Get everything you need to send beautiful CW from this Deluxe MFJ Curtis Keyer -- 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 volume controls, and tune, semi-auto and on/off switches are on the front panel.
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.
Has tune switch for tuning your transmitter or antenna tuner. RF proof. Built-in speaker for sidetone. Keys solid state and tube transmitters. Use 9 volt battery or 110 VAC with MFJ-1312D
