Furthermore, the same manual has occasionally been converted into a single PDF ( SpecLab_Manual.pdf), but any attempt to create a common index and table of contents for this PDF, using OpenOffice (with proper page numbers instead of the hyperlinks) has failed miserably – see note in the preface of the PDF document.įor the most part I agree, but here is a simpler explanation of what SpetrumLabs does:

Or look into the manual (in HTML format), even though the manual included in the archive will be more up-to-date. This program started as a simple FFT program running under DOS a long time ago, but it is now a specialized audio analyzer, filter, frequency converter, hum filter, data logger etc (see history).

Here is what the Spectrum Lab web site says about Spectrum Lab: Here are the tools I used to quantify the RFI, and get set to locate it. The next article will cover how I used triangulation to locate the individual houses involved. This first article show what I did to monitor, and characterize the RFI. That way I could efficiently schedule my RFI hunting, and use the start times to verify that the same source was in fact covering several square miles of area. Once the tools were in place, all I needed to do was to define the hours of operation for the RFI. For that we needed some tools… They are both free, and they are very high quality. In order to be as efficient as possible in this, the first thing was gather as much information about the signal as possible. Each person took recordings, and each person time stamped them for later use with the FCC. It also has the same start-up sound associated. That pretty well indicates that the RFI we are all hearing is the same. We all heard the RFI start at the same moment. In this case it was pretty easy, we all started listening at RFI start time, and waited until 10 minutes. You need to tie the RFI source to each station being affected in order to be able to prove it is the same source. In order to file these reports with the FCC you need to first quantify the problems with real numbers, not just my radio is unusable but real numbers, signal levels, field strength readings around a suspect location etc. A report has already been filed with the FCC regarding the RFI levels in this area. We have the general area pinned down, and this summer, (2014), we are going to locate the house, and either contact the owner, or request FCC assistance. So there are folks who have it worse than me!Īll in all there are 6 and possible 9 hams affected by what was a single source, over several square miles, all from a single source. Yet a third fellow up the road was getting wiped out. There is another ham located about 1/4 mile from the source, he has just moved in, and was unaware why his use of 40 meters use was precluded due to RFI. this poor fellow had all ham bands wiped out, 160 Meters through 10 meters, 7X24X365, for two years. Other hams in the area, (1/2 mile away), closer to the source of the RFI have lost the entire HF spectrum. 40 Meters was unusable due to QRM last year, I am only now beginning to be able to use 40 meters again, after shutting down three RFI sources in the local area. Over the past few years my RFI problem has been getting worse and worse. Here is the legal disclaimer: None of this should be construed to be a suggestion as to what you should do, that is something you need to decide on, this is what I did, and am doing. Your mileage may vary, and you will need to remember, this is what I did, and not a guide for you, but more of a chronicle of events and actions I took to solve my RFI problem. In this set of articles, I will describe the process I used to locate and mitigate a few RFI sources around my area. Quantification, followed by location of the source, that is the first thought that came to my head when I discovered the RFI being sprayed all over the area I live in.

This first part will cover gathering the software tools I used for RFI location and removal, while part II covers cleaning your own RFI up. So I have RFI, now what– Quantification, gathering the tools:
