Your longest-lasting SW receiver?
Just curious to hear about shortwave receivers that people have owned that
are their longest-operating receivers. How long did they last, and are you still using them? Did they require major overhaul at any point during their long lives? Jackie |

Did they require major overhaul at any point during their long lives? The R8 I once owned worked fine for over a decade. The receivers I own now are in the single digits in years. The 7030+ display backlight is failing and I'll have to do something about it. Any advice appreciated about the display going dark. It looks like LED's are used for back lighting and they are failing. Some times they go on and off so it looks like cracked solder connections to the back lighting LEDs. The display is metal shielded so it looks like a project to take apart if it is possible to even do that without destroying the display. The Drake R8B no problems so far. The RX-340 had the bulb for the S-meter open. I replaced it with white LEDS. It looks great and I fiddled with the dropping resistor to it so the meter illumination and the other displays are balanced. Also had the receiver quit on me altogether at one point. That problem turned out to be cracked solder connections in the switching power supply board at the output connector. All I had to do to fix that was reflow the solder on the circuit board. -- Telamon Ventura, California |

Radio Shack Realistic DX 160. Bought new about 1976 and still runs as well as it did 30 years ago. Needed no repairs. Its not the worlds greatest rxr and has had more than its share of shelf time but I still drag it out from time to time. Original dial lights still work. Bob |

My old DX-440 from 1989 is still working fine, and I occasionally use it so that the kids will get a chance to play with it. The oldest radio that I own that still works is the Hallicrafters SX-100 Mk1, which I obtained last year. It's it pretty good shape; some recapping (which I didn't get to this winter) and some other work will bring it back to great condition. The Hallicrafters S-20R Sky Champion would have been working, if I hadn't gotten the idea in my head to replace the driver on it. It's been in a state of disrepair for the past 10 years. --Mike L. |

If you wanted to ask about medium wave, my 1916 Navy loose coupler crystal set still works fine, other than occasionally having to look for a new hot spot on the galena. ;-) P.S. Tip for SX-28 owners--watch out for the coupling capacitors on the 6V6 grids. If they go and you don't catch them in time, they could take out the (replaceable) 6V6s and the unobtainium output transformer. |

Dear Jackie,
On April 6, 1962 I bought a Lafayette HE-10 ($79.95) and its associated speaker HE-11 ($7.95) along with a pair of Lafayette headphones ($1.49). Being dissastisfied with those headphones, on July 27, 1962 I bought a pair of Clevite Brush BA-200 headphones ($14.79) and headphone cushions ($0.73). For over thirty-eight years, until I bought my Grundig Satellit 800 in June of 2000, this was my primary shortwave receiver. Except for a few tube replacements and a couple of full alignments (just to make sure!) over the years, it has always operated as it did when I first removed it from its box. Now owning the aforementioned Grundig and an AOR AR7030 Plus (factory-customized), I do not use the Lafayette much anymore. I ALWAYS use it on April 6, its "birthday," (It'll be 44 this year.) but, aside from reliability and its operation, which I LOVE - there's nothing like heavy flywheel-weighted tuning knobs (TWO of them in fact), its overall performance cannot compare to a modern receiver. But I'll never sell it! It's really nice to "fire it up" and relive my youth every once in a while. Over the years I tried to replace it, most notably with a Radio Shack DX-400 which I purchased in May 1984. But that set was not in the same "ballpark" as the Lafayette, digital tuning and triple conversion notwithstanding. Until I bought the Satellit 800 and then later the AR7030, I had not found any radio which satisfied me the way that old Lafayette did. My first portable shortwave radio was a Hitachi KH-1108S which I purchased on June 26, 1969. The only "servicing" this radio has had over the years is battery replacement (4 alkaline D cells last about three years!) and a thorough exterior cleaning which I did a couple of years ago - it now looks like "new" (except for the leather case which has hardened and cracked in places). I still use this radio, for local MW boadcasts - rarely for SW or FM, daily. Best, Joe |

Would you consider selling it/or trade selling it for something? I have an excellent RF-2200. Bob Grimes -- "What do you mean there's no movie?" |

the radio i had in my miss-spent youth was a beautiful 1947 firestone
console. it had 6v6 push-pull output, a great sounding 12 inch speaker and a built in rotatable loop antenna. it was still working great in the early 1980's until i met my wife. spending lots of time with her (you know, i had a new toy!) i neglected my listening for two months. that was just enough time for a family of mice to move in and destroy everything! i didnt know and the first chance i had to use the old girl was the last! the fire left no chance of a re-build. we held a solemn funeral later as my friends carried her still beautiful carcass out and laid her to rest. (it still chokes me up just thinking about it!) you never get over your first! oh well......i still have the wife, it was a good trade........i guess........ |

I own an Grundig sat 210 amateur( it was buitl between 1969 and 1973) ,
I bought it about 25 years ago. And it has 2 failures: 1 defect on first Rf stage : this is fixed. 2 ddefect switch for external antenna.By pushing the button down and locking it with a pin it works. Alll by all, in combination with my remote controlled remote mediumwave loop it is perfect : extrem sensible and a perfect audio.

Hallicrafters S-38EB radio and a Grundig AM/FM/Shortwave/Phonograph
wooden cabinet floor model radio (I say it was built by Telefunken because everything in the two little owners/operators pamphlets that came with the radio refer only to Telefunken as far as brand name goes,but on the front grill is a warped [warped from age,I guess] pot metal thingy that says Grundig and the only date I can find in only one of the two owners/operators pamphlets/booklets says 1957) and a Grundig Opus 7 AM/FM/Shortwave wooden cabinet radio. I dont know which of those three radios is the oldest.I still need to locate a power cord for my Grundig Opus 7 radio so I can try it out and see if it works,when I bought the radio at a Goodwill store,the power cord was missing.The other two radios (which I also bought at a Goodwill store do still work,but I dont doubt they need some recapping or whatever and a good tune up so they will work as good as new and I dont know how to work on radios. cuhulin |

Put a turned on flouresceant light bulb by your radio and,or your
computer and see what happens. Mississippi produces more electricity than we use in this state and last year there was talk about a new nuke plant in this State.Have y'all ever heard of power outages (other than power outages caused by stormy weather) in Mississippi before? This isn't California or New York City here. A few years ago,Duke Energy (or whatever the name of that Duke company is called?) installed a new steam electricity generating plant somewhere in the Jackson area. I dont mind spending more money for old style light bulbs.Those are the kinds of light bulbs I grew up with and I intend to use them for as long as I can. cuhulin |

But only failed when it was started. Therefore starting is the only reason why cars fail. HFguy uses same logic to 'prove' power cycling damages incandescent bulbs. He hopes you will believe sound byte reasoning rather than read many paragraphs of reality. As taught in Junior High School science, first we learn underlying principles before we can obtain a fact. Observation alone even proved spontaneous reproduction. There is no major shock to incandescent bulbs during power on. As well documented in so many light bulb industry publications, light bulbs are damaged by hours of operation - and as David so accurately noted - excessive voltage. Unlike HFguy, the industry even provides numbers for what causes light bulb failure. HFguy provides no numbers because he is promoting subjective speculation as facts. For example, a voltage increase causes a decrease in bulb life expectancy exponentially to a power of 13. Raising the 120 volts to 127 volts will cause a light bulb to fail twice as fast. These are industry numbers found in the same publications that list what causes light bulb failure. Power cycling is not listed in what causes incandescent bulb failure - in publications that use science rather than personal speculation. Once a light bulb filament is severely damaged (by hours of operation or excessive voltage), then even a so gentle power on may cause filament failure. Look at any light bulb that failed during power on. Before it failed - whether during power on or in constant operation - black residue from the filament is already apparent inside the glass. The filament is down to its last ten hour - like the car with over 200,000 miles. Hours of operation cause a filament to vaporize; those black deposits. HFguy makes claims by violating what was taught back in Junior High school. Without first learning underlying principles of how a light bulb fails, instead, he has proclaimed based only upon observation and wild speculation. He ignores junior high school science to promote speculation as if it were fact. Such reasoning also proved Saddam had weapons of mass destruction. Incandescent bulb life expectancy is determined by hours of operation and electrical voltage. Exponentially increase light bulb life expectancy by minor voltage reductions. If HFguy is so confident of his proclaimations, then he can cite an incandescent light bulb manufacturer publication. He cannot. He speculations are classic junk science - not found where reality is published. |

From the 'Great Internet Light Bulb Book': -WHY BULBS OFTEN BURN OUT WHEN YOU TURN THEM ON- Many people wonder what goes on when you turn on a light. It is often annoying that a weak, aging light bulb will not burn out until the next time you turn it on. The answer here is with those thin spots in the filament. Since they have less mass than the less-evaporated parts of the filament, they heat up more quickly. Part of the problem is the fact that tungsten, like most metals, has less resistance when it is cool and more resistance when it is hot. This explains the current surge that light bulbs draw when they are first turned on. When the thin spots have reached the temperature that they would be running at, the thicker, heavier parts of the filament have not yet reached their final temperature. This means that the filament's resistance is still a bit low and excessive current is still flowing. This causes the thinner parts of the filament to get even hotter while the rest of the filament is still warming up. This means that the thin spots, which run too hot anyway, get even hotter when the thicker parts of the filament have not yet fully warmed up. This is why weak, aging bulbs can't survive being turned on. |

The higher the Watt rating the lower the internal resistance. |

I found it! It was looking right straight at me all the time.My old
General Electric A-C Volts meter,that is.(the meter itself is in a little old style grey metal cabinet,I guess it dates back to the 1940's or 1950's,but it still works as good as new) It was sitting on a pile of junk on top of my bigggg olddddd antique trunk (can't see the tree for the forest is the way it is my house) near my dining room/kitchen door. (so was my Battery Cell Tester.MAC Quality Tools.Battey Cell Tester.ET2007.Mac Tools,Inc.Washington Court House,Ohio 43160) I plugged it in the wall outlet by my couch (oooops,Blueberry doggys couch) and it is showing a rock steady 120 volts (the needle isn't wavering at all) on the nose.Nothing wrong with my elecstwicyty here that would be causing my 60 watt G.E.Reveal incadescant light bulbs to be blowing out. cuhulin |

There used to be a G.E.factory here in Jackson that manufactured
incadescant and flourescent light bulbs.When my old buddy got out of active duty (U.S.Navy) back in the mid 1960's,he worked there for a couple of years,then he got a job delivering the U.S.Mail.(he retired from the U.S.Navy Reserves unit here in Jackson [about 30 years or so] and the U.S.Post Office too) I dont believe G.E.makes crappy light bulbs.I own quite a few old G.E.tube type and transistor radios and most of them work ok.I will keep on buying and useing G.E.Reveal 60 watt incadescant light bulbs as long as the stores keep on selling them.By the way,I noticed they sell very well at the local Jackson stores around here,even though there are tons of flourescent light bulbs sitting next to the G.E.light bulbs on the shelves.(in Jackson,we like REAL Light Bulbs) cuhulin |
