Quick Overview

Portable Transceiver 160m - 6m


ELECRAFT KX3-K is available to buy in increments of 1

The Elecraft KX3 uses SDR technology to bring to you a level of performance that is above most base station transceivers regardless of price. Yet it is a light weight portable package that you can take almost anywhere. And as well as now offering an increased power output of 15W on bands from 20m and below, it can also send and receive PSK31 and RTTY.  It’s a great package.

 You can also expand the KX3 further.
