WSJT-X 2.0 RC1 Candidate Release is out… a major upgrade!

To all enthousiast digital users, a new WSJT-X release 2.0 RC1 candidate is out now for all major platform.


A majority of new program features involve the FT8 and MSK144
protocols.  Both modes have been upgraded to use use 77-bit
information payloads rather than the 75 bits of the older FT8 protocol
or 72 bits of JT4, JT9, JT65, MSK144, and QRA64.  Cyclic redundancy
checks (CRCs) that protect against false decodes have been increased
from 12 to 14 bits (FT8) and from 8 to 13 bits (MSK144).

Have fun and stay tuned!
