If an activity is to have value it must have INVESTMENT.


Hi Dave,

Thanks for the replies, I surely didn't mean to get a flamewar going, but,
it seems there are some very
strong views on this.

I don't mind putting an investment into something...usually when I learn
something new, I research and get
into it 110%. The trouble with the requirements and all there that I see
is, that it puts up a very high
initial investment before you can actually get in and do anything with it.
I guess I question, well how do I
know it will be worth all the time invested before I even get to 'play'?

In my case, and I'm sure many others out there in this day in age, my TIME
is what is of such short supply. I
have no problem laying out cash for equipment...with most things I do, I
generally jump in with both feet,
buy equipment and 'learn as I go'. I'd like to do the same with ham and
other radio technologies, but, in
this case, I find a large wall in front of me of study and test taking,
before I even get to jump on the air
even once to see how much I'd like it.

Does that make sense to you?

Thanks for the replies,


The time investment is not as much as it seems. That is even more true of
someone who has experience in related fields or has experience in the art of
studying. For those with some existing experience in related fields, they
can often read up enough in a single weekend to pass the Technician written.
This will let you get your feet wet in the VHF/UHF and higher frequencies.
There's quite a lot that can be done in this area if you invest in the
equipment.

Again if you have some related background, the General written is not
particularly time consuming to study for either. The code is only as hard
as you make it by fighting yourself. If you decide that you will learn it,
the average person only needs about 30 hours to get to 5wpm, assuming that a
good training method is used.

Getting the General license gives you all modes and all bands and the
maximum power privileges. The only thing you do not get are some
subsections on some of the bands that are reserved for Extra licensees.

Now the Extra test is quite a bit more difficult but is not required unless
you want to get into those subsections mentioned above.

You spoke of "learning as you go". Basically ham radio is the same. Even
the Extra class license has only scratched the surface of all that might be
involved in amateur radio. The tests & licensing are to insure that you
know enough not to get hurt, not to cause harm to other people, and not to
make a mess on the bands. Also they are to insure that you have a grounding
in the basics so you don't go spinning your wheels trying to get things
working.

You might ask why this is important. Let's just address the safety area for
a moment. Well for example, you can actually get a burn from grabbing an
antenna that is being used to transmit. If you get into microwave
transmissions, you could fry your eyes (or somebody else's) if you look into
the end of a wave guide while it's being used to transmit. You can get
electrical shocks from feedback due to a poorly set up station. This is
just a small sample of some of the things that you should be familiar with.

All you have to do (if you've got about 8 hours to spare) is go

DejaNews several years ago. "Robitussin" has thousands of

especially his self-promotion as heroic USMC veteran which
he has never, ever proved through any third-party references,
digitized documents, or much of anything else other than his
own AOL home page and self-description on QRZ.

He is clearly into his own fantasy of imagined superpowers
without the aid of Stan Lee.

:-)

There's some real gems in there.

Lawsuits. Robeson sues people, or at least he says he does. In his
last lawsuit, he got an Upper Peninsula attorney gratis, then made
comments on who his free attorney's wife might be sleeping with.
Meanwhile, the person he is suing has yet to be served.

acrualywaiti ng now for 5 different lawsuits from steve


Five??? What are they for?


one was fr reporting him the BoN another for Daring to mention is
daughter (the one with dat 28dec) one forcontacting CAP, another
daring to make a true stament about his daugter last month, another
for asking if his wfe was fireproof to project her from Robeson
flaming pants


"Bricks through windows, slashed tires, terrorized wives." These are
bad things that happen to people who shoot their mouths off, as some
people have been told they do. Mind you, Robesin isn't the one
throwing bricks, slashing tires, or terrorizing wives. "Other
people" do this sort of stuff.

his other selves perhaps


I wonder if they've all manifested themselves on RRAP, or if there are
others for situations at work, at home, on vacation, when in CAP
uniform....


most likely

he must have some persona that is not the asshole stev is , since he
does go out in the world and hasn't been mrudered yet

"Dialing..." On Robesin's personal authority as a male nurse and
failed Marine, he can make a phone call anywhere in the USA and have
you picked up on his say so. Really.

yep whow much safer we are for him


Mmmmm. I don't think it works that way. Now if it were a reverse
911....


indeed

"PUTZ, Putz, putz" Disagree with Robesin and you are a penis with a
yiddish accent.

and then he dinies he makes sexauly based insults


Anyone whose read his posts for 5 minutes knows that's a lie.


not true sometime it takes more than 5minutes of reading to make
obvious after all you must first decided if he is serious

"PEDOPHILE, Pedophile, pedophile" If you disagree with Robesin and
you give of your time to a youth group, you are a pervert.

or just breath air (witness Tood Hans and Myself)

"HOMO, Homo, homo" Disagree with Robesin and you are queer, with
lots and lots of inuendo.


that is you todd Han and scores of others


Everybody's gay.


except Steve of course and all these gay men wantsteve's body (not)
same sort of insanity as wismen


Robesin is a national hero, taking part in seven hostile actions as a
Marine. Yet, his only overseas assignment is Okinawa. Never been
injured, but discharged after only 18 years. Says he's retired.
Says he's disabled. Says it's not medical. Says he has been
rehabilitated by the VA. "Ask the VA."

well I he=ard the army in wirtiing today They afrim the existance of
my old unit


Robesin has given so many mixed messages over the conditions of his
"discharge" that no one be;lieves him any longer.


indeed

Robesin got back into uniform as a Tennessee State Guard "officer" of
some kind. Very short lived career.

maybe that gruop held him to professional stanards unlike CAP


Yikes!!!


that would explain things

Robesin got back into uniform as a Civil Air Patrol (CAP) "officer"
of some kind. Says he's a Major now. Photo of him in a sage green
(not blue) flight suit on his QRZ website. As far as I know, most
CAP volunteers are involved in training youth/Cadets. Hmmmm?

I know that does worry me too


Naw. It's everybody else you have to worry about.


exactly sorry if I was unclear

Robesin got a vanity call, K4CAP, while in the CAP. The CAP HQ is at
Maxwell AFB in Montgomery, Alabama. Then he gave it up. Look where
his old call now resides.

Robesin got back into uniform as a male nurse. Says he doesn't wear
the white dress uniform. Probably just regular pants and a v-neck
lavendar colo[u]red top.

Robesin has military medals. He has lots of medals. Many of those
medals he didn't earn.

has he ever listed them?


Nope. I'd only be interested in the ones he earned. But that would
just raise more questions about seven hostile actions.


I assume the good conuct is not amoug them

Robesin used to be an ASSISTANT NCOIC of NMC MARS on Okinawa.
Doesn't know the first thing about it. Doesn't know what a MOD is.

"MARS IS Amateur Radio" according to Robesin Yup, you heard it
here first.

A well know amateur radio outlet had the owners daughter's photo
featured in a prominent amateur radio publication. Robesin said she
was selling "Something" but it wasn't radios. He's a swell guy.

Robesin can make comments all day long about how your children won't
respect you. His child died from severe birth defects and he knows
that no one will make comments about his children. He's a swell guy.

Robesin needs to talk to the wives. He needs to talk to Len's wife.
He needs to talk to my wife. He needs to talk to Mark's wife. He
wants to talk to them on the phone or in person. He wants to mail
them. He wants to knock on my door to talk to my wife and posts
partial addresses so you know to expect a visit. Now he makes jokes
about Len and Mark's wife. He's a swell guy.

I could go on, but I don't have 8 hours as Len suggests...

So what's the real beef??? I disagreed with Robesin. He doesn't
like the way I think.

prehaps it was he disliked that you THINK at all


I'm not a Morse bot.

exactly and only bots like himself are welcome

So what's the real, Real beef? I don't think the Morse Code exam
should be retained for an HF license in amateur radio.

me neither

looks liek we will win


With the tons and tons of sour grapes from these Morse Forever folks,
no one has won anything.

DX simply means distance. If you are talking about HF transmissions, it
normally refers to countries outside your own. If you are talking about VHF
and higher, it can be within your own country but at distances beyond line
of site communications.

The "DX community" is simply a term that refers collectively to those who
are particularly interested and involved in the longer distance radio
contacts.

I would like to add that DXing isn't limited to chasing awards. Some people
just like to find someone in a foreign country to ragchew with. One day I
was lucky enough to come across a gentleman in Italy who simply wanted to
talk not run a pileup. We spent about 1/2 an hour just chatting.

Example.

A few months ago a group of ham radio operators went into the central
Pacific Ocean to an island named Swain's Island [ATOLL]. Swain's Island
had just been approved by the Ham radio Certificate Powers {American Radio
relay League] as a separate DX [distance] entity and as such it qualifies
as an entry into the various DX awards [DXCC being the prime award}. [DXCC
means you have submitted written proof of confirmed contacts with other
ham radio operators in 100 or more other countries [or entities].

The Hams operated from this rare location for about a week and then
returned home. There is no-one there today!

Let me digress into another of your questions: i.e. What is SSB?

Fifty years ago ham radio, and still today the AM broadcast band,
transmitted three components to put a signal on the air. First, was the
carrier that set the dial frequency e.g. 3950 KHz. The carrier contains NO
information, it just sets the dial frequency. Then voice audio was added
to the carrier. This addition [modulation] produced two audio signals
around the carrier. One above the carrier, the other below the carrier.
So, the resulting signal had the carrier and one upper side band and one
lower sideband. The carrier contained 2X the power of the audio. And the
audio was redundant with 1/2 the audio power in each sideband. The
resulting signal can be described as Double Sideband Plus Carrier.

In the 50s and early 60s design techniques were incorporated to suppress
the carrier, which contained NO information; and to eliminate one of the
redundant sidebands. The resulting signal is Single Sideband [one audio
channel] with suppressed carrier. [SSB = Single Side Band]

Well, let me ask, from the point of view of a potential noob to the hobby. What use is the code requirements?


The 'use' is something you just can't understand. The 'use' is a commitment of
time and talent which adds value to the license. The 'use' is investment.


The term "investment" is very misleading. To explain my position, I am
in agreement that CW testing should go the way of the dinosaurs. I
have no problem with technical testing, as a way to ensure that
potential Hams can operate their radios properly, without causing
interference with neighbors and other Hams world wide. There is also a
safety factor, with transmitters that can kick out a LOT of
potentially dangerous power. So, technical exam = good idea.
Here in Canada, CW is not required IF you achieve at least 80% on your
technical exam. You need at least 55% WITH CW.
http://strategis.ic.gc.ca/epic/inter.../sf08435e.html
This seems fair, to me.

As for the "investment", not all investments are valuable. I invested
years of training to be a fully qualified mechanic. There is
considerable value in that investment, obviously, as it is my bread
and butter.

But, would my investment be more valuable if, for example, if an
additional year of carpentry training were required for me to be
certified? I mean, after all, cars had wood frames and bodies at one
time so a mechanic would have needed carpentry skills...back in the
1930's. Such an investment would be a bad one. The skills would have
no value and do nothing to enhance my skills as a mechanic. The extra
investment would have no return with regards to being a mechanic.
Carpentry would not make me a better mechanic and would not prove to
the world that I really wanted to be a mechanic.

CW is as useful to todays Hams as carpentry is to a mechanic. A good
thing to learn, and potentially useful, but should not be a barrier.

But then again, a mechanic *might* need to do urgent bodywork on an
1930's wood-bodied ambulance and therefore save somebodys life. ;-)
{hehe...sorry..just had to pour on more coal..}
Just about as likely a scenario as CW being the only way to save a
life.

But then, if I were stranded on a desert island and found some old war
time aircraft wreckage, I could modify a magneto to be a spark
generator and spark out an S.O.S. My mechanical skills help me there.

Well......could happen!!

I'm not sure I recall all the other posters idea of investment - but
"mine" - was referring to the time/cost how ever little - "spent" or
"Invested" - if you will - in the way of time to study or prepare for the
exam - acquire equipment AND to actually go on the air to make use of it.
So - yes it "can" be looked as an investment - even if in a "minimal" sense
of the word.

IN the way I "think" you're referring to - as an investment towards a
"rewarding career" or leap forward into life - eh - depends on the person.
Many do NOT make electronics their lifes work. BUT, many have started from
ham (some from CB and then ham) and went on into some electronics or
electrical field. So for "them" - it "was" an investment of sorts - into
their future.

Just like another part of this thread where "memory and memorization" was
being used, hacked, slanged - the word "investment" could also go that
direction. It is all in how you want to look at it and perceive it.

Just my 2 cents!

As long a 'Rare DX' uses CW, CW will live and thrive in the DX community.

A DX pile of 100 stations on CW occupies much less bandwidth than 1 SSB station.
The CW contact rate exceeds the SSB rate.

As long a 'Rare DX' uses CW, CW will live and thrive in the DX community.


Hey, "Dave," since when does the FCC mandate all hams MUST
"work DX?" [try to remember that "the DX community" does NOT
issue/grant/authorize amateur radio licenses, only the FCC]

"Working DX on HF with CW" is an OPTION, not a requirement.

In fact, the FCC doesn't even mandate 'working' a foreign
radio amateur at all. ['foreign' meaning any country outside
USA jurisdiction]

It's your choice: if you want to play the DX game learn the rules including 25
wpm CW.


"Dave," you really need to be reminded that the FCC does NOT
mandate/require/encourage ANY "DX contacts." Neither does the
"DX community" grant any licenses OR make any "rules" that ALL
US radio amateurs must follow.

Oh, and "Dave," the REAL US amateur radio regulations require
passing a FIVE WORD PER MINUTE (equivalent) manual telegraphy
test (15 words per minute with the "farnesworth" approved
equivalent rate), not "twenty-five words per minute."

"Dave," have you been licensed a long time? I don't recall ANY
FCC requlations requiring a "twenty-five" rating, only the OLD
regulation (prior to mid-2000) and that only for Extra class.
I'd say you really ought to review the latest rules that apply
in this new millennium. You can review those for free at the
United States Government Printing Office website under "Code
of Federal Regulations." You can also get it at the ARRL
website since the ARRL seems to think they are the only
"official" source for everything amateur...

If you want to operate an appliance, but an appliance.


You mean EVERYONE "following the rules of the DX Community"
uses homebuilt radios? All have built their own keys so
that they don't use appliance keys? Amazing...

How does anyone "but an appliance?" :-)

The time investment is not as much as it seems.


Dee, the "time investment" for MORSEMANSHIP depends entirely
on the psycho-acoustical aptitudes of the learner. "Learning"
a psycho-acoustic skill is NOT an intellectual one, it is a
physical one.

That is even more true of
someone who has experience in related fields or has experience in the art of
studying. For those with some existing experience in related fields, they
can often read up enough in a single weekend to pass the Technician written.


You morsepersons need to get a common story. The rabid morsemen
keep saying it is all "memorization," taking no skill whatsoever.

This will let you get your feet wet in the VHF/UHF and higher frequencies.
There's quite a lot that can be done in this area if you invest in the
equipment.


Come right out and say it...you morsepersons consider the
frequency world above 30 MHz to be beneath you, a place for
kids and lids (and probably space cadets) to go and PLAY.

Again if you have some related background, the General written is not
particularly time consuming to study for either.


Everyone can just "memorize" the answers, right? :-)

The code is only as hard
as you make it by fighting yourself. If you decide that you will learn it,
the average person only needs about 30 hours to get to 5wpm, assuming that a
good training method is used.


The ARRL VEC uses the "farnesworth" method which send at FIFTEEN
words per minute...even though the FCC regulations have five.

Dee, you haven't addressed the subject of the existance of the
manual morse code test itself. You (erroneously) think that it
is "necessary," possibly because you had to take that test.

Getting the General license gives you all modes and all bands and the
maximum power privileges. The only thing you do not get are some
subsections on some of the bands that are reserved for Extra licensees.

Now the Extra test is quite a bit more difficult but is not required unless
you want to get into those subsections mentioned above.


Extra class are the "elite." Having an extra license allows all
the preening and self-righteous attitudes possible in a hobby
activity. It is personally rewarding to elitist-wannabes who
have to be "better than ordinary persons."

You spoke of "learning as you go". Basically ham radio is the same. Even
the Extra class license has only scratched the surface of all that might be
involved in amateur radio.


Really? All those extras in here seem to think they are FAR
better than any professionals in radio...because they had to
test for morsemanship.

The tests & licensing are to insure that you
know enough not to get hurt, not to cause harm to other people, and not to
make a mess on the bands. Also they are to insure that you have a grounding
in the basics so you don't go spinning your wheels trying to get things
working.


Golleee! All along I thought the FCC just regulated (and
mitigated interference) in ALL US civil radio. Their
predecessor agencies (before 1934) used Licensing and Testing
for same as a REGULATORY tool. I didn't know that those were
also academic tests and diplomas...

You might ask why this is important.


Why IS morsemanship so important?


Let's just address the safety area for a moment.


FCC amateur radio regulations cover only the radiated
RF power field. As a safety issue for ALL affected by
that RF field. Does YOUR station obey the federal
regulations?

Well for example, you can actually get a burn from grabbing an
antenna that is being used to transmit.


Why would anyone do that? [anything in official rules on that?]

If you get into microwave
transmissions, you could fry your eyes (or somebody else's) if you look into
the end of a wave guide while it's being used to transmit.


Why would anyone do that? You can get far worse damage to the
eyes looking into a laser beam of much less power...and you
don't need any license for that.

You can get
electrical shocks from feedback due to a poorly set up station. This is
just a small sample of some of the things that you should be familiar with.


Those aren't covered in FCC regulations, are they?

"Feedback gives one shocks?" I suppose...I've made feedback
networks for years and never been "electrically shocked" by
them. Delighted and surprised that they worked so well,
perhaps, but never got any electrical shocks from feedback.
I guess I'm just not "amateur" enough...hi hi :-)

Let me digress into another of your questions: i.e. What is SSB?

Fifty years ago ham radio, and still today the AM broadcast band, transmitted
three components to put a signal on the air. First, was the carrier that set the
dial frequency e.g. 3950 KHz. The carrier contains NO information, it just sets
the dial frequency. Then voice audio was added to the carrier. This addition
[modulation] produced two audio signals around the carrier. One above the
carrier, the other below the carrier. So, the resulting signal had the carrier
and one upper side band and one lower sideband. The carrier contained 2X the
power of the audio. And the audio was redundant with 1/2 the audio power in each
sideband. The resulting signal can be described as Double Sideband Plus Carrier.

In the 50s and early 60s design techniques were incorporated to suppress the
carrier, which contained NO information; and to eliminate one of the redundant
sidebands. The resulting signal is Single Sideband [one audio channel] with
suppressed carrier. [SSB = Single Side Band]


"Dave," your knowledge of Single Sideband is ferklempt.

The spectra of an amplitude modulated signal was mathematically
described by John R. Carson of AT&T before the 1920s. SSB,
including suppressed carrier, was USED by the telephone
infrastructure in the 1920s for long-distance lines. The most
common system, "C Carrier," had four separate 3 KHz voice
channels and would operate on the open-wire telephone lines
then common all over the world. This "C Carrier" was directly
adapted to HF radio in the early 1930s, the frequency-multiplexed
total signal converted to HF and amplified. The first HF SSB
radio link was put into service between the Netherlands and the
Netherlands Antilles carrying four voice channels or (to become
the later commercial-military standard of two voice and six to
eight TTY channels). While single-channel SSB was experimented
with before WW2, it didn't expand until after WW2 and a number
of US military contracts awarded to then-prominent radio makers
(Collins, RCA as two examples). Based on that success, the
amateurs took it up in the 1950s while the ARRL promoted the
false idea that "SSB was pioneered by radio amateurs."

Technically, your statement was faulty. Each "sideband" (the
spectra adjacent to the carrier) carries ONE QUARTER of the
total RF power output of single-channel SSB, not "half" in
normal AM. In normal AM the carrier is always constant in
amplitude. In normal AM receivers the "detector" stage is a
mixer, combining the carrier with the two sideband spectra
with the output lowpass filtered to yield the original audio
signal. Single-channel SSB usually suppresses the carrier
(almost to extinction) and the "detector" stage being fed an
equivalent constant-amplitude carrier signal from an internal
receiver oscillator. The mix products of carrier re-insertion
and the input single sideband spectra yield the original audio
modulation after lowpass filtering.

The important thing about single-channel SSB is that a
transmitter peak power output of RF need only be one-half
to on-quarter of a conventional AM transmitter to yield
the same demodulated audio signal level.

No morsemanship skill is necessary to use a single-channel
SSB radio. Today it is being used on the open sea by
both commercial and private boat/ship owners for voice
communications; also data, separate or multiplexed, for
written communications.
