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."

No non-amateur-licensee can possibly operate legally on Field Day? I'd

No, he's right, Dave.

FCC specifically defines the term "operate an amateur radio station". It means
to be the control oeprator, responsible for rules compliance. By definition,
only a licensed ham can do that. Others "participate in amateur radio". Len
cannot legally operate an amateur radio station, according to FCC. Nor can
Michael Powell, for that matter.


That's your interpetation of the rules and I consider it far too
literal James.


Literal interpretation not permissible.

I.E., morse code exams at 5 wpm vice anything else (Farnsworth) at
12-15wpm.

I.E., monetary compensation for making a transmission (repeater
owners).

Oh, well. So much for literalisms.

By any normal standards the individual punching the
buttons, doing the tuning and doing the communicating or in any
combination is defined as the operator.


Such as the "attendant" at a military communications switch?

The Op at Brandywine wouldn't have time for your illigitimate
complaints.

Everywhere, not just in ham
radio.


Everywhere? Even at military switches? Oh, my!

In the case of ham radio Part 97 requires that a licensed ham
has to be onsite, watching and listening if the operator does not have
a ham license.


It gets mightly lonely at those mountaintop repeater sites.

But all that is besides the point.


THAT I agree with!


Amateur regulations are besides the point?

Be sure to send that sentiment to Riley, and sign it, "Extra."

What matters most in amateur radio - or any
field of endeavor, really - is what is actually done, not what's theoretically
possible. That's the point of the story about my highschool friend who had lots
of great ideas (and lots of criticism) but no station of his own. The computer
folks have a word for it: Vaporware.


Firmware? Software controlled radios?

Is an Icom R-70 evil vaporware?

A beat-up Budbox is wholesome hardware?

I think your prejudice is showing.

Who do you have more respect for, Dave:

The person with a modest amateur station who is actually on the air making QSOs

or

The person who talks endlessly about "state of the art", "better modes and
modulations", "the future of amateur radio", "progress", etc., etc., yet who
isn't on the ham bands at all?


Windbags.


That's all quite easy to say if that person has amateur operating
priveleges. Plenty of Windbags in amatuer radio. One is attributed
with high status if they have passed a Morse Code exam. Woo Hoo!

The person without operating priveleges may yet own the best ideas and
concepts wrt HF radio. You choose to deny him or her the opportunity
advance amateur radio. Too bad for all of us because of your
inexcusable prejudice.

Meanwhile, you bootlegged as a kid. But its all "good." You're an
Extra now.

One of your continuing problems is that of telling the difference

I note your silence on gay marriage. By your silence, you must support

Lennie's "success" in "professional radio" was getting by on the

Sounds like libel.

Are you certain it's true?


I am more certain of the honesty and reliability of the person from who I

I have word that his "performance" was less than

Whatever's left of your reputation is at stake.


What's left of MY reputation will still be standing long after you have

Oh, nevermind. You're a habitual liar.


I am sure you wished it was true.

We'll discuss it at next Dayton...See you there, Brain!

More a successful con-man than

I am gald you agree.


Wherever did you get that idea?


Why, through your SILENCE, Brain! You requoted the statement and didn't
comment on it. By your own "Rules of Engagement", failure to comment on
something means you condone it by virtue of that silence. You've expressed
those very sentiments in another thread within the last 12 hours.

Again, you provide us with yet another example of not being able to keep
your OWN stories straight, Brain.

I hold my agreement in abayence. Exactly what are you gualled about?


I think you meant "gaulled".

We could start with your complete lack of character, your DOCUMENTED
pattern of lying and deceit, and we can wrap it up with your complete failure
to validate even ONE example of your self-proclaimed "superior operator"
status.

And that's just what we know of you from THIS forum. I shudder to think
what any deeper investigation might reveal.

Kills it for me.

In the ancient times, you mounted the parts on a wooden base, then wired it
up. Build a rig in an evening.


ME built a rig on a wooden base? You jest. Never in this world . . !
Aluminum or steel or forget it.


I've done it...

Point is, it was quick, inexpensive, easy and forgiving of errors


And when it's done it looks just like what it is, a POS.

Then came metal chassis and panels. Do the metal layout, the metal work,
mount
the parts, wire it up. Build a rig in a bunch of evenings.


SOP.


Yup but a lot more work than a piece o' wood


I'm willing.

Given typical basement resources, I'll have my mechanical dial built and
calibrated before the other guy has his PC boards done.


Probably but it depends on whether yer talking Collins quality or
rubber-band quality mechanicals.


I figured that one out about 35 years ago:

WW2 surplus had lots of good parts. Among the very best are the integral
dial/reduction drives/capacitors found in ARC-5 rx and tx units, and the
LM/BC-221 freqmeters. All you need are adapters for the shaft and a new dial.

Swords into plowshares. I never bothered with Millen and National drives for
serious stuff.


Then you missed the boat. As you know I'm more than just a tad
familiar with those old surplus drives. They were designed *seven
decades* ago for use in high altitude high vibration combat
environments. Usually on fixed freqs. None of which has anything to do
with ham gear particularly today's ham gear. They're miserably slow
tuning *kluges* by any realistic measure. I could build a complete DC
rcvr in the space one of those clunkers sucks up and it would have a
nice smooth tuning mechanism. Which is why you got the last of those I
had. I am not going to be the Last Dinosaur, that's your yob.

The Type 7 uses a cap from a hangar-queen BC-221. 100:1 nobacklash

drive,
thermally compensated, extremely rugged cast frame, etc. Better than almost
anything in typical ham gear. Cost maybe $5 for the whole chassis, which has
lots other good parts.

To get more dial spread, I made a dial drum from a piece of 6" plexiglass
tubing. Recycled, of course. Dial light/reflector assembly is inside the drum
and shines through the plexiglass. You view the lighted dial through a window
in the front panel.

To calibrate, I wound a piece of paper on the drum and marked it with the aid
of my working BC-221. Then the raw paper was redrawn via CADD, the result
inkjet printed on a scrap of Mylar drawing stock, and the whole thing put on
the dial drum. Works and I can read it in any light, with or without glasses.


Steam locomotives and gas lamps still work too. I'm waiting for you to
announce that you're driving back and forth to the job in a 1937 Model
72 Terraplane.

Sure he did. He had a cb set, for one.


Seems like he also had some green dot / yellow dot sorts of reddios in
addition to the CB rig. 100% Rat Shack and Moxon plug & play. Whatta
"homebrewer" . . .


You see what some folks pulled with those licenseless HTs down in Orange
County, FL?


Nope.

Yeah, I guess we had to have somebody "over there" reading the
repeater meters and locked in mortal combat with all those kamikaze
geishas in the joints in Tokyo. While I worked my way thru E school
back here on the home front. On my own dime.


Been there, done that - halfway, anyhow. One big reason I went to Penn was the
nice Benjamin Franklin scholarship they gave me. Covered more than half of the
cost per year. Also NDSL loans and a near-full-time job year 'round.


I took a different path and not only paid the full tab as I went along
via the job, I also had a nice wad in the bank and two years worth of
engineering experience at the end of my trek. No summers off though.

Junior year was a trip - 5 engineering courses and working 35-39 hours/week.


That's ugly.

No car, either. Thank you SEPTA....


PRR MU-54s: 14 minutes flat from Aldan to 30th St.

I run a LISP
rountine in Autocad to come up with the cross-sectional properties


Nice! But I prefer Microstation...


Lemmee know when you get yer home installation of Microstation to spit
out the plane and torsional moments of inertia of a tower section.

I can get that result in about 120 seconds.....


Here we go, I'm gonna hold yer feet to the fire on this one Micollis.
I'm gonna show up at your place with a .dxf of a random cross-section
on a CD and you find **all** of it's cross-sectional properties within
120 seconds or you pop for my Newtown Square Ale House wet roast beef
sammich.


All I do is email the problem to you and wait for the results. Then
Microstation does a format conversion....


You SLIME!

I didn't say I could solve the problem, just that I could get the results!

I'll buy the RB without a bet.


.. . . you got that right . . !

dial/reduction drives/capacitors found in ARC-5 rx and tx units, and the
LM/BC-221 freqmeters. All you need are adapters for the shaft and a new

dial.

Swords into plowshares. I never bothered with Millen and National drives

for
serious stuff.


Then you missed the boat.


No, I didn't.

As you know I'm more than just a tad
familiar with those old surplus drives. They were designed *seven
decades* ago for use in high altitude high vibration combat
environments.


Which makes them perfect for ham rigs.

Usually on fixed freqs. None of which has anything to do
with ham gear particularly today's ham gear. They're miserably slow
tuning *kluges* by any realistic measure.


I *like* slow tuning. How fast did you set the dial on the '847 for FD? 5 kHz
per turn?

Lookit all the "modern" HF rigs - they typically default to a tuning rate of
5-10 kHz/turn. I was doing that in my homebrew rigs 35 years ago.

The best Millen and National could do was a weenie 10:1. Miller came up with
that goofy 6:1/36:1 planetary that cost the earth and felt like mush.

A good BC-221, ARC-5 or LM cap will do the job better and for a lot less money
and grief. Real gear drive, low torque, nice dial, etc.

Was the S-line a "kluge"? Tuning rate was 20 kHz/turn, IIRC, and took the ham
bands in 200 kHz chunks. Covering 80/40/20/15 took 10 bandswitch positions and
10 xtals. Plus going across certain points on the same band (say, 3590 to 3610
or 7195 to 7205) took a bandswitch move and running the dial almost end to end.

I'll take my surplus, thank you very much.

I could build a complete DC
rcvr in the space one of those clunkers sucks up and it would have a
nice smooth tuning mechanism.


Be my guest. You can put it on a website, just like you-know-who hasn't.

Which is why you got the last of those I
had. I am not going to be the Last Dinosaur, that's your yob.


Oddly enough, ARC-5 prices keep going up but BC-221/LM prices are down.

OBTW - check out the prices on new rotary optical encoders of decent quality,
if you're thinking about a synthesized design.

Remember that you'll probably need one with a lot of slots/steps on the encoder
disk. For example, if you want to have a tuning rate of 10 kHz turn and want
the steps to be 100 Hz, you need a 100 slot/step-per-rev encoder. If you want
faster tuning rate without sacrificing resolution, you need *more* slots/steps.

How many junker BC-221s can I buy for the price of one good encoder?

The Type 7 uses a cap from a hangar-queen BC-221. 100:1 nobacklash
drive,
thermally compensated, extremely rugged cast frame, etc. Better than almost
anything in typical ham gear. Cost maybe $5 for the whole chassis, which
has
lots other good parts.

To get more dial spread, I made a dial drum from a piece of 6" plexiglass
tubing. Recycled, of course. Dial light/reflector assembly is inside the

drum
and shines through the plexiglass. You view the lighted dial through a

window
in the front panel.

To calibrate, I wound a piece of paper on the drum and marked it with the

aid
of my working BC-221. Then the raw paper was redrawn via CADD, the result
inkjet printed on a scrap of Mylar drawing stock, and the whole thing put

on
the dial drum. Works and I can read it in any light, with or without

glasses.

Steam locomotives and gas lamps still work too. I'm waiting for you to
announce that you're driving back and forth to the job in a 1937 Model
72 Terraplane.


What kind of light bulbs do most people use? Good ol' incandescents,
fundamentally the same as Tom Edison had more than 125 years ago. Biggest
changes were the use of inert gas rather than vacuum in the bulb, and tungsten
filaments. Both circa 1900.

Internal combustion engines, home construction, lots of others.

Sure he did. He had a cb set, for one.

Seems like he also had some green dot / yellow dot sorts of reddios in
addition to the CB rig. 100% Rat Shack and Moxon plug & play. Whatta
"homebrewer" . . .


You see what some folks pulled with those licenseless HTs down in Orange
County, FL?


Nope.


Coupla kids stole school HTs (dunno if they were green dot or yellow dot or
FRS/GMRS) and then said they were gonna blow up the school, shoot teachers,
etc. Both were over Len's 14 years of age limit. Both are in really deep stuff.

Sure, transmitting radios don't need licenses or training in proper use....

Yeah, I guess we had to have somebody "over there" reading the
repeater meters and locked in mortal combat with all those kamikaze
geishas in the joints in Tokyo. While I worked my way thru E school
back here on the home front. On my own dime.


Been there, done that - halfway, anyhow. One big reason I went to Penn was

the
nice Benjamin Franklin scholarship they gave me. Covered more than half of

the
cost per year. Also NDSL loans and a near-full-time job year 'round.


I took a different path and not only paid the full tab as I went along
via the job, I also had a nice wad in the bank and two years worth of
engineering experience at the end of my trek. No summers off though.


Me neither - summer and "breaks" were the time to pile on as many hours as
possible. No OT but even straight time was worth it.

Junior year was a trip - 5 engineering courses and working 35-39

hours/week.

That's ugly.

No car, either. Thank you SEPTA....


PRR MU-54s: 14 minutes flat from Aldan to 30th St.


but...but...they're OLD technology!

I run a LISP
rountine in Autocad to come up with the cross-sectional properties


Nice! But I prefer Microstation...


Lemmee know when you get yer home installation of Microstation to spit
out the plane and torsional moments of inertia of a tower section.

I can get that result in about 120 seconds.....

Here we go, I'm gonna hold yer feet to the fire on this one Micollis.
I'm gonna show up at your place with a .dxf of a random cross-section
on a CD and you find **all** of it's cross-sectional properties within
120 seconds or you pop for my Newtown Square Ale House wet roast beef
sammich.


All I do is email the problem to you and wait for the results. Then
Microstation does a format conversion....


You SLIME!


Serious spankage, huh?

I didn't say I could solve the problem, just that I could get the results!

I'll buy the RB without a bet.


. . . you got that right . . !

What's the beverage of choice with those sammiches?

73 de Jim, N2EY

......still missing the old Drexel Ale House in the Bond Shopping Center.......
