FT8 - The Big Changeover

On the 10th of December 2018, the new upgraded version of FT8 was officially released. The new WSJT-X Ver 2.0 version replaces the earlier 1.8 and 1.9 versions which were hugely popular.

The BIG problem however is that the new FT8 protocols have been enhanced in a way that is not backward compatible with older versions of the program. i.e. those using the new version can't talk to those using the old version.

There is a three week window for users to upgrade by the start of the new year.

“The new protocols become the worldwide standards starting on December 10, 2018, and all users should upgrade to WSJT-X 2.0 by January 1, 2019.” ... Joe Taylor K1JT, WSJT-X home page.

Considering the huge number of people using FT8, it might seem at first like trying to herd some cats. Will everyone change over? Will there be people using both systems in 2019?

On the 10th of December, I adopted a 'wait and see' policy to see how many people changed. On the 12th and 13th of December, I noticed that I was hearing FT8 signals on 28 MHz and not decoding them. I checked the usual time and frequency settings and all was ok.

Perhaps the old 1.9 version might be ok on the lower HF bands like 20m where there are plenty of signals but there are very few signals on 28 MHz. If I can't decode a signal then it's a big deal.

On the 14th of December, I changed over to Version 2.0 and one of the first signals I heard on 28 MHz was VP8LP on the Falkland Islands in the South Atlantic.

I have no doubt that there will be plenty of people using the old version for a while but upgrading to version 2.0 as soon as possible seems like the best option.
