No, although it would be a nice and simple way. If accuracy is important you
should also measure the frequency at which the dip for the L/C circuit occurs
(e.g. frequency counter or a general coverage receiver w/ digital dail).
You can also build a L/C tuned oscillator with a know amount of C. Install
a L, measure the frequency (see above) and calculate the value of L.
In either case the formula is L = (25330.3) / (F^2 x C)

Subject: re: keyers and Uncle ALbert
Brad,
I tend to agree with you...It is interesting that a majority of construction
articles that appear in QST and the handbook these days require you to buy
the key component from the author, usually a programmed part. There was a
time that QST ran construction articles that used parts that could only be foundin the author's junk box...in the 70's they went a little more generic so a
majority of the parts in a project could be picked up at R.S.. I think QST
should require that authors make all the information required to build a projectavailable for free to it readers who pay $30 a year for the privilege of being amember and make the purchase of pre programmed parts an option instead of a
requirement. Otherwise, as you suggested, the authors should be paying for an
ad to sell their products.
One of the classic examples is the Super Cmos II keyer...It was featured in an
article in QST and is inthe HANdbook...but you can't build one unless you but a
preprogrammed part from the author or his representatives. Why isn't the source
code in the handbook? I feel if the article was published in QST or any other
magazine it becomes the property of the readers who purchased that magazine.
So there! 73, Brian AE9K

Well, the last time rec.radio.amateur.misc spun around and around and around
on this topic, the arguments sort of went
con: what's the point of a microcontroller demonstration article if you learn
nothing about microcontroller from it? (The first CMOS keyer article in
QST, as I recall, started out claiming that it would explain embedded
micros and then just showed how to wire up their kit.)
pro: what's the difference between an article about a
68HC11-programmed-by-Joe-Ham keyer and a Curtis 8044ABM keyer?
con: Curtis didn't claim to be teaching logic design.
con: Curtis will probably still be making 8044ABMs next year.
con: ...
pro: Coders deserve to be compensated for their work!
I sorta come down on the "it's just a kit" side, but rather than getting
exercised about it, what I'd really like to do is create some useful uC gadget
for publication in QST and make a point of making code available (perhaps a
companion QEX article about software design?). A disadvantage, however, is
that the usual kitting places might not carry it (since *I* don't particularly
want to get into the kit business) since the availability of the code would
make instant duplication easy.
Maybe what's really needed is a series of articles on designing new software
for the CMOS-II Keyer and the other black-box uC kits that have been published.

Software is an interesting beast. In the case of the articles in QST where the
authors have chosen to keep their "property" secret. As a software engineer I
like to keep control of my creations, but it would be nice too see how things
are done, such as the DSP articles.

Subject: QST COnstruction Articles
Ed PArish hit it right on the head...I think the authors are writing articles
to promote their products in QST instead of using it a Journal for sharing
ideas among the Ham radio community and fellow members of the league.
All were really asking Jim, is that we have the opportunity to complete the
project with the information presented in the article. It is pretty
frustrating to get all pumped up over an article and then find that I have to
shell out another $50 bucks to buy a key component from an author, who has grossly marked up a component's price (single source, yet) to complete it. Have you ever tried ordering parts from some of these authors? If your lucky enough to
actually get the parts after your check is cashed its usually after long delays because some private individual, the author, wasn't prepared to handle the
avalanche of orders he got.
Would QST publish a transmitter and receiver article
and not put values on the caps and resistors at the request of the author
inorder to force the reader to buy the authors kit. Thats they way I and
apparently many of the others on this net feel about not having the source code available for the projects in QST.
I would also strongly recommend that QST re evaluate it's comment about the
tiny number of readers who want to program their own roms. I think there are
more than they might realize.
I have no problem with the author providing the service of
selling a pre programmed part for those who wish to buy one. But don`t force
use to do it in order to finish a project that appearred in a magazine that
is supposed to be a membership service.

Subject: QST COnstruction Articles
**** TIMEOUT ****
While this discussion about QST construction articles and source code is
interesting to me, it has nothing to do with QRP, except to the extent that
we are disproportionally more apt to be homebrewers/kitbuilders.
I'll resist the temptation to fan the fire by injecting my own views on
this subject, or perhaps I will mail them directly to the active
participants of the discussion.
Let's try to keep focus here...asking opinions about or availability of
keyers is relevant enough, but a flame war on QST construction article
policy isn't.
Thanks,

Just thought I'd put my proverbial two cents in here.
I'm not familiar with the MFJ animal, so I'll not aim any criticism at
that antenna in particular. On the other hand, one needs to bear in mind that,
by definition, the most efficient antenna is one whose characteristic impedance is equal to its radiation resistance. Such an *ideal* antenna would have a q
of 1. Clearly a high-q antenna has to represent the exact opposite of the ideal.

I'm getting tired of saying this but I guess it need to be said every
few months. Bob, et al, I have subscribed to this mail list only to
read about the wonderful world of QRP. These ongoing posts about
non-QRP related items are boring and costly; this is not USENET but
a very private email list with a very narrow scope. Don't you realize
that some folks on here have to pay a fee for each email they receive?
You are costing them money that they didn't intend having to spend by
posting articles outside the purpose of the net (so the ``tough - they
don't have to read it'' attitude doesn't apply here). Please, stick
to the topic of the net. Thanks guys (and gals, too!)

*** Here I have to disagree. Yes, its true that most hams are not interested
in building. But those who _are_ ( and after all, it's the builders that
such articles are written for ) should be well capable of learning the
simple coding techniques required for something like a code keyer. It just
ain't rocket science. Of course, my view may be jaded, since I've been
banging out embedded firmware for a living for the past 13 years, but
I've known several ham experimenter types who've done their own little
microcontroller applications, and it seems to be a relatively accessible
area for someone who's already into electronics.
Also, I would submit that the _software_ is the ``fun part'' of such
projects. Don't know about you guys, but I find wiring up computer
circuitry deadly dull. Never one wire, always 8, or 16, or 32 or....
But when you get into the source code, things liven up. Want a new
feature? Add a couple of lines of code for it! Take out something
you don't like? Ditto! Customize the buttons for the contest on
Saturday? Noooo problem! Stick your own call into the thing for
automatic ID? Ditto! Simple software is a tinkerer's dream.
That project where the author offered source and tools for $27,
That's pretty good; I have nothing against that. It's the
ones where they sell you just a programmed part that I don't
like. Not that there's anything immoral about it, it's just
not much fun. Here you are, going to all the trouble to get
all these parts together, build a case, stuff the board;
this pre-programmed part comes in the mail, and *bingo*
