Question about Motorola EM1000R Two Way Radio

1 Answer

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 trying to re-configure them. I have them both set on the same 3 privacy codes but they do not communicate. I changed the codes and they still won't work. I

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 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.

Best regards.

I bought walkie talkies with 56 km radius and yet we are lucky to reach each other after approx. 1 mile,any idea why we don't get the range


You do not mention the particular model of Motorola, so this answer will be generic in nature. Some Motorola TalkAbout radios have been factory programmed with a few GMRS repeater frequencies. These channels require the use of a repeater tower, which will 'repeat' what you say over a greater distance. It is possible you have this type of radio. Check your user guide, and then set your radio to the appropriate channel for the repeater in your area.

Radio-to-radio without the use of a repeater you can expect up to 2 miles line-of-sight out of most handheld radios. This distance is reduced by obstacles such as buildings, trees, etc. inbetween the radios. It can also be reduced if you do not hold the antenna of the radio perpendicular to the ground.

Best regards.

What channel should i set my motorolla walkie talkie to get the best distance? It seem not to wok beyond 1/4 mile on channel 3.


You didn't mention a model number, so I don't know if your radio is an FRS or FRS/GMRS model. GMRS channels have more power output than FRS does, but GMRS also requires a license for operation. Other than that, the frequencies are so close together that there is no distance advantage gained by changing channels. The manufacturer's distance claims on these radios are pure advertising gimmicks - the radios are line-of-sight only, so if there's anything between the transmitter and receiver, the signal will not get through.

HOW FAR IS THE DISTANCE THAT YOU CAN HEAR ON THE MOTOROLA TR50? I LOST MY OLD MANUAL


Typically handheld radios will talk line-of-sight up to 2 miles. Obstacles you put between the two radios can absorb part of the range. Talking from inside to outside of a building you may only get 1/4 to 1/2 mile. Height and placement of the antenna determines range, so the higher you are the further you will talk. If you were on a mountain top and talking to the valley below, you could talk as far as you could see, which might be significantly more than the 2 miles you would get in normal terrain. (I think the box advertises up to 5 miles, but this would be under ideal conditions, and is not realistic.)

Tranmitting distance


Generally speaking a 2-way radio will talk as far as it can see. Height and placement of antenna determines range. So if you were talking from a Mountain to a valley you could talk a great distance. However, in the real world there are obstacles, such as trees, houses, varied terrain. You generally would expect a radio to talk line-of-sight up to two miles. Or 1/4 to 1/2 mile if talking from inside a building to outside. The quote of 5 miles in literature is referencing ideal conditions. (Much like when the new car you are looking at quotes the MPG.)

Uniden GMR-1035 2-way radion, with advertised 10 mile range


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.
