Building a new shortwave tube radio
Wow, I lit a loaded fart off here, didn't I?
First, I said use a Hallicrafters band switch and an Eddystone dial because there's probably a market for those with old Hallicrafterses with bad bandswitches and with regen builders respectively. The problem with the Hallicrafters band switch replacement market is that there are so many DIFFERENT ones, if they were all the same they'd be reproduced. Remember rotary switches are modular, to a degree, the company that makes them builds them out of mostly off the shelf parts, and in fact you CAN get new ones built, but the problem is that they cost more than the value of most hallicrafters radios, since they have to put them together as one offs. 500 units takes the price from $400 to $25-50 each. At twenty five bucks a shot you could sell a couple hundred in six months....IF you had a unit that went into enough popular radios. Eddystone dials are a similar thing. The market has to be a mix of nostalgia and survival mentality. Yes, a solid state radio can be made EMP proof, or highly resistant, but it takes some doing. As far as power in such a situation....In the old days they used car batteries for heater voltages and a stack of dry cells, a dynamotor or a vibra-pack for B+.. Look carefully at the old Collins and National sets. They developed it to something of a fine art. As an aside, any "survivalist" with half a brain has buried a couple of solid state complete radios as well as a pile of surplus semiconductors useful post-Blast in old ammo cans. A stash of common bipolar and FETs, silicon diodes, common chips for radios and whatnot, buried under ground could be more valuable than gold and at a hell of a lot lower current acquisition price today. Some discussion on which types would be interesting. I don't consider myself a survivalist but I have a couple of guns and some ammo buried along with a couple of full jerry cans of 100LL avgas (it doesn't go bad) and some electronic stuff, plus some garage sale Craftsman tools, some spools of wire from a motor shop (short ends), and a couple things I won't mention. Better safe than sorry I figure. |

Australia got stupid with its gun laws when they let the 'sheilas'
vote. We got Prohibition under similar circumstances. Female suffrage was a great idea...NOT! |

That simple, since there's only a few tubes. 9v "transistor" batteries in series. It doesn't take that many to get reasonable B+ and since tubes are low current, it's reasonable. Of course, towards the end of the life of tubes, one could get some that ran off 12v, intended for use in car radios. Not so useful now since they were produced in a limited time span as transistors were taking over, so quantity is relatively limited. The R392 ran off 24 or 28 volts, using those low plate voltage tubes. Of course, it had a lot of tubes so the filament drain was large. Of course, some people experimented with low voltage on regular tubes. A loss of gain, but sometimes that was a good thing. Michael |

You need to be more cautious and critical of Internet and media hype. And you need to make sure you're not talking to someone getting his information first hand from the legislators voting on the bill. I don't ever blindly take anyone's characterization of something. I read the text of the bill. http://www.legis.state.la.us/billdat...asp?did=760886 Which, as it explicitly says, amends and reenacts (among other sections) RS 37:1861 http://www.legis.state.la.us/lss/lss.asp?doc=93498 However, to your implied innuendo, one would hope the author of a bill understands it better than a web blog. The broad definitions of 'second hand retailer' virtually expands the limits of interpretation to include flea markets, garage sales, and one on one cash transactions. http://www.agcrowe.com/pg-51-15-pres...px?pressid=526 That doesn't mean I 'take his word' for it either but, I'll tell you one thing, I can find HIS claims in the actual text of the law. It does not apply to non profits, flea markets, garage sales, persons solely engaged in the business of buying, selling, trading in, or otherwise acquiring or disposing of motor vehicles and used parts of motor vehicles, or wreckers or dismantlers of motor vehicles, dealers in coins and currency, dealers in antiques, gun and knife shows or other trade and hobby shows, and, well, anyone who isn't a "secondhand dealer" Actually, these are specifically what the law is intended to address. Says WHO? As I said, one of the legislators voting for the bill. I'm in media. I frequently interview legislators about their intents, and their actions. I've been attempting to get the Attorney General on the line to explain how this law affects street level commerce. Louisiana has been attempting to get control of cash transactions since I lived there in the 80's. They also attempted to ban owners' self repair of their own cars through similar legislation. It's an interesting state. More a foreign country than a State. Where the limits of the Constitution appear not to apply. And with this bill, 'legal tender' of the United States becomes illegal to use within the State of Louisiana. A court test is being prepared on this matter. Expect significant debate locally on this. If not resistance. My compendium of who it did not apply to is a collection of quotes from enacted law prefaced by "B.... the provisions of this Part shall not apply to." For example, the text beginning with "persons solely engaged in" comes from page 2 of 8 of Act 389 (amending RS 37:1861). The remainder comes from the unamended portion of RS 37:1861. I.E. The text beginning with "dealers in coins.. " is item B (1). Actually, the "persons solely engaged in" could have been quoted from RS 37:1861 because the only change was [licensed under the provisions of] "32:783." They're simply trying to disrupt the sale of stolen goods through secondhand dealers by requiring said dealers to use traceable payments in their purchases and keep records identifying the seller; and even if there were no 'exemptions' it applies only to secondhand dealers and has nothing to do with 'consumers' because they are NOT "secondhand dealers." Agreed on that point. But the language of the bill is sufficiently broad to allow interpretation beyond commercial interests alone, to include persons conducting flea markets, garage sales, or one on one transactions. To the degree that it's had a chilling effect on flea markets on the local level, in areas where economic distress has made flea markets a significant segment of the shopping culture. |

Building a new shortwave tube radio
You're making too much of an assumption. *The cheap receivers used off the shelf parts. *But better ones used custom parts. *Design is a tradeoff, and *using off the shelf bandswitch meant layout was determined by the switch. *Making their own, they could do what was needed for best design, the cost might be higher but it's offset by ease in the rest of the layout. *Which is why you can't make a bandswitch that will fit all the receivers from even one manufacturer. There were Eddystone dials because the company made them for their receivers and then happened to sell them as parts. *Hammarlund made parts, they were well known for their capacitors. *National sort of, but then they had Millen as a sort of manufacturing arm. But if you wanted to use the bandswitch from the Hammarlund SP-600, you'd have to follow the layout and design very carefully, since the turret bandswitch was a key part of the receiver. You're stuck with how many bands the receiver had, you're stuck with their layout, you're stuck with *using the same sort of design as the original receiver. Which was good, basically. Hallicrafters was profitable-see Ed Romney's discussion in his book. We want 500 kHz to 30 MHz in four or five bands, which was de rigeur for general coverage receivers. A bandswitch is troublesome, and bulky, and in good receivers, expensive. Which is why when solid state came along, there was a trend to do as much bandswitching through DC as possible so the switch just had to control DC and didn't have to be near the circuitry. *Hence diodes were used as switches. *Relays sometimes. *People saw that the cost of an active device was so low, it was cheaper to duplicate oscillators than use a bandswitch to switch coils and crystals. *There again, it looks like a bad move cost wise, but if the benefits are sufficient, then it's a good move. *The bandswitch becomes simpler (so no special part needed), the layout becomes simpler. Ray Moore once had an article in Ham Radio about receiver design. *It was nominally a description of a mostly AM broadcast band receiver he'd built.. But he made the point that a commercial receiver has to cut costs, since each component is multiplied by however large the run is. *For someone making their own receiver, the cost of an extra bypass capacitor is only five cents, or whatever, and no overhead on that extra capacitor. *It's simpler to add components if it makes the design simpler, rather than cut components and deal with the issues. *So having three IF stages rather than two is not that big a deal cost wise for the home builder, but having those three stages running at less gain than if there were two makes layout simpler. Can you cite the article? It'd be informative. I can get it from the library. As far as power in such a situation....In the old days they used car batteries for heater voltages and a stack of dry cells, a dynamotor or a vibra-pack for B+.. Look carefully at the old Collins and National sets. They developed it to something of a fine art. Those are horrible models for the homebuilder. They were exceptional receivers, but they are also built like tanks. *The more expensive the receiver, the more shielding there is inside (in part because it's good design, but likely also a reflection of their more complicated design). *Some of those receivers are awful to repair, since you have to pull out layers and layers of pieces to get to the section you need to deal with. *Some of that is fallout from the need for a central bandswitch. You can't duplicate them unless you are willing to make copies, which are beyond what most are capable of. * * Michael The S/Line was not "built like a tank", but it was innovative and of good quality. The R-390s and the A-line approach that designation much more closely, as do Stoddart RI-FI measuring receivers and certain Mackay Marine and Racal sets. S/Line was inspired by Art Collins' purchase of a M series Leica camera, well built but also stylish and compact. There was in fact a company that DID clone S/Line, except the cabinetwork was kludgy by comparison. This is analogous to the Hickok and Jetronix clones of Tek tube scopes-they weren't quite as good but still way better than service grade scopes. |

You might have a different opinion if you were burglarized and all your stuff was sold by 'private transactions' through a second hand dealer front man. Btw, the information only becomes available to the police in the event of a criminal investigation and it's only that transaction. There is no routine 'reporting to the government'.

Regards, JS I take it your definition of "imbecile" is "not a thief." Intelligent thiefs are never caught, so difficult to analyze them There is, no doubt, a good chunk of the prison population that thought the same thing. ... or else they are criminal public servants and all have get-out-of-jail-free cards provided by their rich corporate, bankster, wall street puppet masters ... so, you have a point, they are just well protected imbeciles ... Sounds pretty 'smart' to me since, according to you, they've got you beat. Regards, JS I should have known it would be too difficult for you to connect the dots, so let me just give you the answer ... The intelligent crooks, perverts, child molesters, intern molesters, treasonous terrorists, economic terrorists, etc. are illegally holding our public servant offices and displaying their get-out-of-jail-free-cards. Regards, JS |

You might have a different opinion if you were burglarized and all your stuff was sold by 'private transactions' through a second hand dealer front man. Btw, the information only becomes available to the police in the event of a criminal investigation and it's only that transaction. There is no routine 'reporting to the government'. Isn't that the reason we initially hired "cops" for? What is the 'reason' you are mysteriously alluding to? I mean, I realize they are no longer doing a job for the people, the citizens -- and are mostly revenue generators for the town, city, county, state, feds, etc. Just how does a murder, burglary, theft, etc. investigation 'generate revenue'? But, really, watching every dollar trade hands is NOT what we have public servants and authorities for, And the bill doesn't do that, even for the limited group "secondhand dealers" it addresses. It requires them to keep their own records, which is no more information to no more people than the persons involved in the transaction. The only occasion for government to even know a transaction took place is in the event of a criminal investigation. we don't have them to "punish" us Depends on who 'us' is. 'Punishment' is pretty much the whole concept behind a prison system. ... we simply need to remind them to do the original job they were created for You mean like search and seizure police powers? Of course, if you're a criminal the best thing is to not keep any records they can search and seize, isn't it? On the other hand, knowing who you're dealing with is pretty much SOP for legitimate business even if for no other reason than they don't want to be screwed by some fly by night huckster. and the things you mention are already taken care of ... And just how is it "already taken care of" when a criminal front man doesn't 'know who' he bought the stolen goods from and paid cash so it's untraceable? I suppose we could go back to the bright light and rubber hose methods. let's just get the public servants and cops to do the job for the people. I don't know what 'job' you have in mind since criminal theft rings seem to be off your radar screen. But let's get one thing clear. I never said this particular law was well worded, 'ideal', or even adequate. All I said is that Internet and media hysterics misrepresent both the intent and functioning of it and your "watching every dollar trade hands" is an example. But, to the point that started this sub thread, there is nothing whatsoever in that law which requires any seller, secondhand or not, to get the 'identity' of a --buyer-- (of a radio or anything else). Btw, it isn't just the poor schmuck who got robbed that's screwed because, no matter how much 'good faith' you had in buying, if the 'used' radio you bought from the "secondhand dealer" was stolen it isn't yours. It goes back to the rightful owner and you're out whatever you paid for it so Mr. "Don't know who and paid cash" is screwing you too. Regards, JS Gee, just when we thought we had enough, another complete imbecile ... how special ... Regards, JS |

How do you propose funding government and, besides that, how do you expect government to protect your property rights, such as your home, if they don't even 'know' you bought/own it? They are here to serve us, I'm curious. How did you arrive at the theory that banks and corporations, which are simply people engaging in "private transactions," are "here to serve" you? not the other way round. They are the peons, and we are the rulers -- not the reverse. They have no right to know ANYTHING about our transactions. Ya know, that's what Al Capone said too.

I doubt, however, that a generation of cowed and bowed dependents and yes-men can produce such a thing. With every good wish, Btw, strange and mysterious as it may seem I actually agree with the nebulous gist, if not the details, of your point and, in that light, let me mention that the theory to our form of governance holds that governments do not have "rights" but are granted "powers." So, you are quite correct in saying government has no "right" to know about transactions, or anything else for that matter. The question is what powers we wish to grant them for the purpose of our mutual benefit and security. Like, in this instance, to be secure from having our property stolen and fenced through 'secondhand dealers'. Kevin Alfred Strom. Well, true to form, you continue down an idiots path ... the public servants are the treasonous crooks, the rich elite, corporations, NWO types, etc. are their puppet masters ... neither are serving me. Anyone, other than rich elite, corporations, NWO types, etc., who thinks they are are serving them are imbeciles along with you. Regards, JS |

Even rarer were tubes that drew almost no current. They used "cold cathodes" so they did not need expensive (in terms of current and heat dissipation) filaments and had low plate voltages. They came out when transistors where just starting out, but rise of transisitors was so rapid and transistors were so cheap in comparison, that it was simpler and cheaper to build a 7 or 12 transistor radio than a 5 tube cold cathode one. They showed some promise in the missle and space exploration systems of the time, because transistors could not stand the temperature extremes or cosmic radiation they would be exposed to. That also did not last long, as improved "space grade" transistors came out. What really killed them was NASA's adoption of the new integrated circuits (which actually pre-date the "space race"). Cold Cathode tubes were voltage regulators, displays, etc. I have never seen a cold cathode amplifier. Between miniature tubes and solid state there were Compactrons, which were several tube stages in a single envelope. There was also the 'Nuvistor' http://en.wikipedia.org/wiki/Nuvistor |

With every good wish, Kevin Alfred Strom. --http://nationalvanguard.org/http://kevinalfredstrom.com/ Wow. I remember listening to YOU-and Dr. Pierce-on the first regen I ever built when I lived in Texas, about ten miles from the Louisiana line on that shortwave station the NA bought time on. I did not always agree with what you said but I damn sure backed your right to say it. Pierce was really an intelligent person. I read the biography on him by Robert Griffin, great read. Louisiana is a seriously warped state. Texas was screwed up in some ways but Louisiana with its nightmarish hodgepodge of laws built on four different legal systems and general laissez-les-bon-temps-rouler attitude is Third World. Regens are a pain in the ass. The best regen ever built was probably the National SW-3, or for low frequency work the old Mackay Marine set. Lindsay is full of **** when he says the homebrewer can better it with moderate effort.And even so any mediocre superhet will outperform it in some ways. My late forties Zenith console will separate stations the SW-3 won't. But they are interesting to build-once-like the crystal set, which can be run into a hi fi amp and give good local station performance. My regen was the two tube set in the Romney book which Lindsay also published. The SW-3 was far better-it would copy ham CW on 80 and 40 consistently and even SSB with a good signal. The homebrew was good for WWV and Radio Havana and that was it. |

You're way late to the game, then, because there's nothing in the bill that "expands the limits" to "flea markets, garage sales, and one on one cash transactions" more than the already existing law. Your selective attention is interesting. It's the broadness of the language that expands the limits. Because the broadness of the language does nothing to limit the definition of the terms. And, one more time, the legislators voting for the bill specifically intend for the law to include garage sales, flea markets and one on one cash transactions. This by their own admission. As I said, one of the legislators voting for the bill. I'm in media. I frequently interview legislators about their intents, and their actions. I've been attempting to get the Attorney General on the line to explain how this law affects street level commerce. No offense intended but none of that means anything. What legislator, what did he say, and why would I presume he knows better than the author? And why should I take 'your word' or 'opinions'? Well, that IS the crux of the argument, then, isn't it. Louisiana has been attempting to get control of cash transactions since I lived there in the 80's. What in the world does that mean? Just 'who' is "Louisiana?" Maybe they shouldn't vote for "Louisiana" next time if Mr. "Louisiana" supports wacky things. Wow. Obfuscation 101. This discussion has suddenly become a waste of bandwidth. Bottom line...I've lived there, you haven't. I deal with the legislators in Louisiana every week, you don't. You're entitled to your skepticism. Enjoy it. Have a good evening.

Sooner or later they do get caught, because they get greedy and or sloppy. Look at Leopold and Loeb.. Two really intelligent individuals who got the idea to kill someone to see if they could. The local cops had them in jail in no time at all even though the average cop back then was a dumb****. They narrowly escaped execution because Clarence Darrow defended them. |

Of course, towards the end of the life of tubes, one could get some that ran off 12v, intended for use in car radios. *Not so useful now since they were produced in a limited time span as transistors were taking over, so quantity is relatively limited. The R392 ran off 24 or 28 volts, using those low plate voltage tubes. *Of course, it had a lot of tubes so the filament drain was large. Of course, some people experimented with low voltage on regular tubes. *A loss of gain, but sometimes that was a good thing. The R392 used conventional tubes selected for performance at 24 volt B +. 24 volts isn't much but is a lot better than 12. The 12 volt tubes were space chrge affairs and were current hogs and delicate. |

Hate to say this but you are doomed to fail from the start.
Why? There are PILES of tube type SW receivers available now FAR cheaper than you could build one. Hey, I get it. It'd be a fun project. I've thought about doing something like this myself but seriously consider the cost. Not just of the parts but the time involved in the design, marketing, and *liability insurance*. Bet you didn't think about that one! Steve |
