We've come up with something that works well <br />enough to share.<br />What you do is use two 2.5mm (3/32") audio jacks, mounted on 0.486" centers, <br />for the crystal to plug into. If you are using a metal front panel and panel <br />mount jacks, you'll have to isolate the shell of the connector from the front <br />panel with fiber washers or something similar. Tie all the contacts of each <br />connector together, and there you go!<br />Hope this is useful!<br />73 Dave Cripe NM0S<br /><br />------------------------------------------<br /><br />Possibly of greater interest is the post below that mentions AF4K sells FT-243 sockets. Not cheap but if you crave something OEM-like, it might fill the bill.<br />http://www.kkn.net/archives/html/QRP-L/2016-04/msg00454.html<br /><br />AF4K sells both ceramic and plastic versions.
