Kudos to FRS for listening. The APF is a pleasant surprise. It works well. Thanks Gerald.
Saw on the DX cluster that JT1CS was on 12 meter CW tonight. Band was virtually dead and although I knew he was in the noise floor, I could not copy him, even with the 20 db pre-amp on. Went back to the 10 db pre-amp, turned on the APF, and BANG.....there he was...569 and perfect copy! I realize the conditions were perfect for APF, but what a dramatic tool to have in our arsenal. (Worked him, by the way)
