[Elecraft] Installed K3EXREF

[Ron D'Eau Claire]

Installing the K3EXREF involves installing a connector/cable assembly in the
REF. hole in the K3's rear panel and running the cable under the RF board to
the front panel shield, then up behind the front panel shield. The other end
plugs into the TMP connector on the KREF3 reference oscillator board that
sticks through the hole in the shield. 

A small pony board plugs into the connector on the component side of the
KREF3 board, held in place by a screw that passes through it and the KREF3
board and into the PEM nut in the shield. 

The biggest part of the project is taking the left side off of the K3 to
install the cable. If you have the K144XV installed, it needs to be removed.
If you have the KRX3 subreceiver, it can be left in place. You do *NOT* need
to remove the KRX3 module with all its cables. 

Ed's time of 1.5 hrs sounds about right for someone working carefully and
methodically, doing the job for the first time. There's no soldering, of
course, but still a fair bit of mechanical disassembly/reassembly. 

After doing it several times, I can probably do it in 30 minutes or a bit
less without rushing.

That seems quite a long time to install it, Ted. What's involved?  I
have looked for the manual on-line but it does seem to up there yet.

Any more details would be appreciated;  I'd like to order one.
