The for code comes from for K3NG, and it’s an open source code so you can fully customize it to fit your needs and also perhaps learn from it or find coding ideas for other projects. We redesigned the PCB, which could be fit into a compact aluminum enclosure, and trimmed the code so as to fit the features of AVR for mega 2560. The Funtronics K3NG Keyer integrates nearly all of the features and functions of the K3NG’s code, such as LCD display, USB keyboard, encoder and CW decoder etc. Moreover, there are some spare IOs left on the pcb, which could be left for the feature new features and functions. Winkey Emulation: The for K3NG keyer supports winkey 1.0 and 2.0 emulation, and it is compatible with many contest and logging softwares. The following functions are currently implemented in the emulation: Currently the following functions are implemented: CW Sending (of course) Pause Key Down Unbuffered and Buffer Speed Setting Iambic A and B, Mode Settings Ultimatic in normal, dit priority, and dah priority modes Farnsworth Pointer Operations Backspace Sidetone Frequency Settings (Winkey 1, 2, and custom frequencies) Paddle Reverse Paddle Watchdog Keying Compensation Dit to Dah Ratio Contest Wordspace Autospace PTT, Tail, and Time Speed Pot Setup and Query First Extension Software Paddle Weighting HSCW Serial Echoback Prosigns Dual transmitter keying lines Paddle Only Sidetone Memory button reporting Standalone Message Sending
