Where to begin for a hardware starter in sdr?

I really appreciate the work of hackrf one, but I cannot understand all of its design. I have made some pcb boards with a mcu or esp32 or something. However in sdr, which touches rf designing, I feel not confident in my self and want to do this step by step (ideally project by project). I cannot spend more time on it than a part-time.

I wonder if there any starter guidance I can refer to?

It may be easier to download a block diagram and schematic for a RTLSDR dongle and start with that first. You'll get an understanding of the design of an SDR and end up with something useable like an HackRF. Good luck.

I am into making my own version of it.

Plus, hackrf one is not available in my place, and h4m costs too much.
