The IK-440 Instructokeyer provides an infinite variety of code groups allowing unlimited practice for higher proficiency. In addition, the IK-440 is a state-of-the-art keyer which uses the new 8043 keyer-on-a-chip IC. It uses no motors or tapes.
The all solid-state unit sends random groups of Morse letters, numbers, punctuation and word spaces in an ever changing sequence which never exactly repeats.
Code speed is adjustable from 4 to 50 wpm. Code groups are of varying lengths but average five characters per group. A rear panel switch selects alphabet only or full alphanumeric.
The keyer portion of the IK-440 provides self-completing dots, dashes and spaces, instant start, dot memory, weight control, iambic mode and built in sidetone.
Front panel controls are provided for volume, pitch, weight, speed, on-off, tune, self-test and "keyer/code practice." The IK-440 will key +300 VDC at 200 mA in either the keyer or code practice mode. Output switching is solid state.
