MFJ-557

The MFJ-557 Deluxe Code Practice Oscillator features a Morse straight key on a non-skid heavy steel base that stays put on your table. 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 along wherever you go. A volume control lets you adjust it from barely audible to blaring full sound. You can practice without bothering anyone. A tone control gives you a wide adjustment, from high squeaky' to low booming' tones. You even get an earphone jack for private listening. View larger.

When you're finished cleaning up your sloppy fists with the MFJ-557 Deluxe Code Practice Oscillator, hook the straight key to your transmitter and go on the air sounding just like you were born working QSOs. The MFJ-557 runs on a 9 volt battery (not included) or 110 VAC with optional MFJ-1312D (for units purchased after 04/28/05).
(Units purchased prior to used the earlier MFJ-1312).

Solid. 8 x 2 x 3 inches. Black. MFJ's one year limited warranty.
