nanoKeyer USB CW contest keyer
Arduino Nano-based CW contest keyer with K3NG firmware and K1EL Winkeyer compatibility
Description
The nanoKeyer is an Arduino Nano-based CW contest keyer, specifically designed for use with the K3NG Arduino keyer open-source firmware. It supports CW speeds from 1 to 999 WPM and emulates the K1EL Winkeyer interface protocol, making it compatible with major logging applications such as N1MM and HRD via its USB port. The device also features SO2R compatibility through K1EL Winkeyer 2 protocol emulation.
Keyer functionalities include a command mode for settings adjustment, up to 12 memories with macro and serial number support, QRSS and HSCW modes, and Iambic A and B, Ultimatic, and Bug keying. It also offers Farnsworth Timing, Autospace, Wordspace Adjustment, Keying Compensation, Dah to Dit Ratio, and Weighting adjustment, with most settings stored in non-volatile memory.
The nanoKeyer includes one optically isolated radio port for PTT and CW keying, a standard 6.3mm stereo jack for paddle connection, and a mini DIN jack for a PS2 keyboard for computerless operation. It can be powered via USB or an external battery/power supply.
