I took a quick look this morning. I keyed the Corsair at 30wpm, fast
QSK, and 100W output into a dummy load. I tried 50kHz and 200kHz
frequency splits. I listened to the signal on a monitor receiver and
viewed the RF output envelope on a scope.
I heard no sign of chirps or clicks. The output waveform looked perfect
- no overshoot, and smooth 4-5mSec rise and fall times.
