Spectrum of a FT-1000D when hand keyed on 14 MHz at full power (200W)
The serial number of the unit is 3G330126
Narrow range spectrum of a FT-1000D when hand keyed on 14 MHz at full power (200W)
The serial number of the unit is 3G330126
Time domain plot of key-down transition of a FT-1000D.
The oscillation occurs because the rise time that is formed by
passing the keyed waveform through a filter is modulated by keying
with a similar rise time in a subsequent stage.
The serial number of the unit is 3G330126
