Car Radio My son is fitting a new car radio in a Vauxhall Corsa. The pre-set stations disappear when the engine is turned off. I take it this is an electrical fault, any idea where he should start looking please ?

Yes, my best bet is that there is no constant power going to the radio. Usually car stereos have 2 power wires. Generically, they are yellow and red on most major car stereos. The yellow wire needs to be powered at all times and the red wire needs to turn on when the car turns on. It is possible that you have them switched around. It would still work if you have them switched just wouldn't hold any memory. If they are correct I would search for a blown fuse. Make sure to check EVERY fuse. If you need further help, let me know the make, model and year of the car you are installing into and the model number of the stereo and I can tell you exactly what you need to do. Good luck.

I have a sony wx gt90bt car stereo and I can only get the local station on am, the fm works just find.

I am not sure what type of car you have, but if it is reasonably modern, you will have what is called and "Active Antenna". This needs power and is usually powered from the car radio. I am sure that when the new radio was installed, this connection was missed. FM will work fine around town, but get a few miles outside, and you won't have anything. AM will be very noise or non-existant, as you have found out.

I had the same broublem with a used car that I had purchased. Once I connected the power to the antenna up, I had AM stations coming in from 200 miles away, and FM for 75 miles or so.

Diagram setting up cb radio in house

That depends on your power source and what type of antennae you're using. Can you tell us if your antennae is a mobile antennae or a home/base station antennae? What is your power source, a car battery or a 120 volt AC to 12 volt DC converter? More info is good.

My vo Volvo s40 radio is not working Radio want code which code is that

You will need to call a Volvo dealership and they will ask for the Vehicle Identification Number and they will look it up for you. If you bought the car new, you should have gotten 2 cards with a 4 digit number- that is your radio code- it is unique to your radio and should be recorded somewhere if you disconnect the battery or the radio fuse.

It is simply entered via the station preset buttons.

If you make a mistake entering the code, just pull the fuse for the radio for about 3 minutes and try again.

The code is an antitheft feature.

Hi. My son just bought a new (in-box) Cobra 19 DX II and wants to use it as a base station. Can you tell me what I'd need to get to use this inside the house (power source)? Thank you

tripp lite, pyramid, and others make powersupplys for home use. for that radio. 5 amps should be enough.. but you may find a better deal on a 10,12- even 20 amp go with it.. if you need help call us would be glad to assist.

CB Base Station picking up electrical interference

i dont know what AC DC adator your using. you should look into a 12V power supply. or plugging that into a RF canceling power strip, like a monster power strip. TV's that are on or other appliances may cause high noise levels on the CB, make sure your coax is good, your antennas good, and all jumpers are good. its hard to tell with out looking at it, but do a quick once over of the system.... you are using a base antenna right? if not you need to create radials for a mobile you plan on using for a base.

Make sure the connectors on the coax are all on right, this causes problems a lot of the time. sometimes even brand new coax have bad connectors installed.

Wx stations disappeared

They did not put all the plugs back in from the weather board. Part of what has to be fiddled with is underneath the weather board.

Open the bottom cover where the speaker is, on the right side you will see a board separate from the main board. Look for any plugs unplugged. Its probably one that got over looked.

If there are no plugs out, who ever you took it too may have turned something they should not have. most likely its a plug. Its probably the plug that runs the audio into the radio from the weather board. its working, the audio just isn't getting to the rest of the radio.

there are about 3 or 4 plugs from the weather board to the main board of the radio.
