Users can send Morse code via keyboard, with support for 10 predefined text memories and macros for common phrases like "CQ" or operator details. Setup and Hardware Integration
Features built-in filters (typically 30Hz), Smart AFC (Automatic Frequency Control) to track drifting signals, and Smart AGC (Automatic Gain Control) to compensate for fading. mrp40 morse decoder

MRP40 is distinctively capable of decoding signals that are barely audible to the human ear. Because the FFT isolates the signal by frequency, a signal with a very low SNR (Signal-to-Noise Ratio) can be visualized on the waterfall display before it is audible. If the noise is "white" (evenly distributed) and the signal frequency is stable, MRP40 can often copy text successfully. A MAN WILL SEND AN SOS IN 12 MINUTES
The screen cleared. New text crawled across:
He didn't sleep that night. He traced circuit diagrams, ran diagnostic loops, even disconnected the antenna. Nothing. The MRP40 sat inert, its amber glow steady but silent. Only when he reconnected the feedline at 3:16 AM did the decoder wake—not with a signal, but with a memory.
