About This Software

JT65-HF software implements the JT65 digital mode, which was originally developed for meteor scatter communication but has become popular for weak signal work on HF bands. The software uses narrowband transmission and sophisticated error correction to decode signals that are buried deep in the noise floor. Compatible with most standard ham radio interfaces, it provides real-time decoding, logging, and automatic message generation. The software is particularly valuable during poor propagation conditions when traditional modes fail.
