[TVARC] FOX/HOUND or HOUND/FOX

[Anthony Hackenberg]

Hi Earle (“Hound Dog”),

Joe Taylor’s user guide on FT8 DXpedition mode says you (a “Hound”) wait
until you successfully decode a KH1/KH7Z’s (the “Fox’s”) CQ.  Here’s Joe’s
typical sequence in this user guide:

When Fox is running a pileup the standard messages look something like the
following, where Fox is signing KH1/KH7Z:

            FOX.                            HOUND

1. CQ KH1/KH7Z

2. KH7Z K1ABC FN42, KH7Z W9XYZ EN37, ...

3. K1ABC KH7Z -13

4. KH7Z K1ABC R-11

5. K1ABC RR73; W9XYZ <KH1/KH7Z> -17

6. KH7Z W9XYZ R-16

7. W9XYZ RR73; G4AAA <KH1/KH7Z> -09

8. ...


Note that Hounds use Fox’s base call, not his full compound callsign.


Later, in that user guide, Joe says:


9. Please do not call Fox if you are not receiving his transmissions.

Do not call Fox if he issues a directed CQ (“CQ EU”, “CQ 7”, …) and your
continent or numerical call area does not match the requested one.

Calling out of turn only creates QRM, and will certainly not get you a QSO.


10.Remember that FT8 is a weak-signal mode.

Contacts can be made reliably with signals well below the audible
threshold.

The Fox operator may explicitly decide to answer only calls with signal
strength below some limit, for example S/N = –10 dB.

In many cases you will not need and should not use an amplifier.

It’s more important to find a calling frequency free of QRM.


11.After you have copied Fox calling CQ or working someone else,
double-click on his decoded message to call him.

You may keep calling until he answers, perhaps changing your Tx frequency
in the hope of finding a frequency clear of interference.

Use Shift+Click on the waterfall to change your Tx frequency — the red
“goal posts” marker on the waterfall scale.

You will need to re-activate Enable Tx (or hit Enter on the keyboard) at
least once every two minutes.

  (This restriction is to ensure that an operator is present and paying
attention.)


12.After you receive a signal report from Fox, WSJT-X will automatically
send your next transmission as message Tx 3 (“R+rpt”) at the same frequency
at which Fox called you.

If you need to send “R+rpt” more than once, subsequent transmissions will
be moved 300 Hz higher or lower.

Note that WSJT-X will send this message even if Enable Tx is disabled, and
even if you have not called Fox for several Tx sequences.

If you have stopped calling Fox because you will be leaving the rig
unattended, you should quit WSJT-X or disable Hound mode in order to avoid
the possibility of unwanted transmissions.


13.When Fox receives your “R+rpt” message he responds with “RR73”.

At this point he considers your QSO complete and logs it.

When you receive “RR73” you should log it, too !


14.If for some reason a Hound fails to copy an RR73 sent by Fox, that Hound
will repeat his transmission of Tx 3 (“R+rpt”).

Fox will respond to such “R+rpt” messages by sending “RR73” up to three
times.


73,

Tony/K4QR

(a “Hound” still waiting to get the Fox’s scent!)
