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. 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  be  decoded
with relative  ease.

 All  received   callsigns   and  S/N  reports  are  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.
