The range estimates are inflated by every manufacturer I am familiar with.
Even with line-of-sight transmission, I have found none that meet the claimed distance under common circumstances.

If you have a friend who is a radio amatuer, you might let him crack the case on one to see if there are any adjustments that could be improved; an 'old dog' would be able to locate the right area in which to look and perhaps tweak something to improve either transmitted power (he should have an instrument that would monitor it for adujstment if not for actual measurement) or improve receiver sensitivity.

The factory is only concerned with function and cost, not performance.

That the Motorola meets its stated range doesn't surprise me; they were long one of the most ethical companies around.
I'm not sure of their honesty today since profit (or even survival) has become more important.

Motorola mj270r no range


Handheld radios talking line-of-sight with no obstacles will communicate approx. 2 miles. When talking from inside a building to outside, you can expect 1/4 to 1/2 miles range. Holding the antenna perpendicular to the ground gives you the best range. Height and placement of the antenna determines range. If you were on a mountain you could talk many miles into the valley below. However, in real world applications, range is limited. It can even be limited by the body fluid of the person wearing the radio on their hip, or blocked somewhat by the metal of the automobile one is riding in.

Channels 18-22 are listed as GMRS channels and may have more power than 1-17. The FRS channels are limited to 1/2 watt. But don't be fooled wattage doesn't equal distance. Higher wattage may give you a little more distance, but mostly it will give you clarity in the fringe areas.

Here is a link to the user guide: http://www.motorola.com/web/Business/Products/ConsumerTwo-WayRadios/Talkabout-MJ270R-Two-Way-Radio/_Documents/MJ270.pdf

A link to Motorola's page about the radio: http://www.motorola.com/Business/US-EN/Business+Product+and+Services/Two-Way+Radios+-+Consumers/MJ270R_Talkabout_Two-Way-Radio_B2B_US-EN

And I see where they are quoting 27 miles*, and go on to say:
*How far can I expect my radios to communicate? The communication range quoted is calculated under optimum conditions, with an unobstructed line of sight. Actual range will vary depending on terrain and conditions, and is often less than the maximum possible. Your actual range will be limited by several factors including, but not limited to, terrain, weather conditions, electromagnetic interference and obstructions.

Unfortunately, we are seldom in idea conditions. Radio-to-radio is going to get you 1/4 mile to 2 miles in real conditions.

What is the range on a cruise ship


Typically most handheld radios have a range of 2 miles line-of-sight. However, obstacles between the two radios can significantly reduce range. On a cruise ship you may not be able to talk through multiple floors. To increase your range be certain to have fully charged or fresh batteries, and also hold the antenna upright, perpendicular to the earth.

Transmission cannot reach even 1/2 mile range in open field.do i have to use amplifier?


No. Your radios should be able to talk up to 2 miles line-of-sight. Some tips which will help you include
1) holding the radio upright with the antenna perpendicular to the ground. This will give you the best range. Tilting the radio to the side can reduce your range up to 2/3s.
2) Keeping the radio up higher on your body. Height and placement of the antenna determines range. A radio can talk as far as it can "see". Even the body fluid of the person wearing the radio consumes some of the range.
3) Face the direction of the person you are talking to. The less obstacles between you and the other user the better.
4) Have fully charged (rechargeable), or new (alkaline) batteries installed. One of the signs of a bad or poorly charged battery is loss of transmit power.

Best regards.

Cannot talk 2 my daughter about 5 miles away in worked earlier in day when we were close. have motorola 350 waterproof model we are both on same frequency big 2 little 5 do u have any answers


Sorry to say, to talk 5 miles conditions would need to be ideal. A handheld two-way radio talking radio-to-radio can talk as far as it can see line-of-sight. If you were on a mountain top you might be able to talk many miles into a valley below. However, in real world conditions you would have many obstacles: hills, building, trees, and even the body of the person wearing the radio. Realistically you could talk up to 2 miles line-of-sight, or 1/4 to 1/2 mile if you are talking in and out of a building.

For best range, you can achieve maximum range by holding the radio upright with the antenna perpendicular to the ground, face the direction you are talking and have fully charged or new batteries installed.

Best regards.

I want to know talk range of Talkabout T5720


Handheld radios generally will talk "radio-to-radio", "line-of-sight" up to 2 miles. Once you start putting obstacles in between the radios you will shorten your range.

Advertising literature will sometimes give numbers such as "5 mile range". While this is possible in ideal conditions, it is not common in real-world situations. HEIGHT and PLACEMENT of the antenna determines the range of the radio. Example: Talking from a mountaintop you could talk far into a valley below, much further than the expected 2 miles. However, if you were to be in an congested city, you may only be able to talk a single city block due to obstacles.

To get the best range, use a well charged battery pack, wear your radio high on your body, and always hold the antenna perpendicular to the ground when using the radio.

1/2 mile range max


Advertising on these models is much like reading about a car's MPG, it must be in perfect conditions. Handheld radios generally will talk "radio-to-radio", "line-of-sight" up to 2 miles. Once you start putting obstacles in between the radios you will shorten your range. Even the body fluid of the person wearing the radio on their hip will absorb some of the range. Talking from inside of a building to outside you might expect 1/4 to 1/2 mile. Good rule of thumb: Height and placement of your antenna determines range. The higher the antenna, the further you can talk. If you are talking from on a mountain top to a valley below you can talk as far as you can see. Increasing Range: Hold your radio perpendicular to the ground, not slanted like you would hold a phone. This problem alone could decrease your range 2/3s. Face the direction you are wanting to communicate. Don't shout CB-style, shouting reduces talk-range. Lastly, use good batteries. This will ensure your transmit capability.

Amout range give not working.


From a radio dealer perspective, 5 miles line-of-sight would be in perfect conditions, with no obstacles and literally line-of-sight. Height and placement of the antenna determines range.

Typically speaking a handheld radio will get up to 2 miles line-of-sight. If you are talking in and around concrete, brick, metal, or in-and-out of a building you could expect only 1/4 to 1/2 mi. Conversely, if you were on top of a mountain and you could see 25 miles into the valley, you could talk as far as you could see with no obstruction.

All this being said, there are some things you can do to make certain you get the best range out of your radios. First, always hold the radio upright with the antenna perpendicular to to the ground (straight up). Tilting your radio to the side can reduce your range by as much as 2/3s. Second, face the direction you are talking. Lastly, wear the radio higher on your body with the antenna upright. Height and placement determines range. (Keep in mind, even your body fluid will absorb part of the range.)

I just bought a motorola em1000r 2-way radio set. Last night they worked, but oly at distances under 2 miles (not 7-20 as advertised). But there was a snow storm. This morning they don't work. Today I am...


You might check your Qt filter setting. Here is a link to the user manual: http://www.giantintl.com/ContentManage/manuals/Moto/EM1000%20User%20Guide%2001-11-08.pdf

These radios have a tendency to remember the last setting they were on, when you turn them on again. As far as range, handheld radios will talk line-of-sight up to 2 miles. Anything you get further is "bonus". Dealers cringe everytime we see an advertising claim of 5 miles or more. Here is a good explanation of range: http://www.hitechwireless.com/understanding-radio-range.htm

If you are unable to get your radios to work correctly, since they are new, I would suggest returning them for another set.

Motorola Talkabout T5720


Hello kenyond,

The range that you can expect to see when using two-way radios is very dependent on local conditions. These radios are very line-of-sight dependent. Obstructions like mountains, hills, tall buildings, thick vegetation, and using the radio in a shielded environment such as inside of an automobile can block your line of sight and limit your effective communications range.

That “maximum 5 mile” advertised range is probably only practical in a situation where the user of one of the radios has some significant elevation (such as being on top of a tall hill) and therefore has increased line of sight. When communicating over relatively level ground that is clear of obstructions, you can probably expect a reliable communications range of about a mile.

Best Regards,
Agent Ken
