1. Move trace that's under the screw for the PA heatsink to avoid possible +5V-Gnd short
2. Use only half the BPF MUX switch to reduce parasitics and insertion loss
3. Add 5.1K resistors at USB CC pins to fix the USB-C recognized issue
4. Move capacitor C204 that is near the mounting hole for the left SMPS board
5. Make 0.6mm wire holes larger on binoculars
6. Enlarge some 3.5mm jack holes very slightly to make it easier to adjust their position
7. Move part of the power connector +12V pad to avoid nearby short
8. Make the ground connections of the rotary encoder pins easier to solder
9. BS170 holes slightly larger to make them easier to replace
10. Possible SMPS short area: moved Q103/Q104 transistors further apart slightly to avoid risk
11. C204 was 100n now 1n
12. Move MIC leads a little apart to better match the supplied mic
13. Tidy up spacing of C401/2/3/4
