Mini-Yack (Yet Another CW Keyer) is the bare bones little brother of the 3CPO keyer and iambic trainer designed for embedding into a QRP radio. Included within the YACK engine are 2 memories, a beacon mode and 2 Iambic training modes.
NEW Advanced Iambic Training Mode – Is it a training or is it a challenging game? The new advanced Iambic training mode will send a call sign which must be properly re-entered with Iambic paddles. On each successful entry the keyer will advanced in speed by 1WPM and on each wrong entry will decrease by 1WPM. When training is complete (by pressing the COMMAND button) the keyer will return to the default speed and send what the last speed during the session, the number of calls entered correctly and the total number of calls sent.
