A second beta version of WSJT-X version 1.9.0 has been released, the WSJT development group announced this week. The “release candidate,” as it’s called, is designated as version 1.9.0-rc2. An initial beta release has already been field-tested by a small group of users. The WSJT development group said a primary purpose of the second beta release is to allow further field testing of the new FT8 “DXpedition Mode,” designed to enable DXpeditions to make FT8 contacts at very high rates, and it is inviting the Amateur Radio community to participate in a public test run of FT8 DXpedition Mode on the evening of March 6 (North American time).
“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’),” the announcement said. All test participants must use WSJT-X version 1.9.0-rc2.
