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.
