There is now a third party .dll ( g33ddcapi.dll ) that allows a user to run the G33DDC Excalibur Pro software with the G31DDC Excalibur hardware. This brings some of the functionality of the Pro to the regular Excalibur. I have tried it, and it does seem to work, but I have been much too busy with work to look at it in detail or to add to this thread. I have a couple of ideas of guide/help things to throw in this thread, but have not had the time to do them.
What I know so far, running the G33DDC software with the G31DDC hardware does not activate hardware features, such as 4 MHz DDC record, RF front end BPF, or the preamplifier, this should be clear and obvious to anyone, software does not add hardware

. A couple of features I thought would be software based appear to be hardware instead, and so also do not work with the Pro Software/G31DDC hardware combination, and that is the dual notch filter and the selectable SSB on ISB and DSB modes.
But, what does appear to work is the enhanced measurements capabilities, clock based time tags on waterfall displays, clock playback during DDC record, longer filter sample rates (improved filter performance), selectable RX to specific sound card outputs (VAC functionality), and several other more polished features.
Keep in mind that this is a 3rd party DLL. One can think of it as a “hack”. As such there might be issues that could void any warrantee if you decide to use the software/hardware combination. Look at it as you would any other 3rd party software, use it with caution and at your own risk.
