Thanks for the comment Stewart. I suspect that the advent of DSP has put the very effective Evasive Noise Blanking technique in the background, perhaps cost. I would like to try eliminating the IF Gate, and have the blanker's output switch off/on the LO drive to one of the 'H' mixers in the homegrown receiver. This should be quite easy as 'logic' circuitry provides the 50% duty cycle square wave LO to each mixer, but I would probably get myself in a muddle with timing etc. Worth trying though as then there would be no blanking circuitry in the direct signal path, other than the input which is well isolated..
