FLDIGI is the most common free alternative. It is an incredible Swiss-army-knife for digital modes. However, in head-to-head "weak signal" tests, MRP40 almost always recovers more clean text from the noise than FLDIGI’s CW module.
Buy it if you struggle to copy weak CW. Borrow it if you’re chasing rare DX. Ignore it only if you already have golden ears.

(e.g., USB cable, audio interface, or acoustic coupling)
