Elecraft KX2 / KX3 Setup

Please follow these steps to connect and use DigiLink Nano with Elecraft's KX2 and KX3 transceivers.

Make sure you already set your Windows or macOS computer up for use with DigiLink Nano.

Now connect DigiLink Nano to your Elecraft KX2 or KX3 tranceiver with the included cable. Depending on when you ordered your DigiLink Nano, you will have one of two cables.

Cable with all black connectors

The stereo jack with the white tip needs to be connected to the MIC socket and the jack with the black tip goes into PHONES. The other end of the cable connects to DigiLink Nano.

Cable with red and green connectors

The green connector goes into the PHONES socket at the KX2/KX3 and the red connector goes into the MIC socket. The black connector goes into DigiLink Nano.

Use your computer's sound settings to set the output level to 100% and the input level to about 30% (see Windows and macOS guides for instructions). Adjust your Elecraft's AF gain to suit the needs of your digital mode software (15-20 is about right for most cases) and the MIC gain so that you see 3 to 4 ALC bars when transmitting. The frequency response of Elecraft's KX line is excellent and makes re-adjustment unnecessary when changing audio frequency.

Please also use these settings for best results:

- TRX Mode: DATA A

- Extend filter to 4000 Hz, center at 2000 Hz

- Use an appropriate power level. This very much depends on your environment and the SWR of your antenna, but around 50% of the maximum output power is a safe value.

- Mic bias can be on or off
