MFJ-1025


It works great for man made noise. JPS made a unit called ANC-4, then Timewave bought them out. That's the one I had. I imagine the MFJ unit works the same. The important thing is to be patient. Depending on the noise source, it can take a great deal of experimentation getting it to work. Follow the directions carefully.

They do little to alleviate atmospheric noise, though.

Flexible DSP noise-canceling unit with high-performance audio processing - New lower Price!
The bhi Dual In-Line amplified DSP noise-canceling module uses a powerful high-performance audio processing system and unique DSP noise-canceling technology to distinguish speech signals from noise and interference. This results in clear intelligible speech under most conditions. Your listening experience will be greatly improved with the processed speech sounding much clearer and more intelligible without all the noise, especially when trying to listen to weak signals.
