[Lowfer] Old water softener RFI recordings?

[KD7JYK DM09]

I recall in the late 90's when electronic "water softeners", and 
"de-scalers" were becoming popular, and wiping out LowFER, and some ham 
bands across the US, and Europe, there were a few pages dedicated to the 
noise produced by the horrible devices.  One in particular had numerous 
recordings of various makes, and models, and operating in various modes. 
  I recall the audio samples provided were in the .rm format.  I saved 
them, but it could take literally months, or years for me to find them.

Does anyone recall the webpage, or have any of the old audio samples or RFI?

Thanks.
