WSJT-X V2.0 now released

WSJT-X V2.0 has been officially released and should be adopted as soon as possible. There are new protocols for FT8 and MSK144. Joe Taylor K1JT is urging all amateurs to adopt the new standard as this is not compatible with older versions. For a period, this will cause some confusion, but I think I'll download the new version later. Call CQ above 2kHz audio with the new version!!

See David's note below: the "above 2kHz applied for the "rc" candidates only, so people can use below 2kHz audio with WSJT-X V2.0 fully released version, although FT8 using the old protocol will not decode

New version of FT8

Older "release candidate" versions of WSJT-X 2.0 ceased to work as from today. The latest version is "rc5" which is expected to be very close to the released version due soon.

With "rc5" a new protocol has been introduced. If people are using older "rc" versions FT8 signals will be treated as noise and will not decode. On 160m I have seen several signals already that have not decoded.

So, it is important that FT8 users upgrade right away to WSJT-X 2.0 rc5. Do it now!!
