This project is to generate an audio HF FSK signal with a center frequency of 1700 Hz with a frequency shift of 170 Hz at 100 baud. The module will accept a string of characters (ASCII values) or numeric (0 â€“ 254) and generate the FSK for that string. Signal description is in ITU 493 that is attached.
The project must be able to incorporate into an existing vb.net (Visual Studio 2010) project but can use an external ocx. The module should simply work by calling the function SendEncoder(msg as string) and have the proper FSK signal sent to the audio out of a sound card. If using an OCX, it must be available for our use without restrictions.
Must be compatible with either 32 or 64 bit machine and have the option to select different sound cards.
A wav example of a typical signal is also attached.
Please do not bid unless you are confident you can complete the project.
We have decided that rather than use an OCX, the preferred method will be for this FSK modulator to be a stand along program and communicate via TCP/IP. The application needs configuration for ip address, ip port, etc which can be a text file that it loads upon execution. The string of data will be sent to the application that will then take it and generate the correct FSK signal out the soundcard. This can be programmed in an language, but should be common that we can modify and recompile if needed.
Please adjust your bids as needed.
