Were you only holding the nut while tightening and the ferrule cracked? That is the first case I've heard of in the 5 years the K3EXREF option has been shipped so it's possible there's an issue with some units, especially since there are two cases.
I'm curious because we might need to alter the procedure in the manual a bit if it's something happening during installation. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:[email protected]] On Behalf Of Mike Cox Sent: Saturday, April 2, 2016 2:59 PM To: [email protected] Subject: Re: [Elecraft] KE: issue with installation of K3EXREF interface Mine broke off too. It appeared for be a crimped ferrule but it split and fell off as though it were already fractured. I carefully soldered the coax braid to the connector to maintain the electrical connection. I was careful not to overheat and melt the dielectric of the coax which could have shorted the center conductor to the shell. It's working well!
