It is interesting to note that even when a band appears to be closed, there is well chances for an
open SIM31 path. Especially during weak propagation and if you want to force the contact
by your full permissible hight Tx-power or by the strenght of your magic directive antenna ,
SIM31 could be the preferred mode for you. Even weak received signals, with additional local noises,
that are -18dB S/N can
with relative ease.
received callsigns and S/N reports are
spotted automatically to the PSKReporter.info
service and to the HamSpots.net/SIM web pages. So you can see on world mape where
are you well received and at what signal report.
