(14 March 2022)
Russia began a full-scale invasion of Ukraine on 24 February 2022, in an escalation of the Russo-Ukrainian War that began in 2014. The invasion is the largest conventional military attack on a sovereign state in Europe since World War II. Since the beginning of Putin's war, thousands of both Ukraine and Russian citizens have been killed. Russian military have indiscriminately bombed cities in Ukraine, destroying many hospitals and schools. Our heart goes out to the 2.7 million plus refugees that have left Ukraine for neighboring countries, and those who stayed to fight the Russian invaders.

Россия начала полномасштабное вторжение в Украину 24 февраля 2022 года в рамках эскалации российско-украинской войны, начавшейся в 2014 году. Это вторжение является крупнейшим
военным нападением с применением обычных вооружений на суверенное государство в Европе со времен Второй мировой войны. С начала путинской войны погибли тысячи граждан Украины
и России. Российские военные без разбора бомбили города Украины, уничтожив множество больниц и школ. Мы сочувствуем более чем 2,7 миллионам беженцев, покинувших Украину в
соседние страны, и тем, кто остался сражаться с российскими оккупантами.
YAGio - Yagi Design by W8IO
YAGio 1.01 is the most current released version. YAGio runs under Windows 2000, XP, Vista, Win 7 and likely Win 8. YAGio is similar to LPCAD, it uses keyboard commands instead of a mouse menu. YAGio allows you to create DL6WU long Yagi antennas on any frequency, typically on VHF and UHF ham frequencies. You specify the frequency, desired gain, type of element to boom mounting, DE diameter and parasitic element diameter, and YAGio does the rest. You can save these designs in 5 different formats - YIO (used by YAGio), NEC (used by 4NEC2), YAG (YO), MMA (MMANA-GAL) and YC6 (used by YagiCAD). You can also print the results to your Windows default printer. Please email me at rgcox2 (at) gmail.com if you find bugs or to suggest improvements. YAGio.exe version 1.01 was created on 6-10-2015 at 12:39 pm. The exe file size is 221K. You may download YAGio101.ZIP here.
I am currently working on YAGio 1.02. I will also add file export support for 4 bay NEC models.
I like to use 4NEC2 to evaluate my Yagi models. It is a very nice, full featured version of NEC2. You can find the latest version of 4NEC2 here:http://www.qsl.net/4nec2
You can also find a faster NEC2 "engine" for 4NEC2. (web site currently unavailable) The NEC2/MP "engine" will speed up computation tremendously in dual and quad core PC's. A model that took 60 seconds to run in 4NEC2's existing computation engine should complete under 25 seconds using the NEC2/MP engine in a dual core CPU and under 12 seconds in a quad core CPU.
Here are a couple screen shots from YAGio 1.0 running in Win 7:
The most satisfying move in the game is clearing four lines at once—the "Tetris." To do this, leave a single column open on the far right or left and wait for the long bar to appear. 3. Look Ahead

Eventually, you will mess up. You’ll place a block awkwardly, creating a jagged skyline. Panic is the enemy.
refers to the integration of the classic, falling-block puzzle game into the Echalk educational platform. It offers a streamlined, ad-free, and safe version of Tetris designed specifically for a classroom or remote-learning environment.
Try to keep the top surface of your blocks as level as possible. Avoid creating deep "wells" or "towers" that make it hard to place the next random piece. The most satisfying move in the game is
Left/Right Arrows: Move the falling piece (Tetromino) horizontally. Up Arrow: Rotate the piece 90 degrees.
A quick, 5-minute session can help students refocus after a difficult lesson.
