Hello friends!
Another gift from kaspersky.ru is the Kaspersky FREE antivirus. Thanks to Evgeny Valentinovich and his laboratory!
I was, I switched to chinese antivirus"360 Total Security", But then I got sick of their ads and regular freezes on full verification cars. I killed him without pity and, in search of alternatives, came across the good old "Kasperich".
Halva, guys! Why not take it? We just demolish all other antivirus programs, download, install and activate "KF".
Activation will take place only for IP users in Russia, Belarus and Ukraine, and you will receive a one-year license for the installed product.
Link to the office. the page
Direct link to, I don't know how long the link will work.
βKaspersky FREEβ works clearly and stably, doesnβt advertise anything (except for oneself-beloved) and does it very well. modestly, does not hang, does not load the car. It is simply not visible in the system.
From kosyachkov - do not plow links to the description of the found harmful objects on the Casper's Virus Encyclopedia.
Well, the grumblers are personally from me. I didn't like the "KF" interface. Well, I don't like all these newfangled programming interfaces to work with one fucking finger and one gyrus. All right, tablets with telephones. Why do I need this on a desktop? I remember how new ICQ, which renewed itself without demand, shocked me one fine summer morning.
All peace, health, prosperity and more nice gifts!
Thank you for your attention!

Many radio amateurs use transformers as the basis of power supplies, including for power amplifiers. When it comes to estimating the data of the transformer windings and other elements of the rectifier circuit, certain difficulties may arise.
The "PSU Designer II" program is a simulator of a conventional linear unregulated power supply unit and allows you to select a transformer and other circuit elements, help you "see" the voltage and current at various points in the circuit, "play" with the ratings - in general, good tool for virtual experiments.

On the own experience convinced of the wonderful properties of the archiver 7-Zip... Sevn-Zip shakes better than Zip and Rara! My old favorite WinRAR is often left behind by 7-Zip.
Besides, the program is FREE, unlike RAR and ZIP. The developer made such a gift to the Universe Igor Pavlov(Russia).
Therefore, I declare the archiver 7-Zip our official archiver and I invite all datagoreans to actively use 7-Zip when preparing materials for posting on our website: we save disk space and do not violate copyright.
The program has a Russian interface.

In each of its eight sections, there are up to a dozen interactive pages, through which you can calculate almost all conceivable parameters and characteristics of simple circuits, elements and devices. For example, in System section you can set a range (from EZ to E192) of nominal values ββof elements (Prefered components), hot keys (Hotkeys), etc. In the Miscellaneous section of the Sound page, you can get frequency characteristics sound absorption coefficient in air depending on relative humidity, temperature, convert frequency to length acoustic wave, sound pressure(dB) into the loudness level (background) and vice versa, weighting curves A, B, C, D, U, AU. The Weather and Air page provides for the calculation of boiling points and dew points and even ... the power of a wind farm depending on wind speed, blade diameter and air temperature. The Photo lens and Photo light pages are devoted to calculating lenses and illumination (exposure). Of course, you can calculate the rms, average, amplitude values, shape and amplitude coefficients, slew rate of signals standard form(sinusoid, including limited, triangle, saw, meander) and arbitrary (specified in a table or formula) form - on the Waveforms page of the Calculations section. Here, on the pages of Wires and Unit conversion, you can instantly convert the wire diameter in millimeters to the equivalents of AWG, SWG, mils (and vice versa), calculate the resistance of the meter, mass, losses for a wire made of copper, gold, lead, molybdenum, nickel, tungsten, zinc and other metals, as well as mercury. In the Mechanical section, the Fan cooling and Heatsink pages allow you to calculate a fan and a passive radiator for cooling both the case as a whole and a separate radio element. The Printed circuit board page will help you determine the resistance and maximum current through the printed circuit, as well as calculate the microstrip lines. V section Components especially attractive Color page codes, in which, by color coding, you can determine the value of not only the resistor, capacitor and inductance, but also the type of diode, as well as create your own color coding up to 8-digit numerical value... The Thermo sensors page allows you to design all types of thermocouples and temperature sensors such as PT100 and NTC. The Components type numbers page decodes its assignment according to the standards of Pro-Electron, Jedec and others by the input element designation. The Leds page is devoted to the calculation of nine circuits of LED drivers of different complexity - from power supply constant voltage through a resistor or integral stabilizer before supplying alternating current through ballast resistors / capacitors and rectifier diodes / bridges. Immediately on colors can be determined standard color LED and its wavelength.

Programs created specifically for or used by radio amateurs can make the design process more enjoyable, check certain calculations, pick up the necessary parts, and many other useful things. Since the radio amateur business already requires money, it is advisable to find out about free programs for radio amateurs. And this article contains just such a selection of useful functionality.
Why are programs designed for radio amateurs created?
What software designed for radio amateurs can help with?
What problems or tasks do the programs for radio amateurs help to cope with? If you need to check or calculate in advance the operation of microcircuits or microcontrollers, then there is such software. Do you need to theoretically measure the voltage at some node? There is software that will do this too. Model how everything will look visually? And this is possible. And it's not worth talking about calculating calculators, reference books or part identifiers - there are a lot of such programs. Now let's move on to dubbing what free programs for radio amateurs are, and why they are useful.
Software designed to work with a microcontroller or microcircuits
Radio amateurs working with the AVR will be delighted to make the programming process easier. And specifically for this, the ForMC program was created. It allows you to determine the character code, generate it, calculate the constants for the interrupt memory in order to obtain the required execution speed of the tasks assigned to the microcontroller, convert monochrome pictures with the extension 128 * 64 into a representation of the "data array" type, in order to subsequently use it in the microcontroller program for graphical indicator.
If a radio amateur works with a circuit and wants to do sound card, which will reproduce sounds of a certain frequency, is useful software program there are so many such purposes and they are created for such a number of purposes and for such working conditions, and others like them, that they are specific example specific software makes no sense. For each computer and special conditions (frequency, microcircuit, etc.), you can choose separate application, which will allow you to fully implement your ideas.
Measuring software
Very wide range applications can be entered here. Alas, the size of the article does not allow describing all kinds of software and the programs themselves that can be used by radio amateurs in their creative searches. But some are worth considering.
Coil32 software will be loved by those who work with winding elements (design of receivers, transmitters, acoustic systems). It is used to calculate the required full-fledged work... The positive properties, first of all, include the fact that the program is quite universal and cross-platform, which is quite important for those who often change computers.
Visualization software
Such programs help to better understand what kind of creation will have, calculate everything you need and how it will be placed.
Program Sprint Layout used in the design of low and medium complexity. The main advantages include a simple and intuitive interface that has everything you need and nothing more for working with boards. It is not suitable for professional research, since the program can only calculate boards small size that do not have a significant number of elements. That's not all useful programs, further more.
Calculator program
Programs not in the sense that ordinary calculators, but in the fact that they help to calculate required parameters for work. Let's take as an example a program such as the Electrician's Calculator, developed by a user known as Ivan219. In terms of its functionality, this calculator can be compared to a food processor, but for a radio amateur. The program calculates inductance, resistances, coils on and core, and much more. There is also a small guide to chokes and SMD transistors here. And the functionality of the program does not end there: here you can find analogs for transistors or microcircuits. This is not only a calculator, but also a radio amateur's reference program, we think readers understand why there is such an enthusiastic opinion about it.
Reference programs
Virtually no circuit can do without a resistor. It so happens that you need to buy a transistor, but there is no way to understand it. Rezistor v1.0 fixes this flaw. It is designed to work with phones, and if you have games running on your mobile, it will also start. With its help, you can select the external one in front of you, and the program will immediately show its resistance. In general, there is one trick in the work: the program is distributed in the Czech language, but this is not a significant problem: everything is clear at an intuitive level.
The use of transistors is also popular. The "Transistor" program by Valery Kucherenko will help in determining the part that is in front of the radio amateur. Determination is carried out by markings. The pluses of the program include the fact that it even contains transistors with non-standard markings.
And if you want to chat with other radio amateurs, then there is such a program. It is called "The virtual organ: a program for radio amateurs." It is used to communicate on 4 frequencies, where someone is sitting. And from those who are in touch, you can get a full consultation on the implementation of some work. But useful programs don't end there.
There is one more good universal development, with the help of which you can figure out which resistor or capacitor is in front of you by color marks. In comparison with the Czech program, the interface is slightly less intuitive, but more functional in Russian. Oh yes, the program itself was not specified - this is Resss.
Programs for the parts with which the work is in progress
If you are working with a transformer with a power of up to 500 W, having a frequency of 50 Hz, then useful service you can be helped by the Transformer program. It will facilitate the assembly of your own power supply.
Also, those who often work with inexpensive industrial speakers know that calculating filters by hand is quite a long time, so any method of making the work easier will do. Especially for such people, a program was created to determine the AC filters using calculations based on the formulas of Aldoshina and Tereshchuk.
Hello everyone! I climbed a lot on the site, and especially on my own branch and found a lot of interesting things. In general, in this article I want to collect all kinds of amateur radio calculators so that people do not look much when the need arises for calculations and design of circuits.
