Well, I admit I didn't know that. If that's the case, it would
certainly make for an interesting situation in a contest. And if
everyone can rather easily have that functional capability, I'm not even
sure I have a problem with it. Given the way FT8/4 works, I'm not even
sure it would increase the QRM. You'd still have the same number of
It would certainly add an additional degree of operator focus to the
game, and as Randy says in a different post, the new digital modes are
probably going to redefine how we look at some things.

>> Well, I've read the contest rules several times, and they don't specifically make the same "one signal per band" limitation for single op that they do for multiop. I agree that it is assumed, but again ... the rules don't specifically rule it out and we all know from past experience that loopholes tend to be exploited.
>> And I am absolutely certain that these were three separate QSOs with three different stations. I should have taken a screenshot. The contacts were within the same 15 second window, with different stations, and with different signal reports. And as I said, it happened again a short while later with two completely different stations. These were not images, and they were not the staggered transmissions that we can do while overlapping more than one contact.
>> I'm pretty sure you can run multiple instances of WSJT-X as long as you specify different rigs for each. If you check out 5T5PA's page at QRZ.com you can clearly see that he is a pretty smart guy and that he has multiple rigs. Probably the simplest way would be to use three instances of WSJT-X driving the same sound card and talking to three rigs via different com ports.
>> Regarding DXCC eligibility, what I saw did not appear to be any more automated than normal FT8 contacts. They didn't need to be. If he called CQ on three different frequencies, WSJT-X handles everything from that point on if he clicked the "Call 1st" box. He would still have to manually enable the next CQ's, but that wouldn't be difficult to quickly do three times.

>>> 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.

>>> 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.
