FT8/FT4 presentation

Southgate News has a link to a USA YouTube presentation on these modes. There are lots of presentations about these digital modes on YouTube. FT8 works with low power and simple antennas, but is not a mode for chatting. 

I have to admit, I have not yet tried FT4.

FT4 - not tried

Although I love FT8, I have a confession to make: I have never tried FT4!

At some point, I must do so. It is much faster than FT8, but probably not as good on very weak signals. I don't know about Doppler, but I suspect it might be better on very brief Es openings.

FT4

Although release candidate versions of WSJT-X have been released including FT4, I think I shall now wait for the fully released version before installing. FT4 sounds like a useful Es mode with its shorter periods. It is not quite as sensitive, but with Es signals are often strong even with QRP.

FT4

Digital mode FT8 has become enormously popular. Apparently a new release candidate of the faster FT4 is due out in a few weeks. I have yet to try FT4.

FT4 digital contest mode

My friend Steve G1KQH alerted me to this. It is a new variation (faster) of FT8 for digital contests.
