Hand Key Oscillator Automatic Key Trainer Automatic Key Controller Can Adjust The Transmission Speed

CW keyer:
This is a two-in-one CW keyer that can be used as a keyer or a key trainer. When used as a key trainer, it supports both hand and automatic keys.

Features:
1. It is about the same size as an ordinary eraser, but thinner than an eraser. Its extremely small size makes it extremely portable, and it can be put in a pencil case, school bag, briefcase, key box, or even a pocket. Considering that most people who need to carry it out often carry QRP radios and keys, its size is almost negligible compared to QRP radios and keys. It will not take up too much space when in use. As long as there is a place where QRP radios and keys can be placed, it has a place, which also makes it more arbitrary for enthusiasts to choose the place of use.
2. It only needs a CR2032 battery for power supply, no external power supply is required, and it is free from the constraints of the power cord, which further reduces the dependence on desktop space and broadens the use scenarios. When used as a keyer with a QRP radio in outdoor operation, there is no need to carry an additional power supply. The keyer plus a CR2032 battery can make your QRP radio without a keyer function support automatic keying. 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 continuously for several months, which is energy-saving and environmentally friendly.
3. Multiple functions give CW unlimited possibilities. This keyer can also be used as a practice device at ordinary times. It supports hand keys for vertical operation, sweep keys and mechanical semi-automatic keys for horizontal operation, and other forms of manual electric keys. It also supports all forms of automatic electric keys. It does not compromise with any electric key. No matter what kind of operation method, it can be easily mastered with the help of this keyer. When used as a keyer, it can support automatic keying operation for your QRP radio without a built-in keyer. Whether it is a single paddle or a double paddle, it is plug-and-play. The blessing of automatic keying will also make your operation more efficient.
4. Convenient and easy to use, simple to set up. When used as a practice device, the manual key and the automatic key only need to be connected to the corresponding interfaces respectively; when used as a key controller, the automatic key is connected to the corresponding interface, and the radio is connected to the output/manual key interface. In the automatic key practice device and key controller mode, flip the flip switch to switch the left and right of the dot and stroke. Press the speed button and press the dot of the automatic key to increase the key controller speed, and press the stroke of the automatic key to reduce the key controller speed.
5. Whether used as a practice device or a key controller, not only will the buzzer sound, but the blue 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, when used as a manual key practice device, whether it is practicing with recordings or practicing by yourself, the dual cues of hearing and vision help to deepen the understanding of rhythm, correct the mistakes in technique in time, and prevent QSD (bad hands) from being practiced. For veterans, daily practice not only does not rely on larger radios or traditional practice devices, but also allows their own rhythm to be visualized. CW is a language art as well as a musical art. Everyone’s rhythm has a unique personal style, which is more pleasing to the eye after being visualized by the eye-catching blue LED lights.

Comfy and perfect heels for the summer!
Love these heels! I’m 5’5”, 120 lbs and size 8.5. They were comfortable from the moment I put them on and I have somewhat wide feet. They are the perfect summer heels!

Cute but Extremely Uncomfortable
Size: 6, Color: Blue Leather
The shoes are very pretty, but they are absolutely uncomfortable. I could barely wear them for an hour without my feet hurting. Unfortunately, they look much better than they feel. I really wanted to love them, but they are not comfortable enough to wear for any extended period of time.

Too narrow at the toe. I have narrow feet, but I could feel my toes being squished as soon as I stood up in these.. Bummer.
