Question about Connex 4600 Base CB Radio

2 Answers

Background noise I have an unusual amount of background noise. I can't seem to get rid of it without setting my squelch so high that I can't receive anyone more than 5 feet from me or turnning my rf gain down to the same point. I realize that some noise is normal but this gets so bad I can't hear anyone talking, even when they are real close to me.

    at a stop or slow speeds little background noise. speed up to driving speed background noise increases to where i can't hear anybody. after driving a mile or two background noise starts to break up then goes to normal. i have checked all connections on ant. coax &power cables all clean&tight.

Buy an inline filter, the alternator on your vehicle interferes with the sound. that is all you need. you can find them at any good cb shop.

I'm not an expert but I am a daily operator. First check your ground connection, just because the radio turns on doesn't mean the ground is good enough. If this unit is mobile there are several things you can do to reduce the noise. First you need to find out if the noise is coming in thruogh the antena or the power supply; turn on your radio and vehicle, unhook the antena. If the noise goes away or is reduced you know that it is RF noise. this is interference from some outside source, powerlines, TV, just about any thing that uses electricity or electronics can cause noise. relocating the antena may help. Check you antena connections. Check your SWR. This is only a few of the things you can check.

Yaesu ft-857 squelch problem


Your RF gain control needs to be turned all the way up to be able to receive signals and if you are on one of the HF bands like 40 meters or any HF band the squelch control needs to be all the way off! You do not use squelch on HF! When on VHF or UHF then you would rotate the squelch control just to the point that the background noise stops and go no further. Higher squelch settings will only block weak signals and your radio will be deaf! Squelch control rotated just to the point the background noise stops! NO SQUELCH ON HF. Turn the squelch all the way off on HF!

What is a voic box on a cobra 29 ltd? What is a good antt combo four a 29 ltd?


Cobra's LTD 29 model Citizen's Band radio features the full 40 channels allowed and a heavy-duty microphone. The radio provides 4 watts of AM radio frequency output with a switchable automatic noise limiter and noise blanker. Other features include Cobra's Delta-Tune function. Making a Cobra LTD 29 hear and receive better involves making changes to the radio's settings, including the settings specific to this brand.
M/F Turn the switch labeled "NB/ANL, ANL, OFF" to the "ANL" position and try the transmission again if noise is affecting reception. "ANL" is an automatic noise limiter function and reduces noise caused by the vehicle's electrical systems and electronics.

M/F Switch to "NB/ANL" to activate the noise blanker, which may also reduce noise if you continue to have problems. It's an RF noise filtration function and will help with ignition noise.

M/F Adjust the "RF Gain" knob by turning it clockwise to increase gain in weak signal areas if you have problems hearing radio traffic.

M/F Set the "Delta-Tune" function to capture a more listenable signal and get rid of adjacent channel noise. Rotate the knob labeled "Deltatune" to the center position for best tuning. Try micro-adjustments to the left or right as well.

M/F Turn the volume up if you still can't hear and as with any CB radio, adjust the squelch if the radio is noisy when there's no traffic. Turn the knob labeled "Squelch" all the way to the left to receive all signals, including noise and turn the control clockwise until the background noise stops. You will be able to hear the strongest transmissions without having to listen to weak signals and noise.

How do i adjust the squelch?


Turn the squelch control clockwise just enough to cut the background noise, this should work well for local communication.

How can i hear what they are saying without that awful loud sound when they arent saying anything. cause when i turn the volume down i cant hear what they are saying


Turn up your SQUELCH button when no one is talking until the static noise just goes away.

Now your set will remain quiet until someone talks.

If you set the squelch too high it will also cut out the people talking, so always try to have it set just slightly above the background static level.

Good luck.

I feel that the 'normal' background hiss is a problem that I would like to minimize with the sennheiser IEM 300. I'm currently using the IE 4 ear phones. Would a different/better earset with maybe a...


No, that will not help. The his is a function of the receiver NOT receiving a signal from the transmitter as they apparently do NOT have a "squelch" circuit to mute the receiver noise when no signal is being received. The noise level when no signal is received is pretty high and apparently the volume control is not enough to reduce the hiss.

To solve this, LEAVE the transmitter ON and make yourself a switch at the receiver. DO this using one of those little in line lamp switches that fit on zip cord. Make one on a short length of zip cor with mating connectors to fit the received jack and the headphone plug. Don't worry about unshielded wire as the impedance is very low. Then you use this switch to mute the headphones when you want to. There are other switch types you can use, I am just suggesting what might be readily available to you.

Sennheiser SHOULD have include a mute switch on their unit as turning the power off on the receiver would be a pain. They could have used a volume control with switch to kill the audio line out... simple solution... oversight on their part.

I have to keep my rf=gain turned all the way down or I get terrible feedback. How do fix it?


The RF limits the signal strength you radio receives. After setting the RF to limit excessive signals, then set your squelch up until the noise is gone. There are some areas which have high RF background noise so adjustments are made often while driving around. Use the ANL (automatic noise limiter) and other features also to control the noise.

Secondary audio drowns out primary audio


if you are using a surround sound receiver for your audio, you need to change the surround mode. i like mine set up for dolby pro logic. there are many different settings on the new recievers so experiment until you find one that you like.
if your sound comes only through the tv, use the audio menu and set it to stereo, although with some brands "surround" will get rid of this problem

Voices drowned out by background noise.


Not a suggestion, but I hope there is a solution.
Recently bought an LG HDTV that has a setting that should increase the voice over the background. If it does, I can't notice the difference. I guess they can probably measure it electronic.
I've had your same complaint for years, without a good solution. Best so far is to use headphones.
I have no idea why film people add all the extra noise. Most of it is not even real.

Recieving problems


turn the RF gain all the way up and leave it there. Also turn the squelch down until you hear white noise, then turn it up just until it goes away.

RF gain is how sensitive your receive is. The higher it is, the more range you have. There really is no need to turn it down ever, unless you are trying to not hear some one out in the distance. Normal operation, RF gain should be all the way up.

Now squelch is used to quiet non signal noise. Like white noise or interference noise, Or other radios with a really weak signal that you can't hear completely any way.

You just want it so it just quiets the fuzz noise. Depending on background interference and the amount of radio traffic, the may have to be adjusted to silence the noise you don't want to hear. When a strong audio signal is received, it will break the squelch, the higher the squelch is set, the stronger the signal needs to be to break it, otherwise it will silence it.
