Yes indeed, the PSKReporter spotting system is an excellent way to study 
propagation. I've used it extensively on 6M for this purpose, AND to 
chase QSOs with stations in grids I want to work.

I've been using the modes developed by K1JT and his team extensively for 
nearly ten years, almost exclusively on 160M during the winter to fill 
in EU countries from my QTH near San Francisco, and on 6M to chase grids 
during the summer e-skip season. I'll use FT8 to work expeditions on HF, 
but I have yet to get bitten by the bug to use it during contests.

My engineering judgement is that FT8 is able to work about 10 dB deeper 
into the noise than CW with great operators on both ends of the QSO. I 
STRONGLY encourage 160M operators to use the newer and even more 
powerful FST4, which provides an additional 4-9 dB advantage, depending 
on the transmission period.

For those who consider these modes "not real ham radio, computers 
talking to each other," I know no one who can send or decode RTTY using 
only their ears, and the computer did not learn CW, radio and 
electronics, nor did it build my station, including my extensive antenna 
farm over 15 years.
