Now let’s have a look at the rise in temperature of the different parts when the TS-480HX transmits
continuously (14MHz) for 30 minutes at 200W. To provide a comparison, plotted on the same
graph is test data compiled for a compact 100W model (designed so as not to power-down during
continuous transmission at 100W).
