MFJ-407E – Deluxe Curtis Keyer w/Memory – Everything you need to send great CWfrom this MFJ Cutris Keyer TM — easy access front panel controls, all keyer modes, dot-dash memories, jam-proof spacing, weight control, sidetone, built-in speaker and more.

Speed, weight, tone and volumecontrols, and tune, semi-auto and on/off switches are on the front panel.

A dual paddle key such as the MFJ-564, lets you use the iambic mode. In this mode, you can insert a dot before a dash finishes or insert a dash before a dot finishes. Also, squeezing both paddles generates alternating dots and dashes. This lets you send characters such as C, K, and R with a single squeeze. It turns an inexperienced fist into a professional. You can use the automatic mode with a single or dual paddle. You automatically generate dots and dashes by pressing the paddle. You can switch into a semi-automatic bug mode to generate dots automatically and dashes manually. Or you can use a straight key and manually generate your own dots and dashes. You get dot-dash memory, self-completing dots and dashes, jam-proof spacing and instant start keying. Select Type Aor Type B keying to match your sending style. Weight control lets you adjust your dot-dash space ratio to make your signal sound distinctive to bust through pile-ups. It also lets you compensate for the turn-on delay of your transmitter.
