I did the project as explained on the website and in the video and it worked perfectly but:
1 - The initial value starts from 1003, have any problems?
2 - The transmitter and receiver are still with the test code, but the range is no more than 10 meters ... could you help me?

1. Tchange that range in the receiving code when you map the received values from 0-254 to 1000-2000 and solve the problem.

2. Are you using power amplified antenna for the transmitter? Also, if you are using the PCB antenna, you could solder a small copper wire like this: https://cdn.instructables.com/FAK/6SB5/ID7US7VX/FAK6SB5ID7US7VX.LARGE.jpg Also, you should use small wires for the SPI communications for less noise.
