Features
From observing a signal to reanalysing a recording, reception controls stay close at hand.
Tune on the spectrum
Click or drag the FFT to tune. Arrow keys adjust by 1 Hz, or 10 Hz with Shift. Home returns to 17.200 kHz.
Listen at an audible tone
Convert the signal near 17.2 kHz to a CW tone from 400 to 1000 Hz. Select Audio IN and OUT independently.
Bandwidth and noise reduction
Choose 50 / 100 / 220 / 500 / 1000 Hz bandwidth. Simple NR offers OFF / weak / medium / strong and affects monitor audio only.
CW decoding assistance
Use automatic speed tracking or a manual 5–40 WPM setting. Decoding is experimental and may be incorrect with noise or weak signals.
Record and analyse raw input
Save input PCM before DSP processing as WAV. Reanalyse 48 kHz, 16-bit PCM WAV using the selected frequency and bandwidth.
Keep your reception data
Recordings go to recdata and decoded text to masterdata. Settings are restored on the next launch.
Operate in three languages
Japanese, English and Russian are available, with immediate switching in the application’s Language menu.
