For increased selectivity and reception capability of receivers which utilize a 455 khz IF frequency. From the 1962 Heathkit catalog - “Provides an effective 'Q' of 4,000 for peaking or rejecting a signal on AM, CW, or SSB. Produces a sharply peaked I.F. curve for CW reception, broad peaked I.F. for phone operation or a deep rejection notch to eliminate a closely interferring heterodyne. Both peak or notch positions are tuneable to any point in the receivers I.F. bandpass.” The unit is in excellent condition.
