Spectrum of a hand keyed Orion on 14 MHz at full power (100W).
The serial number is 03C10433.
Spectrum of a hand keyed Orion on 14 MHz at reduced power (10W).
The serial number is 03C10433.
Spectrum of an Orion on 14 MHz keyed with dots at 50wpm at full power (100W).
The serial number is 03C10433.
Time domain plot of amplitude and instantaneous frequency for the
first key-down of an Orion at full power.
The ALC destroys the raised sine waveform and causes severe keying clicks.
The serial number is 03C10433.
Time domain plot of amplitude and instantaneous frequency for a
steady state key-down of an Orion keyed with dots at 50wpm at full power.
The keying clicks are present even on close spaced dots because the
ALC release time is far too fast. (Typical for amateur radio transceivers)
The serial number is 03C10433.
Time domain plot of amplitude and instantaneous frequency for a
key-up of an Orion.
The key-up transmission is a raised cosine.
It is not affected by the ALC, but something is wrong at low levels
where the phase is modulated.
The serial number is 03C10433.
Time domain plot of amplitude and instantaneous frequency for a
key-up of an Orion.
Same as previous image, but with more gain for the amplitude.
Besides the phase modulation there is an abrupt amplitude
modulation just before the signal disappears.
The serial number is 03C10433.
