Well, things have not gone as one would expect...
And, they may well be due to rules, regulations, and mindsets... and, specifically, ones generated from an "American mindset." Now, there is the "rest of the world" as we move to "globalization" these ideas here will hardly set the course--I have afraid our part will be more of passenger, as opposed to a captain... the best I can see is, using our "paddle" we are able to affect a slight course change in our favor... If one of your arguments is, don't propose any ideas until you have a complete working design--I see that as more an answer to my original observation... progress remains slow-to-halted, that simply being one of the contributing factors... If you seek to give a list of "why it can't work", that is helpful, but, bear in mind, I was looking more for a list of "why it can."

I see it as EMPOWERING homebrewers--far from the opposite!!! | | As others have (I think) pointed out, there are some very valid | technical and regulatory problems which might make this approach less | than popular. | | Here in the U.S., at least, transmitters in most of the radio services | have to be "certificated" (previously "type accepted") by their | manufacturer, demonstrating that they comply with the operational and | emissions rules for that service. In these services, almost any | physical modification of the radio will invalidate the certification, | and make it technically illegal to use it to transmit. Modifications | which don't violate the certification can only be made by technicians | or organizations with a specific license, and (I believe) may require | a significant amount of re-testing to demonstrate that the radio still | meets the requirements. | | The FCC rules don't provide for the arbitrary swapping around of radio | cards in such transmitters. | | Also, there's a tradeoff between modularity, and cost/performance. | The more modular a radio (or computer) is, the greater the number of | gozintas and comesoutas (i.e. signal connectors, busses, etc.). These | add cost, they decrease reliability (compared to a soldered | connection), and they limit the degree to which one can take advantage | of increasing degrees of device integration at the chip level. | | The highly-modular PC infrastructure has gotten to where it is, in | terms of price and flexibility, because of the extremely large number | of units produced - there's a lot of "economy of scale". This is due | in large part to the fact that consumer, business, and industrial | applications can all use the same architectures. People have also | been extremely eager to take advantage of higher-performance | components and have been willing to accept relatively short product | lifetimes as a result... and this increases the demand for a "change | out part of the system and keep the rest" solution which demands | modularity. | | I don't think that the same environment exists for radios. Commercial | and public-safety radios have a long lifetime, they have the need for | physical ruggedness which may discourage the use of a "plug-in" | architecture with lots of connectors that can shake loose, they're | rather cost-sensitive, and for regulatory reasons they probably cannot | adopt a "Users may change out components" architecture. | | In these radio services, a "You buy it, and it never changes" | shrink-wrapped monolithic radio design simply makes more business and | economic sense. | | Things may become a bit more friendly in this regard, at least for | base stations, with the newer "software defined radio" architectures. | However, in commercial and business services, the FCC insists that the | systems be designed and built in a way which prevents users from | making arbitrary changes to the configuration which could violate | regulations. One example of this is the Atheros 802.11a/b/c wireless | radio cards... their behavior is very strongly defined by their | firmware, and the vendor says that they *cannot* release the firmware | or low-level drivers in source-code form for fear of violating the | FCC's software-radio rules. | | Frankly, I think that the amateur radio service is probably one of the | few services (and perhaps the only one) in which a general-purpose | "radio card plug-in" architecture or system could be generally useful, | and the resulting radios would probably be significantly more | expensive than monolithic-board or proprietary-bus radios of similar | capabilities. | | Due to the limited size of this market (compared to business and | public safety) I doubt that you'll see the big manufacturers invest | the time and money required to develop and promote and market such an | architecture. No sense in their doing so. Without the leverage of | being able to use the same technology in other radio services, it's be | a big investment for no return. | | Indeed, if some were as gifted as all that, they need only buy the case and | some foil boards/components--when they emerged from the basement--I'd expect | to see a radio of their OWN design in their hands!!! | | And there, I think, you've defined the only market to which such an | architecture would be strongly attractive - hobbyists. | | There might be enough of a community there to support the development | of such an architecture, just as there are communities supporting the | GNU software radio, the RockMite, and other specialized radios. | | Feel free to propose a design, John Smith! If it's as overwhelmingly | good an idea as you seem to think, maybe it'll take over the world by | storm! | | In short, John, I don't think it's fair to say that there has been "no | progress". Rather, I'd say that things haven't gone in the direction | you suggest, because your solution is one which solves a problem which | most people don't feel is worth solving, and comes with a cost that | most people don't care to pay. | | -- | Dave Platt AE6EO | Hosting the Jade Warrior home page: http://www.radagast.org/jade-warrior | I do _not_ wish to receive unsolicited commercial email, and I will | boycott any company which has the gall to send me such ads! |

You miss the point, I expect the cards to cover the planet... our present
way of thinking enslaves us to "our beloved componet" or, "our beloved manufacturer", time for a change... I suspect, in the future problems will arise and be delt with--just recently I had to do a "kludge" and replace a 6cw4 with a fet... who knows what "fixes" will be forced on those of the future...

You can't see the forest for the trees. There isn't a big enough market for what you want to EVER bring the price down to a reasonable level. You can't do anything without some initial specifications. You have to do research on available parts, cost to tool up the metalwork, and liability for your design. You mention a "PA" implying a transmitter module. You talk about "manufactures of the modules" This brings the FCC, UL, and other testing costs and problems. You have no idea what you are talking about, unless you have worked to design a modular system. It can easily triple the cost of the design. Then there is software compatibility. You have to set strict standards for each module, or one "X" module won't work with someone else's "Y" module. How about the GUI? who is going to write a new one for every combination of modules? Or do you plan on having a couple dozen separate programs on screen at a time for each function? have you ever designed a complete radio system?

I'm all too familiar with finding replacements for obsolete parts. Both in manufacturing and repair. There is a mature product on the production line. Purchasing comes running to the production manager to tell them that the last manufacturer of a line of components has just dropped the whole line, and we missed the "Lifetime buy" option by a couple days. Do you drop the product, or do you redesign it? DO you spend days or weeks tracking down surplus parts through a broker that may or may not be good, and risk bad PR when they have a high failure rate in the field? Been there, done that.

I don't think the "apple boys" had ever designed a complete computer before
they did--indeed, don't remember anyone else (or team of engineers, techs, scientists, etc...) doing a desktop before then... You mean, China, Russia, India, USA, Canada, So. American, Mexico, etc--and every gov't, business, private individual, ham and cb'er... is not a big enough market... these things would be manufactured in China yanno!!! Kinda like Mac's and IBM's, yanno. Lets face it, it is most difficult to buy American computer boards, memory, etc--these radios would be the same... the computers are already made there, we would just be giving them one more task...

Have you ever looked at the schematic for the Apple II? It was bases on the MOS technology 6502 processor and support chips. Its probably the simplest "Computer" ever sold and most of the design was in the IC data books, just like the original IBM PC was quite close to a sample design published by Intel. The only real difference was that the design was broken up into modules. Neither of the original designs were anything to brag about. Monochrome displays, Apple's half assed "custom" floppy disk interface that threw away most of the capacity to keep it cheap. The PC was shipped with a cassette interface and no floppy drive. It had BASIC in ROM, and was fairly useless until floppy and hard drives were available to do any real work. If you think this is an easy project its time to put up, or shut up.

So, although your original argument was how difficult a bus and keeping
analog seperate from digital which would share various signals--would be, then, when the argument was made that someone just picked up a bunch of on-the-shelf items and went ahead and done it... you flip-flop--to where now it was so obivious someone should have done such a simple thing LONG before them... Yanno, you are pretty obivous here--you are like what has been "the standard method of operation." A long list of why it can't be done--but if someone can--its' easy!!! Or, first it is impossible, then, once someone has done it--it is nothing... Now, that is comming close to a "Troll!" And, that would be proven if once this is pointed out to you--you use that for a reason to spur more conflict... Arguments and debates for the purpose of looking over what is available--of reaching a logical and organized ideas--are good--argument for conflict is not... While some may take pride in finding all the reasons why something is difficult--or may end up to be "un-do-able" right at the immediate time... It is the guys who ignore all this and go ahead and do it which are remembered... For every thing we have in this world today--there stands inventors, engineers, technicans, etc.. who could have easily decided it was either too hard or impossible and given up--thank gawd they were of a different breed...

Which Apple computer do you mean? The Apple II? Steve & Steve built the Apple I before then (you can do see one down at the Computer History Museum in the bay area if you'd like) and I'd bet a nickel they had built other folks' designs prior to that (e.g., the old Rockwell KIM, perhaps some of the popular S-100 machines available at the time, etc.). It was "revolutionary" in a sense, but much more evolutionary from a dry, engineering perspective... but then again, almost everything is if you look closely enough! |

Well, I am not even ready to argue that point...
You missed the point... what I propose is simpler... it is a radio--not a computer... and still can be done by those who ignore the nay sayers, no matter how loudly these nay sayers attempt to shout down progress... I feel like a pimp in an old age home with hookers, no takers and everyone there wonders why I am there proposing the ideas I am... grin Warmest regards, John -- Sit down the six-pack!!!

Nope the entire world wide population of hams is NOT enough. The US has just under 700,000. Japan has somewhere around 1 million (there numbers are hard to determine due to their licensing system). The remainder of the world combined has right around the same total of the US. This gives a worldwide ham population of under 2.5 million. So starting from that rough estimate, let's look at some figures. Very, very few people buy a new HF rig annually. Just using the people I know, it's more like every 5 to 10 years. So let's use an average of 7.5 years. That means a total of 333,000 new radios (rounding off the answer) sold in any given year. Now split that between 3 makers, yielding 111,000 units per maker. That's pretty low volume to undertake radical development. We're probably lucky that we get any new features. Dee D. Flint, N8UZE |
