Release: WSJT-X Version 1.9.0-rc4

Changes from WSJT-X Version 1.9.0-rc3 include the following:

– Corrected a number of flaws in Fox and Hound behavior, FT8
DXpedition Mode

– Decoded CQ calls where a prefix has been used as a suffix should
have the DXCC entity name assigned correctly in almost all cases

– Improved AFC capability for the wider JT65 sub-modes to help with
drifting signals

– Better support for macOS using hi-DPI Retina displays

– New UDP message that allows external applications to highlight
decoded callsigns

– Main-screen geometry and state of the “splitter” setting between its
two text windows is now properly restored after program restart.

– New simulator jt49sim[.exe] replaces jt4sim and jt9sim

– Correct S/N measurements for the JT9 slow/wide submodes

– Other minor bug fixes

– Updated copy of cty.dat

A third beta release, v1.9.0-rc3, has been tested in the field over the
past several weeks. These tests included a public test of FT8
DXpedition Mode conducted on April 7. A few additional bugs were
identified and corrected, and the -rc4 release also includes some minor
enhancements.

A General Availability (GA) release of WSJT-X Version 1.9.0 will be
announced at a suitable time, probably in the near future. After that
you should stop using any -rc# release candidate.

Short list of changes since WSJT-X Version 1.9.0-rc3:

1. Corrected several flaws in Fox and Hound behavior, FT8 DXpedition Mode

2. Decoded CQ messages where a prefix has been used as a suffix now have
the DXCC entity name assigned correctly in almost all cases

*Third Public Test of FT8 DXpedition Mode*
————————–—————-

If you decide to install v1.9.0-rc4, please help us by participating in
the third public test of FT8 DXpedition Mode scheduled for Saturday, May
5. Once again, the goal is to simulate a rare-DXpedition pileup by
having many stations (“Hounds”) calling and trying to work a designated
pseudo-DXpedition station (“Fox”).

Everyone participating in the test must use WSJT-X v1.9.0-rc4. In
addition, you must read, understand, and carefully follow the
instructions posted here:
http://physics.princeton.edu/pulsar/k1jt/FT8_DXpedition_Mode.pdf
Please be sure to read this document carefully, again. Some details of
the operating procedures are different from previous versions.

If you have legitimate access to more than one callsign (spouse, a club
call, or whatever) please feel free to call and work each Fox more than
once. The more Hounds, the better: we want the test pileup to be as
deep as possible.

The third public test will take place as follows, with each session
lasting one hour:

Date UTC Frequency Fox Callsign Operator
————————–————————-
May 5 1400 14.090 MHz W1/KH7Z N1DG
May 5 1500 14.090 W7/KH7Z AA7A
May 5 1600 14.090 K1JT K1JT

If last-minute instructions are necessary they will be announced on the
“Ping Jockey Relief” chat page:
http://www.pingjockey.net/cgi-bin/pingtalkB

As we have done before, we will plan to publish lists of all Hound
callsigns copied and those worked by each Fox.
