A few days ago, I implemented a CW tail tone function for the K1. Someone then asked when I would implement a full CW signal, so I quickly added it. Receiving at 650 Hz should be quite pleasing. Currently, I'm using a single-button PTT (Push-to-Talk), and the handheld microphone's PTT can also be used. It is very suitable for converting to an external direct key. Welcome to test!
