PS
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
... (50 ohms resistive). Place it in a point in the circuit where the
resistance varies up or down from the ideal of 50 ohms and then make it
complex with added reactance and the unit could make like a toaster
element. Of course if you operate QRP you will be just fine as long as you
tolerate the RF power loss in the balun. Just imagine trying to make the
circuit work at 1KW. Nothing like power to illustrate weakness.
