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:
