high vantage point in good weather.

Real-world conditions, though, are usually not optimal, and the range of a two-way radio is commonly much less than the maximum possible.

So what is realistic? Regardless of a unit's published optimal range, in roughly 90 percent of situations (including activities in wooded or hilly terrain), a radio's actual range will be about 2 miles or less.

Why? Several factors can inhibit two-way radio performance:

Topography (hills, deep canyons, ridgelines, tall formations)
Weather (such as thick clouds)
Electromagnetic interference (lightning)
Obstructions (dense forest, structures)
Large metal surfaces (inside a vehicle, range is usually less than 1 mile)

The human body (which is dense and watery) can also block radio waves. You may boost reception of incoming signals if you attach a radio to a section of your pack that remains away from your body instead of clipping it to your belt.

Potential causes of radio interference are as random as nature itself. So yes, your two-way radio results may vary.

While dense forests or multiple ridgelines can be major impediments to radio signals, scattered trees and bushes are mostly transparent or "translucent" to these signals. So even in forested or hilly territory, two-way radios generally do a fair to good job of transmitting short-range signals.

A chief benefit of higher-powered radios (1- or 2-watt models) is their ability to fill in coverage dropouts (behind hills or buildings, for example) that often occur within the line of sight of a radio user. The higher power tends to improve the overall quality of the signal.

Even so, for people who typically use their radios in fairly compact areas — a ski resort is a good example — a lower-power unit could serve your needs quite adequately.

Which Two-Way Radios Rance Is Best For Your Business?

2008-11-08T04:14:00.000-08:00

Today's businesses have discovered an easy and inexpensive method for increasing their bottom line.

Radios that can receive and transmit communications are known as 2 way radios. Some common examples are walkie-talkies, CB radios and even cellular phones. While these products are very different in nature, they are common in that they receive and transmit communication and are classified as 2 way radios rance. There are many uses for 2 way radios, including a camping trip with the family where walkie talkies help everyone to stay in touch. When in the wilderness, a cell phone is not likely to have a signal and this is why walkie talkies are so helpful.

But Which Two-Way Radio To Choose...

There are many 2-way radio models to choose from, depending on the needs and requirements of your business. Before purchasing any walkie-talkies, consider these four features: frequency, power, channels, and the durability of the handsets.

Frequency--UHF or VHF?

Consider your environment when choosing which frequency you'll need. If you're communicating inside a building or where there are obstructions between radios, then a UHF 2-way radio is best. These radios work well for businesses such as restaurants, hotels, health care facilities and schools.

VHF two-way radios range work well when used outside on open land or rolling hills with few trees. Businesses such as farms and ranches, golf courses, and survey crews appreciate the reliability of VHF radios.

Power--How Much Do I Need?

Business radios vary in power from 1 watt to 5 watts. While the more powerful radios will communicate at the higher distances, often that power isn't necessary. If your business communication area is under 200,000 square feet or less than one mile in distance, then a 1-watt radio will work well for you.

If the range is among multiple buildings, up to 250,000 square feet in an area, or up to 2 miles in distance, then a 2-watt radio will work. When communicating up to 300,000 square feet and up to a 3-mile distance, a 3-watt radio will do the job. Always consider the range or distance you'll be using the radios to determine the power you actually need.

Channels--How Many Are Really Necessary?

The number of channels available on 2-way radios range varies with each model. If all your employees need to communicate with each other, then one channel works well. However, if you operate a business such as a hotel, you'll want multiple channels. Then your kitchen/wait staff, housekeeping, and valet service each can stay in touch on their own channel.

Determine how many different departments will be communicating among themselves and across departments when deciding how many channels your radios need.

Durability--How Sturdy Must My 2-Way Radio Handsets Be?

How and where the two-way radios will be used determines the ruggedness needed in handsets. If you'll be using the radios outside where they could get knocked around a bit, then you'll need a sturdy model. If the two-way radios will be used inside an office building to communicate from floor to floor, then a less rugged model will work well.

It may be best to choose a consumer radio in a light-duty situation where very little range is needed. This would allow you to get away with only using the FRS channels and avoiding the license fees. A great example is a school that needs radios for directing traffic in mornings and afternoons.
