Indeed, in my experience, the performance of this receiver is much better compared to its cheaper “relative”. This ensures better signal reception and more information that can be obtained from it. According to them, the board is designed better, has more stable workflow, less noise, heat dissipation, and good chip R820T/2. My second receiver is device from radio amateurs from RTL-SDR Blog.

Maybe you can give it a try if find that receiver for free somewhere. Even if you just want to try SDR, this receiver is still a bad option. But this receiver has a narrower frequency range, more noise, also it badly holds set frequency and overheats quickly, which worsens the already not perfect performance. This exact model can be quite easily bought on Ali Express. Also frequency range of 22 – 948.6 MHz in the worst case (super-cheap tuner FC0012) or 24 – 1766 MHz in better case (slightly more expensive and rarer tuner R820T/2)! Opportunity to acquaint oneself with the world of radio communication for such price is very incredible. For $10 (cost of a ready-made(!) DVB-T receiver) user gets a receiver with a bandwidth of 3 MHz and no restrictions on tuning accuracy or modulation type. This key fact that computer, not the chip, processes the signal, became a basis for creation of Software Defined Radio (abbreviated SDR) based on this platform and ushered in the era of RTL-SDR. Workflow of this device quite simple – built-in chip digitizes high-frequency signal, then computer and software extract desired frequency and information from it. Originally, no one guessed about other possibilities of this receiver other than digital television.
Although DVB-T (not to be confused with DVB-T2) has not become widespread, the RTL2832U chip has become a real discovery for radio amateurs.

Its main purpose to receive first-generation digital television broadcast on computers and portable media. But there is a very popular, and most importantly cheap device for receiving signals – DVB-T receiver with chip RTL2832U. Professional radio equipment for receiving or transmitting radio signals, like any other non-mass equipment – not cheap equipment.

Today I will tell how to get a picture of the Earth from NOAA satellites within the city with a minimum set of equipment – an SDR receiver from RTL-SDR Blog and a conventional dipole antenna.
