program to know the value of resistance testing new server ftp

Following several e- mails on a previous post http://cx2ua.blogspot.com/2011/02/resistencias-y-su-codigo-de-colores.htm l found this program that was allegedly done by Diego Navarro is very practical to use and help the newcomers in the electronics this is the link to download: http://www.cx2ua.com.uy:8080/programas/

To receive and decode digital signals DRM "Digital Radio Mondiale" is to connect a down converter to 455 KHz.

In my case my Kenwood R-2000 Down Converter and this small band of financial transfers from 455 to a new fi of 12 kHz.

This is achieved thanks to the famous ci Philips SA602 that inside has a converting step and a step rf oscillator.

The CI said oscillator crystal is connected to 467 kHz and by mixing remove 12 kHz apart from 467 to 455 = 12 kHz.

fi This new signal of 12 kHz. sent to sound card PC for scanning and processing by appropriate software

This is my prototype board is assembled in less than 30 minutes to do the first tests of rx

The down converter circuit of 455 kHz to 12 kHz

typical arrangement of equipment for reception of DRM

If you call attention to the subject I invite you to watch web colleague Roland PY4ZBZ one of the best and most complete, with lots of information DRM and other digital modes.

Case number 1

Looking for information on the Internet for the http://hi4rkr.blogspot.com/2010/09/antenas-su-ganancia-real-en-decibelios HI4RKR Blog . html and fence surprise to find one of my articles on antennas vs. Vertical. Horizontal published in November 2008 http://cx2ua.blogspot.com/2008/11/antenas-verticales-y-horizontales.html which was copied as is.

At least I could have quoted the source as have other colleagues with whom I am deeply grateful as is the case of Editor of Digital Frequency 430 Chilean Mr. Domingo Canales CA3VQW http://frecuencia430. blogspot.com/2011/01/antena-vertical-versus-horizontal.html

thanks to all of them from now.

case 2

Here is an article copied from the old national publication magazine in its issue AC 500, where a Dante Tartaglia article discusses the principles of radio in Uruguay and focuses primarily on Cerrito Telegraph Station. The original was published here: http://cx2ua.blogspot.com/2008/06/historia-de-la-radio-en-uruguay-co-mo_04.html and this was copied here: http://radiografias.com.uy/

If not in this case something very special would have thought that the source of this article was the same magazine I have the AC N 500, but something caught my attention and was that between the images is a picture of a transmitter on a wooden table, this picture is actually not in the Telegraph Cerrito station or is in AC Magazine No. 500, but was removed from the RSGB book called "100 Years of Radio" and was put in my post just to let the reader not familiar with the equipment time had an idea of \u200b\u200bhow the transmitters were in the early days of radio.

Easily one can tell the quality difference with the photos of original article published in this blog, which if they are original from the photo of the transmitter.

In order another case where no source is cited and think that it costs nothing to be thankful.

must have a bit of initiative that I copy the title , Pego and I have Web.

Antenna Tuner

Extended and Republished Post

Why use an antenna tuner?
All antennas at a given frequency with an input impedance expressed in R + / - jX, where R is the resistance and reactance is Jx.
If the reactance is inductive + J (the antenna is too long) the sign of J is +
If the reactance is capacitive, the sign of J is -
line feeding the antenna is a transposition R + / - Jx value to a new value based on the impedance, length, and the speed factor of the power line.
With the help of the Smith chart we can see this graphically. Therefore
the antenna connector will have a value of R + / - Jx at a given frequency.
For the transmitter can transfer maximum power to the transmission line, the impedance of the transmission line must match the output impedance of the transmitter.
This impedance is normalized to a value of 50 ohms J 0, all solid state equipment.
So the purpose of an antenna tuner is an impedance matching network, is to convert the complex impedance of the transmission line R + / - Jx a standard impedance of 50 ohms and J 0

Design

The variable capacitors are the type of transmission and must be isolated from the metal cabinet or chassis.
ideal is to use the best equipment possible but it all depends on each particular budget and working conditions shall be submitted to the ATU.
Welds shall be for a personal recommendation to "strong" is cheap tin rf transistors and not really even though we do not use more 100 or 200 watts in the continuous use this unit can be coupled loads varied from about 5 ohm about what it means to a high impedance to RF current environment and over the 800 ohm, the highest measured value for me, what means that according to the impedance that we can merge it high current or high voltage rf in rf in the derivations of the coil or band change key.
That and better working experience and a good welder welding power savings are not adequate and that more expensive then paying for any failure.
the varying capacities and inductance coils or vary according to the material with each, for the adjustment is to use a parser antenna or a good quality wattmeter between the transmitter and antenna tuner with 5 watts or less enough to have some indication on the wattmeter and with the help of an alligator clip to start band by band and always tweaking the settings C1 and C2 to find the point of the coil in which we have zero reflected power at that point we can make a referral to the key bands "the ideal would be a coil variable

The coil can be variable or fixed in which case we will draw every 2 turns leads to a key porcelain silver plated contacts, eye that produce voltages and currents of very high rf power and impedance according to we are attaching, which can damage the end of RF transistors.
So to find the best materials for our project, in terms of the variable capacitors do not recommend the use of capacitor typical old radio reception to valves, better to spend a bit of a good pair of variable capacitors for transmission.

Diagram Of Parts Of A Sunfish

If you go to the Web RU CQ Ham you can you take more than one circuit.

Searching google tranceiver circuit a repair, including the addresses was that of cq ham ru decided to go to to download the circuit and it seems is not a site not advisable to enter it will be that these children of the former USSR lost no tricks?

As soon into the site is activated the security on my PC to a port scan.

In a control in the log of my server I found that attempted to perform a sequence commands all failed, to which the server returned a 404.

The image you can see the attacker IP and the different scripts that attempts to reach the PHP administrator which were all failed.

So was looking for information on the registration data in the log.

And you query the WHOIS and this is what I found.

consultation at various forums on the topic here's one answer:

words, the attacker tries to upload a file via a remote php php programming failure, and this file attempts to download an IRC-bot which connects to a private IRC server, from where they receive instructions from the attacker, such as "scanning the network" or "attacks this server

is up to each service using the Web, but remember that certain something try them out or rather "put them in more" to change the circuit that users seek.
