This place is dedicated
to who still conceiving radio amateur like a creative activity, of learning, experimentation
and intercomunication. I sincerely believe that the unsubstantial
chat it has occupied (in our
country) the space that formerly use to congregate
enthusiastic youths that, attracted by the communications techniques, found much more: Friendship, solidarity and
passion. On this times, when consumption society teach us the infernal art of satiating our
whishes buying any thing (among them, our radio equipment), we oppose our right to
enjoy of our creative capacity and the happiness
of understand the instruments we use...
The majority of the technical articles has been
inspired by topics of popular conversation in our country, often very
controversial, for that I believe it that it is worthwhile the effort
of to do a more exhaustive
development that facilitates their learning and/or understanding. I
hope they are useful for you...
Do promotes in your club the realization
of Knowledge Fairs to exchange books, magazines, design programs,
circuits knowledge and experiences, where you can show your work and to
learn from
others. Where you can teach something of what you know and enjoy
doing it...
My english knowledge it is not so good to
make exact translations. I am sorry for reading difficults... If you understand Spanish I suggest go
to spanish site to text comparing...
¡You can help another Hams...! If you can help me with translations I am
very pleased to credit your collaboration on the site pages.

need "symbol" font to read it correctly.
Published
originally in 1992 via on Packet Radio and awaiting being rewrited with good
images. Basic notions of astronomy for Hams. If you have imagination there
are not problems with it...
Creole
technical novelty: A novel
and interesting multiband antenna that will solve a common mounting problem.
Very practical to substitute "long wires", to rise with kites or to hide
of the neighbors...! it doesn't needs transmatch...!

NEW (preliminary,
last upgrade 2006-12-13) The Trap-Balun (an
improvement to the "Choke Balun").
Creole technical novelty:
A light monoband balun that presents bigger impedance than the popular and
efficient choke balun on working frequency
[I] NEW
(preliminary, last upgrade 2008-02-07)
The "Syringe" antenna
revised (an improvement to the "Resonant Feed Line Dipole").
An end feed half-wave monoband dipole having same
feed impedance of standard center feed dipole. Ideal to rise with kites or
to make firm on the CATV posts
An old article had published many years as
Packet bulletin. Can still be useful for those who begin today in this
modality. Use of BBS, Bulletins, Messages, etc.
The "Hambukito" project, it is an
intent of endowing us with a little book in our language that summarizes
most of the characteristic aspects of our activity. From the disappearance
of the Amateur Radio Handbook spanish translation that Arbó Editorial
carried out, our comarcs have lost a valuable reference point.
It is my intention to pick up something of that "Sacred Fire" as it called
it by my friend Ruben Andrés (LU 1CGI) and modestly try to vivify the flame.
(There is already abundant material that, although it is in revision state,
can be useful now...) More information and material in the project's page

A controversial antenna. Truth, myth or
fantasy?. had Julio Verne used it in his center of the Earth trip?. A
serious study of the antenna that Fabio Zerpa didn't cheer up to publish...
An amusing technical dialogue between the
radioaamateur and academic world, Or "About a project of a North American
University where the Argentinean Ham Radio put the tablespoon... "
An antenna that it can really be the solution
for efficient communications in low bands when there are not space neither

(Last upgrade: 2000-08-28)
Can we receive signs that are 20 dB below the noise of our receiver? Is it
possible to communicate with equivalent powers to those that it uses a
neuron?. A fascinating experience within your reach...
Also an analysis of the PSK31 (in DigiPan) in action, copying a sign -10 dB
below the noise...!!!
A very common technique that
solves many necessities of impedance matching. Simple and
effective method that also allows to understand the
principles involved in many circuits such as transmatches,
antenna hairpins and much more...!
Solving mysteries... How to
calculate inductores, solenoid and toroids. Q Calculation, distributed capacity and
effective inductance. Coils won't be a problem anymore...!
The radiation diagrams and how to
take advantage of them is something simple of understanding,
unaccountably around they spread myths that prevent to take
advantage of the best in our antennas...
A very simple explanation of operation
this exciting instrument. A new window
will open up because the document is in the Web of the Cinave
Nautical club. www.solred.com.ar/cinave).
Common applications of the
radio in this nobleman deports. It can be good to pass him the
link to some friend that navigate (for the water, not for the
Internet...) a new window will open up because the document is

Amateur radio interplanetary communications
possibilities. Use
of common equipment. Range. Possible communications with
future missions, manned or not, to Mars. To begin to
investigate...
An article that tries to fill a
hole in the amateur literature, especially those of Spanish speech. It is not for beginners, but who is interested
seriously on transmission lines and the impedances matching will find this
useful and instructive
article.
A quite exhaustive explanation of
the way in usually propagates a of VHF / UHF signal.
Demonstration of the most common formulas. More mathematical
that would be suitable in an amateur site, but
if you are one of those that want to know all the "reasons",
here you will find at least one...
