HackRFOne Replica V2.0

The HackRF One is a software defined radio peripheral capable of transmitting or receiving radio signals from 1 MHz to 6 GHz. Designed to enable testing and development of modern and next generation radio technologies, the HackRF One is an open source hardware platform that can be used as a USB peripheral or programmed for standalone operation.

Functions that can be realized
It can listen to FM, AM, shortwave, medium wave and other radios, and can also be used to learn high-frequency electronic circuits, "steal cars", and simulate GPS positioning, so that you can complete the school running task without holding a mobile phone. It can also complete a simple base station construction.
Seriously speaking, it can realize spectrum analysis of radio signals, interference detection, signal capture, signal recording, signal playback, FM radio transmission, Morse code transmission, tire pressure detection, SSTV image transmission.

  
 Friendly reminder:
  Although HackRF is a radio experimental platform, it involves radio transceiver related operations. It is limited to learning radio knowledge and experimental use. Please comply with radio-related management regulations and laws and regulations, and do not use it for illegal purposes. Children's shoes who are interested in SDR and radio can consider obtaining an amateur radio operation certificate and obtaining a call sign for legal use.

There are many software tool libraries that can be used for software radio development. I personally recommend using gnuradio.
Regarding the study of gnuradio, it is recommended to start with some small examples and gradually go deeper.
Reference learning books or websites include:

Supplement:
Some components (about 10%) cannot be purchased in LiChuang Mall, you can consider buying them on Taobao. Clock generation IC (SI5351C) is currently out of stock and may be expensive (emmmm...about 400 yuan per piece). It is recommended to purchase from LiChuang Mall overseas or order from Mouser (about 38 yuan per piece, but you need to wait for delivery). Remember not to use SI5351A or SI5351B to replace SI5351C. The A/B version does not have CLKIN, which will cause some functions to malfunction.
The HackRF project is expensive (about 800-900 yuan, but it will have more functions...). If you are just getting started with amateur radio, you can consider buying entry-level equipment with lower prices such as: RTL TV stick (tens of yuan), RSP1 (more than 100 yuan), RSP1A (more than 400 yuan), etc. Finally, welcome to the world of amateur radio.
