The MFJ-401E Econo Keyer II is a microprocessor-controlled keyer that provides iambic key operation and dot-and-dash memory to make sending perfect code easier. It has tunable code speed, code weight, and sidetone frequency; it supports both direct and grid-block keying outputs. You also get to choose between Iambic Type “A” and Type “B” keying.

Plugging in 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 a 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 A or type B keying to match your sending style. Weight control lets you adjust your dot dash space ratio to make your signal distinctive to bust through pile-ups. It also lets you compensate for the turn-on delay of your transmitter.
