The TX/RX-switch is a tool for signal sensitive or PTT switching for HAM radios incl. pcb schematics.

DISCLAIMERS

This is still "work-in-progress (WIP)" so I do NOT take any kind of responsibility for damages/data losses!

You can use this at your own risk without guarantees and put device on non conductive surface or enclosure!

If you like the new design yo are free to share it!

Have fun :)

The new design was checked by the electrical engineer theBrutzler (https://github.com/theBrutzler/)

The new optimized PCB was designed with free KiCAD software (https://www.kicad.org/)

:heavy_exclamation_mark: The PCB should be produced at a manufacturer

(like PCBWay or similar) with the RoHS lead-free option for environmental protection.
