Arduino Callsign beeper PCB and programmed Arduino for CW

Callsign beeper CW kit interface for microwave path lineups

Callsign beepers are essential for path lineups on microwave frequencies. This simple CW generator plugs directly into the CW jack of your radio or any other ground-switched transmitter. It also has a +12v output a a header pin for a visual indicator that you can put on the side of the box, or you can use it to drive a GALI84 stage for a RF beacon.

See the Callsign beeper CW kit interface for microwave path lineups blog post to download the sketch as well as more information including the parts list. This project produces an output that closes the CW circuit in your radio.  It also has a +12v output should it be needed for other projects.

What’s available here is an unpopulated PCB as well as a pre-programmed Arduino Nano with your callsign. No components are supplied, just the PCB and a programmed Nano.

The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano 3.x). It has more or less the same functionality of the Arduino Duemilanove, but in a different package. It lacks only a DC power jack and works with a Mini-B USB cable instead of a standard one.
