New RF Noise Identification Website:

I'd like to draw everyone's attention to a new website I'm just putting the finishing touches on, called The RF Noise Identification website.

It's purpose is to help hams and SWLs like you and me to identify the noises (QRN) that intrude on our listening. The web page contains a growing library of recordings in MP3 format that you can download or listen to while at the page. The recordings are of various types of noises from known sources and some that haven't been identified. I have also included small waveform images that provide an additional "fingerprint" for identification.

My hope is that users will visit the site if they have QRN problems and be able to identify noise that's bothering them by comparing it to the recordings. I would also greatly appreciate contributions in the form of recordings of noises at your location as well. I will convert them to MP3 format and add them to the web page (with credit to you) for all to listen to. WAV or MP3 files, audio cassettes or CDs will be gratefully accepted. See the website for additional details.

Shortly after completing the website I showed it to Ed Hare, W1RFI and Mike Gruber, W1MG, two of the RFI gurus at the American Radio Relay League (ARRL) Lab. I believe they liked what they saw, and I was asked if I would like to help manage a Sounds Of RFI website for the ARRL - a project they've had in their minds for a while but didn't have the time to implement. I happily agreed and was deluged with over 30 new noise files they've been saving up! These are being added to the site as I have receive permission from the original contributors. Eventually, all files will be shared between my RF Noise Identification site and the ARRL's Sounds of RFI site for the benefit of everyone. The ARRL site should be up in a few weeks.

I'd appreciate your comments, suggestions, and contributions!
