The TX/RX-switch is a tool for signal sensitive or PTT switching for HAM radios incl. pcb schematics.
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 :)
1x Custom PCB by WodoWiesel
1x USB-X cable for power supply
1x THT-SPDT relay +5V
3x THT-BNC female socket connector
1x THT-1N4001 flyback suppression diode
1x THT-2N3904 (TO-92) BJT transistor
3x THT-LED green+orange+red (tx/rx/pwr-indicator)
2x THT variable resistors 3-pin (~50-1kOhm)
1x THT-3.5mm socket (optional)
1x cable for PTT (optional)
1x enclosure/box (recommended)
1x Soldering iron
Solder + flux + IPA
No need for that.

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.
