Subject: [wsjt-devel] Second Public Test of FT8 DXpedition Mode: early results
----

Hi all,

Many people have asked for a list of stations heard and worked in the
Second Public Test of FT8 DXpedition Mode, held on April 7. I have attached a brief summary. It's a plain text file containing four lists of callsigns:

1. 61 logged by W1/KH7Z in 36 minutes: rate = 61*60/36 = 102/hour

2. 55 logged by K1JT in 21 minutes: rate = 55*60/21 = 157/hour

3. 174 logged by W7/KH7Z in 60 minutes: rate = 174/hour

4. 390 unique calls copied by one or more of the three Foxes

It's worth noting that Ned/AA7A, operator at W7/KH7Z, learned to manage his queues much more effectively as his hour progressed. After a program restart at 1532 UTC he worked 105 additional stations, a rate of 105*60/28 = 225/hour during the remaining part of the hour.

Slowly but surely, we are optimizing the software and improving our "FoxOp" skills. Further progress will definitely be possible!

For this test the three Foxes were configured as follows:

Call Grid PEP PerSlot Antenna
----------------------------------------------------
W1/KH7Z FN42 500 W 20 W SteppIR at 15, az=50
K1JT FN20 100 W 4 W Dipole at 17m
W7/KH7Z DM43 500 W 20 W 3 el at 22m, az=45

Subject: [wsjt-devel] Premature use of FT8 DXpedition Mode
----

Everyone paying attention should already know what's contained in this
message -- but it's clear that some do not.

The current General Availability (GA) release of WSJT-X is v1.8.0. That
program version does not include FT8 DXpedition Mode.

We have made beta-level "release candidates" available for the explicit
purpose of testing FT8 DXpedition Mode. The release candidates have
included cautionary warnings to the effect that in its present form,
DXpedition Mode should be used only for controlled testing.

A few operators or groups have ignored our warnings and tried to use FT8
DXpedition Mode in true pileup situations. The consequences are
predictably bad -- especially when the offending operator(s) have chosen
their frequencies badly and other operators are using a mix of program
versions including v1.8.0, v1.9.0-rc2, v1.9.0-rc3, some version of JTDX.

FT8 DXpedition Mode is not yet ready for “production” use. Until WSJT-X
v1.9.0 is fully released -- not a beta-level "release candidate", but a
full General Availability release -- DXpedition Mode should be used only
in controlled test situations.

The next public test of FT8 DXpedition Mode conducted by the WSJT
Development Group will be conducted on April 7, a little over a week
from now. You are cordially invited to join us for this test. See the
announcement posted here yesterday (Subject: WSJT-X v1.9.0-rc3: Testing
of FT8 DXpedition Mode) for details.

----

The second public test of FT8 DXpedition mode will be conducted on April
7, a little over a week from now. You are cordially invited to join us
for this test. See the original announcement (copied below) for details.

Even if you read it before, be sure to read the latest revision of the
*FT8 DXpedition Mode User Guide.* It is dated March 28 and is available
here:
http://physics.princeton.edu/pulsar/k1jt/FT8_DXpedition_Mode.pdf
There are some changes from previously posted instructions!

I draw your particular attention to the following sentences found on page 1:
############################################################################
Please note: DXpedition Mode is not yet ready for “production” use.
Until WSJT-X v1.9.0 is fully released, this mode should be used only in
controlled test situations. Please remember to send us your test results.

....

Subject to future revision, we are temporarily suggesting the following
frequencies for testing DXpedition mode: 1.8265, 3.567, 7.066, 10.1405,
14.105, 18.095, 21.067, 24.911, 28.067 MHz.
############################################################################

The first warning is included because several operators or groups have
been trying, against our advice, to use the not-yet-complete DXpedition
Mode in real pileup situations. This misuse of a WSJT-X beta release
(or of code taken from the WSJT-X development branch) has been
counter-productive, to say the least.

The second item copied above is the result of early efforts to identify
suggested FT8 DXpedition Mode operating frequencies for each HF band
that will minimize interference with other modes. We will welcome
thoughtful suggestions that might improve this list of suggested
frequencies.

We hope to see you in the pileups calling W1/KH7Z and W7/KH7Z on 14.105
MHz, 1400-1600 UTC on April 7!

Subject: [wsjt-devel] WSJT-X v1.9.0-rc3: Testing of FT8 DXpedition Mode
----

The WSJT Development Group is pleased to announce a third Release
Candidate of WSJT-X Version 1.9.0. A second release candidate,
v1.9.0-rc2, has been tested in the field over the past three weeks,
including a public test of FT8 DXpedition Mode conducted on March 6-7.

A General Availability (GA) release of v1.9.0 will be announced at a
suitable time, probably in the near future. After that time you should
stop using any -rc# release candidate.

Here’s a short list of features and capabilities added to WSJT-X since
Version 1.9.0-rc2:

1. Corrected a number of flaws in Fox behavior, FT8 DXpedition Mode

2. Allow Hounds to use compound callsigns in FT8 DXpedition Mode

3. Write debugging information to FoxQSO.txt

4. Fix the "Blue Decode Button" bug

5. Allow partial processing of incoming UDP Reply messages so that
non-CQ/QRZ decodes can be processed. The processing is the same as
double-clicking the same decoded message within WSJT-X except that
"Enable Tx" will not be enabled.

6. Send DX grid locator to wsjt_status.txt, for use by applications like
PstRotatorAZ

7. Correct the display of DXCC status of KG4 calls

8. Updated copy of cty.dat

9. Updates to documentation

10. Updated Hamlib functionality including changes to the Yaesu FT-817
back end that allows the uBITx kit transceiver to be CAT controlled
by WSJT-X.

10. Other minor bug fixes

*Second Public Test of FT8 DXpedition Mode*
-------------------------------------------

If you decide to install v1.9.0-rc3, please help us by participating in
the second public test of FT8 DXpedition Mode scheduled for April 7.
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"). Note that everyone participating in
the test *MUST* use WSJT-X v1.9.0-rc3. 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. A few of its
details are different from the previous version.

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

The scheduled test will take place as follows:

Date UTC Frequency Fox callsign Operator
---------------------------------------------------
April 7 1400 14.105 MHz W1/KH7Z N1DG
April 7 1500 14.105 W7/KH7Z AA7A

Subject: [wsjt-devel] DXpedition Mode Test Results
----

Hi all,

Here are a few highlights of results from last night's public test of FT8 DXpedition Mode:

- The overwhelming majority of participating Hounds operated as intended, and according to instructions. I copied 190 unique Hound callsigns during the 2300 hour (when I was acting as Fox on 20m) and 330 unique callsigns during the whole four hours. I suppose that we had at least 400-500 participants, maybe more.

- Fox's multi-signal capability worked very well at the tested values, NSlots = 3, 4, and 5. This feature is surely a "keeper", and I see no reason not to use NSlots = 5 -- especially if Fox is running power.

- In the four test hours the number of "QSOs" logged by Foxes on 20, 30, 40, and 80m was 320, 189, 454, and 351. However, a regrettable program bug was preventing deletion of Hound callsigns from Fox's "QSO-in-Progress" list after a QSO had been logged. As a result, many repeated "RR73" messages were sent, many dupe QSOs were logged, and the QSO-in-Progress list kept growing. As another consequence, some QSOs took up to ~20 min to complete, and a number of Hounds who had been sent a report never received their QSO-confirming "RR73".

- AA7A actually worked 120 unique calls in the 40m hour, and the other Foxes worked comparable slightly lower numbers. When this program bug is corrected, hourly QSO in the 300-400 range should certainly be achievable.

- Of course, some Hounds did not operate as intended. Several kept trying to raise Fox by calling below 1000 Hz. (Most of these that I noticed were from non-English speaking countries. We will probably need translations of the FT8 DXpedition Mode User Guide.) A few would-be Hounds were not obviously not using v1.9.0-rc2, and were calling Fox "blind" in 1st sequence. A few Hounds tried using compound callsigns, which is not supported -- and which needs to be made more clear in the instructions.

- Nearly everybody noticed the XE1GK calling CQ on the low-end Fox frequency and working people these. Please don't be too hard on Ignacio: he obviously misunderstood what was supposed to be happening, and how to operate in the test run. He sent me an abject apology. Anyway, his signal helped us to evaluate how well we can cope with QRM and DQRM.

Two operating hints that should be used as needed, but in general were not:

- Hounds should manually reset their Tx frequency as needed to evade QRM.

- Fox may decide to use the randomizing feature to vary his own Tx frequency.


I list here some relatively minor bugs and other things that came to light during the test run:

- Spurious "Callsign mismatch" warning messages were displayed to the Fox operator.

- Fox's log window should automatically scroll to the bottom. Or maybe it should simply show the most recent ~10 QSOs logged.

- I'm not sure that Fox's "Max Calls" parameter worked as designed.

- Sometimes Fox sent RR73 to the same station in more that one slot, in the same transmission.

- The dreaded "Blue Decode" button was seen by some.

- Hounds sometimes send a spuriously low signal report to Fox, even when Fox is loud.

- If Hound hits "Enter" with the DX Call box empty, a blank message can be transmitted.

- It a random station (not Fox) calls a Hound, it can trigger a Hound transmission just as if Fox had called.

- Previously decoded Hound calls can sometimes reappear in Fox's left window, when they should not.


Finally, let me outline a few new features we may decide to implement.

- At least for debugging, and possibly as an option, offer a display window that shows the Fox operator the contents of all active queues.

- Limit the number of QSOs in progress to no more than NSlots.

- Option to suppress display of the waterfall timestamp.

- Have Fox call CQ in one slot at least once every few (1 or 2?) minutes.

- Should Hound's Tx3 frequency be re-randomized for each repeat try?

I'm sure there is more to be said, but that will do for now. Depending on programming progress and on my own travel schedule, we may schedule another public test within a few weeks.

Hi all,

I write to remind you of the public test of *FT8 DXpedition Mode*
scheduled for March 6-7. The more participants, the better!
The main goal is to simulate pileups in which many "Hounds" call and
attempt to work a desirable rare DX station, the "Fox", and to maximize
the resulting QSO rate. We hope you can be there and work each of our
Foxes on each band.

All participating stations must use program version WSJT-X v1.9.0-rc2.
If you don't yet have it, download links are available here:
https://physics.princeton.edu/pulsar/k1jt/wsjtx.html

Detailed instructions for Fox and Hound stations are posted here:
http://physics.princeton.edu/pulsar/k1jt/FT8_DXpedition_Mode.pdf
It's important to read and follow these instructions carefully! Don't
just try to wing it.

Each hour during the test has a designated frequency and Fox callsign,
"Fox_A" in the following table.

Date UTC Freq Fox_A Fox_B NSlots
-------------------------------------------
Mar 6 2300 14.080 K1JT W7/KH7Z 3
Mar 7 0000 10.141 W1/KH7Z K9AN 5
Mar 7 0100 7.080 W7/KH7Z K1JT 4
Mar 7 0200 3.585 K9AN W1/KH7Z 3

As you will know after reading the FT8 DXpedition Mode User Guide, Fox
can conduct up to "NSlots" QSOs simultaneously. W1/KH7Z will be
operated by AA7A, and W1/KH7Z by N1DQ.

Fox_A will operate for the full hour if plenty of Hounds keep calling.
Fox_B is on standby reserve. If the QSO rate for Fox_A approaches zero
at the half-hour mark, Fox_A will stop transmitting and Fox_B will call CQ.

If you (as a Hound) can legitimately use more than one callsign -- your
spouse's call, club call, etc. -- please try to work each Fox multiple
times. No dupe QSOs with the same call and same band, though.

Real-time liaison will be available via the "Ping Jockey Relief" chat
page (PJB), https://www.pingjockey.net/cgi-bin/pingtalkB . Everyone
should monitor this page for possible announcements of frequency changes
or switch-overs from Fox_A to Fox_B. 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 to 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, wsjtgroup@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, working each Fox on
each band!

fw:[wsjt-devel] WSJT-X v1.9.0-rc2: Testing of FT8 DXpedition Mode

The WSJT Development Group is pleased to announce a Release Candidate of
WSJT-X Version 1.9.0. This is a second beta release, so it's called
v1.9.0-rc2. A first candidate release, v1.9.0-rc1, has already been
tested in the field by a small test group. A General Availability (GA)
release of v1.9.0 will be announced at a suitable time in the near
future. After that time you should no longer use any -rc# candidate.

Here’s a short list of features and capabilities added to WSJT-X since
Version 1.8.0:

1. New FT8 DXpedition Mode to facilitate high QSO rates in pileup situations

2. Decoding improvements for JT65 mode, including a priori (AP) decoding
when VHF/UHF/Microwave features are enabled

3. Optional Auto-Sequencing in JT4, JT9, and JT65 when VHF/UHF/Microwave
features are enabled

4. Better suppression of low-confidence false decodes generated by AP
decoding in FT8 mode

5. Improved decoding performance for WSPR mode, especially effective at
LF and MF

6. Minor adjustments to auto-sequencing behavior

7. More flexible Doppler control features for EME

8. Improved waterfall sensitivity for very weak signals

9. Automatic real-time forwarding of logged information to N1MM Logger+

10. Expanded and improved UDP messages sent to companion programs

11. Bug fixes and other minor tweaks to user interface


*Public Test of FT8 DXpedition Mode*
------------------------------------

A primary purpose of this beta release is to allow field testing of FT8
DXpedition Mode. If you decide to install v1.9.0-rc2, please help us by
participating in a public test run scheduled for March 6-7 (evening of
March 6, NA 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"). Note that everyone participating in
the test *MUST* use WSJT-X v1.9.0-rc2. In addition, you must read and
carefully follow the instructions posted here:
http://physics.princeton.edu/pulsar/k1jt/FT8_DXpedition_Mode.pdf

Reading the instructions for *FT8 DXpedition Mode* is very important!

If you have legitimate access to more than one callsign (XYL, club call,
or whatever) please feel free to call and work the Fox more than once.
We want the test pileup to be as deep as possible.

The scheduled test will take place as follows:

Date UTC Frequency
-------------------------
Mar 6 2300 14.080 MHz
Mar 7 0000 10.141
Mar 7 0100 7.080
Mar 7 0200 3.585

The indicated USB dial frequencies are subject to change, depending on
other band usage at the time. If last-minute instructions are necessary
they will be posted here:
http://physics.princeton.edu/pulsar/k1jt/DXpedition_Mode_Test.txt

Note that the dial frequencies are NOT the conventional FT8 operating
frequencies for each band. DXpedition Mode should *NOT* be used on
standard FT8 operating frequencies.

Of course you may also choose to do your own testing of FT8 DXpedition
Mode together with a group of colleagues. One station would act as Fox,
the others as Hounds. In such tests the Fox will be limited to using a
single Tx "slot".


Installation packages for Windows, Linux, Macintosh, and Raspian Jessie
have been posted on the WSJT web site here:

From Joe Taylor:

“Hi all,

You have probably heard something about recent efforts to develop a special "FT8 DXpedition Mode" in WSJT-X. This message aims to bring you up-to-date on our progress, and generally to make our plans more widely known.

The basic goal of *FT8 DXpedition Mode* is to enable DXpeditions to make FT8 QSOs at the highest possible rates. We have been working together with members of the Baker Island (KH1/KH7Z) group. Their planned expedition will take place in June-July 2018. Like most major DXpeditions, this one will almost certainly make a majority of its QSOs using SSB and CW. However, the group is well aware of the rapid rise of FT8 popularity, and they plan to use FT8 as well.

Making FT8 QSOs with KH1/KH7Z will require the DXpedition and everyone trying to work them to use a new, yet-to-be-released version of WSJT-X.

We have tested the new program features on the air several times, and found them to work well. Another test run will probably be scheduled in a month or so. There will be plenty of advance publicity inviting others to upgrade to a "Release Candidate" called WSJT-X v1.9.0-rc1, and to join in trying to work one or more specific "pseudo-DXpedition" stations at a certain time and frequency. In this way, we hope to continue shaking bugs out of the program and generally to improve its usability -- both for the DX operator and those seeking to work him.

FT8 DXpedition mode includes a number of new and innovative features.
For further details on what's in store, I draw your attention to a draft of the "FT8 DXpedition Mode User Guide" posted here:
http://physics.princeton.edu/pulsar/k1jt/FT8_DXpedition_Mode.pdf

With best wishes,

-- 73, Joe, K1JT, for the WSJT Development Group”
