SIM31 & SIM63 Ham Radio HF digital modes
This is the Page For SIM31 & SIM63 Radio HF digital modes (Nizar Ben Rejeb).

SIM31 “Structured Integrated Message" is a new robust digimode specially designed
for making reliable & confirmed QSOs under extreme conditions on all amateur bands.

 

It is interesting to note that even when a band appears to be closed, there is well chances
for an open SIM31 path. If you have a restricted antennas, power or both, SIM31 could be
         the preferred mode for you. Signals that are -18dB S/N on 3000 Hz equivalent noise bandwidth,
can be decoded with relative ease. All received stations, with S/N reports, was spotted

    automatically to the PSKReporter.info map 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.
