This Single Band Multi-mode (SSB/CW) transceiver DSP complements the Single Frequency FM transceiver in it’s application as an IF for higher frequency microwave rigs: Single Band VHF FM IF Simplex Transceiver For some operating situations an FM DSP is preferred and in other situations SSB/CW is the preferred mode of operation. It is useful and easy for an SDR system to quickly and easily choose between modes. As a practical matter, it is more simple for the operator to open an FM DSP file or an SSB/CW DSP file on the host computer rather than construct a complex DSP GRC flow graph that allows the user to select the desired mode from the operating GUI. This Multi-mode DSP features SSB/CW capability to the IF transceiver. This particular example, as with the FM DSP example, are tailored to my 24 GHz rover station.
