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.

Loud! Just Like She Likes It
Color: Hedgehog, Style: Big Squeak Hedgehog
My Great Dane loves this noisy toy. She prefers squeaky toys with loud, unusual squeakers. (I need to invest in earplugs.) She's not an agressuve chewer or rough player so this should last a long time. Like most squeaky toys she has, the squeaker wears out before the physical toy does and once the noise is gone she won't play with it any more. If others have a similar issue...check with your local animal shelter. Some (not all) will disinfect used toys for the dogs in their care.

Fun while it lasts…
Color: Pink, Style: Grunt Sound
Fun while it lasts. Doesn’t last very long. This is our third one and last maybe a few weeks. The part that makes noise comes detached inside which causes to toy to no longer make noise, but also can be dangerous if it comes out.

Great alternative to the grunting pigs!
Color: Pink, Style: Grunt Sound
We go through A LOT of dog toys at my dog based business. The grunting pigs are super cute, but they are also super fragile. It is incredibly easy to dislodge the squeaker. (Grunter?) These are certainly not robust chew toys, but the squeaker is about 30% better at staying put than that of the pigs. It's also smaller, so it's easier for the smaller dogs to play with. These are a new favorite! Update: August, 2024 I bought an orange hedgehog. Amazon won't let me review that separately so I had to add to my sheep review. The orange hedgehog is only 3 stars. It is made of a harder plastic than the bear and the sheep. It also has a standard squeaker, not the grunting of the bear and sheep. But harder plastic DOES NOT mean that it will withstand an aggressive chewer! If your dog likes to "kill the squeaker" they will be able to do so in minutes! This IS NOT a chew toy! If you are looking for a toy for an aggressive chewer, look at the Orbeez line from Outward Hound. The other thing that makes me less enthusiastic about the orange hedgehog is that the yellow paint started flaking off immediately. I will have to scrub it all off because it looks terrible! The dogs don't care, but their owners sure do! I haven't had that problem with the sheep or the bears. The orange hedgehog is almost like it's from a completely different company!
