Hi all,
Just got a new 2006 Forrester and want to get my 2M/440 rig mounted along with a mag mount antenna. Someone pointed me to the "rig of the month" web site, but that site appears dead.. Anyone have any web sites that I can look at for information on setting up my radio in my car ? |

Looks like K2BJ pulled the plug on the Mobile pages. Twas nice site too. |

Not to much to study...Find a good place for the radio. Mount it. Throw the antenna on the car, and run the coax through the best opening you can find. The only real important thing to consider is the power source. Don't !!! use cig lighter plugs, etc. Run fairly thick wire directly to the battery, and fuse both the + and - wires. If you do that, you may have to find a plug or hole in the firewall. Most have a rubber plug of some type. If not, you might have to drill a hole. But at least you won't have problems with the rig from big voltage drops due to too thin a wire, or crusty corroded cig lighter connections/socket. MK |

I have a question, though. If you're running, say 10 to 15 watts to a automatic screwdriver HF antenna, can you get by with cig lighter connection? My GMC pickup has two auxiliary connections in addition to the cigarette lighter. My IC-706 runs 100W SSB just fine off of one of those aux connections. But pickups may have bigger wires than cars. -- 73, Cecil http://www.qsl.net/w5dxp |

![]() Large wires, Anderson plugs are good ideas. I have a question, though. If you're running, say 10 to 15 watts to a automatic screwdriver HF antenna, can you get by with cig lighter connection? Thanks, John Many years ago, I used a 35 watt transceiver on a cigarette lighter plug. Someone told me I was making a mistake. We measured the output of the rig, connected it direct and measured it again. The output of the rig was a few watts lower on the plug as opposed to direct wiring. It wasn't significant enough to be detected on the air, but it proved the inefficiency of using the cigarette lighter for a source of power. I now use #8 wire directly to the battery for all my mobile amateur radio wiring. I never tried to determine if it was the plug itself, or the wiring that caused the power drop, but I found a website that allows you to calculate the voltage drop of wire given the length, wire size and current. -- 73 for now Buck N4PGW |

Unsoldered metal to metal connections, especially crimp type, are especially problematic. Ed K7AAT |

(#8 was available, flexible, and relatively inexpensive for the length I needed, #00 was too stiff and large to manipulate in my car. ![]() -- 73 for now Buck N4PGW |

The fuses actually have a good bit of voltage drop across them.
