This is weird. K3

[Paul VanOveren]

All of a sudden my K3 # 758 is acting weird.   It recognizes the ATU in that
the little ATU is present on the display, but no signals are received in the
radio, only a hiss.  If  I try to adjust the power setting  it will read
from 0.10mw and - 10.0 db  to  1.5 mw and 1.8 db on the display, it stays
there for only a second or two and then the display return s to normal.

Altho the atu is showing on the display and I tap the tune button, the
display changes to NO ATU and the normal clicking sounds is not there.

When I hold the XMT button to perform the Tune function, the display changes
to 1.8 db and 1.5 mw rather than the swr and power, it does change to the cw
mode however.
This all happened after I unhooked the rs232 cable from the back of the K3
so I could plug in my Yamaha CM-500 headset, which I removed for a day. Just
for grins I went to the K3 Utility and did the resore K3 configuration
button. Presto, signals back, power control normal, ATU clicking again, Tune
fuction reading swr and power...I am so glad, but can anyone tell me why
removing the cable from the laptop to the K3 evidently corrupted something?

Sincerly,

Sounds like the CONFIG KXV3 menu item got set to TEST.  This routes all the
RF to the xverter BNC outputs at low power.   See page 49 of the current
manual.  Restoring your configuration probably corrected it.
