<h3>CW/Morse Decoder</h3>
<p class="info-text morse-mode-help">
Decode CW (continuous wave) Morse with USB demod + Goertzel tone detection.
Start with 700 Hz tone and 200 Hz bandwidth.
Decode CW (continuous wave) Morse code. Supports HF amateur bands (USB + Goertzel tone
detection) and ISM/UHF OOK signals (AM + envelope detection).
