I tried to Tims and other versions of coupling, that's why I purchased the longer and tougher radio antenna to begin with. It definitely is better than any other antenna for shortwave except for the steel whip. Anyone who has used a steel whip knows that it has no peers when it comes to shortwave listening in a vehicle, of course that is just my opinion but if there's better I want to know. |

Bill Baka Way back, my old Jaguar Mk 10 had a radio made by PYE that had standard broadcast and short-wave. Or was that the Mk II????? Short-wave reception was spotty, and I never did try a long wire antenna on it. Steve R. I seem to remember an old valve car radio that had some shortwave indicators on the dial. It was one of those common brands (AWA, Kreisler, Pye) but exactly which one escapes me now. It was a long time ago. Not my car, a friends, and we used to go on trips in it. Slow to warm up and heavy on the battery if you used it too long without the engine running. Caught us out once or twice but a roll start got us under way again. I seem to recall that car radio sensitivity on MW broadcast bands was a lot better in the fifties and sixties than it is on modern car radios. During the evenings, I used to be able to pick up stations 1 or 2 thousand kilometres away with ease. Nowadays, I only need to be a couple of hundred kilometres way from my home city and I lose the signal. Maybe the transmission power has been reduced? I know there was a time when the MW spectrum became a bit crowded So that might have been why the front end sensitivity of car radios was decreased. Well, the MW spectrum is getting less crowded now. Krypsis- Hide quoted text - - Show quoted text - Yeah, I have gone "old school" for fifteen years when it comes to AM car radio. I don't really listen to music so I make sure to go to the junk yard and find me an old (just AM) radio that I install myself. I am presently using an old Delco radio that is "extremely" selective, I can barely turn the dial without hearing something. I had all (in my *fun* car) the receivers/scanners and CB mounted to 1/2" steel plates that I welded to the front and rear of the car. GROUND - GROUND - GROUND - many think it's only important for transmitting but it's also smart on the receiving end. |

I have a bunch of old tube type AM and a few AM/FM car radios.
My dad used to own a blue 1955 Ford Station Wagon car.The AM radio in that car was very good for AM DXing. cuhulin |

That actually makes good sense since I don't want to listen while driving anyway. The fading would drive me up the wall. I know the deal on car antenna lengths and the antennas on most cars would probably tune to 144 MHz or somewhere way up there. Figuring out how to fake a good earth ground might be a challenge unless the mass of the car would make it a good ground. All for now. Bill Baka- Hide quoted text - - Show quoted text - Just so you know Bill, you *can* listen and drive without fading if you're listening to a powerhouse. I listened to China's show from the beginning on my way to Columbus and some hams for the rest of my hour and twenty minute drive from Cincinnati. Like I said earlier, the best way to ground IMO your receiver or transceiver is too run to the hardware store or your junk box and pickup a quarter to half inch piece of metal/steel and drill the appropriate size hole and weld it to the frame of your car. If you don't know how to weld or don't have a arc welder....go to any body shop. Either they'll do it for free or throw them a twenty spot and it's done. Ground - ground and more ground is my motto. Good luck and let us know what you do. |
