No Auto Squelch on Cobra PR4700WX

I have a pair of these radios and like them a lot. One is stuck with no squelch. The other works fine. I have turned on and off the Auto Squelch/Max Range function but the static is not squelched. Is there an internal adjustment to tweak the level?

Constant static on my walkie talkie


Check the squelch level, either the knob or on the menu. When the squelch is 'open', there will be constant noise. If someone is transmitting nearby, do you hear them clearly? If not there may be a problem with the receiver in the radio.

Squelch won't turn off, won't go into power save mode


Power-save mode means the radio is being turned on and off repeatedly, to save power. The radio turns on, & if it hears any signals (i.e., if squelch circuit determines a station is being received), it turns on the speaker; else it turns off again to save power. So, squelch and power-save modes work hand-in-hand, and your problem is squelch circuit is either set too low, or a station is being received by the receiver. Download/look at the owner's manual and adjust the squelch circuit for a higher setting, and it should go into power-save mode again.
Good luck.

Cobra PR4750WX - how do I adjust squelch?


You are right there is no adjustment. You can however turn the squelch off and this maybe what is happening to you.
To turn the squelch off you press and hold the button that is just below the push-to-talk button for at least 5 seconds.
To turn the squelch back on, you either press (less than 5 sec.) and the same button or change channels.
When talking with a specific party or group, you should use the tone coded squelch (CTCSS) and that will mitigate the noise if you are not already doing that.

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.

No book looking for help


Hi, Looked for a book thru google, but no luck. I did see where they have an automatic squelch. The auto squelch should keep them quiet till someone keys up.
Features, 14 channel, no GMRS, 1/2 watt output, LCD display, autosquelch, rechargeable battery pack. That's about all I can help you with,, Mechanic good luck.

Constant Rx


Hi, It would initially seem that your auto squelch is malfunctioning. With the squelch apparently way down, the RX indicator would automatically appear as if you are receiving something (even if it were just noise). Assuming no other fault except the auto squelch, a possible workaround is to use any of the 38 CTCSS codes both in receive and transmit. With the CTSS activated (TX/RX), even with squelch all the way down or auto off/defective, you will not hear anything except a radio transmission with the correct CTSS code. Again, this will only work of course with just the auto squelch muting problem. Any other problem/fault and this method may not work. Hope this be of some help/idea. Post back how things turn out or should you need further information. Good luck and kind regards.
