Improves performance of loop antenna on 40,80, and 160 meters. Feedback control is obtained with adjustable single-turn loop L3 coupled to L1, and receiver input is taken from L2. L3 is rotated within field.of L1 to adjust amount of regeneration, optimize circuit a, and make directional null more pronounced, Article gives loop con-struction details. Ground lower end of 100K ret sistorto provideground return for FET.-K, Cor-nell, Loop Antenna Receiving Aid, Ham Radio, May 1975, p 66-70.
