U20616 Never Used MFJ Econo Keyer II with Memory MFJ-401E

U20616 Used MFJ Econo Keyer II with Memory MFJ-401E

This MFJ-401E Econo Keyer II with Memory is in unopened, factory condition inside its original white retail box. The outer carton is clean with negligible shelf handling marks. It is ready to drop straight into your CW operating desk or portable field-day go-box.

The MFJ-401E is a compact, full-featured iambic memory keyer designed to bring effortless Morse code sending to any transceiver—especially older rigs or QRP radios without built-in electronic keyers. Equipped with four non-volatile message memories, smooth front-panel speed, volume, and pitch controls, and selectable Iambic A/B modes, it delivers crisp, accurate CW from 8 to 50 WPM. Complete with a built-in sidetone speaker, adjustable weighting, and universal solid-state keying outputs for both positive and negative keyed transceivers, this keyer is a great way to add smooth iambic keying and convenient message playback to your station.
