Before the audio even reaches your computer, use your transceiver’s IF filter or narrow CW filter (e.g., 500 Hz or 250 Hz) to eliminate strong adjacent signals.
Plug one end of the audio cable into your radio’s audio output and the other into your computer’s audio input jack.

The Memory Bank is a double-edged sword. When receiving a rare DX station sending "TEST BK," MRP40 might incorrectly guess "TEST BE" if 80% of prior traffic used "BE." This feature should be disabled for logging new prefixes.
: Features Smart AGC (Automatic Gain Control) to compensate for fading and intermodulation . Before the audio even reaches your computer, use
Tune your receiver to a active CW portion of the band (e.g., 7.000–7.040 MHz on 40 meters).
MRP40 is .
: It includes an extremely selective built-in filter with a bandwidth as narrow as 30Hz, which dynamically adapts to the speed of the incoming signal to isolate it from noise.
For amateur radio operators, shortwave listeners (SWLs), and CW (Continuous Wave) enthusiasts, copying Morse code by ear is a rewarding skill. However, when signals fade, interference rises, or operators send at blistering speeds, having a reliable software assistant makes a massive difference. The Memory Bank is a double-edged sword
