Dave - is this actually REALLY quickly synchronized separate transmissions to 3
different stations? Or are there 3 simultaneous transmissions occurring at
exactly the same time? If it’s the former, its certainly serial single op
worthy - I do this all the time while contesting - just not as fast as a
computer. If it’s the later, then it would be "more than one signal at a
time". That would violate current rules in all categories I believe. Even
Multi-Op stations can only have one signal at a time on a distinct band. Of
course I am assuming that a "signal" is the roughly 50hz of individual beeps
and not the 3khz of computer managed bandwidth. All definitions to be
finalized with this new breed of contest category. Illustrating how non-human
controlled it really is.
Interestingly, and on a different subject, whether 5T5PA is actually compliant
with the new DXCC rules making such contacts ineligible for DXCC is another
topic. I believe that the next contact cannot be made without a human
engagement. So was it semi-automatic or automatic fire? And is that
engagement needed as part of a "stack build" or real time - the initial DXCC
language was not too clear.

Subject: [CQ-Contest] WW-Digi Contest -- Rule Clarification
Although it is certainly implied, the rules listed on the WW-Digi website do
not specifically prohibit using more than one signal at the same time ON THE
SAME BAND for the single op category. They say that transmission can only be
on one band at a time, but they don't say you can't make multiple transmissions
at the same time on the same band.
The reason I bring this up is that I just witnessed 5T5PA making three separate
FT8 transmissions on 20m to three different stations all within the same
fifteen second window. A short time later I saw two separate transmissions
from him to two different stations (and different stations than the previous
three), again all within the same fifteen second window. Each simultaneous
transmission was spaced exactly 60 Hz apart, and the software cleanly decoded
all signals as if they were from different callsigns. 5T5PA expertly managed
all the QSOs cleanly.
Interestingly enough, even though I've worked 5T5PA before, JTAlert only
labeled one of the three as a dupe.
I can think of more than a couple of ways 5T5PA could be doing this, and for
casual operation I see no problem with it. For a DXpedition, it might even
make a lot of sense. I don't remember it being against FCC/other laws, but I
could be wrong about that. In any case, it seems to me that it could open up
the possibility for some controversy in a contest.
Or maybe I'm just crying wolf here ...
