CODE300-32 is a software based DEMODULATOR, DECODER and ANALYSER which runs under all actual Microsoft Windows operating systems, W98, WIN 2000,NT4, WIN ME and XP. This program is part of a new generation of Data Decoder Analysers and follows the well-known DOS based decoders CODE3.

A lot of new functions and ideas could be realized in this 32-bit WINDOWS release.

The program uses the integrated sound device(s) of a modern PC while running under Windows as the AD/DA device. The software does not need an expansion slot nor any dedicated hardware to function.

This solution is the most flexible way to use the decoder on any PC or notebook. Some of the modern sound devices offer very good performance when compared with industrial AD cards.

A modern 66 MHz DSP device is compatible with a very old Pentium CPU with a 130 MHz clock speed. We do not know a DSP with 500 MHz or more, which would be compatible with a modern 1GHz processor.

So in our opinion the PC with its cheap but very good hardware is the ideal solution for a modern state of the art data decoder analyser.

CODE300-32 keeps our long experience with software based DSP, but is completely different from the DOS based versions. Every module, analysis or decoding, is completely independent and can be used stand-alone. This offers a complete new world in utility decoding. The program uses the soundcards left input channel as its main source but any additional module can be switched to the other input channel or remain ‘listening’ to the main input. This allows the decoder to run multiple modules from two independent sources.

As an example a MORSE decoder is running together with a SITOR decoder on left channel audio input to enable decoding both types of traffic without a switching gap or manually users handling. The second channel input decodes a VHF PAGER system like POCSAG at the same time. But you might miss a FLEX message, no problem open a FLEX module too and select the right input source.

While any module is open the main FFT window is always running for tuning control and signal checking.

Besides this the new CODE300-32 is a DAT recorder with unique functions. You can record one or both channels completely independent from the decoding modules and then at a later time play these back into the decoder and perform more tasks as-if the signals were live data. The data format can be specified in the decoder set-up but for most users 11Khz and 16bit MONO do just fine. Note this is in standard WAV format so you are free to use the audio with other programs or it can be stored as a reference for future use
