K16 Keyer IC

Microchip continues to offer higher functionality in their PIC microcontrollers which allows us to offer better and better keyer ICs. Our latest keyer is the K16 and it is available now. This is our 16th year selling keyer ICs and we have implemented a list of "please add this" requests as well as things that no other keyer chip offers. The K16 has non-volatile EEPROM memory, when you remove power it retains messages and settings. Twelve memory slots are provided along with many new embedded commands. In addition to HSCW support the K16 provides QRSS for VLF beacon work. Note that the K16 is not pin compatible with previous K1EL keyer ICs.
