MFJ-557 Description
Hide
The MFJ-557 Deluxe Morse Code Practice Oscillator features a Morse Code straight key on a non-skid heavy steel base -- it stays put on table and doesnt move around while youre sending! The MFJ-557 lets you practice sending code at home, work, riding in your car -- practically anywhere -- because it's so easy to take it wherever you go. Volume control adjusts from barely audible to blaring full sound. You can practice without bothering anyone. Tone control gives you a wide adjustment from high "squeaky" to low "booming" tones. You even get an earphone jack for private listening. You can plug in an external speaker for super high volume in the classroom.
