    An active audio filter for analog processing of received radio signals to enhance listening and reduce interfence. AutekQF1.jpg Connects between a receiver's phone or speaker out jack and a speaker or headphones and selects or rejects certain frequency components of signals tuned in. It rejects undesired signals such as noise and interference while passing the desired signal, as long as the noise and desired signal are not on the same frequency.

    This unit is used, very good condition and comes with a color copy of an original manual.

    $50 shipped to USA by USPS Priority mail, insured. PayPal, USPS Money Order, or personal check (2-weeks delay in shipping for check clearance.)
