SAF Tehnika has an awesome spectrum analyzer that covers 18GHz and it
isn't too expensive. That would allow you for instance to shut down
your radio during interference events and take a measurement and from
there you can take your spectrum hunting on the road.

In my ongoing saga of troubleshooting an 18ghz link, we think we're
pretty sure the issue we are having now is Noise. From around 7am -
noon or 1pm, the background noise on my Horizontal polarity goes to
about -81. Has anyone had to troubleshoot finding the source of noise
on a licensed channel? Do you just start contacting everyone on the
same channel within a few miles and see if they will disable their
transmitter to see if it goes away?
We have found 2 other licenses which are pointing kind of at us. If I
point my dish (in RX only mode) at one of the transmitters, which is
10 degrees off my path (I am 4 degrees off their path), I hear it at -70
The Other license is for one of the Day Traders. The GPS Coordinates
in the License put it 20 degrees off my path, I know there is no dish
where the GPS Coordinates say. However, if it's where I think it
might be (on a pole on the other end of the building), then it's
basically pointing at me. Although, with it being a Day trader,
there's a good chance it was never installed, or has been
decommissioned. Those guys throw licenses and dishes up and down like
yesterdays fashions.
Any Tips for the next step?
