The emitted spectrum from a hand keyed TS-2000 on 14 MHz at reduced power, nominal 25W. The serial number is 50600050.

Keying waveform from a hand keyed TS-2000 on 14 MHz at reduced power, nominal 25W. This is the first key-down transition. Note that the ALC is not quite fast enough for the amount of gain reduction needed. There is a strongly damped oscillation with a period of about 0.4 ms (2.5 kHz.) The overshoot, is about 1.5 dB (40% in power) The serial number is 50600050.

Keying waveform from a hand keyed TS-2000 on 14 MHz at reduced power, nominal 25W. This is the second key-down transition in a string of dots. At reduced power the ALC recovers fast enough to affect each key down transition at normal hand keying speeds. This is because the gain reduction that the ALC has to produce is large. The consequence is keying clicks as can be seen in the spectrum. At full power the keying is very good - if you use this rig with a power amplifier, run it at full power and use an attenuator to reduce the drive level if your power amplifier needs less power. A run of lossy (thin) coaxial cable can be used as an attenuator. Another alternative is to reduce tx gain with a fixed DC voltage on the ALC input. The serial number is 50600050.
