Hi all,
I write to remind you of the second public test of *FT8 DXpedition Mode*
scheduled for Saturday, April 7, 1400-1600 UTC. You are cordially
invited to participate -- the more participants, the better!
Our main goal is to simulate pileups in which many "Hounds" call and
attempt to work a desirable rare DX station, the "Fox". The test will
help us to improve our software so as to maximize the practical QSO rate
in such situations. We hope you can be there and try to work both Foxes.
Here's the detailed schedule:
Date UTC Frequency Fox Callsign Operator
---------------------------------------------------
April 7 1400 14.105 MHz W1/KH7Z N1DG
April 7 1500 14.105 W7/KH7Z AA7A
All participating stations must use program version WSJT-X v1.9.0-rc3.
If you don't yet have it, download links are available near the bottom
of the page here:
https://physics.princeton.edu/pulsar/k1jt/wsjtx.html
[If you are compiling the program for yourself, be sure to use code
revision r8576 or later, taken from the repository's WSJT-X development
branch. All revisions since r8576 will perform identically in FT8
DXpedition Mode.]
Detailed instructions for both Fox and Hound are posted here:
http://physics.princeton.edu/pulsar/k1jt/FT8_DXpedition_Mode.pdf
Some details in these instructions have changed, so be sure to read and
follow the latest instructions carefully! Don't just try to wing it.
As you will know after reading the instructions, Fox can conduct up to 5
QSOs simultaneously, using frequency slots spaced by 60 Hz. Fox
transmissions always occur in the frequency range 300-900 Hz above dial
frequency.
If you (as a Hound) can legitimately use more than one callsign -- your
spouse's call, club call, etc. -- feel free to work each Fox multiple
times. No dupe QSOs with the same call, though.
Real-time liaison will be available on the "Ping Jockey Relief" chat
page (PJB), https://www.pingjockey.net/cgi-bin/pingtalkB . Everyone
should monitor this page for possible last-minute announcements of a
frequency change, etc. To ensure that announcements from Fox stations
are easily visible, Hounds should monitor PJB but not post messages
there during the test.
The deepest pileups will help us tune the final-release software version
for optimum performance on both Fox and Hound sides. After the test,
please post any comments you feel will be helpful to one of our two
email forums, wsjtgr...@yahoogroups.com or
wsjt-devel@lists.sourceforge.net . You will need to be subscribed to
the list in order to post there.
We sincerely hope you can join us for this test, and that you will work
both Foxes!
-- 73, Joe, K1JT (for the WSJT Development Group)
