Introduction  

 

The K45 is the latest member of the K1EL CW Keyboard product line which started with the K20 in 1997. It 
incorporates a CW reader and has both USB keyboard and USB host interfaces. Two separate CW output 
ports are provided that can key almost any transmitter. Due to part availability issues, the K45’s logic board 
was recently redesigned and is now at revision B. With the exception of a different USB interface IC 
(CH340) the revision B board is functionally equivalent to the revision A board.  
 
The K45 is housed in an all-metal chassis with a four line by twenty-character LCD display. A slanted face 
on the K45 enclosure presents the display for comfortable viewing. A rotary encoder with a push switch 
provides user input. The unit is powered by connection to a USB power source, this can be a USB charger, 
USB battery, or the USB port on a PC or laptop. The K45 draws low current, about 150 mA, so a standard  
phone charger will work fine.

provides the user with many viewing options. 
 

Status Line 

The top line of the display is used for status feedback to the user.
