A homemade remote antenna switch made with an Arduino Uno by KK7S

Manufacture remote control interfaces to manage several kind of ham radio transceivers, Antenna rotators and antenna switches. Control can be done using smartphone Apps or from Computers.

In pursuit of enhanced station efficiency, the author describes crafting an Arduino-based smart antenna switcher for an SO2R setup. Faced with manual antenna switching challenges during contests, the project utilizes a Logos Electromechanical 4x4 Driver Shield and a Power Screw shield for seamless functionality. Despite its raw appearance, the automatic switcher proves indispensable in contest scenarios, prompting considerations for future improvements and standardization of station control protocols.

Building an automatic 8ch USB Relay switch using an existing Ameritron RCS-8V Remote Control Coax Switch and an externally mounted 5-way switch.
