Nonlinear junction detector

Post by Eagle72 » Thu Jan 10, 2019 2:32 pm

Hi.

Have 2 questions hope anyone can answer.

1. Im wondering if anyone know if its possible to build NLJD by using hackrf , what i know so far is it uses harmonic radar to detect electronics by transmitting highpower uhf 1-3.6 GHZ to specific nearfiled area... Since hackrf can transmitt up to 6ghz it should be possible or does it need to be fullduplex? Anyone who undertand this better know if this is possible by building 2 antennas and mount them above the hackrf and place it on a stick and connect to phone/lamptop to see reactions?

2. I have seen very intresting software used for sweeping for hidden rf-gsm bugs used for Delta x 100 which is quite expensive buts its software seems to be very good... is it possible to modify driver files to get it work with hackrf?

Delta X uses Signal Hound hardware and it seems as they have developed a opensource software from siggnalhoud which is avlivable for download... here : https://signalhound.com/software/signal ... t-kit-sdk/

Here is the program for Delta X100 : http://www.sweeping-tscm.com/downloads/Delta-X64_12.php

I think you would need full duplex unless you have a seperate signal source.
