internet-cw-sine-wave

Figure 1: Sine wave signal shape.

Figure 1 shows two signal components of the sine wave tone that picoFrog internet cw tone generator makes.

1. When you press the key, the sine wave tone gradually fades in.
2. Then, the signal continues as a standard sine wave as long as your key is pressed.

Tone level and frequency

With the left potentiometer you can change the tone frequency and find the perfect one for you. The right potentiometer controls the tone level.

Input: electronic keyer or straight key

Your keying device can be a straight telegraph key or an electronic keyer. Second 3.5mm socket will accept either of them.

Automatic turn OFF

If you forget to turn OFF the device, it can work for hours wasting battery power for nothing.

Because of this, we added a special feature – NO manual turn OFF.

After four minutes of telegraph key inactivity, picoFrog internet cw tone generator will automatically shut itself OFF.
