ATTENTION: This board is not compatible with Arducon. It is the correct board for SignalSlinger only.

This is a small board to go between a 6-pin header and a DB9 connector. This is used to create a serial communications and/or programming cable for several OpenARDF projects. It is compatible with AdaFruit’s FTDI cables, such as https://www.adafruit.com/product/70.

DON’T ORDER THIS YET!

Experimental Version X2: to be used for development and experimentation.

This is a stand-alone 80m tuned-loop ARDF antenna, compatible with the Receiver Development Platform. Will also work with other 80m receivers.

Prototype

The board is for use in a short Ground Plane (GP) antenna for Amateur Radio Direction Finding (ARDF), with a single loading coil and matching circuit at its center feedpoint. It is designed to operate between 3.5 MHz and 3.6 MHz with an SWR below 1.5:1. Simply suspend the far end of the antenna six meters above the ground, plug the other into an 80m ARDF transmitter, and fox setup is complete.

The board is for use in a short vertical dipole (SVD) antenna for Amateur Radio Direction Finding (ARDF), with a simple matching circuit at its center feedpoint. It is designed to operate between 3.5 MHz and 3.6 MHz while providing a 50-ohm resistive load with an SWR below 1.5:1. The coax feedline runs up the center of the bottom antenna element and is shielded by it. The result is a “rope antenna” about 6.1 meters (20 feet) in length. Simply suspend the far end of the antenna six meters above the ground, plug the other end into an 80m transmitter, and the fox setup is complete.

A snap-off wire end insulator is included as part of the board design.

Arducon is a transmitter controller for Amateur Radio Direction Finding (ARDF). The project is based on the Arduino Pro Mini, and it includes everything needed to create printed circuit boards and executable software.
