Product Description
Morse Code CW Transmission Training Key Sound And Light Circuit Board Suitable For Manual KeyFeatures:
1. The size is comparable to that of an ordinary eraser, but the thickness is thinner than that of an eraser. Its extremely small size makes it extremely portable, and it can be put into a pencil case, school bag, briefcase, keypad box, or even a pocket. Considering that most people who need to carry it out often carry a keypad, its size is almost negligible compared to the keypad. It does not take up too much space when in use, and it can be placed wherever a keypad can be placed, which makes it more flexible for enthusiasts to choose the place of use.
2. It only needs one CR2032 battery for power supply, and no external power supply is required. It is free from the constraints of the power cord, further reducing the dependence on desktop space and broadening the use scenarios. CR2032 is a very common battery model, which can be easily purchased in any supermarket or even a convenience store. One battery can be used for several months, which is energy-saving and environmentally friendly.
3. When operating, not only the buzzer will sound, but the green LED light will also light up with the rhythm, and the sound and light will follow the rhythm, making it easy to control the rhythm. For beginners, whether they practice following recordings or practicing by themselves, the dual cues of hearing and vision help deepen their understanding of rhythm, correct mistakes in technique in time, and prevent QSD (bad hands) from being practiced. For veterans, daily practice not only eliminates the need to rely on larger radios or traditional practice devices, but also allows them to visualize their own rhythm. CW is a language art as well as a musical art. Everyone's rhythm has a unique personal style. After being visualized by the eye-catching green LED light, everyone's rhythm style is more pleasing to the eye.
4. It supports vertical hand keys for vertical operation and sweep keys and mechanical semi-automatic keys for horizontal left and right operation. Other forms of manual electric keys are also made in one "device", without compromising with any manual electric keys. No matter what the operation method is, it can be easily mastered with the help of this practice device.
