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.

SOURCE: AXU4100 Manual or help

Hi,

On a Motorola AXU Series (including the 4100):
1. To unlock, press the “D” button for about a second or until the circle is gone. The circle with the line thru is the keyboard lock indicator;
2. To change channel, you need to press either the arrow left or right in Normal Mode;
3. To change PL (assigned to a channel), don’t think this can be done by the user
4. To change Ch. 1 from 464.500 MHz (PL-67.0) to 463.525 (PL-136.5), don’t think this can also be done by the user.

Even the built-in Programming Mode Parameters do not have this option to change assigned frequencies and PLs. An external programming software using a PC may or may not allow this.

These radios came pre-loaded with its channels assigned with specific frequencies/PLs. As used in a Motorola AXU411, they are:

Channel Frequency PL
1 464.500 67.0
2 464.500 77.0
3 464.500 88.5
4 464.500 179.9
5 464.500 None
6 464.550 67.0
7 464.550 82.5
8 464.550 94.8
9 464.550 179.9
10 464.550 None

Hope this be of help/idea. Pls post back how things turned out or should you need additional information.

Good luck and kind regards.

SOURCE: change scanning feature for different channels

When having the radio programmed indicate to the programmer which channels you would like to have in a specific scan group. They an at that time set up a particular group for you.

SOURCE: Motorola T5728 walkie talkie freq mismatch

Unfortunately the T5728 is not compatible with the US FRS (family radio service) frequencies. The T5728 operates between 409-410MHz. The FRS radios operate between 460-470 MHz. FRS frequencies are license-free frequencies for use in the US, as regulated by the FCC. Other countries have differing rules and thus their frequencies assigned to family usage differ.

Motorola MT352R can transmit but cannot hear


Check your Code setting. Both the frequency and the code must be identical for the units to communicate. Shut off any special features and keep the radios at a simple setting until you get communications back.

Typically this would indicate a battery problem. Try swapping batteries with a known good unit. If the radio still shuts off when the PTT is pressed you have a radio problem. If it works fine, then you know your battery, despite showing fully charged, is bad.

I have a Motorola Axu4100 , I want to change the frequence that I currently have on this radio to a Motorola CP-200...just wondeing if these two radio can work together....


Hi
Motorola CP-200 have frequency range 
VHF: 136–162, 146–174MHz;
UHF: 403–440, 438–470, 465–495MHz depending on the model
Motorola AXU4100 have frequency range 435 - 480 Mhz
The first model has a wider frequency range so it is best to include transmitter Motorola Axu4100 to transfer and try to receive signal to Motorola CP-200
