K1EL CW Keyer – BK


Category: Tag:



The K16 is a single chip Morse code keyer with a wide range of features. It is implemented in a Microchip PIC12F1840 single chip microcontoller. A powerful keyer can be constructed using a K16 with a minimum number of components. Setup commands are directly entered on the paddles in Morse code. When not in use, the K16 will automatically enter a low power sleep mode so it can run off a battery for many months. All settings and messages are stored in nonvolitile memory so that if power is removed they are preserved. The K16 has many original features not found in other keyers. Please Note: The K16 is not pin compatible with either the K10+,K12, or K14 I.C.s
