The K44 is the Swiss Army knife of CW keyers. 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 sell the K44 assembled, tested, and ready to go. A power source from 9 to 13.8 VDC is required, the K44 has a 2.1mm power jack with center plus. We sell a power supply separately for $8. Please review the cable recommendations link for K44 cabling info. We do not include a keyboard with the K44, almost any PS/2 keyboard will work fine, the User Manual provides suggestions on this.

The on board CW reader accepts audio from a receiver, then filters, demodulates, and decodes CW characters which are then displayed on the LCD. An LED array 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.
