using a car radio inside my house
I live in a bad FM reception area and I've noticed that my Blaupundt Tucson
(in my car) gets much better reception than my portable Tecsun DSP radio. I'd like to hook up a Tucson inside my house and have to figure out a power supply/converter for it. Being a tuner, it needs an amplifier and I have some Blaupundt amplifiers that go with the various Tucsons I have. But I don't know exactly what type/brand of power supply I would need for running this setup of my house current. Can someone give me some pointers towards figuring this out. Thanks, John |

Thanks, John Supplies can run over a hundred dollars. Look up, using a computer power supply 12 volts. Greg |

Radio shack and other places probably have power supplies for 12V devices, often with a cigarette lighter jack. You could probably get away using a 12 V "wall-wart" as long as it has sufficient amperage output. |

Bench supply http://www.mcmelectronics.com/product/72-8142 Wall supply http://www.jameco.com/webapp/wcs/sto...001_2151208_-1 Notice it's almost impossible to find a wall supply of nominal 13.8 volts. It all depends on your loudness levels. Loud means high peak amps. Depending on the supply, some computer supplies deliver 10 amps or more at 12 volts. You can find these for free. Greg |

using a car radio inside my house
I like the idea of using a computer power supply, and I have several used
ones around. And thinking about the 12v limitation, I've run my car radio many times with the voltage around 12-12.5v, and the car itself (VW Vanagon) will start up as long as it's computer gets about 10.5 to 11v. So the radio must be designed to function with less than 12v. Since this car has been parked for two years, and the battery goes down regularly, I'll check and make sure the radio and amp will work at and below 12v. Thanks for the ideas...

Greg Just check up on how to load 5 volt section if needed. Greg |

Are you referring to the +5v output from the computer power supply? Would
that be used as a trigger voltage between the car radio and it's amplifier? "gregz" wrote in message ...

The 5 volt usually needs a small load for the voltages to settle. Greg |

Car regulators produce a varying voltage. Power anywhere in the 12-15 volt range should work fine. Lower voltage would likely just produce more distortion at higher volume. |

If I'm understanding you correctly, I need a load on the +5v of the computer
supply or the +12v will be variable. Can you suggest, to a non-electronic person, what (and how) I could use for a small load. "gregz" wrote in message . ...

Can you suggest, to a non-electronic person, what (and how) I could use for a small load. Add 1-10 ohm resistor across 5 volt to ground. Will get warm. Pins should be on Internet as well as everything you need to know. Here is a resistor set from the shack. http://www.radioshack.com/product/in...ductId=2062291 Greg |
