MISC - Timewave ANC-4 HF noise reduction unit. 5 TIMEWAVE ANC-4: The Miracle of phase shift active noise cancelling ... The Timewave ANC-4 is a phase-shifting RF noise canceller designed for amateur radio and shortwave listeners to eliminate locally generated RF interference. It works by receiving the offending noise on a separate noise antenna and then canceling it by shifting its phase to oppose the main signal received by the primary antenna. The ANC-4 is effective at reducing specific, localized noise sources like computer, power line, and inverter noise, though it does not remove broadband noise. Unit runs on 12V. Manual available online. I’m asking $125.00 plus shipping.
