Рекомендуем ресурс, на котором собраны несколько калькуляторов, связанных с fpv-радиосвязью.
✅ Перевод мощности из мВт в дБм. ✅ Потери мощности в пространстве исходя из частоты и расстояния. ✅ Примерный расчет дальность исходя из: частоты, мощности, коэффициентов усиление антенн, чувствительности приемника и т.д. ✅ Перевод изменением мощности из дБ в разы изменения дальности.

Some people used the platform to organize ahead of the storming of the U.S. Capitol in January 2021, and last month Senator Mark Warner sent a letter to Durov urging him to curb Russian information operations on Telegram. For example, WhatsApp restricted the number of times a user could forward something, and developed automated systems that detect and flag objectionable content. Just days after Russia invaded Ukraine, Durov wrote that Telegram was "increasingly becoming a source of unverified information," and he worried about the app being used to "incite ethnic hatred." The next bit isn’t clear, but Durov reportedly claimed that his resignation, dated March 21st, was an April Fools’ prank. TechCrunch implies that it was a matter of principle, but it’s hard to be clear on the wheres, whos and whys. Similarly, on April 17th, the Moscow Times quoted Durov as saying that he quit the company after being pressured to reveal account details about Ukrainians protesting the then-president Viktor Yanukovych. Telegram was co-founded by Pavel and Nikolai Durov, the brothers who had previously created VKontakte. VK is Russia’s equivalent of Facebook, a social network used for public and private messaging, audio and video sharing as well as online gaming. In January, SimpleWeb reported that VK was Russia’s fourth most-visited website, after Yandex, YouTube and Google’s Russian-language homepage. In 2016, Forbes’ Michael Solomon described Pavel Durov (pictured, below) as the “Mark Zuckerberg of Russia.”
