CW Keyer:
This is a 2-in-1 CW keyer that can be used as a keyer or a key trainer. When used as a key trainer, it supports both manual and automatic keys.
Features:
1. It is about the size of an ordinary eraser, but thinner. Its extremely small size makes it extremely portable, and it can be slipped into a pencil case, school bag, briefcase, key box, or even a pocket. Considering that most people who need to carry it often carry QRP radios and keys, its size is almost negligible compared to these items. It doesn't take up much space when in use. As long as there's somewhere to put QRP radios and keys, it will find a place, which also makes it more flexible for enthusiasts to choose where to place it.
2. It requires only a CR2032 battery for power; no external power supply is needed, and it is free from the limitations of a power cord, further reducing its dependence on desk space and expanding its application scenarios. When used as a keyer with a QRP radio in the field, no additional power supply is required. With the keyer and a CR2032 battery, your QRP radio without a built-in keyer function can support automatic keying. The CR2032 is a very common battery model that can be easily purchased in any supermarket or even a convenience store. One battery can be used continuously for several months, making it energy-efficient and environmentally friendly.
3. Multiple functions give CW unlimited possibilities. This keyer can also be used as a training device during normal operating hours. It supports hand keys for vertical operation, sweep keys and mechanical semi-automatic keys for horizontal operation, as well as other forms of manual electric keys. It also supports all forms of automatic electric keys. It makes no compromises with any electric keying method. No matter what type of operating method you use, it can be easily mastered with this keyer. When used as a keyer, it can support automatic keying for your QRP radio without a built-in keyer. Whether it's a single paddle or a double paddle, it's plug-and-play. The advantage of automatic keys also makes your operation more efficient.
4. Practical and easy to use, simple to set up. When used as a training device, the manual key and automatic key simply need to be connected to their respective interfaces; when used as a key controller, the automatic key is connected to its corresponding interface and the radio to the output/manual key interface. In automatic key training device and key controller modes, flip the toggle switch to switch between the left and right sides of the dot and dash. Press the speed button and the dot button of the automatic key to increase the key controller speed, and press the dash button of the automatic key to decrease the key controller speed.
5. Whether used as a training device or for key control, not only does the buzzer sound, but the blue LED light also flashes in rhythm, and sound and light follow the rhythm, making it easy to control the rhythm.For beginners: When used as a manual keyboard practice device, whether with recordings or on its own, the dual auditory and visual cues help deepen understanding of the rhythm, correct technical errors in time, and avoid QSD (bad hands) during practice. For veterans, daily practice not only doesn't require larger radios or traditional practice equipment, but it also allows for the visualization of one's own rhythm. CW is both a language art and a musical art. Every rhythm has a unique personal style that is more pleasing to the eye after being visualized by the striking blue LED lights.
