The K42 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 K42 will operate many different modes including QRSS, HSCW, and conventional CW up to 140 WPM.
CW reader (CWR) circuitry is included on the K42 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.
