On the HamRadioHelpGroup, a new ham asked:
I was wondering if there are any .wav files out there that can help one identify different kinds of noise and interference. I get all kinds of crazy sounds of my radio. Some sound like they may be data, others sound like someone is broadcasting a truck engine. Any ideas?
Of course, answers were quickly proferred:
I believe I’ve written before about the Digital Modes Sample page, but the RFI Noise Identification page was a new one for me. The page has 20 or more .mp3 files of various types of noise in the following categories:
- Household appliances and electrical equipment
- Computers and related equipment
- Transmitters and intentional RF emitters
- Electric Utilities , BPL and industrial equipment
- Miscellaneous Equipment
There are also a bunch of unidentified noises. Have a go and see if you can id them.
