SDR radio receiver for computer. How to receive signals from 10 kHz to 1000 MHz

I recently purchased an SDR radio receiver that connects to a computer. With this radio receiver, you can receive broadcast radio stations on long, medium, short and ultra-short waves with AM, FM modulation, as well as radio amateurs with SSB and CW (Morse code) modulation. The receiver operates at frequencies from 10 kHz to 1000 MHz, but in reality it can operate up to 1900 MHz.

Let me tell you a little about this receiver

I bought a complete set. It includes an antenna, a receiver, and a cable for connecting to a computer's USB port. There are five antenna inputs on the case, each with its own frequency range. Each range must have its own antenna that will work well at these frequencies. Let's say a 50 cm long antenna wire will not work at frequencies of 0-30 MHz, and a 30 meter long antenna wire will not work at frequencies of 250-1000 MHz.

The receiver contains two chips: MSI001 and MSI2500. The MSI001 chip receives DVB-H/T signals (T-DMB/DAB, ISDB-T, DRM, AM/FM, HD radio) and works accurately up to 1675 MHz. The MSI2500 chip is used to convert analog signals to digital, processes signals from the MSI001 chip and transmits them to the computer.

Each antenna input has its own filter, which passes signals of the required frequency range and suppresses unwanted signals at other frequencies. However, there is no signal limiter on two diodes at the antenna inputs, so care should be taken when connecting external antennas to the receiver

For the receiver to work, the program for SDR receivers must be installed on the computer. There are about a dozen of them on the Internet, if not more, I installed the SDRuno program, and it also selected a driver for the receiver.

To receive signals on long, medium and short waves, I connected an antenna to the 0-30 MHz input, this is a 30-meter-long wire dropped from a height of 10 floors. In the morning, I received dozens of broadcasting stations on HF with such an antenna, as well as conversations of radio amateurs with SSB modulation, and also Morse code on 80 meters. On long waves, I caught the airport beacon on 315 kHz and stations on medium waves

Then I connected the short antenna from the kit and checked the signal reception at 146 and 433 MHz. The reception was excellent. I also caught all the broadcast FM radio stations. To receive the airport signal, you need a good directional antenna if the airport is tens of kilometers away from you

To test the receiver at frequencies above 1000 MHz, I took a base from a radio telephone that emits a signal at frequencies of 1880-1900 MHz

Conclusions on this receiver. If you are interested in radio reception and you do not want to buy a separate expensive radio receiver, then such a receiver-set-top box for a computer will be an excellent and inexpensive solution
