This morning it took three attempts to finally work ZK3A on 80M FT8 in
the F/H mode. In the first two attempts, after ZK3A answered me, my tone
frequency was moved to their TX tone frequency as was expected. Then for
two transmissions, they sent calls and reports but did not copy the
Rogers and report that I sent each time. After not acknowledging my
second "ZK3A K1HTV R-01" report I noticed that WSJT-X had shifted my
tone frequency to around 600 Hz. The first time this happened, I did not
decode ZK3A's transmission immediately following my second report
transmission. After sending an number of calls and reports to ZK3A with
teh 600 H tone, I restarted from scratch, calling ZK3A with the TX1
message using a tone frequency above 1000 HZ.
The second time ZK3A answered, again I called twice with no RR73 from
them and again was shifted by WSJT-X to a 600 Hz tone. This time I did
copy the ZK3A transmission which showed them calling other stations,
apparently giving up on my call again.
Fortunately my third try was a charm and I did finally receive a RR73
from ZK3A for my 80M country #121 with 75 Watts.
My questions are:
1) After two unsuccessful attempts to receive calls and reports from a
Hound that the Fox has answered, when the WSJT-X moves the TX tone of
that Hound to 600 Hz, does it mean that the Fox has given up on that Hound?
2) If the Hound continues to call on the 600 Hz tone frequency, will the
Fox ever respond. If not, the Hound needs to restart the calling process
with a TX tone greater than 1000 Hz.
Upon receiving a report from Fox, Hound's audio frequency is moved to
that of Fox. Hound can make two tries to be copied at that frequency.
If Hound still has not received RR73, Hound's frequency is increased by
300 Hz for subsequent tries.
Fox abandons a QSO attempt with a particular Hound if any of the
following becomes true:
1. More than 6 of Fox's Tx cycles has elapsed since Fox sent a report to
this Hound.
2. More than 3 of Fox's Tx cycles has elapsed since Fox sent RR73 to
this Hound.
3. Fox sent a report top this Hound more than 6 times.
4. Fox sent RR73 to this Hound more than 3 times.
