Relax and place this tiny pocket size portable MFJ Morse Code / CW Reader near your receivers speaker. Then watch Morse code signals turn into solid text messages as they scroll across an easy-to-read LCD display. No cables to hook-up, no computer, no interface, no other equipment needed! Use it as a backup in case you miscopy a few characters. It makes working high speed CW a breeze -- even if youre rusty. Practice by copying alone with the MFJ-461.
