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!

Cobra marine band radio will not transmit more than a quarter mile is it blown?


Before changing out the radio try the radio on a ANTENNA RADIO TESTER or try it on a different antenna. Good luck.

18 miles max range but actual it can transmit and


The reason for this is due to various possible conditions. The first being obstacles in the operation range of the unit. IE> hills buildings trees ect. This can greatly reduce the actual distance the unit will work in. The 18mile max is probably a rating that would apply in the best opt. scenario. You would have to be on a flat terrain with no hills or valleys,no trees or buildings for the unit to reach the max distance. In dense areas of trees,buildings or uneven terrian you wont even come close to these distances. Second: any unit RF unit that is held in your hand or close to your body does cause the antenna to detune to various degrees the amount that it does depends on how well the unit has been designed. The more it detunes the less resonated frequence is recieved and amplified making for a weaker signal. In conclusion for the best long range reception be clear of as much surronding interference as possible and as high a possible above any elevated terrian

Hi dstrand, sorry you are having a problem. I will need some more info if you can. Is this radio in a base situation or mobile? Have you had any work don recently? Have you changed anything on the system? (Microphone, antenna, coax, etc)

Haave you checked your swr recently/ If yes, did you use a seperate meter or did you use one built in the radio?

Hope to hear from you soon.

Cobra pr250 2 way radios


Hi,

Pls verify that both radios are:
1. within range of each other;
2. channel selection is identical;
3. CTCSS Privacy Code is identical;
4. Call Tone is identical;
5. Receive icon appears when the other radio's PTT is pressed;
6. Auto Squelch/Max Range is set to receive even weak signals.
Please correct settings if needed.

In some cases, it is the internal speakers that goes bad.

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

Good luck and kind regards.

Long range mode


Hi,

For the Cobra PR4700WX:
The user's manual is available here
To turn on/off the long range mode - (If you are referring to low & high power); Press and hold the Hi•Low/Enter button for two seconds.
Alternately, if you are referring to the Light/Max Range (receive sensitivity), 3 options:
1. To briefly turn off auto squelch - Press the Light/Max Range button for less than five seconds. If you hear two beeps, you have turned the maximum range extender on.
2. To turn maximum range extender on - Press and hold the Light/Max Range button for at least five seconds until you hear
two beeps which indicates the maximum range extender is on.
3. To turn maximum range extender off - Press and release the Light/Max Range button or change channels.
Probable reason that "fishing was all right but for hunting there is to much static" is becasue these radios operate on line of sight principle. Anything that obstructs the linear view would reduce signal strength/range. There is not that much obstruction when fishing compared to that when hunting in the woods or rough uneven terrain.
Please note that when using Channels 1 through 7 and 15 through 22 on high power, the Hi icon will be visible on the display. When using those channels on low power and on Channels 8 through 14, the Low icon will be visible on the display.

For the Cobra PR3500DX:
The user's manual is available here.
The transmission message icon off when not in use - this icon will only display if the radio is receiving something or if your are pressing the PTT button.
The other three the transmission signal is on at all times - indicates that either you are transmitting (unlikely) or the radio is in constant receive mode (most likely). I would venture a guess that the Auto Squelch is switched "OFF" or Maximum Range is switched "ON"

Both the 4700 & 3500 has Power Saver and it is a built-in feature. Your radios have this unique circuit designed that extend battery life. If there are no transmissions for 10 seconds, the radio will automatically switch to Battery Save mode and the Power Saver icon will flash in the display. This will not affect the radio’s ability to receive incoming transmissions.

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

Good luck and kind regards.
