I will have to disagree with that.
A 40 watt carrier with 100% modulation (sine wave audio) will produce a
120Watt PEP output, but PEP is not average. The average power that the
dummy load will see is a 50% increase.
40 watt carrier + 20 watts of sideband = 60 watts average RF power.
A similar thing is true for a thermal coupled RF amp meter. It measures
Average RF amps not Peak Envelope Amps

With 100% modulation the power could go to over 120Watts. This will take out
a 60 watt bulb...
