It seems that something let my K2 stuck in TX mode. I removed all
module and put appropriate jumpers (unmod kit). Still in TX when
powered ON. I checked this using my DL2 dummy load with my
multimeter.... I always have output power !!
Could it be a defective KEY jack that is jammed? I have nothing
plugged......

Jean,
This is strange - the second case of similar behavior reported on
the reflector today. Could it be a case of the 'phase of the moon'?
When the K2 is in transmit state, the behavior will be as you
describe - no buttons operate but the K2 displays the frequency.
Check to see if your K2 is somehow stuck in transmit. The easiest
way is to check the state of the 8R and 8T voltages. You can
checkby measuring the DC voltage at the anodes of D6 and D7. During
receive, the voltage at D6 anode should be about 8 volts and the
voltage at D7 should be near zero volts. If the K2 is 'stuck in
transmit', those voltages will be reversed.
If your K2 is indeed 'stuck in transmit', try removing the key plug
and the microphone - if something external is creating that transmit
condition, it should be OK with those cables unplugged.

Hi everybody,
I have my first major trouble since my building experience back in
2004. Now, everytime i power up my K2, I can see ELECRAFT and then
the frequency..... but everything is frozen after...... still get
the frequency displayed, but no button, no function work. I also
tried to reset the K2 to the factory default by holding 4-5-6
buttons..... Got the 201 message then back to the ELECRAFT and the
frequency..... but still frozen !!!!
Is it possible the the control board PIC got a static discharge or
something like this !?!?!?!
