Бесплатный радиоприемник ДВ, СВ, КВ и УКВ диапазонов.

Good instruction. Below we wrote about the broadcast through the WEB of various, type, radio stations. These are completely different stories. WEB-SDR is a unique service that only radio amateurs could come up with. We connect to a real SDR receiver that has reception parameters and a real antenna. The owners of the receivers kindly provide the opportunity to everyone who wants to turn the knobs of the receiver, go through the ranges, evaluate the passage at different times of the day on different content. You can connect to a US receiver during the daytime (local) and listen to an almost deserted medium wavelength range. And then, when night falls in the USA, connect to the same receiver again and listen to the abundance of radio stations on medium waves. And you can find a receiver in Australia and listen to the broadcast on the Australian continent. Again, do not forget about the specifics of the passage. The transmission of radio waves on different bands depends on the time of day and on solar activity. Magnetic storms also affect short waves. Transmission at frequencies of 27 - 30 MHz makes it possible to estimate solar activity. No need to watch summaries and read the media. It is enough to turn on the receiver during daylight hours on any continent and check for the presence of radio stations. If there are radio stations on the 10 meter section, then the Sun is active. And vice versa.
