- Nothing is simple. It's a question of how far "down" you go before you
- ignore the next layer (and all it's complexity) and pretend you have
- an understanding of the entire system. When you get to that point (or
- allow yourself to accept that you can't possibly understand EVERYTHING)
- you walk away feeling fat, dumb, happy, warm and fuzzy. This is NOT a flame.
-
- Even if you communicate using only simple, home-brew CW "systems", you
- have probably chosen to ignore the next layer: the entirely complex
- and mathematical field of electromagnetic wave radiation. Ever
- take a college level course in electromagnetic fields? You probably
- wouldn't enjoy it. I didn't.
-
- People feel comfortable with what they know. What they don't know
- scares them. As a radio amateur, you probably stopped worrying about
- what was happening after the signal left your antenna (other than basic
- band conditions and RF propogation). You accepted that RF waves somehow
- traveled to their destination and that was that.
-
- As digital modulation techniques advance (this is MSEE or PhD stuff),
- radio users (and radio amateurs) will have to accept the fact that
- they cannot understand every last aspect of modulation techniques
- and move up to the next level: what do we do with the data once
- that lower layer (that we do not entirely understand) has given it to
- us? This is where the radio merges with the computer and you can
- start talking about networking, files, user interfaces, multimedia
- data transfer and the like.
-
- Even today, most radio amateurs have only a block-diagram understanding
- (if that!) of radio receivers and transmitters. Even the components of
- CW transmitters are ignored. Do you really understand the physics behind
- a transistor?? I don't. Not really. And I don't care. I read the specs
- and apply them. I don't care how or why they do what they do (more or
- less). What IS important is that they perform as advertised when properly
- applied.
-
- It's kind if like when IC's came along and started eliminating
- discrete components (transistors, diodes, resistors) in many
- digital applications. Then came the microprocessor and things
- really started moving. Then ASICS and hybrids. And on and on.
- Ever greater scales of integration. Hardware was even replaced
- by (gasp) software!
-
- I feel radio will soon see the same revolution that computers
- went through when Intel first released the microprocessor.
- We now have dedicated DSP processors and pretty cool development
- tools for applying DSP to unique applications. In radio, digital
- signal processing will take over more and more of the IF filtering
- and VFO access. We will also see more digital wide-band data via RF
- rather than narrow band analog.
-
- It's all very confusing to those who, for whatever reason, are not
- keeping up. My point is that the average user does not have to.
- Amateur radio, on the other hand, has always had at least SOME
- grasp of the technology behind it all. It is my belief that as
- commercial RF advances, we should at least be a bit more cognizant
- of what they are doing (if only at the black-box level) and why they
- are doing it.
-
- How many people in technical disciplines who ignored the computer
- revolution are still employed today? I submit the same will soon
- happen to radio communication. Except rather than losing your job,
- you'll lose your spectrum.

-
- I know what you mean. I still prefer to drive a car with a
- standard transmission and change my own oil and spark plugs.
- Despite my own personnal feelings, technology marches on.
-
- You should read other Internet groups such as the cyberspace
- and cyberpunk groups! As I've said before, the future will
- not be concerned so much with the METHOD of moving the data
- as with the data content itself. Wait till everyone has a
- virtual reality headset with a spread spectrum link to the
- world-wide network ozone! Ever see the movie brainstorm?
- Put that together with portable RF! Awesome!! That may even
- be MY breaking point and I'll have to resort to a good ol'
- CW QSO to get back to reality!
-

-
- Well, I really don't think more efficient modulation techniques
- are going to "damage" the airwaves.

- I really enjoyed reading that! I probably will get beyond the 5 WPM
- CW someday. May even enjoy it. But for now, I'm content with my
- world of landline computer networks via coax and reliable local
- communication via packet and repeaters. And I am forever grateful to
- those radio amateurs before me who pushed for the elimination of code
- (above 30 MHz) so that I could become a part of amateur radio.
-
- 73 and have a happy field day! Guess I'll finally get to do some HF
- after all. Our club call here in Ozaukee County, Wisconsin is W9CQO.
- We alternately may be using AA9W or WI9M. Maybe I'll finally get a
- chance to talk to some of you! I promise I won't talk about theory! ;-))

- I acknowledge that listening to voice (whether AM or SSB) is
- technologically simple. Regen sets can do it, and they are
- simple. And talking is easy (far easier than typing this note
- -- what mind to hand/finger coordination I need).
-
- But we don't leave it at that. We add filters (audio or IF,
- likely both), DSP. That was part of my point -- we always
- solve irritations by adding more technology. Commercially
- we are pushed. The desire for user ease starts it, but
- eventually the base of expected technology rises. And I become
- further removed from simplicity. Now you can have your
- advanced technology and I can have my simple technology at
- the same time, but only to a point, as the parts or equipment
- I need eventually disappears. And the types of radio signals
- may (I say may) disappear, either by choice or by force. Another
- example: how many early 2m HTs are usuable today with DTMF and
- other coding on repeaters? (I'm not an authority on this, as I
- don't deal with 2meters, but I don't see any hams at my club or
- at hamfests carrying earlier HTs, so I have to wonder....sure,
- the new ones are much lighter and smaller!)
-
- Technological "improvements" keep coming and equipment more-
- or-less gets more affordable to people, but must technology
- always improve, and who is disadvantaged alone the way?
-
- >Some folks tout the "exclusivity" of CW as an advantage. Hmmph.
- >If it was simple, it wouldn't be exclusive.
- >
- >:-)
-
- I see and acknowledge your smiley. And I did not bring up the
- idea of exclusive. As for CW being simple, I was not refering
- to the ease/hardness of learning Morse Code, I was only refering
- to equipment. I acknowledge that learning CW is hard to many,
- and viewed by many as being a wasteful use of brain cells. :-)
- And receiving CW is not necessarily easy, as you need a stable
- LO capable of operating within 1000 Hz of the signal you are
- trying to receive.
-
- Chipsets certainly simplify the building of a receiver (witness
- the ease at building a DC set with NE602s, etc.), but it is a
- disguised simplicity. Disguised in how complicated those chips
- really are inside. I used the phrase "environmentally damaging"
- in my original post to refer to the hidden damages due to
- chemicals used to produced our current ICs, the increased use
- of electricity overall by "modern" life, and by the quickness
- by which older (almost new in some cases) equipment becomes
- obsolete, rendering all the energy and resources used to produce
- that equipment as wasted.
-
- Just more wondering thoughts on this thread that is really not amateur
- radio policy, so I will end this unless you wish to continue :-).
