No progress in decades...
 
Decades have brought us moon landing, mars landings,masers, lasers, lets,
fets, mosfets, computers, etc...

But the shape of radio equip. has remained virtually stagnant.

One "innovation" would be to just copy what the IBM clone has taught us.

Build a radio of "cards." Just like the computer, a standard case which you
can plugin various power supplies, frontend board "cards", intermediate
board "cards", buffer amp board "cards", IF board "cards", audio board
"cards", xmitter board "cards", final amp board "cards", etc.... I think
you get the pic

One radio case can/could virtually be any radio you can imagine.... new
design in a frontend? Plug in a new front end "card", new audio offering?
Plug in a new audio board "card."

Someone really should get off a dead duff somewhere and DO IT!!!!

Kinda makes ya wonder why not? Doesn't it?

Warmest regards,
John

I sure seem to hear that a lot.

Some *other* lazy bum oughtta get off his duff and do it.

Why don't you do it? If the problem is that you don't have the technical
know-how, well, how do you think those people who have it, got it? By
being lazy?

Typing a few sentences and hitting Send sure is easier than studying,
isn't it?

Actually, sounds a lot more like the Elecraft K2. Nothing new with the
approach. Better spent, would be the time and effort to improve the
operational performance. In-band dynamic range could stand some improvement,
and oscillator phase noise is an abomination both on RX and TX of most every
radio out there. Someone COULD, if only he would. Too busy dreaming up
defunct ideas.

This may be the answer to your dreams. A SOFTWARE DEFINED RADIO!

http://www.flex-radio.com/

This radio is basically controlled by software. Selectivity not good
enough? A new program is written and distributed (the programs are
free!)...

New band authorized? New software is written to include the new band...

A new digital mode invented? Yup, new software is written to give the
radio that capability...

John Smith May 8th 05 02:43 PM

Well, if what I see coming on the horizon is what I think it is--American
dominance in "innovation" is dying....



With China, India, etc. "coming online", even the American consumer will
soon be of small importance... even our auto manufacturers will soon be
selling more cars there, than to citizens here... as these countries
continue to "harvest our bucks" and upgrade, soon we will not even be able
to compete over the cost of oil--it will go where it is more
important--manufacturing over-seas...



Tying the hands of ourselves with overly restrictive rules and regulations
which hamper our ability to compete has been taxing too--some of these ideas
can only be instituted over-seas--where they will soon see the idea of
promoting innovation and forward progress is conductive to even their
self-serving interests...



Not everyone sees salvation in a new regulation, law or restriction…



But, we will see...



Warmest regards,

John

You can buy poison--but can't poison your neighbor... you can buy razor

Your comments are interesting. In the late 1970s and early 1980s, the
amateur market did begin down this road.

Look at: The Heathkit SB-104(A) and the Yaesu FT-ONE. there were a number
of "lessons learned" from those experiences - but the "state of the art" has
also moved from "thru-hole" construction to surface mount.

This concept is not unique to amateur radio, network equipment manufacturers
have gone back and forth between "chassis based" equipment and "appliance"
at least 5 times over past 20 years. Each has their unique attributes,
advantages and disadvantages ....

I've considered this sort of a radio before. There are a few problems,
however:

First, there is a fundamental difference between digital systems and
analog systems that prevents this sort of thing working with the success
of a PC.

The basic difference is that with a digital system you either end up
with a clean signal or a useless signal. In an analog system the
character and purity of the signal must be carefully guarded, at least
until you manage to digitize it. This means that there will be a much
greater chance that adding a new card to the radio will degrade not only
the function of the new card, but the function of all the other cards.

Second, the PC market is a huge one, with great advantages to be derived
from common equipment and software, and much smaller advantages to be
derived from commonality. This is the exact obverse of the radio
market, including homebrew radios. To make a "card" radio would be to
define a basic radio architecture, probably down to the IF frequency (or
at least to the point of forcing you to match your IF and front end).
While improvements could be made within this structure an independent
experimenter couldn't play around with such things as direct-conversion,
different IF schemes, etc., without extensive modification.

In this way the radio market is more like the market for computing
devices as a whole. The PC market doesn't account for the most
processors sold, or even the most dollars of all computing devices. The
largest segment of the market is in embedded computing devices ranging
from things as visible and obvious as your PDA, through cell phones, and
down to burglar alarms and TV remotes. Take apart a new home thermostat
or TV remote and there's a good chance that you'll find a processor that
implements most of its functionality in software -- but a very slim
chance indeed that its PC compatible!

You can get a software defined radio. Front end, and pipe it into your
computer, and there ya go! Ten Tec also manufactured the Pegasus a few
years back, close to what you are thinking of.

Personally, I don't think that the PC computer paradigm is any way to
go. It's just how PC's evolved. Despite years of progress, plug and play
is not universal, and just another PC promise.

I hope you are kidding, John. That is the absolutely worst part of the
PC paradigm. Thousands of perfectly good electronics thrown out, often
made obsolete due to software that is bloated and poorly written (mostly

The PC paradigm is a poor one, and not to be emulated. PC's will
finally be mature when we don't have to replace them on almost a yearly
basis. At that point, software writers will be able to write good software.

You might want to check out the idea of filtering. Cleans up the

I use Free Agent. It doesn't do filtering, but as I said, I turn on my
mental filter that says, "When you see a post by 'John Smith'", ignore
it. I used the same filter for "Fractenna." Works fine.

You can get a software defined radio. Front end, and pipe it into your
computer, and there ya go! Ten Tec also manufactured the Pegasus a few
years back, close to what you are thinking of.

=======================
The Ten Tec Pegasus is very much alive . It is now called Jupiter ( the
Pegasus with 'knobbed' front panel and a display and a nice enclosure like
other traditionally looking radios)

He gave the impression of being someone who'd been here before,
though at least it wasn't cross-posted to the UK newsgroup.

It just struck me as "well what's it doing here?". This newsgroup
isn't about commercial equipment, though we seem to have a slow
slide to where such things do appear here. Yet the poster seemed
to be talking about commercial equipment, and whether or not
that was the point, making your own equipment shouldn't be quite
about building a copy of something someone else built.

Had he posted in rec.radio.amateur.equipment I think perhaps
the tone of the response should be different. But here, at
the very least it should be a discussion of modularization rather
than subject header that is bound to alienate, and an expectation
of how things should be.

The talk of modularization, which seems better fitted to radio
than "plug in boards", has been discussed quite a bit over the years.
But of course, rather than some universal system (which has had
some articles in the ham magazines) the focus has been on breaking
things down to smaller portions so you can experiment, or you
can change things without having to change everything. And yes,
solid state devices, because of their small size, low price and
even function allows a better implementation. When you can
switch with DC it is much easier to do modularization than if
you have to have everything hanging off a bandswitch.

Quite agree, particularly since the "idea" was so poorly thought out to
begin with. Personally, I'd be glad to own a box that was seriously better
in performance that any current offering, even if it were spread all over
the table and housed in a cardboard box. I'd then be wishing all my
neighbors had one as well so I wouldn't be stuck with THEIR radios
shortcomings. Even be willing to buy the things for the two closest ones.

Roy Lewallen May 8th 05 08:47 PM

To make a positive posting about why the "board" receiver doesn't exist.
.. . First, I consider my PC. While my very first PC had a bunch of
cards, my current one has none except the RAM. The video adapter,
Ethernet capability, sound system, modem, serial, parallel, and USB
ports are all on a single board, built in.

Why? Simple -- it's cheaper.

I worked at Tektronix for many years. During that time, Tek made both
portable scopes and laboratory scopes, the latter having a mainframe and
plug in modules. For a given configuration with the same features, the
lab scope was always considerably more expensive than the equivalent
portable. Why? Well, the lab scope was always overdesigned for any
particular job. The bandwidth of the interface had to handle the highest
frequency plugin. The power supplies had to handle the highest current
plugins, in any combination -- enough current at 5 volts for a digital
analyzer plugin, enough higher supply voltage current for a spectrum
analyzer plugin, and so forth. There had to be enough connector pins and
supporting circuitry to handle all possible controls on all possible
plugins. No single configuration ever used more than a fraction of the
built-in mainframe capability. While the portable scope's stages could
have optimal gain, in the lab scopes, the signals always had to be
normalized to the levels specified for the interface. This often
required an extra stage or two for each of the signals being passed
(vertical, Z axis, horizontal, and many controls). Power supplies had to
be decoupled in each plugin at the interface. And finally, good quality,
reliable connectors are much more difficult to find, much more expensive
to buy than you'd think -- and even so, they can easily be the least
reliable components in the system.

Then there's the problem of trying to predict what would be developed in
the future when you design the mainframe, so you can build in the
necessary interface circuitry. And every new plugin (I've designed them)
has to be compatible with every tweak and trick used by all plugins in
the past which it might be used with.

The fact is that hams, for sure, wouldn't pay all the extra money a well
designed plug in system would cost. Of course, I might be wrong --
anyone who thinks so (one particular person comes to mind) should get
busy designing and developing one. Perhaps there's a fortune to be made.
Certainly there's a market for a much simpler plug in system with much
less versatility than the oscilloscope system I described, as a few
manufacturers have shown. The question is, how far can this be taken
before the market dries up due to the increased cost?

John Smith May 8th 05 08:56 PM

Yes, I use my filter too--and support and expect others to use them as they
see fit... I certainly do mine!!! I can help if some are having
difficulty; I support filtering and have an understanding how to apply
them...



However, the very vocal ones--I am always left wondering if they really are
remarking about filtering their own content--or their wish to filter the
content of others (and, for what purpose would they do this?)... if that
goes on too far (controlling others), yanno, it leads to attempted thought
control--a guy wrote a book about that--George Orwell... Was that in 1984,
or was that about 1984? .. anyway, if you ask me--he was more a prophet,
some have already grown to accept what he (we?) feared...

Hmmm, I thought it "right in line."

If such equip. was adopted, then just as with computers, you could
buy/cut/etch a "card" with the expectation it could be inserted right into
the bus of that radio and function, taking on responsibilities--for say an
audio amp (just as that EXACT capability exists with a computer bus)....

Indeed, this idea does NOT bypass homebrewers, it encourages them and
provides them MUCH more opportunity to participate in constructing their own
equip.... I see it as EMPOWERING homebrewers--far from the opposite!!!

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!!!

I agree, there is a "divergence" of most other devices, with radio in the

The technology of the 1920's-1930's has been bypassed--we are too late to

technology at this point--realizing--we will NOT halt those around us... in

| I've considered this sort of a radio before. There are a few problems,
| however:
|
| First, there is a fundamental difference between digital systems and
| analog systems that prevents this sort of thing working with the success
| of a PC.
|
| The basic difference is that with a digital system you either end up
| with a clean signal or a useless signal. In an analog system the
| character and purity of the signal must be carefully guarded, at least
| until you manage to digitize it. This means that there will be a much
| greater chance that adding a new card to the radio will degrade not only
| the function of the new card, but the function of all the other cards.
|
| Second, the PC market is a huge one, with great advantages to be derived
| from common equipment and software, and much smaller advantages to be
| derived from commonality. This is the exact obverse of the radio
| market, including homebrew radios. To make a "card" radio would be to
| define a basic radio architecture, probably down to the IF frequency (or
| at least to the point of forcing you to match your IF and front end).
| While improvements could be made within this structure an independent
| experimenter couldn't play around with such things as direct-conversion,
| different IF schemes, etc., without extensive modification.
|
| In this way the radio market is more like the market for computing
| devices as a whole. The PC market doesn't account for the most
| processors sold, or even the most dollars of all computing devices. The
| largest segment of the market is in embedded computing devices ranging
| from things as visible and obvious as your PDA, through cell phones, and
| down to burglar alarms and TV remotes. Take apart a new home thermostat

| implements most of its functionality in software -- but a very slim
| chance indeed that its PC compatible!

Exactly my point....

We break into two groups of thought here...

Halt at this point, and lay all plans on that halting (and, if ALL the
others don't agree--be bypassed anyway)...

Or, stay with the pack, realizing if that day ever comes (technology ceases
to innovate/obsolete)--we will regret it...

Progress, obsolete equip., is the most desirable thing I can imagine! It is
a given, not all will agree... Indeed, at 52 years of age, my place in the
"scope of the world" is becomming smaller--it only gets worse from now on--I
am not ready to quit and attempt to force others to that "quitting" with
me...

When the "Dick Tracy Wrist Radio" is finally designed and
implemented--perhaps there will be a "death of homebrewers" (I myself am NOT
much of a 'watchbuilder')--but until then we can have fun!

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.

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."

| 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.

I don't know you "Mr. Smith" or have any bone to pick with you but I use
filters to avoid what I find as either offensive or provocative.
I invoke enough cat-fights of my own on Usenet and don't need to be
drawn into others. Some posters have a tendency to attract fire, and I
have a weakness to jump in sometimes. I'd really rather just avoid it.
My sanity and blood-pressure will be the better. So, thats why I
filter out the provocateurs if I feel that strongly.

My filters don't prevent anyone from saying what they want to say. But
historically, some posters can be counted upon to say what I'd rather
not have to read and wind up being diverted from the topic or grappling
to bite my tongue, etc. Its easier just to filter them away. Call me
Ostrich-Man. Its my means of finding satisfaction with Usenet.

For my part, feel free to choose to speak. And respect my freedom to
choose whether or not to listen.

Ohhh, well, you are correct. I am rather blind to "politics" and come from
areas where new thought, conversation--indeed, even argument and debate are
encouraged and viewed as "good things."

While not attempting to invoke "havoc", "discord" and "chaos", I view the
manner in which topics are handled as being the deciding factor--foul
language, character assassinations and promoting outwardly dangerous evils
which threaten the moral fabric of society are as disgusting to me as the
next guy...

If the material is just gauged on whether it provokes debate, argument and
thought--and if the measure of this is simply how many posts are invoked as
responses--with the desirable number set as one or NONE--then further delays
in progress should be expected...

A silent discussion is beneficial to no one... and certainly don't view
such as desirable!

Warmest regards,
John
