Lots of white noise on radio reception - Dewalt DC011 AM/FM Radio

Are you using the noise blanker? Are you also finding noise on regular AM radio in vehicle? How good is the connection on the coax?

How good is the antenna ground to chassis? How good is the antenna?

If you address the various sources of general RF hash that would also aflict the AM reception in your vehicle, that would be the first thing to address. It would probably be a good idea to use some contact cleaner or LPS1 and spray down the switches and controls. I know on one of my own that the dirty contacts are enough to kill off reception.

If these things do not improve it, and you do not mind going into the radio- in the reciever stages are a number of 1N60 diodes, and they have a nasty habit of becoming leaky and noisy. Replacing them should help quite a lot if nothing up to this point has.

may be you have a ground wire loose

There is interferance in th esytem that is causing this effect. If the noise is coming while in motion then the noise is induced from the electrics of the vehicle.
Check or add a 0.47mfd/100Volt capacitor which is a clip type to the power into the set. If not use a DC/DC isolator or even a inductance coil with a capacitor , one you can salvage from an old set.
Make sure the antennae is good and the local reception is strong.If not the static might dominate.

sounds like you need a capacitor, this is a common problem with stereo's, especially when an amplifier is installed, and if you listen to AM radio a lot, it may be a good investment. They're pretty inexpensive, if I recall, generally a cheap one is under $30 dollars!

Could be a lot of background noise.
Could be no one near you.
Could be RF GAIN down.

standing wave does not effect receive, it only effects transmit. If you are sitting still some where, you could be in a hole. Depending on where you live there could be a lot of background noise, RF interference. For instance Staten Island is known as "Static Island" because of all the RF interference.

Where you are at, it may be a fact of life.

Hello,

If the "static" you are getting is a high pitched whine and the noise volume increases and decreases with changes in engine speed, you probably have alternator induced radio noise.

Many times such noises are caused by poor ground connections that have begun to corrode over time. First try removing or loosening the screw or bolt which grounds the radio to the vehicle frame. Using a fine wire brush or a piece of steel wool, clean off both the terminal and the location on the vehicle where it was attached. Then reattach the ground. While you are behind the dash, make sure that the antenna connection is fully seated. Pull it out and put it back in again to make sure.

If these steps do not solve the problem, you may need to install noise supression devices. The are available at many retail locations like Radio Shack and some auto parts stores, as well as numerous online stores such as: http://www.crutchfield.com and http://www.sonicelectronix.com.

Go to a radio shark or to a phone store and tell them u want the Reception Booster that goes inside ur battery pack and this should improve ur Signal. :)

Turn on the radio and turn the AM/SW BAND switch to the AM position. MW appears in the display. Use the outer ‘fast’ tuning knob to find stations, fine tuning with the inner ‘slow’ knob
when needed.

• If there is interference from adjacent stations, place the BAND WIDTH control in the NARROW position. If there is no interference, leave it in the WIDE position.

• If there is excess background noise, turn on
the SW LPF switch, which may minimize the noise.

• If a station is so strong that audio distortion occurs, reduce the gain level with the AM/SW RF GAIN control knob by turning it counterclockwise.

• The telescopic antenna does not have to be extended for AM reception. The radio has an internal, directional, ferrite-bar antenna for AM reception.

• To optimize AM reception, swivel the radio until maximum signal strength is achieved.

All of that being said: It's very tough nowadays to receive AM in this 2008 electronic world. If your able install a longwire SW antenna outside, and have access to a good earth ground, you can boost the AM signals and beat the noise being generated all around you.

Don't take your radio to work. Get your work done , then go home and listen to it. You will get better reception in a res. area.

I have seen a lot of those radios that has a "factory problem" to determ this fist check that: Both radios must to have same channel and same Code. Basically has to have the same numbers on display. Check if one of them has the Quiet Tone. Work in any area?--- if you have a Pair of radios they must to work between each other, mostly of this radios works in FRS frequencies as a Talk About from Motorola This radios can present some problems with frequency error, but if you have no the necesary equipment you could not to ajust it. I hope this tips can hel you Ernesto Garcia
