Hi all,
These references are interesting, but we have to remember that we are
speaking about HF communication on short-wave bands, in half duplex
mode. None of the actors (the stations on the band) has a full knowledge
of the whole situation of the communication channel in use. Each station
has only knowledge about the stations it can see on its own receiver
during the receiving slots. This is not a global view. Further, the
situation is continuously changing because of the changing propagation
conditions. In this context, with this limited information, it is very
difficult to find the good choice in a global sense.
PSKreporter is the tool which has a better global overview, but its use
is not mandatory, not always possible and PSKreporter displays a view of
the past because of the technology used. In the context of continuously
changing propagation, this information is of limited usefulness.
When my partner station cannot copy me well, it makes sense to try to
use another TX frequency which seems to be free according to my own RX.
Perhaps, this can help, but it's not sure. If cannot see what the RX of
my partner displays. I cannot verify if my decision was good. If the
situation persists, I can just try another TX frequency again.
Best wishes,
Claude (DJ0OT)
