SIM31 & SIM63
Ham Radio HF digital modes

This is the Page For SIM31 & SIM63 Radio HF digital modes (3V8MN 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.  and if you want  to force the contact by your  full permissible hight  Tx-power
or by the strenght of your magic directive antenna ,
Especially during weak propagation,
SIM31 could  be  the  preferred  mode  to help you Dxing. 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.
