Tracking Down Interference

I started getting more diligent on the weaker, less annoying birds in my system. I started by logging them in dx.json using the Identifier QRM. Next, I logged into the kiwi via ssh and used grep on the dx.json file, grep QRM dx.json > QRM. That gave me a file of all the freqs that I had identified as qrm sources. Now i can look at harmonic relationships etc and try to determine a source.

in this directory

root@kiwisdr:~/kiwi.config#

use grep

root@kiwisdr:~/kiwi.config# grep QRM dx.json > QRM

sample result via command cat QRM
