The K44 is the Swiss Army knife of CW keyers, it will provide lots of CW operation and enjoyment. A CW keyboard interface, CW reader, iambic paddle keyer, backlit LCD display, and optically isolated keying outputs are all presented in one compact box. In addition, the K44 will operate many different modes including QRSS, HSCW, and conventional CW up to 140 WPM. We offer two versions, assembled and kit. Most of the K44 logic board is assembled and tested, only a small number of components have to be hand soldered on the board.

CW reader (CWR) circuitry is included on the K44 board. It accepts audio from a receiver, then filters, demodulates, and decodes CW characters which are then displayed on the LCD. The CWR provides an LED bar display that is used to tune in CW stations quickly and accurately. The K44 CWR is a new design featuring much improved copy and faster reader lock than the original K42 CWR.
