Quick Start for DXpedition Mode
|
|
-------------------------------
|
|
|
|
These notes are intended for operators already familiar with WSJT-X
|
|
and FT8 mode. QSOs between the Dxpedition ("Fox") and other stations
|
|
("Hounds") are completed with as little as one transmission per Hound,
|
|
as in the following examples:
|
|
|
|
----------------------------------------------------------------------------
|
|
Fox (300-600 Hz) Hounds
|
|
----------------------------------------------------------------------------
|
|
1. CQ KH1DX AJ10
|
|
2. KH1DX K1ABC FN42, KH1DX W9XYZ EN37, ...
|
|
3. K1ABC KH1DX -13
|
|
4. KH1DX K1ABC R-11
|
|
5. K1ABC RR73; W9XYZ <KH1DX> -17
|
|
6. KH1DX W9XYZ R-16
|
|
7. W9XYZ RR73; G4AAA <KH1DX> -09
|
|
8. ...
|
|
----------------------------------------------------------------------------
|
|
|
|
Everybody sets dial frequency to an agreed number and uses CAT control
|
|
with Split Operation (either *Rig* or *Fake It*). Fox transmits up to
|
|
5 signals simultaneously, at audio frequencies 300, 360, ... 540
|
|
Hz. Hounds make initial calls (e.g., line 2 above) anywhere in the
|
|
range 1000 - 4000 Hz. They send "R+rpt" 350 Hz above the frequency
|
|
where Fox called them.
|
|
|
|
|
|
INSTRUCTIONS FOR FOX
|
|
--------------------
|
|
|
|
1. Start WSJT-X in FT8 mode. Select *Fox* on the *Settings ->
|
|
Advanced tab*. On the main window, check *Tx even/1st*, *Auto Seq*,
|
|
and *Hold Tx Freq*; uncheck *Call 1st*. Set *Tx 300 Hz* and select
|
|
Tab 3.
|
|
|
|
2. In Fox mode the left window (called "Band Activity" in normal FT8
|
|
mode) is labeled "Stations calling DXpedition <MyCall>". It will be
|
|
filled with a sorted list of calling Hounds. You can sort by Call,
|
|
Grid, S/N, Distance, or Random order by using the comboBox at top
|
|
right of Tab 3. You can limit the displayed Hound callsigns to those
|
|
no stronger than *Max dB*. Fox might use this feature to discourage
|
|
Hounds from engaging in a QRO arms race.
|
|
|
|
3. *N Slots* sets the number of simultaneous Fox signals to be used.
|
|
Fox carries out as many as *N Slots* QSOs simultaneously.
|
|
|
|
4. *Repeats* sets the maximum number of repeat transmissions of the
|
|
same message. A QSO is aborted when this number would be exceeded.
|
|
|
|
5. The *CQ* comboBox on Tab 3 offers a selection of directed CQ
|
|
messages. *Reset* clears the QSO queue.
|
|
|
|
6. The Fox operator's main task is to select Hounds to be called and
|
|
worked. The text box on Tab 3 holds the "QSO queue": a list of Hound
|
|
calls to be worked. Hit Enter to select the top callsign from the
|
|
sorted list of callers (left window), or double-click on any
|
|
particular call. Either actiion moves that Hound into the "QSO
|
|
queue".
|
|
|
|
7. The right window displays decodes of signals below 1000 Hz.
|
|
Normally these should include only Hound messages containing "R+rpt"
|
|
and Fox's own transmissions.
|
|
|
|
8. To get things started, toggle *Enable Tx* to red. If a Hound call
|
|
is available in the QSO queue, that station will be called. If the
|
|
QSO queue is empty, Fox calls CQ.
|
|
|
|
9. If you're using Nslots = 2 or higher, your signal no longer has
|
|
a constant envelope. To avoid producing intermod sidebands you need
|
|
to ensure linearity in your Tx system. One way to get things about right
|
|
is to use the WSJT-X *Tune* button to generate a pure tone. Reduce the
|
|
Tx audio level until your power output decreases by 10% or so. Use this
|
|
level for your Fox transmissions.
|
|
|
|
NOTE: If you are generating Nslots signals, the average power in each one
|
|
will be 1/Nslots^2 of its normal value for single-signal transmissions.
|
|
|
|

The following features are not yet implemented for Fox:
|
|
|
|
1. Enforce all required settings
|
|
2. Tx message timeout
|
|
3. Manual abort of selected QSO
|
|
4. All Tx and Rx messages to all.txt
|
|
5. Additional sort criteria for Hound calls
|
|
6. Selectable timeout for keeping Hounds in the sorted list
|
|
7. Display number of active callers
|
|
8. Display QSO rate
|

|
INSTRUCTIONS FOR HOUND
|
|
----------------------
|
|
|
|
1. Start WSJT-X in FT8 mode. Select *Hound* On the *Settings ->
|
|
Advanced* tab. On the main window check *Auto Seq* and uncheck *Tx
|
|
even/1st*, *Call 1st*, and *Hold Tx Freq*. Set *Tx nnnn Hz* to some
|
|
frequency between 1000 and 4000 Hz, and select *Tab 1*. Enter Fox's
|
|
callsign and locator in DX Call and DX Grid, select Tx1, and start
|
|
*Monitor*.
|
|
|
|
2. When you have copied Fox, hit *Enable Tx* to call him. You may
|
|
keep calling until he answers. You may wish to move your TxFreq
|
|
around, hoping to find a clear calling frequency.
|
|
|
|
3. When you are called by Fox with a signal report, your next
|
|
transmission will automatically be sent as Tx3 ("R+rpt"). When Fox
|
|
receives that message he responds with "RR73", and your QSO is
|
|
complete!
|
|
|
|
|
|
The following features are not yet implemented for Hound:
|
|
|
|
1. Force all required settings
|
|
2. React properly to directed CQs from Fox
|
|
3. Disable Tx2, 4, 5, 6
|
|
4. For Tx1, enforce TxFreq >= 1000 Hz
