Yes, I read the same. Lowering the PA voltage might be a bit difficult...

Reading the display on the KPA 1500 at various RF output levels shows an efficiency as follows on 40M into a dummyload: 300W 23% 500W 27% 1000W 42% 1300W 48% 1500W 52% 1600W 54% Have other owners seen results like this? Do you think a firmware and menu item could be developed to increase the amps efficiency at lower power levels by lowering the voltage to the PA? ______________________________________________________________
