K1EL Systems LLC
The K45 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 K45 will operate many different modes including RTTY transmit, QRSS, HSCW, and conventional CW up to 99 WPM. We sell the K45 assembled, tested, and ready to go. It is powered over a USB cable connection to a PC, charger, or battery. Please review the cable recommendations link for K45 cabling info. We do not include a keyboard with the K45, almost any USB keyboard, wired or wireless, will work fine.

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 bar graph is used to tune in CW stations quickly and accurately. The K45 CWR is a new design featuring much improved copy and faster reader lock than the original K42 CWR.
