.... For those of us who became interested at the time of the
transition from thermionic devices to semiconductors, that in 1965 a household might have less than 35 active devices in total (25 in the colour TV, 7 in the transistor radio) and now we have countless millions mostly in computerisation of one sort or another. Is it, I wonder the degree of integration in off-the-shelf electronics that is the prime cause of the lack of technical acumen and interest in home construction to be found these days, especially in the under-educated NuHams who cannot even tell one end of a resistor from the other? |

Coming from someone who was afraid to attempt to use a basic amateur transceiver due to a few missing pages, your comment is the height of hypocrisy. After all, many of your vapourware projects tend to be rather biased towards older, simplistic, equipment- including things which are not even active and were more typically perhaps 'novelties' over a century ago. The type of thing many of us experimented with as youngsters but have since progressed beyond. What was that analogy about amateur radio being a vast pool to explore- not much point if you keep sitting on the side with your toes in the shallow end talking about getting in- especially if you've been doing that for 45+ years. Nowt wrong with vintage radio Brian. Why do you belittle those with an interest in it? I note that you don't abuse your chum for his interest in vintage computing. |

I wasn't referring to vintage radio. You lack of technical knowledge has let you down, as usual. Read your own post again. |

That might account for recent things, but it took some time before surface mount and really integrated ICs came along. And don't forget, most of the semiconconductor manufacturers from 1970 have either changed drastically, or the division sold off. Yes, it is fascinating that the average home had so little electronics in 1971, and then circa 1975, there was an endless flow, if you didn't have it, you thought about it. That is a major shift, and suddenly all kinds of things that could cause interference, and all those clocks added in because it cost nothing to add a clock function once the electronics were designed (so you'd end up with clocks all over the place, none having the same time, which then caused "atomic clocks" to become popular much later when they became cheap). But the introduction of ICs were a really great period. Lots of interesting analog ICs, and they kept coming. There were some great RF type ICs, which in the end died off because demand wasn't there, or later shifted to other techniques. But those National and Plessey ICs in the early seventies probably increased building, a shift where "simple receiver" went from a regen to a superhet, because the ICs made it simpler. But circa 1971, the IC market was often for the non-consumer. It slowly shifted to the consumer, which meant more and more specialized and concentrated ICs that had little use other than in a specific circuit. But the money was there, consumer electronics sold in way larger quantities, and they needed it. A ham rig was too specialized, high integration could bring the price down only so much, but save some money on a consumer piece of equipment, and the price dropped quite a bit, which was made up in large sales quantity. Any consumer device, they started out expensive, big and using standard parts. That applies to that dot matrix printer I got in 1982, any early VCR, or early cellphones. You could open them up and see standard parts, not just through-hole devices, but CPUs that were recognized and fairly low integration devices that could be used elsehwere. But to bring prices down for the consumer, they had to ramp up and manufacturing had to decrease in cost, so they moved from metal to plastic and used higher integration devices. So that equipment is fairly bare now, not loads of ICs on multiple circuit boards. But they are also very much machine built, since that's way cheaper. And repair is too expensive, compared to the cost of the item. Now things have changed, but this is about 50 years after the IC showed up in hobby circles. Fifty years before that it was 1915, radio barely going anywhere, tubes used only if you had the money and you were lucky. Another fifty years, and things will likely be very different too. SOme of the failure is more attitude. "We can't compete with the internet" say the old men who forgot what it was like to be a kid and learning about amateur radio for the first time. You don't compete, you present the alternative. "Kids today use technology all the time", but it's a mainstreamed technology, it's not about creating something or doing something different, it's not even really about technology, it's about using very advanced gadgetry. I knew someone who always complained about "technology", but she drove a car, and the minute she got home, she'd check her answering machine, and she was tied to her landline phone. SHe was very mired in technology, except those things were mainstream. Computes and cellphones and whatever have now become that sort of thing, people get to be cool because they have the latest iPhone, but there is a big difference between their skill with "technology" and some kid forty years ago. Now, they are users, maybe more skilled than some, but they don't really know technology. The kid in 1975 learning about computers knew a whole lot more. The minute people say "hams don't build anymore" is to be part of the problem, because it's not true, even though it's now more hidden. But if you start from that attitude, then you get real problems, like with QST shifting technical articles elsewhere. They'd run articles on parametric amplifiers and moonbounce and really down in the noise receiving techniques, and whether or not most readers ignored it, it was there, no extra step needed. Now they have "QEX" that costs quite a bit, and even more if you aren't an ARRL member, and it has the technical articles. When they aren't in front of you, then it's easy to be somewhere else.

Due to the availability of low cost micro controllers and computing modules there seems to be an upsurge in home construction related to electronics ,be it not necessarily ham radio . The Makers World often focussing on robotics using cheap sensors ,Arduino , Raspberry Pi is alive and kicking and even rapidly expanding. The Makers really know how to use electronic components . In the ham radio community there are also groups of active "homebrewers" although they might not hit the headlines any longer. In ham radio , for most licensees ,the prime focus is on operating and because of the availability of ready made equipment , often with an acceptable price for many , home construction in ham radio overall has steadily been in decline since WW2. That is a fact and IMHO there is no reason to keep moaning about it. Frank GM0CSZ / KN6WH in IO87AT (a ham radio homebrewer) |

My name is John Doe. I live in Dopey Dumbsville Alabama. My rig is an XYZ123 for which I paid 2345 dollars to the local emporium. The antenna is a Butternut Squash. I have neither interest nor knowledge in how anything works because if it goes wrong the said CB emporium will fix it for me. It's been nice metting you, 73 and goodbye" |

There is every reason to speak out against the dumbing down of a proud technical pursuit I take it obtaining an amateur radio license is your only notable accomplishment in life which would explain why you are such a self rightous ass hole. Here's a news flash for you: Children were passing the tests over 50 years ago when they were much more difficult. Passing such tests shows nothing more than you are willing to put forth the effort to learn a subject; it does NOT make you any better than anyone else. -- Jim Pennino |
