Here is updated VHDL code for the IQ Gain and Phase Correction filter.I'm working with an adjusted numbering scheme in signed arithmetic to correct an overflow problem (thanks to KB5MU, who helped identify). This implementation, which is designed to be synthesizeable, is beginning to function as intended. There is a factor of two error, but the compiled block outputs I and Q. With some data visualization, these might prove to be a passed-through I and phase corrected Q at the output, with a massive gain overcorrection. I'll check that tomorrow! -Michelle W5NYV
