Since the topic hasn't appeared on this list yet, I figured it would be a
good idea to make folks here aware of the pending WSJT FT4 mode in case
they hadn't seen it already.
The tl;dr:
* 2.5X faster than FT8
* Same contesting features as FT8
* Automatic search and pounce mode
* 144.170MHz proposed 2m frequency

(video
of a club talk Joe Taylor made about FT4)
Notable dates:
• April 29: Second announcement, with links to downloadable installation
packages
for WSJT-X 2.1.0-rc5
• May 9, 0000 – 0100 UTC: FT4 practice session, 7.090 MHz
• May 14, 0000 – 0100 UTC: FT4 practice session, 7.090 MHz
• June 5, 0000 – 0100 UTC: FT4 practice session, 7.090 MHz (if needed)
• July 15: General Availability (GA) release of WSJT-X 2.1.0
An RC version is already available now for testing. In other words, you get
to juggle another new digital mode for this summer's contest season!
As I mentioned earlier, the proposed 2m frequency is 144.170MHz (USB dial
frequency). It's inevitable that this becomes as popular; if not more
popular than FT8 for contests. You would still need FT8 to dig out really
weak signals, but for everyone that bangs into your station at -10db and
higher, FT4 is a no brainer given the potentially higher QSO/hr count.
If you have direct feedback for the developers, especially about the
frequency selection, I suggest you send that to the wsjt-devel mailing list
rather than here.
