8. ing an existing transceiver is that today s commercial amateur radios are very rugged and they also have a very good IP3 intercept point All the other low priced SDR hardware is very prone to cross modulation in strong signal conditions Now with the additional modulator the MDSR software can upgrade older shortwave transceivers to the latest SDR interface with all the DSP features only found in high end units The BiLIF interface takes advantage of the sturdiness of commercial radios and the MDSR provides the graphic user interface and signal processing An existing radio can be upgraded and enhanced without a lot of expense Changes and updates in the MDSR SA software release Summary The MDSR Team has been hard at work developing the next step of the DADPsoftware The MDSR synthesizer provides a full RX TX capable DSP engine and utilizes the soundcard to convert the digital audio stream into an analog 12kHz TX IF output The MDSR SA is the companion software and was derived from the DADP SA The development of the original CAT interface was discontinued and instead the OmniRig CAT interface was implemented for greater functionality and compatibility with 48 transceivers Modulation Demodulation Software Radio The MDSR software offers the following features MDSR SA spectrum analyzer and function display MDSR OmniRi 6 Memory banks to store popular frequencies and fast recall new Arduino frequency counter interface
