Chelegance CQ-K557 Straight Key and Code Practice Oscillators offer a convenient solution, combining a straight key and code practice oscillator in one unit. This makes it ideal for both Morse code training as well as live radio operation. Its high-quality construction ensures precise keying and clear tones, essential for accurate operation and effective practice sessions. A CR-2032 button cell battery can be used for training, which causes the training oscillator to emit light and sound signals (battery not included). In regular operation, when connected to a radio, no battery is required.
