Warmest regards, John Not sure how restrictive your idea is, but it ain't new. You can even find the odd receiver on e-bay with cards for each function plugging into a bus - try Plessey for example. Even the ancient Davco DR-30 and the first solid-state heath transceiver (SB401 IIRC) used plug in RF, IF etc cards. Several modern scanners, especially portable ones have a selection of optional plug in cards for things like, extra channels, digital decoders, tone squelch etc. etc. I had an early Yaesu VHF/UHF receiver which had an optional plug in card video decoder. My Kenwood R-5000 has provision for a plug in VHF front end. I used to have a RACAL receiver, old enough to be antique now, which used plug in front ends for various coverage options, and I seem to recall it was a fairly common idea in those days. Dave |
Len Anderson gets it right. Roy gets it right. Several others show that

He is just another hopeless wanabee who doesn't understand anything about the real world. Tsk, he's a poseur, an imitator, a wannabe who needs a "rep." :-) Len, I have worked from DC to 11 GHz on commercial designs and anyone that thinks any design is easy just doesn't have any idea what's involved. A problem in discussing things in diverse groups is that the vast majority does NOT have such experience. [there's a short pause while a few regulars become overheated with indignation... :-) ] The vast majority get their "experience" from READING about it - AFTER all the development fuss and fury has been done. If the writers and editors are good at words, they create the fantasy that the reader has been there "too." [there's a whole lot of 20-20 hindsight going on with those readers] Its one thing to hack together an almost working prototype, but its a whole different animal to design from the bottom up to meet set specifications, make sure the components will be available, and if the unit is to be sold, to make sure that it will clear the FCC, UL and other requirements. If you decide to manufacture the equipment for sale outside of the US you have the CE certification, and ISO 900X to deal with. You said it, brother! :-) The PR splashes and articles in QST just do NOT go into days, weeks, months, week- ends, deferred days off, sweaty times on the bench with "stubborn" things (finding out little annoying things one might have forgotten to include) or finding that a component is NOT in tolerance, "fix" days in having to work around a problem caused by someone ELSE not doing their job quite correctly and being stuck with finding the cure. Neither does it include some total fascination in seeing a creation come to LIFE, bit by bit and working AS designed, the pride in one's self for having done so (a quite kind, most satisfactory, adding one more mark on self-confidence). It is a satisfaction in having been given an arduous responsibility and achieving success in meeting it. Besides, it can be fun! :-) It would be interesting to set up a group to develop a modular system, but getting people to agree on the specs can be more work than the actual design. Actually, in this rather lengthy thread, which has no real consequence to hobby electronics, there really wasn't any "need" to "develop a radio specification." It was a mild rant by an anony-mouse who hasn't been there in real life and wanted to become some kind of newsgroup age Keroac a la four decade old "protest" movement. "Putting together specifications" has been done for centuries. It is never easy because too many chafe at "being told what to do" or expect that every spec is "perfect, something that must be adhered to at all costs!" Those kinds of critics haven't had to BE there, working it out daily, weekly, monthly in a sea of contentious differing-opinion souls all of whom consider themselves "right." :-) I doubt (sincerely) that there's any NEED to have "a radio" modular. The 'radio" already has been a system built of modular circuit blocks for decades. All those blocks have to work together to make the "radio" work and the "radio" designer's task is to integrate those modules, make them work together. [replace "radio" with "any electronics" and the same thing is true] What seems to be operative in this thread is that some look at a PC and its very-mass production "module" pricing and the "plug-and-play" concept and sales phrase popularized by Microsoft and think it applies to all electronics. It doesn't. Those same imaginerers probably would get totally lost in trying to figure out how a "simple" plug-in card on a PC works; all such cards nowadays are little subsystems, complex, a few being little "computers" all by themselves (if using a microcontroller). They only look at the overall card specifications and THINK they "know all about it." [all they've done is to memorize some data items about the product...well after the development tasks' end] Three decades ago, radio amateurs got a taste of "radio modules" in the burgeoning use of handheld transceivers. A single Tx-Rx that could be held in one hand, complete with antenna. A full radio. (first done about 1940 for the U.S. Army and dubbed "the handie-talkie") One "module." A stand-alone communications tool. "Integration" of that module didn't need other electronics. Now with Software-Defined Radios, non-thinkers want to make those like the millions of cheap personal computers. Most don't know the basics of either receiving or transmitting radio signals or how to handle modulation, yet they want to talk AS IF they did. :-) [more righteous indignation by some readers here as they chafe at the bit wanting to vent against the statement above...heh heh] SDR is a terrible problem for the FCC in its task of regulating technical characteristics of civil radios...and will be for all other radio regulating agencies internationally in the immediate future. A very different problem. The thing is that SDR is ALREADY HERE and has been for decades...BEFORE the advent of the micro- processor and microcontroller. [that's a whole new area of discussion whose birth might have been in the transition of the regnerative receiver with audio amplifier into Ed Armstrong's "super- heterodyne" right after World War One] That the modern "radios" use "software" (actually digital control signals) instead of hard-wired manual control operation lines doesn't matter to the "radio's" circuit blocks. Those circuit blocks still have to be integrated to make the whole "radio" system. Their theory of operation has NOT changed. -- Former professional electron wrangler.

Roy Lewallen, W7EL I don't know about the 'caustic comment', but I believe the OP has a serious lack of understanding about both manufacturing and marketing. The radios we use today are extremely complex and sophisticated. Keeping everything from interacting and interfering with each other inside seems to be a challenge for engineers. How much more a challenge would a radio as he suggested be? Also, from a marketing stand point, has he noticed how Kenwood and Icom connections are so very different? The manufacturers don't want users using many outside options. And what about the cost of adding all those connections for the competitors to add modules? Who gets to pay for all that? If you do get one, how do you know it won't draw too much current and burn up something else, interact with another component causing RFI, or what-have-you? If there should be progress, it should be in the software operation of these rigs. I believe there is much progress there, although in regards to the 706 line, Icom does have some room for improvement. just my opinion... Buck -- For what it's worth. |

Just go back in time on this conference a few years back. He used to send
out his nastygrams to anyone who derided his fractal antenna. He saw more enemies than Nixon! In a single day it was not unusual to see 10 threats of lawsuits against various denizens of this conference. As is my perverse nature, I reveled in tweaking him.
