inmarsat c decoding software for p25 scanner

But to be unquestionably legal a full two man clean-room rewrite would probably need to be done as once knowledge of source code is acquired it can be difficult to think of a separate implementation (a somewhat related post discussing this on StackExchange). Since then microp11 notes that he has written Scytale-C fully from scratch without the closed source code knowledge.

After Alex took action and micrcop11 realized what he did was wrong he took B4000Hz down. Originally the software was illegally decompiled by 'microp11' from the closed source Tekmanoid STD-C decoder written by Alex and re-released in a different programming language with a different GUI as the 'open source' B4000Hz software. We feel that it is responsible to make a note on coding and licencing ethics about this software. otti DecemScytale-C Screenshot An Important Note on the Coding Ethics of Scytale-C + Tekmanoid Decoder Updates We've also seen on Twitter that Scytale-C beta tester has noted that a SDR# plugin based on Scytale-C seems to be in the works.Ī new SDR# multichannel decoder plugin for Std C? Too good to be true. The tutorial can easily be adapted for use with Scytale-C instead. If you are interested we have a tutorial based on other software packages available here which also shows some STD-C message examples. On the STD-C channel you'll see messages mainly for mariners at sea such as weather updates, military operational warnings, pirate sightings/reports, submarine activity, search and rescue messages and more. The satellite is geosynchronous (stationary in the sky), so no tracking is required. This means that the signal can be received with a simple patch antenna, LNA and RTL-SDR dongle. Inmarsat STD-C is an L-band geosynchronous satellite signal that transmits at 1.541450 GHz. exe file can be downloaded from the downloads section of the BitBucket repo. The software is available for Windows, and a ready to use binary. Over on the BitBucket code repository a new open source decoder for Inmarsat STD-C called Scytale-C has been released.
