Current K12 Revision is D
K12 Features

The K12 replaces the very popular K10 and K10+ keyers which have been shipping for almost ten years now. The K12 shares the same pinout with the K10's so you can easily upgrade your existing keyer and enjoy some great enhancements. The new K12 has non-volatile EEPROM memory, when you remove power it retains messages and settings ! No more keep alive battery. Six memory slots are supported along with many new embedded commands. In addition to HSCW support the K12 provides QRSS for VLF beacon work. The K12 I.C., as well as a K12 kit, is in stock for immediate delivery. The chip cost is $6 and the kit cost is $17 for either the battery version or externally powered version.

K12 Keyer Kits - No Longer Available, they have been replaced by the K16

The K12-BAT Kit is for standalone applications where external power is not available. Since the idle current of the K12 is so low a CR2032 coin cell can last up to one year.

Both kits include the K12 chip, PCB, and all board mounted components as shown.
Board Dimensions: 2.0" by 1.6"

The K12-EXT Kit is for applications where the keyer board will be incorporated into a radio or other device where 6 to 16 volt power is available. An on board regulator is included.

K12 I.C. - $6 USD
