Here is the result of my new DSP transmit chain, it's an improvement over the improved one I posted yesterday, perhaps a tad less than half the bandwidth used.

Because of the big improvement in the gain of the new dec/int filters, I was able to reduce various gains applied throughout the chain: microphone gain 20dB -> 10dB, scaling factors applied in?ExciterIQData 20 -> 2.6.? Note that this is before transmit IQ calibration.

For reference, the previous image mentioned above is here and an image of the original v66-9 (prior to Oliver's recent changes) is here.
