FT8 Fox/Hound examples by OZ1BXM
TY0RU Benin
Distance to DX-station: 5,600 km
Transceiver frequency = 24.915 MHz
TX Output: 10 W
Antenna: Horizontal loop (43 m long)
WSJT-X ver.2.5.4 (General Availability Release)
Enable Hound mode in WSJT-X: File > Settings > Advanced > Hound
Set RX to the frequency where the DX is transmitting (1093 Hz).
Set TX to a higher frequency where nobody is transmitting. I've chosen 2382 Hz.
Type "TY0RU" in the DX-call field and press "Generate Standard Messages". The messages are shown in figure 1.
Uncheck "TX Even" because DX is transmitting at 00 or 30 and you should transmit at 15 or 45.
Explaining figure 2:
120630: DX calls CQ.
120645: Press the "Activate TX" button to transmit on the chosen frequency (2382 Hz).
120700: DX answers my call on a lower frequency (1153 Hz) than I transmitted on first.
120715: I send R-09 to the DX on 1153 Hz. WSJT-X has automatically moved my TX there.
120730: I receive RR73 on 1153 Hz confirming our contact. QSO completed.
