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.

PROFOUND
Format: Paperback
Mesmerizing, profound, even for a study machine such as myself. Cal Newport, a college student himself, wrote these books after interviewing extraordinary students around the country who had straight A's, full social lives, and did lots of extracurriculars such as starting businesses & non-profits, and being politically involved. The point of all his books is how to study more efficiently so you can be an outstanding student while fitting in other essential dimensions of the college experience such as friends, parties and guest lectures. And unlike "speed reading," his techniques are not smoke and mirrors; they are solid and make sense. I didn't feel there was much overlap between his books. "How to Win at College" is composed of 75 two-page "tips" that cover a very wide range of topics. This is the book I originally fell in love with and ordered copies of for many friends, and I recommend reading it first. His second book, "How to Become a Straight A Student," focuses on a few key skills: the trap of "pseudo-studying," time management, how to actually study, conquer exams, and write papers. However once I read it, I liked it almost better than the first one! In short, they are both indespensible, easy reads, hard to put down, and completely different from any other "study skills" books you might read. They are basically "myth busters" of conventional wisdom about school success. If you want to know the "secrets of the universe" regarding succeeding in and loving college, look no further.

70% practical advice, 15% feel-good advice, 1% useless advice, 14% advice that saved my academic life
Format: Paperback
To be honest, if I had just graduated high school and someone gave me this book as a gift, I would roll my eyes and never open it. I picked it up a week ago, however, now that I am almost done with my second year of university, and I really do wish that I had had it (and cared to read it) two years ago. The book is seventy-five pieces of advice, each with about two pages of explanation. The advice is pretty simple, as you can see from looking at the table of contents ("Dress Nicely for Class," "Never Nap," "Eat Healthy," "Always Go to Class"). But the reason this book is effective is that it serves as a quick-reference manifesto for some of the more important (to me) advice. For example, I'm taking a grad-level fiction writing class. No due dates (except the final deadline at the end of the semester) and no class. You just write at your own pace and turn in a portfolio. This is incredibly difficult for me to do, and I'm unbelievably far behind in the work for the class. I was really quite worried about how I would ever pull it off. The whole semester, my fiction work has been priority #75, and I usually crash between priorities #14 and #20. But with some of the advice in this book ("Keep a Work Progress Journal," "Set Arbitrary Deadlines," "Avoid Daily To-Do Lists," "Don't Take Breaks Between Classes"), I actually feel pretty confident about being able to finish on time. By reading this book (and [...] and Newport's more recent book, ) I've adopted some strategies and habits that have actually yielded results. Before Cal Newport, I was up late every night, angrily doing my homework until I couldn't drink any more tea, without any free time. Now, I'm getting my homework done before sundown (for the most part), feeling enormously more relaxed, and regaining a good amount of the excitement that I had about college before I got here. If you're on your way to college, and you're the sort of person who can stomach (and listen to) advice, do yourself a favor and read this book. Newport admits in the introduction that not every piece of advice will be for you (for me: "Exercise Five Days a Week" and "Use a Filing Cabinet"). If you want to be more than an average student without being a "grind," this book has a good deal of solid advice. If you're already in college, and you're looking for more in-depth and practical advice, I recommend also reading . It has more thorough advice for confronting the terrors that you have come to know in college.

Will Help You Reach the Goal You Thought You Could Never Achieve
Format: Paperback
Quick review: if you're about to go into college, BUY THIS. If you're already in college, STILL BUY THIS. This great book has conventional and unconventional advice. I'm already a fan of Cal Newport's advice and blog, but this book condenses his ideas that are most relevant to me (since I will be going to college in the fall of '15). It isn't a typical 'how to do well in college' book whatsoever. This truly gives you the truth of what needs to happen to become a part of the exceptional. And he isn't writing it with the assumed purpose of impressing everybody or becoming a mega-successful overlord; he writes with the tone that leaves up the ultimate goals you have up to you. Also, the writing style is not annoying like a lot of books are. Personally, I just want to optimize my college experience, leave my comfort zone, and get into grad school. This book will help me. If you want to start the track of becoming a super-rich, art-gallery-going, Bentley-driving, awe-inspiring successful person, this book will still be very worth your time. It's absolutely worth the money if that's what is keeping you on the edge of buying this. It has countless (actually 75) useful ideas throughout, too, if you worry it has only one or two pieces of useful advice and that's it. Bonus: if you like what you read, he has a blog with even more stuff to learn.

Fantastic Advice
Format: Paperback
I'm a senior in high school preparing for my freshman year. This book is amazing. The advice is down to earth and believable without being preachy or perfect. Newport is perfectly willing to admit that things aren't always going to go exactly as planned, but still tells his readers how to accomplish great things. I absolutely loved the advice. Some of the advice in this book is not for everyone - APPLY TO TEN SCHOLARSHIPS A YEAR can be overwhelming and unnecessary, depending on the student. That said, it's easy to see how even applying a handful of these tips would change my college career for the better. As a student who will have to balance work, class, and a social life, I think this will be rewarding. Here are a handful of my favorite tips: CREATE A SUNDAY RITUAL STUDY IN FIFTY MINUTE CHUNKS USE THREE DAYS TO WRITE A PAPER EAT HEALTHY VOLUNTEER QUIETLY And the list goes on. I will definitely pack this with me in the fall.
