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 UPDATED – Training modes now support complex calls from a simple 1×1 (W1A) to a 2×3 w/ prefix or suffix (VK4AAA/VP7 or G4/W9ABC).
NEW Fox hunt mode turns the on-off-on keying into a full time key down to use with FM transmitters.
Kit comes with full instructions, further information can be found here
