If your radio is equipped with the KDSP2, check the settings. I must have been

On the bottom of the RF Board, check the small RF Choke RFC15 for
continuity - check with the ohmmeter, voltage checks at both ends will
be 5 volts even if it is open. If it is open, you can use a temporary
jumper across it, but get the proper choke and install it when available.

I recently built a BL-2 Balun. It is connected between my Palstar AT1KM

Balun heating is normally caused by attempting to feed a very high or
very low impedance.
Have you tried the 4:1 position? It may help, so do try it even though
I would believe the antenna system feedpoint impedance where the balun
is connected may be in the range of thousands of ohms
Gary,
What frequency of operation causes the balun overheating? Assuming the

line length if you favor that band of operation.
For example, when using a 100 ft. dipole at 3.8 MHz and 1/4-wave in height

I believe the BL-2 is rated at 150 watts so running at 125W is already
at the limit even when it is placed in the ideal point in the circuit

Yes, you are reaching the curie temperature of the core. At that point
it's magnetic properties change dramatically.
Of course that heat comes from RF that is becoming heat instead of being

losing the same amount of power
