Fldigi v4.1.21 now available

The development team led by W1HKJ have announced the release of Fldigi v4.1.21.

Fldigi is a modem program for most of the digital modes used by radio amateurs today: CW, PSK, MFSK, RTTY, Hell, DominoEX, Olivia, and Throb are all supported. It can help calibrate a sound card to a time signal and do frequency measurement tests. As with all of the FL suite, Flrig supports PowerPC, Intel (i386) and Apple Silicon (M1) processors with individual downloads available for each architecture. Download the latest version of Fldigi here.
