Description

This is a kit that provides an external clock interface to the QDX transceiver, greatly improving the frequency stability.

Please note: These interface boards are only compatible with QDX hardware versions 4 and later.

If you have a 25 MHz source, the Direct Board will couple this to the QDX clock system.

 

This kit includes a replacement back-panel for the QDX, with a hole for the interface SMA jack.  Also included are lengths of wire used to connect the interface board to the QDX.

Some soldering is required, and a small surface-mount capacitor on the QDX board must be removed.  Here are more details:
