    I even added "New" fresh AAA batteries and it still indicates a low battery condition.

Hi,

There could be three (3) reasons why the display shows the battery icon at the top left side of the LCD display:
1. weak/undercharge/discharge batteries;
2. dirty/corroded/loose battery contacts/terminals; and/or
3. internal fault with the electronic sensing for battery level/state.

Corrective measures would require:
a. replace/recharge batteries. The rechargeable batteries need at least 12 hours of charging time;
b. clean, scrape, tighten (need to bend a little more towards the battery terminals) the spring/contacts of the battery holder;
c. (on the internal fault) your best bet might be to seek the services of a professional electronic technician since this would need familiarity with electronic components, their circuitry and diagnosis, perhaps a bit of soldering and the use of a DVM.

On the other hand, if the "low" is the "L" icon at the bottom right side of the display, this would indicate that the radio's transmit power setting (H/L - high/low). Transmit power level can only be changed in Channels 1-7 & 15-22. The radio will also auto change to lo power when batteries are weak.To switch to high power, press on the Menu button thrice or till "Pr" icon shows, press on the up/down to select H or L. To save & exit, momentary press the PTT.

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

Good luck and kind regards.

How long should you charge the batteries on your Cobra cxt235 when you first get it?


Hi,

usually overnight is the best with the radio turned off.

Always charge your batteries with the radio turned off, else you'll burn out your batteries before their time was due for replacement.
I hope I have answered your query for you.

Best regards,
Peter

How many watts do midland walkie talkie xt20 have?


These are FRS/GMRS (Family Radio Service/ General Mobile Radio Service) radios. The legal power limit for FRS is 500 milliwatts - or 1/2 watt. GMRS on the other hand is limited to a much higher 50 watt level. The wattage you transmit determines if you need to have a GMRS license. Most GMRS radios are in the .5- 5 watt range however.

The likelihood of your XT20 being a 1/2 watt out on both FRS & GMRS is very good. For Midland (or anyone else for that matter) to produce a radio with a 1 watt output that can run on just 3 "AAA" batteries would be quite the feat! If Midland did do this, the radio's battery life would extremely short. To balance the needs of light weight and battery life, output power needs to be reduced.

Claims of 20 miles is crazy. If you had these radios on mountain tops 20 miles apart - with a clear line of sight between them - MAYBE - you could hear one on the other. This would need to be done under only the most ideal conditions. The actual distance you can expect to get out of a pair of any brand FRS radios in "real world" conditions (line of sight blocked by trees and buildings) is about a mile.

An FRS/GMRS radio limited to 1/2 watt output when used on a GMRS frequency that is close enough to access a GMRS repeater system could easily cover 20+ miles. The key here is having a license and access to the repeater. Repeater owners take a dim view of unlicensed users access their repeater.

Channels 1 thru 7 are FRS and GMRS. That is, if transmitting .5 watts, you can use it as FRS. If transmitting more than .5 watts, you will need a valid GMRS license.

Channels 8 - 14 are expressly for FRS. Only .5 watts transmit power is permitted.

Channels 15 - 22 are expressly for GMRS at any transmit power up to 50 watts. Even if transmitting .5 watts, you MUST have a valid GMRS license on these frequencies.

I know - more infor than you wanted and no vclear cut number for wattage - but there's no info on these radios on Midland's site or anywhere else that I could find. Good luck!

Can two different style motorola 2 way radios be changed to same frequency


Hi Kate,

The short answer to your question is: no, or "not readily". Here's why:

The Motorola 4900 radio operates in the FRS (family radio service) and GMRS (general mobile radio service) in the UHF band. This radio will work with any other FRS / GMRS band radios (no reprogramming of transmit and or receive frequencies is possible for these radios). The trick is that the numbering of the channels may differ from brand to brand ie: Ch1 on your Motorola may not necessarily be Ch1 on a Midland radio or other brand. A complete list of the frequencies and channel assignments for FRS /GMRS can be found on Pg. 17 of the manual. It is important to note that without a valid GMRS license, you are prohibited from transmitting on the GMRS only channels (Ch 15 through Ch 22). The combination GMRS/FRS channels (Ch1 through Ch7) and the FRS only channels (Ch8 through Ch14) are for individuals and family members that do not have valid GMRS licenses. If this is you, you should limit your transmissions to Ch1 through Ch14 only, as FRS does not require a license in the US. Unlicensed use of GMRS only Ch15 through Ch22 can result in fines and imprisonment if caught by the FCC.

Further complicating the issue are the so called "privacy tones". This is simply a very low or "sub-audible" frequency that is sent whenever transmitting. Motorola calls these "Interference Eliminator Codes". When another radio receiver is set to listen for a particular privacy tone, it stays silent until a transmission with the exact same privacy tone is detected. Again, these tones are listed in no particular order, but are generally listed as 1, 2, 3, etc. or a, b, c, etc. instead of the actual frequency in hertz. You can selectively set your radio to transmit & receive one of the 38 codes or, set the code to "0" to communicate with radio that do not offer these privacy codes - or does not use the same frequencies for these codes. You can read more on Motorola's codes on Pg. 19 of the manual.

The Motorola CP200 radio on the other hand is a commercial radio, and requires computer programming with Motorola software. The CP200 is offered as both Low & High sub-banded VHF and Low, Mid & High sub-banded UHF radios. You would need to have a CP200 that is designed to accept the Mid UHF band (438Mhz - 470Mhz) frequencies in order to program the 462Mhz & 467Mhz FRS / GMRS frequencies into it. The final obstacle would be what is called "FCC Type Acceptance". The CP200 is probably NOT Type Accepted for transmitting FRS/GMRS frequencies, and as such the Motorola dealer doing the programing might balk at putting them in. You can read a spec sheet on the CP200 here.

I hope this helps & good luck!

My cobra walkie talkie doesn't work after 2 miles


You didn't include the model number of the radios, but I suspect you're referring to Family Radio Service (FRS) / General Mobile Radio Service (GMRS) two way hand held radios. The FRS /GMRS types are limited to just 1/2 watt. Base GMRS type radios are limited to 5 watts. FRS is limited to Ch 1 - 14. Ch 15 - 22 are GMRS only, and require an FCC license to transmit. You can read more about FRS on Wikipedia.

Many FRS / GMRS two way radios claim incredible distances on the packaging. I've seen some that claim 15+ miles. Given the low power (.5 watt) that they are limited to transmitting, claims such as those would be under the most optimal of conditions. I can assure you that you or I would never encounter those conditions unless we were in some sort of radio laboratory / testing space designed to obtain these crazy distances. In other words, even in optimum "real world" conditions; these radio should only be expected to work when separated up to only several "unobstructed line of sight" miles (such as across open water of a lake, along a beach, etc. The range of these same radios will be reduced significantly when operated indoors, outside between buildings, where blocked by rocks, trees, metal, etc. The only reason you may have reduced range could be due to a power level selector switch that has been set to reduce the output power of the radio. Other than that, I think you'll find a couple of miles is about all you're gong to get.

Good luck!

How to set low power in midland LXT300


  • The Hi and Low power are built into the radio and is dependent on the frequency/ channel you are on. Hi power is 1 Watt and Low power is .5 Watt. The radio is GMRS and FRS. The FRS are low power and the GMRS are Hi power.
  • Channels 1-14 are FRS frequencies and Low power.
  • Channels 15-22 are High power and are GMRS frequencies.
  • FRS = Family Radio Service.
  • GMRS = General Mobile Radio Service.

  • If you have any comments please feel free to leave them here.
  • Hope this helps and thank you for using FixYa.

Midland GXT 950 two way. TX problem


I am sure the OP isn't likely monitoring this, but just in case anyone else needs it... It's a power problem. Try charging the batteries, even though they look like they're fully charged -- or replace with 4@AA batteries.

This only seems to happen on the GMRS channels -- not the FRS ones. The radios come default to transmit at high power (the full 5 watts) on the GMRS channels, but only 0.5 watts on FRS. If you go to settings and change the power on that particular channel you're trying to medium or low, you'd likely find it works with the charge you had problems with.

Recharging or changing to 4@AA batts should get you back up to continuous TX on those high-powered channels.

Channels


All gmrs radios also have frs frequencies in them. The frequencies are staggered.....1 frs....1 gmrs....1 frs....gmrs etc etc.
The only difference between frs and gmrs is power.... you are allowed to use more power on gmrs freq. So thats why they have more range. But the frequencies are right beside each other.

I would be surprised if your friends radio did not have frs channels in it also.
They should be able to communicate... most likly not on every channel but there should be some that the 2 of you share.
