On 80m I don't think the international sub-bands play very much of a part
for most of the U.S., rather it's the NA to NA QSO's and low-power CW
stations competing for spectrum with high-power RTTY that is the rub. If
RTTY stayed mainly above 3570 that would be fine but we know when things get
crowded, as it surely will on 80m this time of year, stations will seek the
open spaces. That means there will likely be RTTY as far down as 3530 or
lower.

Yes, but less so. While basically the same amount of spectrum, the sub-band
usage is different. The JA RTTY sub-band is 3520-3525, but for NA
propagation, that will be long after NAQP is over. The rest of the world
that NA can readily hear on 80 meters, i.e., NA and EU, will be above 3570.
The only significant conflict is on 40 meters where EU operates as low as
7030, sometimes lower. Moreover, RTTY contesters will be running in that
area long before NAQP gets to 40. The NA stations RTTY stations in those
QSOs will be the most bothersome to NAQP. If the contesting world can
survive a few hours on that Saturday evening, it won't be an issue again
until 2022, if then.
