It's not a Weaver modulator, but G3PLX's SDR transmitter that generates I/Q outputs from a soundcard and also, in a very clever way, allows FM and AM to be generated when no DC component is present.  Read the accompanying documentation to see how it's done.

All can be found here: http://www.g4jnt.com/SDRTxSW.htm

Well the main purpose of the filter is filtering. Letting it produce an I/Q output is more or less a by-product, and it works extremely well.

That seems a very convoluted (!!) way of doing what is actually quite a simple process.
