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. Sounds like my younger days, dead battery just means push with friends and jump in to pop the clutch and get going. I miss sticks. 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. Me too. In the sixties I used to drive out to the middle of nowhere and park and listen. I could DX AM better that way than at home. 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 Thankfully. I want to start DX'ing for QSL cards again if they still give them out. Cheers, Bill Baka |

If you are a bit creative, you can mount the rig in the trunk and stick a small control panel in the passenger compartment. http://rffun.com/catalog/hamhf/0703.html http://rffun.com/catalog/hamhf/1817.html Plus there were many that are no longer made that would do well, if you can get them over there, or shipped to you. Geoff. I looked and like the radios but I am only looking for a receiver and don't want to spend a ton of money. Also, any decent mobile should have a noise blanker, not just a limiter. I did like the built in antenna tuner but it seems a transmitter would be needed to optimize things. Thanks, Bill Baka |

Bill Baka I have a Becker 2340 I used in my 308 for years. That was the last aftermarket radio I saw with SW. I've heard tell of some Sony's, but not being interested in anything from Sony, I never pursued them. The Becker offered excellent SW performance on the car's antenna. A little ignition noise in deep fades, but not enough to complain about. The injectors on 18 wheelers were more of a problem than ignition noise. It has 40 or so memories. And exceptional audio. As for driving out into the weeds...we had a member of this group, living in Colorado, who used to drive out into Wyoming and about two miles outside of Jackson Hole would hook his SW-2 up to the guard rail and use that as a makeshift pseudo Beverage. With dramatic results. But attaching anything to your car radio antenna will not get you where you want to go. A car antenna does not really operate as an antenna. It's too short for medium wave. It operates more like a capacitive element, and is trimmed at the input to optimize performance. Attach a wire to the car antenna, and you'll change it's capacitive value, and throw your input out of balance. You're also likely to change that whip into something that behaves more like a real antenna and seriously overload your front end. On some models this can be disastrous. A better option would be to see if you can find an in-dash on the used market, or take something like an SW-8 with you, mount it underdash and enjoy it as a real shortwave receiver with a separate antenna system. 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 |

I did like the built in antenna tuner but it seems a transmitter would be needed to optimize things. Thanks, Those were just examples. There are many old rigs, Icom's 706 has gone through 3 or 4 generations, the low power version (703) has gone through 2 or 3, Alinco and Kenwood have also made similar rigs, Yaseu has made 2 versions of the 817 and so on. While the new ones are expensive, some of the older ones may be available a lot cheaper. Depending upon which one you get, you can get various filter options or DSP. For example, there were two Kenwood TS-50s HF rigs which sold on eBay for less than $500 in the last week. While I am not a fan of eBay, that should be a good guage of the price. An original (no DSP) IC-706 sold for around the same price. It adds VHF coverage and possibly can be used as a scanner. The latest version (mark IIG) includes VHF and UHF, DSP and receives from .03-199 and 400-470 MHz. The ICOM and Kenwood are two piece units, the front panel comes off and can be mounted in the passenger compartment, while the transmitter is mounted in the trunk. The Yaseu is one single unit.

Once it is stuck firmly just back the car up until the whole spool is used up and connect the car antenna to it. Anybody tried it or anything like it? Bill Baka There is always XM radio. BBC world service all the time, and many other shortwave stations on a rotating basis. The point was I want to do my own searching and not listen to some lame satellite station. I will *never* buy a car that requires me to pay a satellite station $10 every month. If you are going to do any SWL with a fixed antenna, there is really no need to mount it in the car. I have a Welbrook ALA100 that I have used in the field many times with home brew wire loops. http://www.lazygranch.com/images/radio/loop1.jpg Interesting looking setup, could be used as a direction finder too. I have a marine RDF but it uses a pre-mounted loop-stick in the rotating antenna. Too bad it cuts off at just over the old 2805 frequencies. Thanks for the picture. Bill Baka I've done NDB DFing with the loop. It works great for that purpose. However, it is better to use a smaller loop. I find 2ft on a side works best for DFing. I have a setup with a holder for a compass. That loop uses copper pipe. Regarding shortwave radios in the car, the specs on the Sony are pretty poor. I'm not sure it was targeted for the US market, where there is little good shortwave to hear, other than VOA. I've seen people mount those DC to daylight radios in the car under the dash for shortwave. |

Bill Baka "BB", Grounds at a 'Remote' DXing Spot -wrt- Making the Ground 'Connection' During a Mobile DXing Field Trip. You drive up to a Rest-Stop, Camp Ground and Attach a Ground Clamp to some piece of Metal {Pipe} coming out of the Ground. This is California. A rest stop means ****ing on the side of the road. Every other state has decent rest stops but this entire state has maybe a dozen I have found over the years. -or- Road-Side Marker with Metal Pole and Cement Footing + Just add {pour} a Gallon Jug of Water with a Once of Salt in it on the base and around the earth. Pedestrian on highway ticket. Ready Make Mobile "Ground Clamp" : One-Half [Black] of a Set of 12 VDC Battery 'Jumper Cables'. -tip- Don't forget it whenb you leave. Learned that when drive in movies were popular and drove off with a speaker. An alternative would be to use a 30~45 piece of Bare-Copper-Wire that you roll-out and lay directly on the bare earth {ground} as a Counterpoise. Now you are getting where I want. Last pick your favorite 'remote' DXing spot and install a 4 Foot Ground Rod or a buried Bare Copper Wire Counterpoise for you to use when you are 'there'. iane ~ RHF . The last I can do since I have a favorite swimming hole that almost nobody knows about and is at least 5 miles from any kind of power lines or even people. Static free listening would be a virtual orgasm for me. Probably everyone else too. Bill Baka |

I did, but we sold the car, and the radio, unfortunately, stayed with it.

Not to mention most of the Korean stations that don't happen to fall on even 10's. I miss my shortwave.. in the car out on the open road is the only place in Korea that you have anything like a listenable band. I can imagine, I'm aware of your setup. After reading this thread I think I may put a receiver back in my car with a 108" ( I think) steel whip. That is the best antenna for shortwave that I found. I tried everything under the sun and the steel whip is hands down the best mobile shortwave antenna you can use, not many people though will drill a hole through their rear quarter panel - but I have and will. :-) |

Bill Baka Sony still makes some really nice AM/FM/SW radios for cars (with the requisite CD/MP3 player, etc.) that have, although not full coverage, at least pretty decent coverage. I will go look. A CD/MP3 player would be wasted on me since I prefer to listen to the sounds the car and road make while I am driving. Was going to look. The Sony home page won't work with my version of Firefox and IE will never be allowed to slime my drive. Maybe Egghead or Frys or some other large consumer place. As for the antenna, car radios are made to impedence match to the relatively short standard car radio antenna, and usually do not respond too well to additional antenna length. You CAN, however, place a variable capacitor between the car antenna and your random longwire, and tune it for best reception for a given frequency. This would at least give you the advantage of the extra capture area. As a rule when I buy a car one of the first things I adjust is the antenna trimmer, which is usually a bit off anyway. Funny how most people don't even know these things exist. - Thinking about it, - an MFJ tuning box sitting under the dash - should be a real conversation starter. - - Cheers, - Bill Baka They ask "What's THAT For ?" Your reply "Oh THAT Helps me to Hear . . . the Aliens Landing at Area 51."http://www.gamerevolution.com/images/violence/area_51.jpg *.- Hide quoted text - - Show quoted text - Ha! Yeah, back when I had my "fun car" with six antennas, I'd always hear the response from truck drivers. I had my regular car antenna in the front that I replaced with a larger - more sturdy antenna. I had three scanner antennas, one antenna each on the far outside corner of the trunk drilled through the trunk lid and the other antenna was a glass mount that I put directly in the middle of the rear window. Then I had a seven and a half foot skipshooter mounted (drilled through) right in the middle of the trunk and lastly - the 108" steel whip on the rear quarter panel. I think I may go more covert this time around, the only problem would be the shortwave antenna. |
