KX3/KXPA100 Change

Carter Craigie
Hello Fellow Elecrafters,
I have an Elecraft KX3, connected to an Elecraft PX3, and both are connected
to an Elecraft KXPA100 Amplifier, and to my Dell laptop computer.
All had been working well, and before leaving for an out-of-state trip, I
disconnected the antenna cable from the rig, as well as the power cable. I
may have disconnected something else, but all cables are now connected right
where they should be now.
Upon returning from the trip, and re-plugging everything, I can get no more
than 5 Watts out of the KX3.
The green LEDs illuminate on the KXPA100 Amplifier, and the Switch is in the
OFF position. The KX3 is receiving properly with good audio, and all signals
show correctly on the PX3.

On the KX3 the flowing menu items are set, as per the manual:

PA MODE: ON
RS232: 38400 b

The KX3 Serial Number is 4240.
MCU Revision 02.38. RS-232 speed 38400 bit/s. Computer Port COM3.
DSP 01.37 RS-232 speed 38400 bit/s. Computer Port COM3.


The PX3  Serial Number is 1016.
MCU REVISION 01.39, RS-232 speed 38400 bit/s. Computer Port 3.

The KXPA100 Serial Number is 1515.
Revision 01.39. RS-232 speed 38400 bit/s. Computer Port COM3.

I'm stumped. Why can't I raise the power level up to 100 Watts, as I had had
it before?
Any help, please?
(If I have omitted any pertinent data, please ask me, and I can add them.)

73,
Carter Craigie, N3AO
Blacksburg, VA

Carter,

As a first step:
Check the seating of all the plugs, give them that 'extra push'.
The is especially true of the RJ-45 plug.  Remove it and make certain it
goes back in with a little click.

Elecraft CS suggested wiggling the RJ connector, too, but I found the
problem was wiggling the 2 plugs at the other end of the cable.

Also [egg on face] I once had one of those plugs plugged into the RX I/Q
jack instead of ACC
