fw:[wsjt-devel] WSJT-X v1.9.0-rc2: Testing of FT8 DXpedition Mode<\/p>\n
The WSJT Development Group is pleased to announce a Release Candidate of
\nWSJT-X Version 1.9.0. This is a second beta release, so it’s called
\nv1.9.0-rc2. A first candidate release, v1.9.0-rc1, has already been
\ntested in the field by a small test group. A General Availability (GA)
\nrelease of v1.9.0 will be announced at a suitable time in the near
\nfuture. After that time you should no longer use any -rc# candidate.<\/p>\n
Here\u2019s a short list of features and capabilities added to WSJT-X since
\nVersion 1.8.0:<\/p>\n
1. New FT8 DXpedition Mode to facilitate high QSO rates in pileup situations<\/p>\n
2. Decoding improvements for JT65 mode, including a priori (AP) decoding
\nwhen VHF\/UHF\/Microwave features are enabled<\/p>\n
3. Optional Auto-Sequencing in JT4, JT9, and JT65 when VHF\/UHF\/Microwave
\nfeatures are enabled<\/p>\n
4. Better suppression of low-confidence false decodes generated by AP
\ndecoding in FT8 mode<\/p>\n
5. Improved decoding performance for WSPR mode, especially effective at
\nLF and MF<\/p>\n
6. Minor adjustments to auto-sequencing behavior<\/p>\n
7. More flexible Doppler control features for EME<\/p>\n
8. Improved waterfall sensitivity for very weak signals<\/p>\n
9. Automatic real-time forwarding of logged information to N1MM Logger+<\/p>\n
10. Expanded and improved UDP messages sent to companion programs<\/p>\n
11. Bug fixes and other minor tweaks to user interface<\/p>\n
\n*Public Test of FT8 DXpedition Mode*
\n————————————<\/p>\n
A primary purpose of this beta release is to allow field testing of FT8
\nDXpedition Mode. If you decide to install v1.9.0-rc2, please help us by
\nparticipating in a public test run scheduled for March 6-7 (evening of
\nMarch 6, NA time). The goal is to simulate a rare-DXpedition pileup by
\nhaving many stations (“Hounds”) calling and trying to work a designated
\npseudo-DXpedition station (“Fox”). Note that everyone participating in
\nthe test *MUST* use WSJT-X v1.9.0-rc2. In addition, you must read and
\ncarefully follow the instructions posted here:
\nhttp:\/\/physics.princeton.edu\/pulsar\/k1jt\/FT8_DXpedition_Mode.pdf<\/p>\n
Reading the instructions for *FT8 DXpedition Mode* is very important!<\/p>\n
If you have legitimate access to more than one callsign (XYL, club call,
\nor whatever) please feel free to call and work the Fox more than once.
\nWe want the test pileup to be as deep as possible.<\/p>\n
The scheduled test will take place as follows:<\/p>\n
Date UTC Frequency
\n————————-
\nMar 6 2300 14.080 MHz
\nMar 7 0000 10.141
\nMar 7 0100 7.080
\nMar 7 0200 3.585<\/p>\n
The indicated USB dial frequencies are subject to change, depending on
\nother band usage at the time. If last-minute instructions are necessary
\nthey will be posted here:
\nhttp:\/\/physics.princeton.edu\/pulsar\/k1jt\/DXpedition_Mode_Test.txt<\/p>\n
Note that the dial frequencies are NOT the conventional FT8 operating
\nfrequencies for each band. DXpedition Mode should *NOT* be used on
\nstandard FT8 operating frequencies.<\/p>\n
Of course you may also choose to do your own testing of FT8 DXpedition
\nMode together with a group of colleagues. One station would act as Fox,
\nthe others as Hounds. In such tests the Fox will be limited to using a
\nsingle Tx “slot”.<\/p>\n
\nInstallation packages for Windows, Linux, Macintosh, and Raspian Jessie
\nhave been posted on the WSJT web site here:

\npackage for your system.<\/p>\n
