Spectrum of a continuous carrier from a FT817 on 144 MHz at full power (5 W). The serial number is 1D240059.



Spectrum of a continuous carrier from another FT817 on 144 MHz at full power (5W). The serial number is 1E270433.



Spectrum of a continuous carrier from a FT817 on 14 MHz at full power (5W). The serial number is 1E270433.



Spectrum of a continuous carrier from a FT817 on 144 MHz at minimum power (0.5 W according to the front panel setting). The serial number is 1D240059. The ALC is self-oscillating with small pulses repeating at about 1 kHz. This instability in the ALC loop has a pronounced effect on the spectrum of modulated signals from the FT-817.
