NaP3 Software Defined Radio Demonstration
using the Elecraft KX3
This is a short tutorial on how the KX3 can be used as a Software Defined Radio when
hooked to the NaP3 SDR software program in your computer. At the bottom of this page is
a link to a video demonstration of how to configure NaP3 to work with the Elecraft KX3.  The Elecraft KX3 is a very capable radio. It is a 10 watt transceiver that covers 160 through 6 meters and accomodates SSB, CW, AM, FM and digital modes. In addition it is a Software Defined Radio (SDR) and has a jack on the side which provides the I/Q output. By connecting the I/Q output of the KX3 to the line input of a sound card it can interface to SDR software packages such as PowerSDR, SDR # and NaP3.
I bought the KX3 cable packet from Elecraft. It has all of the cables necessary to do
anything you want with the KX3. They are all rear-facing cables and make a
very tidy installation.
To isolate the KX3 from the computer sound card, I use a ground loop isolator.
The one I use is the PAC SNI 1/3.5. unless your sound card has isolation built-in,
you will need one of these. I am presently using my KX3 as an SDR and am using NaP3 software. You can view a demonstration of NaP3 by clicking on the image below. Click below to view the NaP3 KX3 video: |
