The OTA tests were a hoot, even with the hound-on-hound nonsense and
the unfortunate DQRM from XE.
Did anyone collect and mention the final numbers for the foxes? I
thought N1DG said ~190 for 30M, but I sense the total 40M QSO’s may
have been quite significant, since my screen was /REALLY/ scrolling
during AA7A’s hour.

Hi John,
the total Fox QSO counts mentioned on PJR included many dupes, this is
because the Fox mode logs a dupe when a repeated confirmation is
received from a Hound. This would be ok but a defect lead to signoff
messages not always being sent again by the Fox so the dupe counts were
very high. I don't have exact figures but something of the order of 1/5
of the maximum possible unique QSOs for the number of Tx slots being
used by the Fox. With the defect found and fixed so that Hounds that
have to repeat their confirmation are very likely to get a prompt RR73
response, the throughput should increase significantly.
I would expect that with a suitable sized pileup and reasonably good
behaviour, a slick Fox operator may be able to get quite close to
optimal rates i.e. <slot-count> x 120 QSOs per hour. There are a few
tools in the Foxes bag for pileup management that were not used such as
randomized Tx frequencies (helps with DQRM), directional calls (needs
thought as currently the Fox has to stop and call CQ to ask), working
weak callers first, working furthest distances first, etc..
