Ham speak here. QRP == Low Power (Approximately 2W), CW = Continuous Wave aka Morse Code. And a Transceiver is a device that can both transmit and receive.
I love how w2aew (Alan Wolke) shows the block diagram, explains it and then runs through the schematic for the MFJ Cub 40m explaining the functions of the components. Pretty cool.
Thanks a lot Alan!
