Try hooking it up to a lighter plug or hook it to direct power . As long as there is no need for electricity does it still do it?

Do you have any other nearby devices that emit radio frequencies like a wireless router or a cell phone? I have had issues with buzzing on some of my speakers when my cellphone was nearby.

My Ranger2950 has no sound??


Have a look here for info about the Ranger 2950. This is an Amateur 10 & 12 meter transceiver that enjoy some popularity due to its ability to be modified to work on the 27Mhz Citizens Band.

Make sure the Mode is set to something other than PA. A few of the first things that come to mind is the Volume, Squelch & RF Gain settings. The Volume is straight forward - choose a setting in the middle to begin. Next, set the squelch. Most radios have the squelch open when set fully counter-clockwise. As you move the squelch to this position, sound should be heard from the speaker if a signal is present. As long as there is an antenna connected, the radio should "hear" noise. If you do not hear anything, leave the Squelch fully CCW and try varying the RF Gain fully in one direction. If you still hear nothing, set the Squelch to the fully clock-wise position. Adjust the RF Gain to the opposite direction. At this point, you should have heard something - even if just static hash. If not, the volume control may be dirty. Disconnect power and rotate the volume control back and forth several times to dislodge any dirt on the volume wiper inside the radio, and try again.

Make sure that the Ext Spk jack does not have a plug inserted as it will defeat the internal speaker. Likewise, if using an external speaker, make sure it works.

Good luck!

How do you get the RX icon to turn off? The unit just has a contant fuzzy buzz.


RX represents "receive" This indication will be present whenever the speaker is producing audio. The "buzz" you're talking about is probably static, and is technically audio from the speaker. To silence the "buzz" adjust the squelch just until the speaker falls silent. The RX indication should be off at this point.

It is important to note that the squelch is designed to keep the speaker silent until a signal is detected. You adjust the squelch based on the level of static at a particular time and at a particular location. The static level may change depending on those variables. If you adjust the squelch well beyond the point that the speaker is silenced, you may not be able to hear transmissions or calls to you unless the caller's transmitter is physically close to you. This is why the squelch should be adjusted only until the static is stopped and the speaker is silenced.

I hope this helps and good luck!

Most likely your antennae wire popped off the radio. Anti-theft usually locks you out after a 3rd time of entering the wrong code. Then you have to leave power off to it for a day and try again.

My radio recieves ok but only whistles when i key the mike is this a major fix?


Do you have talkback installed? It my be too loud and causing feed back. Back the mic gain down if so.

Could also be improper mic wiring. If you use a mic that is wired for a different radio, it could just cause a hum, buzz or squeal.

Another thing that can cause a hum, buzz or squeal is a faulty volume and or squelch knob depending on the radio.

  • Turn down or disable talk back.
  • If you cannot turn off or disable talk back, lower mic gain.
  • Try a different mic that you know is wired for cobra.
  • Play with volume and squelch knobs while TX and see if it stops at all. If it does replace knob.

Carlsbro dsp marlin amp is buzzing loud constantly even without anything plugged in, can anyone help?


Hi,

If it's buzzing even when the volume is down, there must be a problem in the power supply.
Then you have to look if there's a diode or capacitor not correct.

Kind regards,
Gerard

Constant Buzz coming from SX-255r


Power source harmonics. Or its power supply regulation. Check also if input line is touching something.

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.
