[Elecraft] KE: issue with installation of K3EXREF interface

[Jim Spears]

While installing the K3EXREF SMA-TMP cable, I ran into an interesting issue
which I do not yet know if it is a problem or just interesting.

 

There is a ferrule or something similar over the cable where it attaches to
the SMA fitting that is installed on the back panel.  while tightening the
hex nut down, I must have torqued something as the ferrule broke into two
pieces and fell off.  I finished off the installation and verified that the
GPSDO does provide a suitable 10 MHz signal into the radio.

 

So the question becomes:  is this interesting or a problem?   I took a close
look and the problem might be improper grounding of the shield to the
chassis at the SMA connector end.  

 

If it is deemed to be a potential problem, I can request a new cable from
support.  It will not take long to replace the cable.
