First of all, sorry for my English.
This site (sorry in Russian) is offering radardetectors which use "direct amplification" instead of superheterodyne. By me (maybe I'm wrong)
it should mean that there is no LO-leakage at all as there is nothing to leak.
The price is from 12 to 30 USD. BTW, they sell STi for more than 800 USD. :shock:
What do you think about that?
I can try to get one and send it to DET for testing...
P.S. I've done some search here - nothing about direct amplification.
