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.

WEIRD feature - requires a water bottle
Color: Cow, Size: Large
Cute, but buyer beware. Maybe the description said this, but who would think to read for this.... You have to insert an empty bottle (like an old water bottle) for it to make the crinkle noise. There is a velcro spot at the base where you can open it and insert the water bottle for the noise factor and your dogs entertainment. I've yet to do that, but feel like my dog is gonna figure out the velcro and get the bottle out in no time. Seems like a waste of money. I could just give her an empty water bottle without the toy for free.

Best dog toy!
Color: Multicolor/Alligator & Wild Duck, Size: Medium, Color: Multicolor/Alligator & Wild Duck, Size: Medium
Best dog toy! Most dog toys lady maybe a week or less but this one has been going strong for almost 2 months. Both the squeekers still work on both toys i purchased. My vizsla loves ti squeek and carry it around. We added an empty water bottle in the pocket cavity for some extra fun! Yes, we are still on the same water bottle! Fantastic durability.

Shows wear quickly
Color: Multicolor/Sheep & Cow, Size: Medium
These are cute but not holding up as well as I had hoped. Quality is ok and the Velcro has held up great. The fabric just isn’t as good as it could be. They are much larger than expected.

Super Sturdy with hours of fun.
Color: Wild Duck, Hare, Squirrel & Alligator, Size: Small
I got the small ones that you cannot put a water bottle in. These toys have held up way better than expected. I am dog sitting a very rough with toys dog named Chunk. He tears up ever. Single. Toy my dog (Ted) has. I bought new ones just for chunk. These appealed to me with the no stuffing, They were cheaper, and have a squeaker. Everything chunk needed. They arrived on time and I thought I wasted my money. They were super soft, like too soft. They felt flimsy and weak. Like 5 minutes with chunk and they be dead. 2 hours with my dog and they would have a rip. So far 2 of them (I set two out) have lasted the whole weekend. The bunny looks very rough and disgusting, but no rips, the squeakers still work, and no random fluff everywhere. I am going to wash the bunny once chunk leaves. My very careful doggo Ted loves them too. He throws them up in the air and catches them, plays tug of war with them, and no rips. They are super sturdy. He can’t wait until Chunk leaves (chunk is 2 and Ted is 12-13) so he can play with them.

Loved it
Color: Brown/Wild Duck, Size: Large, Color: Brown/Wild Duck, Size: Large
He loved it so much, he destroyed it so we ordered another. I didn't realize that you can stick an empty water bottle inside. Again, the first one didn't last long, but he enjoyed it
