Hi Jim es all,here are two dummy loads in use; one is a bulb 110V/DC500W, Z 35 Ohm on 136kHz (bridge measurement) and the other is made of four hollow ceramic resistors 200 Ohm/60W each, makes 200W only. but blowing air through the resistors (see attachment) makes a lukewarm 300W dummy on 136kHz (0,4uH only). I tried 800W. A peace of paper above the dummy caught fire within 10 sec. regards Uwe/dj8wx
