The four capacitors for the signal input can be removed. C2, C3, C5, and C7 are two 24pF and two 220pF 
 
capacitors. It's best to choose a different package for the signal relay; the relay I purchased is significantly larger. Also, it's best not to place the signal relays side-by-side, as it causes significant difficulties during soldering.
 
Adding some test points can improve testing (I've seen many problems with this in the training camp).
 
Try adding a reset button and a power switch; this would be much more convenient (or provide a via for pressing the reset button).
 
It's best to replace the selected encoder, as it's quite expensive. Consider replacing it with a plug-in encoder or a cheaper one. The encoder's button can also be utilized to replace a physical button.
 
The spacing between the SMA connectors can be increased; even a slight misalignment makes them difficult to screw in (SMA connectors can have their signals soldered first, while GND connectors are too large to solder easily).
 
The position of the surface mount female connectors can be repositioned to accommodate BNC sockets between boards. Converting SMA to BNC is quite complicated
 
. Some holes in the 3D template are designed to reduce errors in PCB design and can be reduced as needed.

V1.1 The relay package has been modified, but the spacing is too small, which can easily cause problems.
