So...was all this "phase noise" invisible way back in the
1990 time? It didn't exist?

That you didn't read the published material does not mean that the
material did not exist. The synthesizer phase noise issue was debated
well before 1990.

It is referred to in QST product reviews of ~20 years ago.

Thus the tube radio. No synthesizer. What a wunderful way around it.
Hi, hi!

It only came up when a frequency
synthesizer was incorporated? :-)

Synthesizers were in wide use prior to 1990.

Extreme wide use.

The phase noise issue
became important as synthesizer circuits became common in transceivers.

The phase noise issue became an issue with the first synthesizer
circuit.

I'll invite to read up on the subject.

Ditto.

I've provided several urls.

Ho ho!

There are numerous other sources of information on the subject. Why not
avail yourself of some of them?

Compare the transmitted noise spectra of an SG2020, Elecraft K2, and K1. Guess
where that noise comes from?

Synthesizer circuits?

R70s were made 1982-84 (approximately), so the design is at least 23
years old (1981). You frequenctly denigrate others as "behind the
times", yet the R70 is the newest/most modern piece of HF radio
equipment you mention owning. Just another example of "do as Len says,
not as Len does".

That little Icom R-70 still works fine, as advertised.

While I doubt that the receiver functions as advertised, I have no
trouble believing that it works as designed.

Ya missed the point.

Ooops!

Other designs are criticized because of age - but not the R-70. Guess why.

Schindler?

I've got one. You don't. :-)

Don't want one. If somebody gave me one, I'd sell it.

And do what with the money?

I'm sure it is quite a nice piece of equipment for the casual SWL. I'm
happy for you.

Happiness abounds in RRAP!

The only thing I "recycled" was some paper to get one in working
order. :-)

I recall you mentioning that. "Cash" wasn't it? Use of a credit card
would have muddied the waters.

I paid cash for all the parts in the Type 7....

What? No TV transformer yoke?

"Phase noise" wasn't a big buzzword then. It has a three-loop
PLL in it plus a microcontroller. Sensitivity is still good and
comparable with any contemporary HF receiver.

"Phase noise" wasn't a big buzz word in the Icom engineering and sales
bunch. Elsewhere, the use of the term was already common.

Like amongst hams.

Like with the first synthesized circuit radios???

And of course, those very first synthisized circuit radios were ham
radios!

Hi, hi!

I've yet to get close to the concept of sitting around a shack
making as many contacts as possible in a given time as any
"sport."

It's called "competition".

Nope, it's called contesting.

Best of Luck.

Skill and endurance are certainly big factors in winning any amateur
radio contest.

Somebody's half-way awake. Missed the boat ont he sport concept.

Neither is that activity "pioneering the ariwaves" nor
any sort of "training for emergencies" to reasonable-thinking
human beans.

Did you ask any? No claims for contests as pioneering the "ariwaves"
have been made. Any on-air activity which requires speedy, accurate
operation is good training for emergency situations.

Contest operation also points up the weak points in any radio station. The
contest and DX folks have pushed the need for better rigs for decades.

Where money is no object. I thought you guys were focused on
third-worlders who had to self-manufacture CW only circuits?
Wherethere is no money. Which is it?

Like chess or checkers or board games, radio contesting is
a GAME.

So are all sports. Like the Olympic GAMES...

Messing with Steve is a game. Emergency comms is no game.

MARS is NOT Amateur Radio.

There are some similarities. A good strategy, playing within the rules

Rules

RULES???

Like copying the W1AW message the day before? Hello Kelly???

Hi, hi! These guys obey no rules.

They are the elite! Rules are for the other hams.

and some luck are involved. No board games that I'm aware of require
putting up big antennas at height, putting together a radio station or
planning sleep breaks.

Why must you confine your "game" to board games???

Are road rally's played on a board?

Think car racing. Bicycle racing (Lance Armstrong wasn't riding a three-speed
with baloon tires)

Allow Bill Sohl to speak of road rally's. If you dare.

It is FAR from an ATHLETIC sport.

Not if done correctly.

Let's see....I run as exercise and also a sport. Done two marathons and more
half-marathons, ten-milers, 10Ks and 5 milers than I can recall. Mike Coslo is
a hockey player.

What sports do others participate in? ot as spectators!

Lying? Robeson leads.

You *do* sound just like him, Len. Lots of words and lots of put-downs
and lots of theory. But in terms of actual radios built on your own
time, with your own resources, from your own design....nada. Zip.
Zilch. Zero. Nothing. Not that anyone here knows about in all your
years and petabytes of posting.

If I had extra copies, I could, with a year or so off to do it, digitize
those things and put them on a website that allowed at least 100
MB user space. That includes corporate documents (public)
along with photographs.

The challenge is for *homebrew* radio projects. Not stuff done for work.

Yet most of the HEROES of amateur radio were doing their heroic work
as PROFESSIONALS!!!

Explain.

Explain again!

Not worth it, since the typical PCTA
extra "commentary" (to use a word very loosely) would be
totally derogatory.

You mean you fear reaping what you sow?

"We" only fear reaping what Steve sows. Spooky dood. Low-class
ideas.

My little text and photo memorabilia on the
ADA assignment takes 6 MB in PDF.

Did you design and build ADA on your own time, with your own resources?

Did you build the VE system on your own time, with your own resources?

YOU have REJECTED simple things like a digitized license
repro in the past.

I didn't ask for it. I had already said I'd take your word that you had one.

But you sent me*several* unsolicited emails with unknown attachments of large
size. (Ever hear of compressing a file before sending?).

How was I to know what they were? I found out later that one attachement was a
picture that contained male nudity. Not my cup of tea, so to speak.

Must have been right up Steve's foci!

You would be expected to reject anything I
present...as "credentials" or whatever real proof there is...and
there is a lot of it.

It's real simple, Len:

Pick an HF radio project that you did in your home workshop as a "hobby"
activity. Not something for work, or something you did as part of a group, but
something you dreamed up and built yourself, just for the fun of it. Not some
accessory, either - a complete receiver, transmitter or transceiver.

Put a picture and a short description on your AOL homepage, just like I did. We
don't need megabytes or a long diatribe. Just a .jpg and a short description.

My project is out there for all to see. Where's yours? Or are you too afraid of
what others will say?

Was Fesseden's projects for amateur radio? Marconi?

--

Rank, title and status?

Tsk. I lost interest in DXing in "radio sports" and the wallpaper
collection of QSLs after working at station ADA long ago.

To each his own. Why do you denigrate what others find as fun? What is
wrong with live and let live?

A federal REGULATION requiring morse code testing in order
to get an AMATEUR license to operate on HF is NOT
"live and let live."

Yes, it is.

It is not. No other AMERICAN radio service requires such.

Sure it is, Leonard. You have the same opportunity to take and pass
such an exam as I did. The REGULATION doesn't single you out. I don't
know why the term "AMATEUR license" bothers you. That's what the exam
is for--an "AMATEUR license" to operate an AMATEUR radio station on HF.

Be that as it may, you didn't bother to answer the question about you
denigrating what some radio amateurs do for fun. Why would it bother
you that someone participates in a contest? I mean, it isn't as if you
are actually involved in amateur radio.

Exactly.

Would you mind saying that just one more time for the record?

And guess what: If the code test goes away, contesting in amateur radio will
continue.

Yes. Even with Morse Code.

But what is wrong with amateur radio gaining another RTTY or SSB
contester???

Some contesters are actually *for* doing away with the code test on
the grounds that it will allegedly get more hams on HF, thereby raising their
scores by having more folks to work and making some sections/countries/zones
less rare.

73 de Jim, N2EY

And all PCTA's are actually against doing away with the code test on
the ground that it will diminish their status as "REAL Hams."
