[Elecraft] dead K2

[W3FPR]

Oscar,

First remove the KAT2 from the K2 entirely, including the cable to the 
control board.
Then connect a dummy load to the BNC on the lower rear panel.
Try transmitting (do a TUNE) and see if there is any RF.  If there is, 
you are fortunate, fix the coax ground to the KAT2 and put it back together.
If not, you have some troubleshooting to do.  Get an RF Probe (or an 
oscilloscope) and follow the procedure for troubleshooting that is 
printed near the back of the K2 manual (download if you do not have a 
printed copy).

Until you find the failure point, that is all I can tell you.

A serial number will be helpful.

You might also contact Elecraft support, and Dave W8FGU can likely help 
as well - he is the official contact for support on the legacy gear (K1, 
K2, KX1).

73,
Don W3FPR

I noticed that the radio was "deaf", so I did a tuning cycle and my radio turned off completely, I checked everything on the outside and it looked good, I checked the power and it was fine (13.2 v), the antenna was fine, so I removed the top cover and that was where I saw the "big problem", the coaxial that carries the RF from the board to the tunner was loose (the ground part of the coax was broken), in the physical inspection everything looks fine, no "pop" was heard,  There was no smoke anywhere or a burning smell, so I have no idea where to start, any advice would be greatly appreciated.
