** The spotting revolution
** The marginal bands revolution
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.
With FT8, marginal bands like 160, 10 and 6 meters become alive like no
other. Going deeper into the SNR, “opens” new circuits, brings more
activity, confirms these circuits were always there. We are working Japan
on 6 meters on a daily basis... Also, there is a move from CW into FT8 on
these band. This is a side effect, but it is what it is. If people suddenly
find a band open at -21dB that before was close at -15dB, of course they
will use the mode that enables those QSOs and will not use the other mode
anymore.
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.
