Practice amateur radio CW QSOs with realistic simulations. Choose from 599BK, Rubber Stamp, or Contest styles. Adjust call signs, signal levels, and CW speeds. Simulate pile-ups with up to three stations. Set own station parameters for CQ calls.
Simulate amateur radio QSOs with realistic call signs and signal levels. Adjust CW speed and set own station parameters. Support pile-up with up to 3 simultaneous stations. Include 599BK, Rubber Stamp, and contest-style QSOs.
Access the periodic table with atomic weight, electronegativity, electron affinity, ionization energy, radius, and isotopes. Compare element properties. Search for compounds and reactions. View chemical equations and formulas.
Udio tones across 20 Hz to 20 kHz for testing, tuning, or experimentation. Test speaker performance for distortion or imbalance. Clean muffled speakers using the built-in speaker cleaner tool.
Analyzes device motion using accelerometers and gyroscope. Displays time series data and frequency spectra via FFT. Supports external USB accelerometer. Applies Hamming window and removes DC bias. Tracks three-axis movement with 0.02g sensitivity.
