[Elecraft] Noise Blanker Wish List.

[Geoffrey Mackenzie-Kennedy]

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..

The Trio TS180S had this scheme of noise blanker as well.
